In 2010, the introduction of other effective area‐based conservation measures (OECMs) into international policy caused a paradigm shift in area‐based conservation, which included consideration of areas outside formal protected areas and places where biodiversity conservation may not be a management objective for the site. Despite the importance of this shift for global conservation, conservation science and policy have been slow to engage with the concept of OECMs. As the world moves toward protecting 30% of the Earth by 2030, it is imperative to develop evidence‐based guidance for how to identify effective conservation measures, especially tools to help evaluate and monitor the biodiversity outcomes associated with potential OECMs. To understand the current progress in developing the concept of OECMs, I evaluated the peer‐reviewed literature to consolidate and synthesize current knowledge. I conducted a thematic analysis of papers to identify the types of challenges and opportunities being discussed and lessons from studies evaluating the effectiveness of OECMs. Only 105 studies mentioned OECMs, and those that did rarely move beyond superficial mention of OECMs as part of area‐based conservation. Around one‐half of studies listed potential risks or benefits of OECMs but none provided evidence these issues have materialized. Twenty‐three studies attempted to identify potential OECMs, although specific case studies were rare. The 7 studies that evaluated existing OECMs were highly critical of how they had been implemented to date. Studies that evaluated conservation outcomes were extremely rare, and suggested effectiveness must be judged on a case‐by‐case basis. The current literature not only leaves many gaps in the science required to operationalize the concept of OECMs, but also often raises additional questions that need to be addressed. If these gaps are not filled by robust science, the promised benefits for biodiversity from OECMs may never be realized. [ABSTRACT FROM AUTHOR]

We developed a gap analysis approach to evaluate whether the genetic resources conserved in situ in protected areas are adequate for conifers in western Oregon and Washington (U.S.A.). We developed geographic information system layers that detail the location of protected areas and the distribution and abundance of each tree species (noble fir [Abies procera Rehd.] and Douglas-fir [Pseudotsuga menzeisii Mirb.]). Distribution and abundance were inferred from available spatial data showing modeled potential and actual vegetation. We stratified the distribution of each species into units for genetic analysis using seed and breeding zones and ecoregions. Most strata contained at least 5000 reproductive-age individuals in protected areas, indicating that genetic resources were well protected in situ throughout most of the study region. Strict in situ protection was limited, however, for noble fir in the Willapa Hills of southwestern Washington. An in situ genetic resource gap arguably occurred for Douglas-fir in the southern Puget lowlands, but this gap was filled by extensive ex situ genetic resources from the same region. The gap analysis method was an effective tool for evaluating the genetic resources of forest trees across a large region. [ABSTRACT FROM AUTHOR]

Using radiotelemetry, we discovered that the Three-wattled Bellbird (Procnias tricarunculata ), one of Central America's largest frugivorous birds, has the most complex migratory pattern yet recorded for a tropical species. The annual migration cycle included 2- to 5-month stopovers in four distinct life zones: two middle-elevation and two lowland sites separated by as much as 200 km. We captured and radio-tagged bellbirds during 4 years between July and September in middle-elevation forest fragments of the Pacific slope, 6 km from Monteverde in the Tilaran mountain range of north-central Costa Rica. These habitats, which exist almost exclusively as small, isolated fragments on private farms, are poorly represented (<2%) in Costa Rica's system of protected areas. During September and October, the bellbirds migrated from this site to the northeast into the lowland Atlantic forest of southeastern Nicaragua and northeastern Costa Rica. In Costa Rica these habitats have been heavily fragmented. In Nicaragua they remain intact but are highly threatened. In November and December, the bellbirds migrated from these Atlantic forests to heavily modified, little-protected forests along the Pacific coast of southwestern Costa Rica, where they remained until March. Here, most individuals utilized forest remnants and second growth on private property. In March the Bellbirds moved from the coastal areas to middle-elevation (1000–1800 m) moist forest on the Atlantic slope of the Tilaran mountains sites, where they bred. In June and July, they left the breeding area and moved back across the continental divide of the Tilaran Mountains to return to the middle-elevation Pacific slopes where they had been captured. Our findings demonstrate the complicated ecological integration of geographically dispersed tropical ecosystems and the need for comprehensive conservation strategies that include representation of the full array of regional habitats and a greater emphasis on maintaining connectivity. The bellbird's migratory pattern reveals serious inadequacies in protected-area networks of Costa Rica, a country that is considered to have one of the best systems of national parks and reserves in the Neotropics.

Anthropogenic impacts on biodiversity can lead to biotic homogenization (BH) and biotic differentiation (BD). BH is a process of increasing similarity in community composition (including taxonomic, functional, and phylogenetic components), whereas BD is a process of decreasing similarity over space and time. Here, we conducted a systematic review of BH and BD in plant communities in tropical and subtropical forests to identify trends and knowledge gaps. Our bibliometric search in the Web of Science returned 1989 papers, of which 151 matched our criteria and were included in the analysis. The Neotropical region had the largest number of articles, and Brazil was the most represented country with 92 studies. Regarding the type of change, homogenization was more frequent than differentiation (noted in 69.6% of publications). The taxonomic diversity component was measured more often than functional and phylogenetic diversity components. Most studies (75.6%) assessed homogenization and differentiation based on a single observation in time; as opposed to few studies that monitored plant community over multiple years. Forest fragmentation was cited as the main determinant of homogenization and differentiation processes (57.2% of articles). Our results highlight the importance of evaluating community composition over time and more than taxonomic components (i.e., functional and phylogenetic) to advance understanding of homogenization and differentiation. Both processes were scale dependent and not mutually exclusive. As such, future research should consider differentiation as a potential transition phase to homogenization and that potential differences in both processes may depend on the spatial and temporal scale adopted. Understanding the complexity and causes of homogenization and differentiation is essential for biodiversity conservation in a world increasingly affected by anthropogenic disturbances.

Zoos and aquaria, often regarded as preservation‐cum‐entertainment enterprises, are also actors in the effort to curb the biodiversity crisis: raising awareness, supporting conservation, and conducting research. We assessed trends in zoo and aquaria research topics and study organisms over time worldwide. For the zoos and aquaria registered in the Species360's Zoological Information Management System and the World Association of Zoos and Aquariums, we compiled metadata on their research published in the peer‐reviewed literature indexed in Scopus and carried out a keyword frequency analysis. The production of scientific papers by zoos increased at a much faster rate than the average accrual of scientific papers in the literature. Evolution of research themes ran parallel to that of biological sciences (e.g., development of molecular genetics or increased awareness about conservation). The focus of 48.5% of zoo‐led research was on vertebrates, of which mammal research was 33.7%. Whether zoos are effectively contributing to conservation may still be debatable, but our results highlight their institutional efforts to increase knowledge about the species in their care. Article impact statement: Research led by zoos has exploded over the last decade, particularly research on conservation and genetics. [ABSTRACT FROM AUTHOR]

Abstract: Understanding human perspectives is critical in a range of conservation contexts, for example, in overcoming conflicts or developing projects that are acceptable to relevant stakeholders. The Q methodology is a unique semiquantitative technique used to explore human perspectives. It has been applied for decades in other disciplines and recently gained traction in conservation. This paper helps researchers assess when Q is useful for a given conservation question and what its use involves. To do so, we explained the steps necessary to conduct a Q study, from the research design to the interpretation of results. We provided recommendations to minimize biases in conducting a Q study, which can affect mostly when designing the study and collecting the data. We conducted a structured literature review of 52 studies to examine in what empirical conservation contexts Q has been used. Most studies were subnational or national cases, but some also address multinational or global questions. We found that Q has been applied to 4 broad types of conservation goals: addressing conflict, devising management alternatives, understanding policy acceptability, and critically reflecting on the values that implicitly influence research and practice. Through these applications, researchers found hidden views, understood opinions in depth and discovered points of consensus that facilitated unlocking difficult disagreements. The Q methodology has a clear procedure but is also flexible, allowing researchers explore long‐term views, or views about items other than statements, such as landscape images. We also found some inconsistencies in applying and, mainly, in reporting Q studies, whereby it was not possible to fully understand how the research was conducted or why some atypical research decisions had been taken in some studies. Accordingly, we suggest a reporting checklist. [ABSTRACT FROM AUTHOR]

The search for generalities in ecology has often been thwarted by contingency and ecological complexity that limit the development of predictive rules. We present a set of concepts that we believe succinctly expresses some of the fundamental ideas in conservation biology. (1) Successful conservation management requires explicit goals and objectives. (2) The overall goal of biodiversity management will usually be to maintain or restore biodiversity, not to maximize species richness. (3) A holistic approach is needed to solve conservation problems. (4) Diverse approaches to management can provide diverse environmental conditions and mitigate risk. (5) Using nature's template is important for guiding conservation management, but it is not a panacea. (6) Focusing on causes not symptoms enhances efficacy and efficiency of conservation actions. (7) Every species and ecosystem is unique, to some degree. (8) Threshold responses are important but not ubiquitous. (9) Multiple stressors often exert critical effects on species and ecosystems. (10) Human values are variable and dynamic and significantly shape conservation efforts. We believe most conservation biologists will broadly agree these concepts are important. That said, an important part of the maturation of conservation biology as a discipline is constructive debate about additional or alternative concepts to those we have proposed here. Therefore, we have established a web-based, online process for further discussion of the concepts outlined in this paper and developing additional ones. [ABSTRACT FROM AUTHOR]

Recognition of the need to include economic criteria in the conservation policy decision-making process has encouraged the use of economic-valuation techniques. Nevertheless, whether it is possible to accurately assign economic values to biodiversity and if so what these values really represent is being debated. We reviewed 60 recent papers on economic valuation of biodiversity and carried out a meta-analysis of these studies to determine what factors affect willingness to pay for biodiversity conservation. We analyzed the internal variables of the contingent-valuation method (measure of benefits, vehicle of payment, elicitation format, or timing of payment) and anthropomorphic, anthropocentric and scientific factors. Funding allocation mostly favored the conservation of species with anthropomorphic and anthropocentric characteristics instead of considering scientific factors. We recommend researchers and policy makers contemplate economic valuations of biodiversity carefully, considering the inherent biases of the contingent-valuation method and the anthropomorphic and anthropocentric factors resulting from the public's attitude toward species. Because of the increasing trend of including economic considerations in conservation practices, we suggest that in the future interdisciplinary teams of ecologists, economists, and social scientists collaborate and conduct comparative analyses, such as we have done here. Use of the contingent-valuation method in biodiversity conservation policies can provide useful information about alternative conservation strategies if questionnaires are carefully constructed, respondents are sufficiently informed, and the underlying factors that influence willingness to pay are identified.

The article focuses on the meta-analysis concerning the effect of forest management on biodiversity based from the paper written by Y. Paillet and colleagues. It discusses four major shortcomings of the study that contradicts the result of their analysis such as observational independence, bias on the taxonomic distribution, and exaggerated generalizations of the taxonomic data. It mentions that data based from the studies on saproxylic beetles were used by Paillet and colleagues for the analysis. It also concludes that the use of species richness as biodiversity value can be misleading and that Paillet and colleagues' analysis did not contribute to the understanding of the effect of forest management on biodiversity.

The article focuses on the Cerulean Paradise flycatcher, an endangered species in Sulawesi, Indonesia and the subject of the first cover of the periodical in May 1987. After 20 years, the flycatcher lives on and along with its fellow rarities is getting the attention it deserves. All areas mentioned in the 1987 paper are now known to contain more species than before. However, most of the species are still severely threatened and many are critically endangered. The author hope to encourage conservation action directed at the threatened, endemic freshwater biodiversity of Sulawesi.

The article presents information on the threats to the biodiversity and ecological sustainability of Australasia and the South Pacific. The biological and cultural diversities are in collision with the imposition of Western cultures and values. The region has high extinction rates and conservation is limited by the small population of trained biologists and committed conservationists. Some of the nations in the Pacific Basin got liberated recently liberated from a colonial past and are still learning to accommodate conflicting cultural values within borders drawn with no regard to contrasting cultures or ecosystem boundaries. The Society for Conservation Biology of Australasia has joined hands with Surrey Beatty & Sons, the publisher of the journal "Pacific Conservation Biology," to promote and offer subscriptions to each other's conservation journals. The subsequent increase in the subscription of the journal will lead to a greater diversity of papers and views on conservation being submitted for publication.

The article introduces a series of papers on the relationship between economic growth and biodiversity conservation.
