Abstract

The surmullet Mullus surmuletus Linnaeus, 1758 is one of the main target and high valuespecies for small coastal fisheries in the North-Western Mediterranean. Morphometric andreproduction indices of surmullet were determined in fisheries regulated and non-regulatedzones neighbouring the Port-Cros National Park (South-Eastern France) in autumn 2019 andspring 2020. Total length of individuals ranged between 12 and 32 cm, with a mode (?)between 17 and 23 cm. Significantly larger individuals were measured in the regulated fishingzones than in non-regulated ones, and in autumn rather than in spring. Females dominated inall zones and seasons, particularly in size classes > 24 cm in spring. Higher gonado-somaticindex and more advanced gonadal development stages were observed in both sexes in springthan in autumn. Higher percentages of individuals with mature gonads and high gonado-somatic index were found in the fisheries regulated zone, engendering a higher reproductivepotential. These results highlighted the importance of fisheries management with regard to thelife-history traits of targeted fish species., Le rouget de roche Mullus surmuletus est l'une des principales espèces cibles etcommerciales des pêcheries côtières artisanales de la Méditerranée nord-occidentale. Lamorphométrie et les indices de reproduction du rouget ont été déterminés dans les zones depêche réglementées et non réglementées autour du Parc National de Port-Cros (Sud-Est de laFrance) à l'automne 2019 et au printemps 2020. La longueur totale des individus variait entre12 et 32 cm, avec un mode entre 17 et 23 cm. Des individus significativement plus grands ontété mesurés dans la zone de pêche réglementée comparativement aux zones non réglementées,et en automne par rapport au printemps. Les femelles dominaient dans toutes les zones etsaisons, en particulier dans les classes de taille > 24 cm au printemps. Un indice gonado-somatique plus élevé et des stades de développement gonadiques plus avancés au printempsqu’en automne ont été observés chez les deux sexes. Des pourcentages plus élevés d'individusavec des gonades matures et un indice gonado-somatique élevé ont été trouvés dans la zone depêche réglementée, induisant un plus fort potentiel reproducteur. Ces résultats mettent enévidence l'importance de la gestion des pêches sur les traits d'histoire de vie des espèces depoissons ciblés.

Abstract

International audience; Deep-sea environments in the Mediterranean Sea have been widely degraded over the past decades and thus there is an urgent need to implement protection measures. Within European Union's Mediterranean waters vast extensions of the deep-sea ecologically relevant ecosystems have been protected by integrating them to the Natura 2000 network. Inside the French Exclusive Economic Zone, this network is currently expanding to off-shore areas, beyond 12 nautical miles. In this study, we characterized megabenthic biodiversity on target features located inside a designed site of the south west Corsican margin, particularly on a volcanic promontory on the south flank of the Ajaccio submarine canyon and a wall of the Valinco Canyon, between 1690 and 2250 m depth. By means of a fine scale three-dimensional photogrammetric analysis, four megabenthic assemblages segregated by substrate were identified. Hard substrate assemblages were characterized by the presence of sponges, polychaetes, gastropods and the squat lobster Munida tenuimana while soft sediment assemblages were characterized by the elpidiid holothurian Penilpidia ludwigi and an unidentified sabellid. Highest densities were registered on serpulid thanatocoenoses, which hosted widespread patches of an unidentified encrusting sponge. Lebensspuren had a diverse origin likely deriving from the activity of epibenthic, infaunal and bathypelagic organisms. In general, litter was not abundant at these offshore sites: in the Valinco site, it had both a marine and land-based origin while at the even more offshore Ajaccio site, it was mainly marine based. More extensive surveys would be advisable to confirm this trend. This study provides new insight on the ecology and diversity of Mediterranean deep-sea environments in the 2000 m bathymetric zone, highlighting the enduring knowledge gap surrounding orographically complex deep-sea escarpments in the basin.

Abstract

The ctenophore Mnemiopsis leidyi A. Agassiz, 1865 originates from estuaries and coastal waters along Atlantic coastlines from the Chesapeake Bay, USA, to Argentina. Through ballast waters, the species has spread the past 30 years over Eurasia. On the French Mediterranean coastlines, Mnemiopsis leidyi was first formally identified in the Berre Lagoon in 2005 and has been episodically present in other Mediterranean lagoons as Bages-Sigean, Vaccares, and Estomac. Since 2010–2011 no update of the distribution of Mnemiopsis leidyi has been made. Since 2019, many records of Mnemiopsis leidyi have been reported in other French Mediterranean lagoons along the coast of the Gulf of Lion. In this context, a field survey on the French Mediterranean coast was conducted in July 2020 to measure the expansion of the Mnemiopsis population in coastal lagoons which are potential refuge habitats for this species. Mnemiopsis leidyi was present in 8 different areas: Or, Perols, Vic, Ingril, Rhone-Sete Channel, Bages-Sigean, and Salses-Leucate. We were able to quantify for the first time the abundance and size structure of Mnemiopsis in the lagoons of Or, Perols, Vic, Ingril, Rhone-Sete Channel, and Salses-Leucate. A decrease in the abundance of Mnemiopsis leidyi was observed from 1 ind m−3 (Ingril Lagoon) to 28 ind m−3 (Grec Lagoon) and 42 ind m−3 (Rhone-Sete Channel) between the North and the South along the Rhone-Sete Channel in parallel to the increase of salinity (from 20 to 41). The abundances measured in Bages-Sigean and Salses-Leucate lagoons were similar: 6 ind m−3 and 7 ind m−3 respectively.

Abstract

Este artículo contiene 18 páginas, 4 figuras., Good datasets of geo-referenced records of alien species are a prerequisite for assessing the spatio-temporal dynamics of biological invasions, their invasive potential, and the magnitude of their impacts. However, with the exception of first records on a country level or wider regions, observations of species presence tend to remain unpublished, buried in scattered repositories or in the personal databases of experts. Through an initiative to collect, harmonize and make such unpublished data for marine alien and cryptogenic species in the Mediterranean Sea available, a large dataset comprising 5376 records was created. It includes records of 239 alien or cryptogenic taxa (192 Animalia, 24 Plantae, 23 Chromista) from 19 countries surrounding the Mediterranean Sea. In terms of records, the most reported Phyla in descending order were Chordata, Mollusca, Chlorophyta, Arthropoda, and Rhodophyta. The most recorded species was Caulerpa cylindracea, followed by Siganus luridus, Magallana sp. (cf. gigas or angulata) and Pterois miles. The dataset includes records from 1972 to 2020, with the highest number of records observed in 2018. Among the records of the dataset, Dictyota acutiloba is a first record for the Mediterranean Sea. Nine first country records are also included: the alga Caulerpa taxifolia var. distichophylla, the cube boxfish Ostracion cubicus, and the cleaner shrimp Urocaridella pulchella from Israel; the sponge Paraleucilla magna from Libya and Slovenia; the lumpfish Cyclopterus lumpus from Cyprus; the bryozoan Celleporaria vermiformis and the polychaetes Prionospio depauperata and Notomastus aberans from Malta., The publication of this article is supported by the Open Access Publishing Fund of the International Association for Open Knowledge on Invasive Alien Species (INVASIVESNET; www.invasivesnet.org).

Abstract

International audience; reefs (ARs) are deployed worldwide as they are expected to support fisheries management. 22 While the underlying mechanisms remain widely debated, production was recently determined as 23 the most probable cause of increases in fish biomass. Changes in fish biomass in a temperate AR 24 system were investigated from December 2008 to November 2015 by considering seven distinct 25 functional groups, and isotopic functional indices were used to identify how these changes may have 26 affected organic matter (OM) fluxes. Contrasting patterns of change were observed between 27 functional trophic groups, highlighting that combining the biomass of all species present in a 28 community is inappropriate for assessing AR-induced effects. Benthic sedentary species 29 predominated (>75% of the total biomass) through massive production, with a 68-fold increase in 30 mean biomass over the study period. Mobile species tended to vary seasonally, suggesting only a 31 slight influence of AR. Zooplanktivores biomass decreased over the 6-year period, as a possible result 32 of changes in environmental conditions. Isotopic indices helped to reveal both the community 33 maturation and the importance of local OM sources not only in supporting fish biomass production 34 but also in attracting pelagic species. Our results corroborate that production and attraction are two 35 extremes of a range of contrasting patterns and highlight the importance of considering the specific 36 responses of functional components of fish communities to accurately describe changes in AR 37 functioning. Functional attributes such as trophic traits, habitat use and dispersal abilities must not 38 be overlooked as they modulate fish species responses to the deployment of man-made rocky 39 substrates.

Abstract

International audience; Marine cave communities have been a continued source of ecological surprises, among other things because of their close ecological and evolutionary ties with the deep sea. The discovery of cladorhizid sponges, the deepest occurring poriferan family, in shallow Mediterranean caves in the 1990s was one such surprise, leading to the generally accepted hypothesis that the whole family was carnivorous, an unprecedented feeding mode for sponges. The recent observation of the cave species Asbestopluma hypogea in the Mediterranean bathyal, confirmed the view that some shallow caves can occasionally shelter otherwise deep-dwelling species. Here we present new distribution data of A.hypogea, from deep Mediterranean locations, and for the first time from Atlantic locations. Among the new Atlantic records, the most surprising ones are located in three different geographic areas (Ria de Arousa, Groix Island and Cherbourg) of the NW European coasts, from the Iberian Peninsula to the English Channel, where A.hypogea reaches SCUBA depths (5-50m), while not sheltered in marine caves. The carnivorous sponge however reaches its shallowest occurrence (5m), in a small cave at Groix Island. The ecological significance of these discoveries, particularly the very patchy distribution and peculiar dynamics, are noteworthy, and the shallow occurrence of A.hypogea, together with other deep-water or uncommon species, constitute unique assemblages that must be considered in conservation plans.

Abstract

International audience; In the context of growing anthropogenic disturbances that deeply alter marine coastal ecosystems, various management tools are used to protect biodiversity, such as fishing gear limitations, fishing quotas, protected areas or the creation of artificial reefs (ARs). In contrast to the other management tools, ARs require a modification of natural habitats. We used underwater visual censuses to investigate the effect of habitat modification on the structure of fish communities by comparing a natural reef (NR) to ARs with different habitat complexity. Different fish assemblage descriptors were used to assess species- and functional- and community-level aspects of the assemblages. ARs were rapidly colonized by adult fishes and presented community compositions different from that of the NR. Fish densities and functional richness were higher in the ARs than in the NR. Small isolated artificial structures, such as culverts and box-culverts, had different fish community compositions than more extended and complex structures, demonstrating the effect of structural habitat complexity on fish assemblages. Fish density was higher in small structures, most likely due to habitat isolation and patchiness. This study indicates that ARs which are located along sandy coastal areas with few rocky habitats and under high river nutrient influence, are a suitable habitat for rocky coastal fish communities. Nevertheless, due to higher habitat complexity and lower fishing pressure on ARs, fish communities of an AR functionally differ from those of a NR. Further research is necessary to understand how these differences act on the properties of the ecosystem as well as on local fisheries.

Abstract

International audience; Les communautés de macrophytes (algues et phanérogames), dont certaines espèces sont protégées, constituent un des indicateurs clés de l'état écologique des lagunes, tel que défini par la Directive Européenne Cadre sur l'Eau (DCE). Par ailleurs, la restauration de ces communautés de macrophytes, et des herbiers de Zostera en particulier, est l'un des objectifs principaux de la réhabilitation de l'Etang de Berre (Bouches-du-Rhône) portée par le Gipreb (Groupement d'intérêt public pour la réhabilitation de l'Etang de Berre). C'est pourquoi celui-ci met en oeuvre, depuis 1996, le suivi des principales espèces de macrophytes encore présentes dans l'étang. La densité de chaque espèce ou groupe d'espèces a été évaluée visuellement par des plongeurs le long de 31 transects (composés chacun de 20 segments de même longueur) répartis sur le pourtour de l'étang, et ce pendant 11 années. L'évaluation consiste en un codage en 6 modalités du taux de couverture du fonds par l'espèce. L'état annuel de la population de chaque espèce est finalement décrit par un tableau de type 6x20, croisant la densité avec la position : deux variables ordinales. La suite des 11 tableaux sera donc ici décrite via l'Analyse des Correspondances Ordinales de Beh (1997). Les résultats obtenus seront comparés avec ceux de l'AFC. Bibliographie : E. J.

Abstract

15 pages, 12 figures, 5 tables.-- Issue title: Special Issue on European marine protected areas as tools for fisheries management and conservation, Presentation with same title (18 slides) by Frédérique Alban, Nicolas Roncin and Jean Boncoeur at Les Journées AMURE, Brest, May 27-28, 2009, available at: http://www.umr-amure.fr/conf/journees_amure/2009/empafish.pdf, This paper addresses the problem of measuring the local economic impact of marine protected areas (MPAs). It relies on a broad socio-economic field survey covering 12 case studies in southern Europe, and focusing on two major uses of MPA ecosystem services: fishing and scuba-diving. The impact of these uses on the local economic system is expressed in terms of incomes and jobs, and the methodology relies on a distinction between users transforming ecosystem services into commodities, and users consuming ecosystem services for recreational purposes. Assessment results show a variety of situations, from MPAs where commercial fishing is the major economic stake, to MPAs where recreational activities have a dominant economic role. However, available information concerning the number of recreational users and visitors, on one side, and the number and characteristics of commercial fishing boats, on the other side, suggest that the second situation is more representative of the area under study than the former one. Due to the lack of baseline, the question of sorting out the “reserve effect” from the “site effect” is addressed with the help of survey results concerning perceptions and attitudes of users. As regards divers and diving operators, answers to the survey suggest that the reserve effect plays an important role in the attractiveness of the area. Results are not so clear in the case of fishers, an ambiguity reflecting the uncertainty of the spill-over effects expected from marine reserves on fishing grounds, The research presented in this paper was developed as a part of the research project "European Marine Protected Areas as Tools for fisheries Management and Conservation" (EMPAFISH SSP8-006539) supported by the Commission of the European Communities within the 6th Framework Programme

Abstract

To assess the dynamics of seagrass beds, it is necessary to be able to compare their present day and former distribution patterns. In most cases, ancient data are available in the form of maps whose reliability must be estimated before comparison. In the study area (near Marseilles, France), a series of maps of the seagrass Posidonia oceanica beds spanning more than one century (dating from 1883, 1897, 1958, 1975, 1979, 1991 and 2000, respectively) are available. In addition, a new map was established, using aerial photography (shallow areas), side scan sonar (deeper areas) and data validation by ground truth. In order to help assess the value of the ancient maps, a Reliability Index (RI) is proposed. The RI, rated from 0 to 50, weighs three parameters: (i) the initial scale of the map (source map) and the working scale (target map); (ii) the method of data acquisition (e.g. dredges, grabs, aerial photography, side scan sonar, scuba diving); and (iii) the method of data georeferencing. Dramatic differences in the distribution of seagrass beds are apparent between the eight maps. In view of the biological features of P. oceanica (e.g. slow rate of change of the meadow limits under natural conditions and the persistence of rhizomes after its death), it is possible that some of these differences may not reflect change over time but may be due to errors in the ancient maps. In contrast, other differences are plausible and validated by field data, e.g. the regression of the lower limit of the meadow. It was thus possible to compare the calculated RI for each map and the plausibility of observed differences as a basis for calibrating the RI. 2003 Elsevier Ltd. All rights reserved.

Abstract

A significant challenge in the integration of ecosystem services into decision-making processes lies in effectively capturing the dynamics of marine socio-ecological systems, including their evolutionary pathways, equilibrium states, and tipping points. This paper explores the evolutionary trajectories of a vital marine ecosystem endemic to the Mediterranean Sea: the Posidonia oceanica seagrass meadows, in response to various drivers of change. A state-and-transition model is employed to assess the ecosystem services provided by P. oceanica across different states defined by selected transitions, such as overfishing, fragmentation, pollution, and invasion by non-native species. To apply this model, scientific expertise is combined with field data generated using the Ecosystem-Based Quality Index to evaluate the conservation status of P. oceanica. This integrated approach allows for the representation of the ecosystem services offered by the meadows across different states, leveraging ecological data. The findings highlight the disproportionate impact on provisioning services, particularly sea urchins and commercial fish production, which suffer the most under various stressors. Notably, when these services decline to critical levels, the meadows cease to provide significant benefits. Finally, a synthesized representation is presented, merging ecological insights with monitoring data, offering a framework that is more accessible to stakeholders and decision-makers., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Abstract

Phylogenetic relationships and the timing of evolutionary events are essential for understanding evolution on longer time scales. Cheilostome bryozoans are a group of ubiquitous, species-rich, marine colonial organisms with an excellent fossil record but lack phylogenetic relationships inferred from molecular data. We present genome-skimmed data for 395 cheilostomes and combine these with 315 published sequences to infer relationships and the timing of key events among c. 500 cheilostome species. We find that named cheilostome genera and species are phylogenetically coherent, rendering fossil or contemporary specimens readily delimited using only skeletal morphology. Our phylogeny shows that parental care in the form of brooding evolved several times independently but was never lost in cheilostomes. Our fossil calibration, robust to varied assumptions, indicates that the cheilostome lineage and parental care therein could have Paleozoic origins, much older than the first known fossil record of cheilostomes in the Late Jurassic.

Abstract

Coastal zones are ecosystems of high economic value but exposed to numerous disturbances, while they represent nurseries for many fish species, raising the issue of the preservation of their functions and services. In this context, the juvenile fish assemblages of all types of habitats present in shallow coastal zones were studied on the south-east coast of France using underwater visual censuses in warm (June-July 2014) and cold (April 2015) periods. A total of fourteen habitat types were characterized, which could be grouped into three broad categories, rocky substrates (natural and artificial), sedimentary bottoms with all levels of granulometry, and seagrass beds including Cymodocea nodosa and Posidonia oceanica meadows; the ecotones or interfaces between the three broad habitat categories were individualized as particular habitat types. The abiotic and biotic descriptors of the 14 habitat types individualized did not vary with time, except for a higher cover percentage and canopy height of macrophytes in the warm period, which increased the three-dimensional structure of some habitats. The taxonomic composition and density of juvenile fish assemblages were analyzed using both multivariate and univariate descriptors, after grouping the 57 fish species recorded into 41 well-individualized taxa. Juvenile fishes were recorded in all habitat types, with higher mean species richness and abundance during the warm than the cold period. The richest habitats in terms of both fish species richness and abundance were the natural rocky substrates and the interfaces between Posidonia beds and the other habitats. Although juvenile fish assemblage composition differed among habitat types and between periods, the most abundant fish species were Atherina sp., Sarpa salpa, Gobiidae, Symphodus spp., Pagellus spp. and several Diplodus species, which colonized 7 up to 14 different habitat types (depending on taxa) during their juvenile life. Most species settled in one or a few specific habitats but rapidly colonized adjacent habitats when growing. This study provided evidence of the role of all types of shallow coastal habitats as fish nurseries and their varying pattern of occupation in space and time by the different juvenile stages. It highlighted the importance of the mosaic of habitats and interfaces for the complete development of all juvenile life stages of fishes, and for the preservation of a high diversity of coastal fish assemblages and fisheries resources in the Mediterranean Sea., (© 2021.

Abstract

The distribution and the vitality of the P. oceanica meadow were monitored in the western Mediterranean at 15 sites along the coasts of Corsica (1000 km of coastline) using two monitoring systems, the Posidonia Monitoring Network and SeagrassNet, between 2004 and 2013. While the vitality of the meadow is satisfactory overall, due to the low impact of human pressure along these coasts, patterns of change over time show a slight degradation of the main descriptors of the meadow. The meadow's vitality index had declined on average by 8.6%, the BiPo index by 9.8%, and there was a regression of the lower limit at six sites. While this pattern of change may reflect local alterations in the environment (increase or decline in human pressure), the regressive dynamic of the meadow observed at the lower limit at several reference sites (e.g., Marine Protected Areas, sites distant from sources of human impact) is more worrying. Two hypotheses might explain the regression observed: (i) the rise in mean sea level during the study period, which may have resulted in a significant regression in sectors where the slope is relatively slight, and (ii) the North Atlantic Oscillation (NAO), which declined from 2002 to reach very low values in 2010., (Copyright © 2015 Académie des sciences.

Abstract

Biotic indices, which reflect the quality of the environment, are widely used in the marine realm. Sometimes, key species or ecosystem engineers are selected for this purpose. This is the case of the Mediterranean seagrass Posidonia oceanica, widely used as a biological quality element in the context of the European Union Water Framework Directive (WFD). The good quality of a water body and the apparent health of a species, whether or not an ecosystem engineer such as P. oceanica, is not always indicative of the good structure and functioning of the whole ecosystem. A key point of the recent Marine Strategy Framework Directive (MSFD) is the ecosystem-based approach. Here, on the basis of a simplified conceptual model of the P. oceanica ecosystem, we have proposed an ecosystem-based index of the quality of its functioning, compliant with the MSFD requirements. This index (EBQI) is based upon a set of representative functional compartments, the weighting of these compartments and the assessment of the quality of each compartment by comparison of a supposed baseline. The index well discriminated 17 sites in the north-western Mediterranean (French Riviera, Provence, Corsica, Catalonia and Balearic Islands) covering a wide range of human pressure levels. The strong points of the EBQI are that it is easy to implement, non-destructive, relatively robust, according to the selection of the compartments and to their weighting, and associated with confidence indices that indicate possible weakness and biases and therefore the need for further field data acquisition.

Abstract

Groupers species are extremely vulnerable to overfishing and many species are threatened worldwide. In recent decades, Mediterranean groupers experienced dramatic population declines. Marine protected areas (MPAs) can protect populations inside their boundaries and provide individuals to adjacent fishing areas through the process of spillover and larval export. This study aims to evaluate the effectiveness of six marine reserves in the Western Mediterranean Sea to protect the populations of three species of grouper, Epinephelus marginatus, Epinephelus costae and Mycteroperca rubra, and to understand in which circumstances MPAs are able to export biomass to neighbouring areas. All the studied MPAs, except one where no grouper was observed, were able to maintain high abundance, biomass and mean weight of groupers. Size classes were more evenly distributed inside than outside MPAs. In two reserves, biomass gradients could be detected through the boundaries of the reserve as an indication of spillover. In some cases, habitat structure appeared to exert a great influence on grouper abundance, biomass and mean individual weight, influencing the gradient shape. Because groupers are generally sedentary animals with a small home range, we suggest that biomass gradients could only occur where groupers attain sufficient abundance inside MPA limits, indicating a strongly density-dependent process.
