A clearer understanding of human or social aspects of environmental issues will enhance conservation. While social acceptance is critical in determining MPA success, it continues to be an inadequately explored area of research. This study examined the acceptability of the proposed Marine Protected Area in Ozamiz City, Philippines. Stressing the significance of social acceptability to an MPA's successful implementation, this investigated the influence of the fishing households' knowledge of the marine environment and coastal resource management and the perceived condition of the coastal environment on the social acceptability of a proposed MPA implementation. The study used a mixed-method, particularly concurrent triangulation design, utilizing a sample of 270 fishing households in the 15 coastal barangays of Ozamiz City. The data were gathered through a survey supplemented with key informant interviews (KII). The study revealed that the knowledge of the marine environment and coastal resource management had shown a highly significant relationship and emerged as a predictor of the social acceptability of the proposed MPA. Therefore, greater knowledge of the marine environment and coastal resource management among the fisher folks and stakeholders, in general, may result in a higher level of acceptability of the proposed MPA, thus resulting in a successful implementation. Strategies must be implemented to enhance and enrich the fisher folks' knowledge of the marine ecosystem and coastal resource management. Information on the features, characteristics, and importance of the corals and coral reefs to the marine ecosystem should be emphasized. [ABSTRACT FROM AUTHOR]

Medium‐ to large‐scale marine protected areas (MPAs) are playing an increasingly important role in global marine biodiversity conservation. A key question is "how do we collect relevant data on biodiversity and population trends to inform their design and measure success?"This question is particularly relevant for marine taxa that are difficult to survey, such as sharks and rays, and where populations may occur over vast areas. Environmental DNA (eDNA) metabarcoding has proven to be an effective sampling method and may provide a solution to these challenges; however, it remains unclear how its sampling effectiveness compares with traditionally used methods for elasmobranch surveying.Here, we directly compared the efficacy of eDNA metabarcoding and demersal longline deployments to survey elasmobranchs across 31 sites over a 55,000 km2 area of the Kimberley and Roebuck Australian Marine Parks in Australia's North‐west Marine Parks Network.In total, we documented 49 unique elasmobranch taxa, 36 of which were detected by eDNA and 32 (from a total of 815 captured sharks) by longline. A combined approach yielded over 34% more elasmobranch taxa than either method alone.Site community compositions varied between the two survey methods; notably eDNA was able to detect species from outside of the immediate sampling area, although this was still consistent with a detection radius of a few kilometres, highlighting a particular use in rugose reef habitats where it is difficult to deploy longlines.In investigating the quantitative use of eDNA data, we report that eDNA metabarcoding read abundance (count) data was poorly correlated with longline aggregate catch (count and biomass) data across raw, relative and rank abundance measures. However, we found that in multivariate analyses, both binary (presence–absence) and abundance (after square‐root transformation) datasets produced highly similar ordination patterns, largely segregating method (eDNA vs. longline), followed by latitude and depth.Lastly, we identified required levels of eDNA replication and longline deployments to maximize captured elasmobranch diversity.This study sets an integrated, georeferenced baseline and long‐term monitoring approach for the management and conservation of elasmobranch diversity within this unique marine park network.

Studying fishers and fishing communities' social‐cultural structures is vital in policy‐making concerning local marine ecosystem sustainability. Previous studies on marine communities seldom neglected the role of culture in marine biodiversity conservation, especially a marine protected area (MPA) establishment.This study first explores the cultural practices in coastal communities in Ghana that have the potential for the conservation of the marine ecosystem (MPA); second, it examines the willingness of coastal communities to welcome an MPA establishment.Primary data were collected using focus group discussions with 9 fishermen, key informant interviews with 20 chief fishermen, and self‐administered questionnaires to 491 fishermen across 9 semi‐urban, 2 urban, and 16 villages along the coast of Ghana.Adopting the convergent parallel mixed‐methods research design (quantitative method includes descriptive analysis using tables, charts, diagrams, and χ2 bivariate analysis; and qualitative method involves a narrative format), the study underscored that the socioeconomic characteristics of fishermen are diverse and mixed. Most of the fishermen do not know what an MPA is but are willing to accept an MPA initiative. Certain cultural practices such as the prohibition of gathering certain species, traditional close season, and fishing holidays are found to be conducive to an MPA initiative.These cultural practices should be integrated into an MPA policy. Fisheries practitioners should consider an ecosystem‐based approach (including cultural values) to fisheries management and fishermen should endeavour to learn new skills outside the industry.

Marine protected areas (MPAs) are the most widely applied tool for marine biodiversity conservation, yet many gaps remain in our understanding of their species‐specific effects, partly because the socio‐environmental context and spatial autocorrelation may blur and bias perceived conservation outcomes. Based on a large data set of nearly 3000 marine fish surveys spanning all tropical regions of the world, we build spatially explicit models for 658 fish species to estimate species‐specific responses to protection while controlling for the environmental, habitat and socio‐economic contexts experienced across their geographic ranges. We show that the species responses are highly variable, with ~40% of fishes not benefitting from protection. When investigating how traits influence species' responses, we find that rare top‐predators and small herbivores benefit the most from MPAs while mid‐trophic level species benefit to a lesser extent, and rare large herbivores experience adverse effects, indicating potential trophic cascades.

Understanding the habitat shifting pattern is a prerequisite for implementing in situ conservation of migratory species. Spotted seals (Phoca largha) inhabiting the Yellow Sea ecoregion (YSE) comprise a small population with independent genes and represent a charismatic flagship species in this region. However, this population has declined by 80% since the 1940s, and increased support from the countries around the YSE is urgently needed to address the potential local extinction risk. A time‐series niche model and life‐history weighted systematic conservation planning were designed on the basis of a satellite beacon tracking survey (2010–2020) of the YSE population. The results showed clustering and spreading shifting patterns during the breeding and migratory seasons, respectively. The closed‐loop migration route formed in the YSE indicated that this population might be geographically isolated from populations in other breeding areas around the world. The conservation priority area (CPA), with an area of 19 632 km2 (3.58% of the total YSE area), was the most effective response to the potential in situ risk. However, nearly 80% of the CPA was exposed outside the existing marine protected areas (MPAs). Future establishment of MPAs in China should strategically consider the conservation gap identified herein, and it is recommended for Korea's closed fishing season to be spatially set in the western Korean Peninsula from May to August. This study also exemplified that the lack of temporal information would lead to the dislocation of niche modeling for migratory species represented by spotted seals. Attention should be paid to protecting small and migratory populations in marine biodiversity conservation planning. [ABSTRACT FROM AUTHOR]

The marine ecosystem's balance is crucial for sustaining biodiversity and supporting fisheries. Marine protected areas have been increasingly used to enhance marine habitats, yet their impact on fish populations remains a topic of debate. This study focuses on a marine protected area in Kitros, Pieria, in Greece, where an artificial reef was constructed, to understand its influence on coastal fish populations. The objectives were to investigate the changes in fish biomass and abundance, comparing the data from periods before and after the construction of an artificial reef. This research compares the data between 2007 and 2008 with the data between 2016 and 2017, collected with bottom trawl surveys strategically executed prior to and after the artificial reef's installation. Fish species captured were identified, with their lengths and masses measured. The findings indicate an increase in the biomass and abundance of certain fish species after artificial reef deployment, notably the commercially significant Mullus barbatus and Pagellus erythrinus. The artificial reef in Kitros, Pieria, with its surrounding marine protected area appears to have had a positive impact on the local fish populations over the years, suggesting that it can contribute to marine conservation and fishery enhancement. These results underscore the potential of artificial reefs as tools for marine ecosystem management, offering insights for policymakers and environmentalists into coastal resource management.

The recent adoption of a new agreement on the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction has been welcomed as a historic achievement that will herald a new era of marine conservation and global ocean governance. This article aims to raise and discuss some questions, as the dust settles, and to analyze selected aspects of the text of the new Agreement, with particular respect to Part III of the BBNJ agreement, dedicated to area-based management tools (ABMTs), including marine protected areas (MPAs), which are arguably crucial for the operationalization of the Agreement but remain ambiguous or underarticulated, and may thus reduce its effectiveness and ambition. These questions concern the relationship with other relevant instruments, frameworks, and bodies (IFBs); relatedly, the issue of recognition of area-based measures adopted under other IFBs; and the so-called opt-out question, that is, the right to make objections to an ABMT and/or MPA adopted under the BBNJ agreement.

Marine protected areas (MPAs) are one of the policy tools to support marine biodiversity conservation and sustainable use of marine resources. The distribution, sources, and ecological risk assessment of persistent organic pollutants (POPs), including polycyclic aromatic hydrocarbon (PAHs), total petroleum hydrocarbons (TPHs), polychlorinated biphenyls (PCBs), and heavy metals (HMs) in sediments of MPAs in the northern Persian Gulf, were evaluated for the first time in this study. The Σ16PAHs ranged from 4.65 to 20.86 μg/kg dry weight (dw). The molecular ratios and ring's pattern of PAHs suggested a mixed origin with a predominance of pyrogenic sources. The TPH concentration varied from 5.21 to 17.90 μg/g dw. Ecological risk assessment suggested that sediment samples in Bushehr Province's MPAs can be categorized as medium risk. The mean concentration of ∑18PCB was 0.345–0.419 ng/g dw, and the main components correspond to PCB-77, PCB-105, PCB-81, PCB-101, and PCB-114. The mean concentration of As, Co, Cr, Ni, V, Mg, Pb, Zn, Cu, Al, and Fe varied from 4.79 to 9.69, 2–12, 39–142, 18–90, 15–58, 184–425, 7–45.9, 6–42.4, 4–20 μg/g dw, 0.75–4.12%, and 0.35–1.62%, respectively. Multivariate analysis, such as principal component analysis (PCA) and cluster analysis (CA), coupled with correlation coefficient analysis, was used to analyze the analytical data and to identify possible pollution sources. The results of this study provided the background information on the extent of POP contamination in the sediment and highlighted the need to further control pollution in MPAs. [ABSTRACT FROM AUTHOR]

Climate change is affecting rocky reef ecosystems in a multitude of ways at global scale. During summer 2018, the rocky reef communities of Portofino Marine Protected Area (MPA) (NW Mediterranean) were affected by thermal anomalies, a mucilaginous event, and the seasonal expansion of Caulerpa cylindracea. Moreover, a severe storm occurred on 29 October. The effects of these pressures on the rocky reef communities were analysed at different depths (10 m, 20 m, 30 m, and 40 m) and at three times (June, October, December) to evaluate change at short temporal scale. Portofino MPA's communities have significantly changed: thermal anomalies mostly affected the biota living above the summer thermocline (ca 20 m depth); mucilaginoius aggregates first impacted the communities in shallow waters and only later those in deep waters, where they typically fall in late summer; the greatest impact by Caulerpa cylindracea was detected at 20 m depth; the storm directly impacted communities in shallow and intermediate waters by uprooting algal species, while it had indirect effects at greater depths through sediment redistribution. Disentangling the effects of multiple pressures on coastal ecosystems is one of the most pressing goals in marine ecology and biodiversity conservation. This study represents an attempt in this direction as applied to the short-term dynamics of rocky reef communities under a climate change scenario. [ABSTRACT FROM AUTHOR]

The effectiveness of marine protected areas is a timely issue, as the fight against biodiversity loss depends significantly on how effective these areas are. This article explores a key condition for meeting the challenge of improving conservation policies, as part of the global targets for biodiversity conservation, following the 2022 Kunming-Montreal Global Biodiversity Framework. The paper explores the determinants of social acceptance of Marine Protected Areas (MPAs) by local communities impacted directly by MPAs designation. We focus on the Port-Cros National Park (France), which was established in 1963. The park has seen its governance, perimeter and internal zoning evolve over time, generating local opposition and underlining the importance of acceptance by local communities. This article highlights the factors that play a role in the social acceptance of this National Park based on the results of a questionnaire survey including 569 residents of the municipalities in and around the protected area. The approach we followed is part of a European research project that has developed a methodological protocol to identify interactions between social parameters that characterise the level of support and has been applied in 20 national parks. Our results reveal a high level of social acceptance for the National Park, with four main factors influencing acceptance: perceptions of the social impacts of the park, trust in management authorities, sociodemographic characteristics and conditions for citizen participation. Spatial disparities are also demonstrated. Our analysis also enables us to explain the components of constrained acceptance: this opens possibilities to explore the conditions under which local communities can feel more empowered and participate in the governance of the protected area. • The Port-Cros National Park is highly supported by local communities. • The national park has a greater impact on the inhabitants of the islands in the heart of the park. • 4 main parameters influence social acceptance: perception, trust, socio-demographics, participation conditions. • Constrainted acceptance is linked to negative perceptions of social impacts and distrust of the national park authorities. • Residents wish to be involved in decision-making, raising the challenge of inclusive and innovative governance.

Simple Summary: Plastic pollution presents a growing concern for marine biodiversity, and among these, anthropogenic particles (APs) are entering marine ecosystems at an alarming rate from land and sea sources. In this study, we quantify the ingestion of APs across fish, sea urchins, sea cucumbers (echinoderms), bivalves (molluscs), and jellyfish (cnidarians), identify biotic and abiotic factors that might influence the ingested items; and identify ingestion patterns based on taxonomic groups, trophic guilds, and habitats. Ingestion of APs was observed in the majority of the species analyses with occurrence ranging from 0% to 100%. The study results indicate that plastic pollution poses a threat to species found within the marine protected area of the Cabrera Marine-Terrestrial National Park despite their protection status. The multispecies approach provided a better understanding of the high level of AP exposure to species, highlighting the associated damage to marine biodiversity related to marine waste. We have applied a multispecies ecosystem approach to analyse the ingestion of anthropogenic particles (AP) in the gastrointestinal tract of 313 individuals (17 fish species and 8 invertebrate species) from pelagic, demersal and benthic habitats in a marine protected area off the Western Mediterranean (Cabrera National Park). We have quantified and characterized the ingestion at several taxonomic levels of fish, sea urchins, sea cucumbers, bivalves, and jellyfish in relation to biotic/abiotic factors based on taxonomic groups, trophic guilds (functional groups) and habitats. AP ingestion occurrence ranged from 26 to 100% with no significant differences among taxonomic groups. The fish within the MPA showed an overall ingestion occurrence ranging from 0 to 100%, the echinoderms from 29 to 100%, the bivalves from 72 to 96% and the jellyfish 36% ingestion. The ecosystem approach applied to evaluate overall AP ingestion within the species reported that for trophic guilds, the omnivorous species ingested the highest amounts of anthropogenic items, while herbivores ingested significantly fewer items than all other trophic guilds. Moreover, no significant differences were found amongst habitats, indicating a homogeneous spatial distribution of APs at all studied habitats. The multispecies approach provided insight into the high APs exposure to species within Cabrera MPA, highlighting the potential harm linked with marine litter that threatens marine biodiversity.

Establishing Marine Protected Areas (MPAs) in international waters is critical for the conservation of marine biodiversity. The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) is a global leader in high seas conservation, having established two international MPAs in Antarctica's Southern Ocean, as part of a commitment to establish a representative system of MPAs for the CAMLR Convention Area. CCAMLR MPAs are adopted by consensus. However, consensus decision-making has slowed the MPA adoption process, and since 2016 the Commission has been unable to agree and implement further MPAs, which has stalled the development of the circumpolar representative system. The key aim of this study was to identify how features of the planning process contribute to outcomes, problems and solutions. We conducted semi-structured interviews with 18 scientists, policymakers, and expert observers from fisheries and environmental non-government organisations involved in CCAMLR MPA planning, to explore their perceptions (experiences, opinions, impressions) of the planning process. Our results identify four key features that are influential across multiple areas of the CCAMLR MPA planning and decision-making process: i) a lack of common understanding; ii) the influence of historical relationships and legacy in subsequent planning processes; iii) inconsistencies between expectations of and requirements for MPA planning; and iv) the degree to which CCAMLR principles and practices, norms, and values are shared. We demonstrate how these four features may help or hinder the effectiveness of the current planning process. We then make suggestions regarding how the planning process could be adapted to capitalise on these features. [ABSTRACT FROM AUTHOR]

The worldwide implementation of Marine Protected Areas (MPAs) has been used as a conservation measure to preserve marine biodiversity. Due to technological limitations, many early designated MPAs often neglected the distribution of marine habitats. Marine remote-sensing techniques development represents an opportunity to reshape and rethink MPA designs. This study focuses on the Vila Franca do Campo MPA (established in 1983) on São Miguel Island, Azores, using advanced acoustic remote-sensing techniques (MBES, SSS). Mapping of approximately 394 ha revealed a 1–3 ratio between rock and sediment habitats within the MPA, while the adjacent unprotected area showed a ratio of less than 1–2, with significant black coral gardens observed below 40 m depth. According to these results and the ecological importance of the organisms detected, we recommend remodeling the MPA. Furthermore, identifying readily accessible black coral communities provides an opportunity for comprehensive assessments of their contribution to marine biodiversity and conservation resources. • Remote sensing tools such as MBES, SSS allow the creation of accurate habitat maps. • Shallower black coral gardens were identified beyond the MPA boundaries. • Habitats discovered are of global conservation concern and suggest MPA restructuring. • Several MPAs have deficient ecological assessments due to lack of ecosystem approach.

Cetacean species are highly mobile, most of them regularly travelling over long distances, thereby presenting complex obstacles to their conservation. Identification of their critical habitats, specifically those parts of a cetacean's range that are essential for day‐to‐day survival and for maintaining a healthy population growth rate, is necessary for their effective protection.This study presents a summary of the data on cetacean sightings during surveys that covered substantial parts of the Russian Far East coastal waters from the Okhotsk Sea to Chukotka in order to determine important areas for particular cetacean species. Sixteen cetacean species were registered during the surveys, and for 12 of them with sufficient numbers of sightings, zones with maximum sighting rates were identified.Only 13% of all cetacean sightings and 22% of sightings of protected species occurred within marine protected areas (MPAs). The highest sighting rates for protected species were concentrated off north‐eastern Sakhalin Island, in the Shantar Area, in Anadyr Gulf, in Kresta Bay and in the waters off eastern Chukotka. The analysis of the distribution patterns of various cetacean species in Russian Far East seas provides a solid base for future conservation planning. Lack of specific MPAs for protection of cetaceans and associated biodiversity hinders marine conservation in Russian Far East seas.The study highlights the specific zones important for various cetacean species and suggests the extension of some existing MPAs and the creation of new MPAs for future spatial habitat protection measures.

Increasing rates of Anthropocene biodiversity extinctions suggest a possible sixth mass extinction event. Conservation planners are seeking effective ways to protect species, hotspots of biodiversity, and dynamic ecosystems to reduce and eventually eliminate the degradation and loss of diversity at the scale of genes, species, and ecosystems. While well-established, adequately enforced protected areas (PAs) increase the likelihood of preserving species and habitats, traditional placement methods are frequently inadequate in protecting biodiversity most at risk. Consequently, the Key Biodiversity Area (KBA) Partnership developed a set of science-based criteria and thresholds that iteratively identify sites where biodiversity is most in need of protection. KBA methodology has been rarely applied in the marine realm, where data are often extremely limited. We tested the feasibility of KBA population metrics in the Greater Caribbean marine region using occurrence and population data and threat statuses for 1669 marine vertebrates. These data identified areas where site-specific conservation measures can effectively protect biodiversity. Using KBA criteria pertaining to threatened and irreplaceable biodiversity, we identified 90 geographically unique potential KBAs, 34 outside and 56 within existing PAs. These provide starting points for local conservation managers to verify that KBA thresholds are met and to delineate site boundaries. Significant data gaps, such as population sizes, life history characteristics, and extent of habitats, prevent the full application of the KBA criteria to data-poor marine species. Increasing the rate and scope of marine sampling programs and digital availability of occurrence datasets will improve identification and delineation of KBAs in the marine environment.

We reviewed 140 papers to assess the ecological effectiveness of South Africa's marine protected areas (MPAs). Evidence was assessed for coverage and representivity, protection of important biodiversity areas, other recognised elements of effectiveness, connectivity, and ecological effects—from the scale of individual MPAs to the MPA network scale. We conducted complementary novel analyses to supplement the review and to objectively determine where and how the MPA network can be improved. Evidence shows that South Africa's MPAs now provide some protection to all ecoregions and 87% of ecosystem types but to less than 50% of assessed species groups. MPAs are generally well-sited, but gaps were revealed on the west coast and in estuaries, the deep sea, and two ecologically and biologically significant areas. Enforcement emerged as a key concern, and many MPAs could be improved through expansion or by increasing no-take areas. The majority of relevant papers recorded beneficial ecological effects, detectable as increases in parameters such as the abundance, biomass, sizes or reproductive output of species. Few papers examined whether ecological benefits translate into adjacent fisheries benefits, but all those that did recorded positive effects. Full protection was more effective than partial protection, with effectiveness most clearly demonstrated for vulnerable target taxa. Further research and monitoring to achieve evaluations of effectiveness are recommended, with greater focus on neglected MPAs and species. Understanding the ecological connectivity between MPAs, an important dimension for climate-change adaptation and hence for the persistence and resilience of South Africa's marine biodiversity, is identified as a key area for future research and inclusion in MPA planning.

Introduction: Little is known about the antipatharians in Costa Rica, only three species are known from the Pacific and the occurrence of coral forests was previously reported only for Isla del Coco. Black coral forests were observed at several sites in the north Pacific of the country, within the Guanacaste Conservation Area (ACG), which are reported and characterized in this study. Objective: To determine the species of black corals present in the ACG Marine Sector and its surroundings, and geographically locate the sites where black coral forests grow. Methods: Visual censuses were made by diving, samples were taken and analyzed in the laboratory for identification. Results: These black coral forests are composed of two species: Myriopathes panamensis and Antipathes galapagensis, these species are described and illustrated. The coral forests were found within and outside ACG marine protected areas. Myriopathes panamensis was found between 15-35 m depth and A. galapagensis at 30-45 m. Associated macrofauna was observed among the branches of M. panamensis, their ecological importance and status have not been determined. Conclusions: The species found did not have morphological variations with those described in other similar regions. Associated fauna was found (mainly the anemone Nemanthus californicus, the bivalve Pteria sterna and the longnose hawkfish Oxycirrhithes typus) and needs to be studied to determine its role on black corals. The importance of the ACG as a marine biodiversity conservation site is emphasized. [ABSTRACT FROM AUTHOR]

Introduction: The marine biodiversity is well known in some areas and for some marine ecosystems of the Pacific coast of Costa Rica. The marine sector of Área de Conservación Guanacaste, in the North Pacific of the country, is a priority area for conservation of marine and coastal biodiversity. Objective: Our aim was to increase the knowledge of marine biodiversity in a conservation priority site in Costa Rica and in poorly or scarcely studied marine ecosystems, such as rocky reefs and Sargassum beds, respectively. Methods: The study was conducted in Bahía Salinas and Golfo de Santa Elena in 2013. In January, four rocky reefs were visited; while in February three rocky reefs and one Sargassum bed were visited. We identified the macroinvertebrates and conspicuous fish species through underwater visual census methods (timed swim and band transects). The mean density of each species was estimated through band transects method. Results: A total of 25 invertebrates and 34 fish species were identified. We found a high number of species of invertebrates (23) and fish species (33) in rocky reefs, but few species on Sargassum beds (eight invertebrates and ten fish species). Species composition differed between marine ecosystems. Conclusions: Our study further evidence the limited knowledge of invertebrates and fish communities in these marine ecosystems in the North Pacific of Costa Rica. Considerably more surveys and field work are required to support management decisions that are backed by sound scientific knowledge. [ABSTRACT FROM AUTHOR]

Marine reserves are a key tool for the conservation of marine biodiversity, yet only ~2.5% of the world's oceans are protected. The integration of marine reserves into connected networks representing all habitats has been encouraged by international agreements, yet the benefits of this design has not been tested empirically. Australia has one of the largest systems of marine reserves, providing a rare opportunity to assess how connectivity influences conservation success. An Australia‐wide dataset was collected using baited remote underwater video systems deployed across a depth range from 0 to 100 m to assess the effectiveness of marine reserves for protecting teleosts subject to commercial and recreational fishing. A meta‐analytical comparison of 73 fished species within 91 marine reserves found that, on average, marine reserves had 28% greater abundance and 53% greater biomass of fished species compared to adjacent areas open to fishing. However, benefits of protection were not observed across all reserves (heterogeneity), so full subsets generalized additive modelling was used to consider factors that influence marine reserve effectiveness, including distance‐based and ecological metrics of connectivity among reserves. Our results suggest that increased connectivity and depth improve the aforementioned marine reserve benefits and that these factors should be considered to optimize such benefits over time. We provide important guidance on factors to consider when implementing marine reserves for the purpose of increasing the abundance and size of fished species, given the expected increase in coverage globally. We show that marine reserves that are highly protected (no‐take) and designed to optimize connectivity, size and depth range can provide an effective conservation strategy for fished species in temperate and tropical waters within an overarching marine biodiversity conservation framework.

Despite significant progress made in Chile, and globally, in establishing marine protected areas (MPAs), the actual contribution to marine biodiversity conservation needs to be revised, to focus on representativeness and the diversity of tools alongside effective implementation, management, and enforcement.This study makes progress in this direction, describing the most recent advances in marine conservation in Chile and analysing the contribution of the different conservation instruments as well as the distribution of designated areas across ecoregions. Furthermore, it examines the potential contribution of alternative area‐based instruments to balance ocean protection. The advances observed in Chile were compared among four South American countries and five leading countries in ocean conservation, analysing protection levels in coastal areas, continental exclusive economic zones, and overseas territories.Data on MPA boundaries and attributes were sourced from the World Database on Protected Areas and complemented the official information on MPAs and territorial user rights for fisheries and for indigenous people in South America.The current level of protection in Chile is among the highest in the world in area coverage and in the proportion of the continental exclusive economic zone assigned to fully protected areas. However, it exhibits the strongest imbalances in the distribution of designated MPAs between coastal and oceanic waters, in comparison with the leading countries and also within South America (Perú, Chile, Argentina, and Uruguay), and among ecoregions.The patterns observed suggest that Chile has advanced, but concentrated, conservation efforts in low‐threat, remote ecoregions. There is an urgent need to progress towards high‐threat ecoregions, which implies balancing the needs of nature and people. The distribution of ancillary conservation instruments can help double the level of protection in threatened coastal areas, filling gaps in marine conservation and creating an opportunity to progress and diversify conservation strategies.

Explorations of the Mediterranean deep sea using remotely operated vehicles have shown that the sea bed hosts rich habitats, supporting high biodiversity. However, there have been only a few studies dealing with the southern part of the basin, leading to limited protection and conservation efforts in this area.This study aimed to explore the sea bed off Linosa Island (Sicily Channel, southern Mediterranean Sea), which is considered a 'sentinel area' for alien species and global environmental changes owing to its geographic position, thus deserving special attention.Remotely operated vehicle surveys, carried out in 2016 and 2017, were analysed to provide the first ecological characterization of benthic assemblages at depths −19 – −384 m around Linosa Island.Communities were dominated by three priority habitats, amounting to 39% of the almost 5 km of the sea floor that was surveyed. These are represented in the euphotic zone by Posidonia oceanica meadows and, at greater depth, by newly discovered dense coral forests and extended rhodolith/maërl beds. Sixteen habitat‐forming species included in the Red List of the International Union for Conservation of Nature (e.g. gorgonians Eunicella cavolini and Paramuricea clavata, and black corals Antipathella subpinnata and Leiopathes glaberrima) were recorded, as well as individuals of Sargassum sp. at −100 m depth.The volcanic island of Linosa represents a small, naturally preserved area, with very limited human pressure, hosting rich marine benthic biodiversity. Given the high species and habitat richness, we recommend its inclusion in the Special Protected Areas of Mediterranean Importance project (United Nations Environment Programme) and suggest a redefinition of the existing marine protected area extension.

Aim: Holistic marine biodiversity conservation refers to ecosystem‐based management through marine conservation planning (MCP), based on mapping habitat protection priority areas. In practice, MCP is frequently hindered by information gaps in biodiversity distributions, particularly on a marine ecoregion scale. Species distribution modelling (SDM) can help to resolve this gap and provide information essential for MCP scenarios. We constructed habitat configurations for three coastal marine megafauna animals using SDM, then based MCP scenarios on the projected habitat configurations and tested the use of marine megafauna animals as surrogates to protect major ecosystems. Location: Gulf of Thailand, Southeast Asia. Methods: A MaxEnt model was used to project likely habitats for Indo‐Pacific humpback dolphins (Sousa chinensis), Irrawaddy dolphins (Orcaella brevirostris) and sea turtles in the Gulf of Thailand. MARXAN software was used to prioritize spatial configurations for habitat protection. The percentage of overlaps between MARXAN delineations and major biodiversity features in the Gulf of Thailand were calculated. Results: Habitat configurations of humpback dolphins, Irrawaddy dolphins and sea turtles were projected throughout the coastal and estuarine waters along the Gulf of Thailand. MCP based on the habitat of three marine megafauna animals highlighted five critical habitats for the protection of major ecosystems in the Gulf of Thailand. Main conclusions: Holistic MCP starts with mapping critical habitats for marine protected area (MPA) networks, balances MPA networks with maritime livelihood activities and alleviates conflicts between MPA management and local livelihood needs. A combination of SDM and MARXAN methods provides a cost‐effective approach to delineate MPA networks. In this approach, surrogate selection and data preparation should consider niches representative of regional ecosystem features and avoid spatial sampling bias. In coastal and estuarine waters, marine megafauna such as coastal cetaceans and sea turtles may serve as efficient surrogates to protect major ecosystems. [ABSTRACT FROM AUTHOR]

The article discusses that the policy of strategic denial in the Islands promoted by the anzus alliance of Australia, New Zealand, and the United States is designed to reinforce Western power in the wider Asia-Pacific region. It mentions that this agenda is supported by external powers like France, India, and Japan, which all have their own regional agendas.

Marine protected area (MPA) planning often relies on scientific principles that help ensure that an area selected for conservation will effectively protect biodiversity. Capturing ecological processes in MPA network planning has received increased attention in recent years. High‐resolution seafloor maps, which show patterns in seafloor bio‐physical characteristics, can support our understanding of ecological processes.In part, owing to a global lack of high‐resolution seafloor maps, studies that aim to integrate seascape spatial pattern and conservation prioritization often focus on shallow biogenic habitats with less attention paid to deeper benthic seascapes (benthoscapes) mapped using acoustic techniques. Acoustic seafloor mapping strategies yield the spatial information required to extend conservation prioritization research into these environments, making incorporating seafloor ecological processes into conservation prioritization increasingly achievable.Here, a new method is proposed and tested that combines benthoscape mapping, landscape ecology metrics and a conservation decision support tool to prioritize areas with structural and potential connectivity value in MPA placement. Using a case study in eastern Canada, benthoscape composition and configuration were quantified using spatial pattern metrics and integrated into Marxan.Results illustrate how large patches of seafloor habitat in close proximity to neighbouring patches can be preferentially selected when benthoscape configuration is considered. The flexibility of the method for including relevant spatial pattern metrics or species‐specific movement data is discussed to illustrate how benthic habitat maps can improve existing conservation planning methods and complement existing and future work to support marine biodiversity conservation.

Mermaids have become increasingly present in popular culture. At the same time as this mermaid renaissance, states have been negotiating a new international legally binding instrument on the sustainable use and conservation of marine biodiversity in areas beyond national jurisdiction. Faced with increased pressures on ocean ecosystems—fisheries depletion, ocean acidification and plastics pollution—urgent action is required to remedy gaps in the current regime. However, although the problems with this regime are well rehearsed—it is fragmented and based a fictionalised account of ocean space that does not accurately reflect the ecological complexities of the seas and there appears to be little appetite for the root and branch changes necessary to remedy these problems. In appealing to the transnational mythology of mermaids, I seek to reinvigorate calls for a more ecologically sensitive narrative of the seas that will better protect marine biodiversity both within and beyond areas of national jurisdiction.

In order to help safeguard biodiversity from global changes, the Conference of the Parties developed a Strategic Plan for Biodiversity for the period 2011-2020 that included a list of twenty specific objectives known as the Aichi Biodiversity Targets. With the end of that timeframe in sight, and despite major advancements in biodiversity conservation, evidence suggests that the majority of the Targets are unlikely to be met. This article is part of a series of perspective pieces from the 4th World Conference on Marine Biodiversity (May 2018, Montréal, Canada) to identify next steps towards successful biodiversity conservation in marine environments. We specifically reviewed holistic environmental assessment studies (HEA) and their contribution to reaching the Targets. Our analysis was based on multiple environmental approaches which can be considered as holistic, and we discuss how HEA can contribute to the Aichi Biodiversity Targets in the near future. We found that only a few HEA articles considered a specific Biodiversity Target in their research, and that Target 11, which focuses on marine protected areas, was the most commonly cited. We propose five research priorities to enhance HEA for marine biodiversity conservation beyond 2020: (i) expand the use of holistic approaches in environmental assessments, (ii) standardize HEA vocabulary, (iii) enhance data collection, sharing and management, (iv) consider ecosystem spatiotemporal variability and (v) integrate ecosystem services in HEA. The consideration of these priorities will promote the value of HEA and will benefit the Strategic Plan for Biodiversity. [ABSTRACT FROM AUTHOR]

Addressing the challenge of protecting biodiversity in the global ocean requires a sound knowledge and understanding of the complex marine environment.Since 2008 the Global Ocean Biodiversity Initiative (GOBI) has been established as a voluntary dedicated group of marine institutions and scientists working to support conservation and protection of marine biodiversity. A focus has been work to support the Convention on Biological Diversity's Ecologically or Biologically Significant Marine Area (EBSA) process. GOBI partners have provided expert interpretation of evidence‐based information and sought to compile and collate available information.An effective and coherent global network of marine protected areas must include bioregional representative replicates of features; once described, EBSAs can help focus attention on where and what kind of protective measures may be needed.GOBI is currently undertaking a 5‐year programme of research funded by the German International Climate Initiative, working to strengthen baselines and contribute new data to the EBSA and other processes. This involves developing detailed biogeographies for the Pacific and Indian Oceans, assessing the movement of migratory species, advancing understanding of biodiversity at vents and seeps, developing a model governance system for the Costa Rica Thermal Dome, and incorporating Important Bird and Biodiversity Areas and Important Marine Mammal Areas.GOBI has taken initiatives to build on the results of the Census of Marine Life and ensure best available marine biodiversity information is considered by states and intergovernmental organizations. GOBI support for ocean governance, including data development and expert consultation, will also contribute to the United Nations Decade of Ocean Science for Sustainable Development (2021–2030). Future challenges include capacity building and new approaches to incorporate traditional knowledge. [ABSTRACT FROM AUTHOR]

• This paper investigates how institutions affect adaptive capacity to climate change in marine protected areas (MPAs). • We compare the adaptive capacities of MPA organizations in centralized and co-managed MPA governance systems. • Adaptive capacity is examined via the model of social capital residing in networks. • Institutional arrangements direct MPA organizations' external relations and how they access information and knowledge underlying adaptive capacity. Marine protected areas (MPAs) remain central to the conservation of marine biodiversity, but enhancing their resilience under climate change require that organizations managing them are able to adapt. Social factors like institutions can affect organizational capacities to adapt to climate change. Yet our knowledge about how different institutional designs for protected areas affect management adaptive capacity is limited. We address this gap by comparing how two models of MPA governance - centralized and collaborative (co-management) - influence the adaptive capacities of public organizations managing MPAs in East Africa. Social network analysis is used to examine external relations of MPA organizations which are interpreted through the lens of social capital theory to explain the acquisition of information and knowledge that support adaptive capacity. We find differences in the ways focal MPA organizations in the centralized and co-managed MPA systems are connected to their external partners. In the centralized system, the focal MPA organization operates in a less connected network rich in opportunities to bridge disconnected groups that can be a source of novel and diverse information. Conversely, the focal MPA organization in the co-managed system operates in a dense network of interconnected organizations that are likely to have similar information, therefore providing redundant information benefits. The composition of partners around focal MPA organizations which determines information quality is not affected by MPA governance context. We conclude that institutional context affects the relational dimensions of adaptive capacity, by giving greater or fewer opportunities for the development of either bridging or bonding social capital.

Marine protected areas (MPAs) serve as a potential defense against marine degradation, meeting the conflicting priorities and needs of multiple actors. Biodiversity, conservation, and ecotourism constitute a triad of sustainability tropes in tropical MPAs that intersect with and reinterpret local histories of marine interaction, subsistence, and commercial extraction. Science is implicated in this production of resource space, with the state and other actors conscripting science to legitimate particular visions of sustainability. A content and discourse analysis of science-based communication instruments about Wakatobi National Park in Indonesia reveals a process of place branding an MPA as unique biological-economic resource space. Legitimation of science privileges scientific knowledge to promote neoliberal development as economic sustainability. Legitimation by science produces an MPA identity of a paradise of marine biodiversity worthy of conservation as ecological sustainability. And, the construction and absence of local human subjects affects their role as constrained agents in resource space. The result is weak social sustainability. [ABSTRACT FROM AUTHOR]

The Katalalixar National Reserve (KNR) lies in an isolated marine protected area of Magellan Sub-Antarctic channels, which represent an important area for marine biodiversity and macroalgal conservation. The present study is the first report of the species Lessonia spicata, "huiro negro", in the Magellan Sub-Antarctic channels. This finding has implications for macroalgal biogeography and conservation concerns in the Chilean coast. In the ecological assessments of the KNR in 2018 we found populations of L. spicata, specifically on rocky shores of Torpedo Island and Castillo Channel. The morphological identification and molecular phylogeny based on nuclear (ITS1) sequences revealed that these populations of Lessonia are within the lineage of L. spicata of central Chile. This report increases the species richness of kelps for the Magellan Sub-Antarctic Channels from two to three confirmed species (L. flavicans, L. searlesiana and L. spicata), and it also extends the southern distribution range of L. spicata. This species has high harvest demand and is moving towards southern Chile; thus, these populations should be considered as essential for macroalgal conservation in high latitudes of South America.

Young men in coastal Tanzania are often blamed for damaging marine habitats by engaging in unsustainable and destructive fishing practices, including dynamite fishing, but their perceptions have not been sufficiently documented. While marine scientists, international environmental NGOs, and activists have called attention to the destructive fishing practices' devastating impacts, insights into the contextual factors that motivate those who engage in dynamite fishing are limited. Additionally, risk perceptions and concerns regarding the environmental impact and dangers of dynamite fishing among the youth are also understudied. This paper provides ethnographic insights into the historical and contextual factors underlying dynamite fishing in rural coastal Mtwara. It draws on ethnographic data gathered through participant observation, focus group discussions and in-depth interviews with residents from two neighboring coastal villages – one located inside a marine protected area (MPA), and another located outside the MPA's boundary. The paper first examines the views of elderly men and women to provide the historical context of dynamite fishing in coastal Mtwara. It then juxtaposes youth perceptions regarding marine conservation and dynamite fishing in the two villages, vis-à-vis ongoing efforts to curb destructive fishing practices and to enhance marine biodiversity and ecotourism in the region. Results of the study reveal that unresolved tensions between the MPA authorities and local fishers surrounding enforcement practices and unfulfilled gear-exchange-related promises, and allegations of poor governance, are important contextual factors in the persistence of dynamite fishing. The paper concludes by articulating possible remedial measures to mitigate the tensions between youth concerns about their livelihoods, and the goals of marine biodiversity conservation as a way forward in preventing dynamite fishing.

Abstract Marine biodiversity has long been known to provide benefits to the community. However, whether biodiversity conservation has contributed to poverty alleviation remained unclear. This paper investigated the relationship between conservation and poverty alleviation in Sagay Marine Reserve. It specifically looked at the perceived poverty alleviation of poor coastal communities in Brgy. Bulanon. The linear relationship between the community's perception and the different factors affecting it were regressed using an ordered logit analysis. Findings revealed that whenever there were presence of conservation training and projects, and additional number of boats, the fishers and non-fishers alike perceived that they were alleviated from poverty. The comparison between the specific household income of fisherfolks and food and poverty thresholds by the Philippine Statistics Authority showed that the latter variable fell short of the provided thresholds. Despite conservation measures, the fishermen remained food-poor and under poverty. Improvement in their economic condition was also hindered by household size, large number of economically inactive dependents, and the absence of a fishing organization. This paper showed that the establishment of marine reserve was successful in terms of biodiversity conservation but lacked the complementary policies to leverage the adjacent communities, thereby not being able to fully ground poverty alleviation along with conservation. Highlights • Marine biodiversity conservation and poverty alleviation are not strongly linked. • Fishing household incomes were below poverty and food thresholds. • Conservation projects positively affected perceived poverty alleviation. • Poverty levels in the marine reserve fishing community go higher as people age. • Economic condition was hindered by the lack of a fishing organization.

Abstract Social perception is key to the success of biodiversity conservation policies. A range of socioeconomic guilds can be affected by marine conservation. Among them, fishers are the ones most likely affected and affecting marine protected areas (MPAs). Here, we assessed the perceptions on the sustainability of a type of multiple-use MPA, Fishing Reserves (FRs), by a broad spectrum of national (n = 16) and local (n = 14) stakeholder organisations pertaining to six socioeconomic sectors via two online surveys in Spain. We compared organisational perception by stakeholder organisations, and specifically by the fishing guild, with official fishing statistics for six FRs between 1998 and 2016 using a Before-After-Impact (BAI) research design. Spanish FRs were regarded as sustainable marine management tools by most marine and coastal stakeholders, with environmental effects perceived to be more positive than social and economic ones, respectively. However, primary sector organisations stated null or negative effect of FR designation on their activities, although official statistics showed a moderate to large increase in a number of professional fishing-related variables, including number of boats and crews, after designation of most FRs. Spatial scale did not affect stakeholder perception of local socioeconomic effects of FRs, although some relevant local socioeconomic variables that were thought to vary most after FR designation differed across scales. Some suggested managerial improvements for increased socioeconomic sustainability of Spanish FRs by the professional fishing guild included: greater stakeholder engagement in FR designation and operation, more flexible fishing regulations and stricter control of recreational fishing. Highlights • Spanish Fishing Reserves (FRs) were considered sustainable marine management tools. • A sustainability gradient was perceived: environmental > social > economic. • Primary sector organisations perceived negative or null effects of FR designation. • Official statistics showed positive socioeconomic values of fishing in most FRs. • Perception of local socioeconomic effects did not differ across spatial scales.

An online atlas of the Coral Triangle region of the Indo-Pacific biogeographic realm was developed. This online atlas consists of the three interlinked parts: (1) Biodiversity Features; (2) Areas of Importance for Biodiversity Conservation; (3) recommended priorities for Marine Protected Area (MPA) Network Expansion (http://www.marine.auckland.ac.nz/CTMAPS). The first map, Biodiversity Features, provides comprehensive data on the region's marine protected areas and biodiversity features, threats, and environmental characteristics. The second provides spatial information on areas of high biodiversity conservation values, while the third map shows priority areas for expanding the current Coral Triangle MPA network. This atlas provides the most comprehensive biodiversity datasets that have been assembled for the region. The datasets were retrieved and generated systematically from various open-access sources. To engage a wider audience and to raise participation in biodiversity conservation, the maps were designed as an interactive and online atlas. This atlas presents representative information to promote a better understanding of the key marine and coastal biodiversity characteristics of the region and enables the application of marine biodiversity informatics to support marine ecosystem-based management in the Coral Triangle region.

Identifying priority areas for biodiversity conservation is particularly challenging in the marine environment due to the open and dynamic nature of the ocean, the paucity of information on species distribution, and the necessary balance between marine biodiversity conservation and essential supporting services such as seafood provision. We used the Patagonian seabird breeding community as a case study to propose an integrated and adaptive method for delimiting key marine areas for conservation. Priority areas were defined through a free decision‐support tool (Marxan) that included projected at‐sea distributions of seabirds (approximately 2,225,000 individuals of 14 species); BirdLife Important Bird and Biodiversity Areas (IBAs) for pelagic bird species; and the economic costs of potential regulations in fishing practices. The proposed reserve network encompassed approximately 300,000 km2 that was largely concentrated in northern and southern inshore and northern and central offshore regions. This reserve network exceeded the minimum threshold of 20% conservation of the abundance of each species proposed by the World Parks Congress. Based on marine currents in the study area, we further identified the 3 primary water masses that may influence areas of conservation priority through water inflow. Our reserve network may benefit from enhanced marine productivity in these highly connected areas, but they may be threatened by human impacts such as marine pollution. Our method of reserve network design is an important advance with respect to the more classical approaches based on criteria defined for one or a few species and may be particularly useful when information on spatial patterns is data deficient. Our approach also accommodates addition of new information on seabird distribution and population dynamics, human activities, and alterations in the marine environment. Article Impact Statement: Seabird conservation areas can be identified based on distribution of oceanographic features, human impacts, and seabirds at sea. [ABSTRACT FROM AUTHOR]

No-take marine reserves can be powerful management tools, but only if they are well designed and effectively managed. We review how ecological guidelines for improving marine reserve design can be adapted based on an area’s unique evolutionary, oceanic, and ecological characteristics in the Gulf of California, Mexico. We provide ecological guidelines to maximize benefits for fisheries management, biodiversity conservation and climate change adaptation. These guidelines include: representing 30% of each major habitat (and multiple examples of each) in marine reserves within each of three biogeographic subregions; protecting critical areas in the life cycle of focal species (spawning and nursery areas) and sites with unique biodiversity; and establishing reserves in areas where local threats can be managed effectively. Given that strong, asymmetric oceanic currents reverse direction twice a year, to maximize connectivity on an ecological time scale, reserves should be spaced less than 50-200 km apart depending on the planktonic larval duration of target species; and reserves should be located upstream of fishing sites, taking the reproductive timing of focal species in consideration. Reserves should be established for the long term, preferably permanently, since full recovery of all fisheries species is likely to take > 25 years. Reserve size should be based on movement patterns of focal species, although marine reserves > 10 km long are likely to protect ~ 80% of fish species. Since climate change will affect species’ geographic range, larval duration, growth, reproduction, abundance, and distribution of key recruitment habitats, these guidelines may require further modifications to maintain ecosystem function in the future.

The Prestige oil spill had numerous negative effects on marine ecosystems, but it also caused a positive effect, as it contributed to the generation of new scientific information that guided to the large marine protected area "Bank of Galicia" lies becoming part of the European Natura 2000 Network. This protected area represents the 10 % of the total marine area of Galicia (NW Spain). Nevertheless, the Convention on Biological Diversity establishes the objective of increasing the total protected area up to 30 %. A discrete choice experiment was conducted to elicit the social preferences for a conservation program of marine biodiversity in Galicia. Among other characteristics such as the expansion of the protected area to the surroundings of Natura 2000 sites, the establishment of new restrictions in the marine protected areas, or the implementation of payments to affected fishermen, the experiment allows to estimate the change in social welfare associated with the surface of large marine protected areas in the NW Spain. Results show that reaching the objective of the Convention on Biological Diversity would imply an increase in well-being, in monetary terms, of 16.4 million of euros. [ABSTRACT FROM AUTHOR]

In 2015, the Government of Canada committed to protecting 5% of marine and coastal areas by 2017, and 10% by 2020. While admirable progress towards this target has been made, less attention has been given to improving the quality of protection afforded to marine areas. Extensive scientific study supports that several factors are critical to the success of Marine Protected Areas (MPAs) for marine biodiversity conservation and management objectives, including no-take areas and prohibitions on extractive and industrial activities. However, the majority of Canada's MPAs allow extractive uses within their boundaries. As Canada works toward international and national commitments to marine protection targets, it is critical to consider the degree of protection afforded by the legal designations used to create these areas. This paper reviews the current inconsistent standards of protection across marine protected areas (MPAs) designated under the Oceans Act , Canada's flagship legislation for marine protection. Recommended amendments to the law include standards of protection that would exclude all extractive industrial activities from MPAs in order to better guide the designation and decision-making processes for marine protection.

Marine protected areas (MPAs) conserve marine biodiversity and ecosystems by limiting or prohibiting resource use in specific areas. Reduced access to a marine resource will invariably impact local communities which reside nearby and utilise those resources. Social dimensions are recognised as crucial to the success of MPAs in meeting environmental goals, however, these dimensions are poorly understood. While much research is focused on developing countries, the majority of recent growth in MPA coverage is occurring in more economically developed settings. This research aims to address this gap by exploring the diversity of social impacts associated with an established MPA on the mid-coast of Western Australia. A range of extractive and non-extractive stakeholders were interviewed to identify the type of impacts experienced and how these are associated with attitudes towards the MPA. The results demonstrate there is a strong association between the nature of the impacts experienced by stakeholders and their attitudes. The social impacts are not distributed uniformly among stakeholders, with some groups of extractive users suffering the majority of the negative impacts and holding highly critical attitudes. The most common adverse impacts affect individual users’ well-being including feelings of fear, stress, uncertainty and inequity, while impacts on fishing activities are limited. Those who reported broader scale community or environmental benefits held largely positive assessments of the MPA. Together these results illustrate the importance of identifying and mitigating the full spectrum of social impacts experienced, as opposed to a narrow focus on the disruption of fishing activities or socio-economic impacts alone.

The South Orkney Islands Southern Shelf (SOISS) Marine Protected Area (MPA) was the first MPA to be designated entirely within the high seas and is managed under the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). To assist with research and monitoring of the MPA, an international expedition (‘SO-AntEco’) was undertaken in the austral summer of 2016 to contribute towards a better understanding of selected benthic habitats within the region. The benthic assemblages of the SOISS MPA region were found to be strongly correlated with the texture of the seafloor, where hard substrates hosted a greater number of individuals, taxa and biomass with a dominance of filter feeding vulnerable marine ecosystem (VME) taxa, and soft sediments were dominated mostly by deposit feeders. Substantial differences in the abundance of VME taxa were found between sampling gears (shallow underwater camera system and Agassiz trawl). We conclude that camera systems may be more suitable for VME assessments, but additional trawling is advisable for collecting all faunal types and for higher taxonomic resolution. The designation of VME locations based purely on large scale geomorphic classification is not advisable, due to small scale variation in substrate and other local physical influences.
