Abstract Policy makers are increasingly encouraging farmers to protect or enhance habitat on their farms for wildlife conservation. However, a lack of knowledge of farmers' opinions toward wildlife can lead to poor integration of conservation measures. We surveyed farmers to assess their perceptions of ecosystem services and disservices from perching birds, raptors, and bats – three taxa commonly targeted by conservation measures. The majority of farmers thought that perching birds and bats were beneficial for insect pest control and that raptors were beneficial for vertebrate pest control; however, fruit farmers viewed perching birds more negatively than did farmers growing other crops.

Abstract If efforts to conserve endangered species lack long-term visions and neglect the human dimensions, conservation success will be questionable. Exclusion of stakeholders in decisions can lead to mistrust and polarization of groups. The story of the vaquita marina (Phocoena sinus) in the Upper Gulf of California provides a unique opportunity to discuss this paradigm. A proposed gear-switch in the regional fisheries addresses the bycatch issue that threatens the vaquita but neglects livelihoods, the traditions and heritage of the community, and the ecological integrity of the area, and it increases dependence on fishing subsidies. We estimate that it will cost an [...]

Dead zones affect dozens of coral reefs around the world and threaten hundreds more according to a new study. Watching a massive coral reef die-off on the Caribbean coast of Panama, they suspected it was caused by a dead zone -- a low-oxygen area that snuffs out marine life -- rather than by ocean warming or acidification. [...]

Abstract The exploitation status of marine fisheries stocks worldwide is of critical importance for food security, ecosystem conservation, and fishery sustainability. Applying a suite of data-limited methods to global catch data, combined through an ensemble modeling approach, we provide quantitative estimates of exploitation status for 785 fish stocks. Fifty six percent (439 stocks) are below BMSY and of these, 261 are estimated to be below 80% of the BMSY level. While the 178 stocks above 80% of BMSY are conventionally considered “fully exploited”, stocks staying at this level for many years, forego substantial yield. Our results enable managers to consider more [...]

Abstract The IUCN Red List of Threatened Species provides assessments of extinction risk for over 80,000 species. It has become an important tool for conservation and for informing natural resource policy and management more broadly. Over the last 10–15 years, the role of the Red List in business decision-making has become increasingly significant. We describe the key business uses of the Red List and their benefits to conservation, focusing on industrial-scale development and supply chains. The Red List is used by business throughout the process of planning and implementing projects, in order to understand and manage potential impacts on biodiversity. It [...]

Abstract How should we meet the demand for wood while minimizing climate and biodiversity impacts? We address this question for tropical forest landscapes designated for timber production. We model carbon and biodiversity outcomes for four archetypal timber production systems that all deliver the same volume of timber but vary in their spatial extent and harvest intensity. We include impacts of variable deforestation risk (secure land tenure or not) and alternative harvesting practices (certified reduced-impact logging methods or not). We find that low-intensity selective logging offers both the best and the worst overall outcomes per unit wood produced, depending on whether certified reduced-impact [...]

Coral researchers are remobilizing to conduct aerial and underwater surveys along the Great Barrier Reef and elsewhere in Australia as coral bleaching reappears for the second year in a row. The decision coincides with the release today of a study in the journal Nature warning the Reef's resilience is rapidly waning. [...]

Monitoring a newly discovered group of genes in coral could predict when they are under stress and might bleach. The approach could improve conservation strategies for at-risk coral reefs, say scientists. [...]

Abstract From birds to bacteria, airborne organisms face substantial anthropogenic impacts. The airspace provides essential habitat for thousands of species, some of which spend most of their lives airborne. Despite recent calls to protect the airspace, it continues to be treated as secondary to terrestrial and aquatic habitats in policy and research. Aeroconservation integrates recent advances in aeroecology and habitat connectivity, and recognizes aerial habitats and threats as analogous to their terrestrial and aquatic counterparts. Aerial habitats are poorly represented in the ecological literature and are largely absent from environmental policy, hindering protection of aerial biodiversity. Here, we provide a framework [...]

Abstract The terrestrial protected areas of Antarctica are generally small, unrepresentative of the continent's biodiversity, and at risk from a range of pressures. While some consider the whole Antarctic region as a protected area, we demonstrate that the evidence does not support this view. The Protocol on Environmental Protection to the Antarctic Treaty recognizes that a systematic environmental-geographical framework provides a quantitative approach to inform expansion of the current Antarctic Specially Protected Area (ASPA) network. We review the progress thus far and challenges facing the establishment of protected areas in terrestrial Antarctica when adopting best practice approaches, an assessment that is [...]

Abstract Wildlife trade is currently the most important and increasing source of vertebrate invasive species. However, exhaustive analyses of potential side effects of trade regulations on this pathway of introduction are lacking. We addressed this by combining environmental niche models and global trade data on parrots (Psittaciformes), one of the most widely traded and worldwide invasive taxa. We used the wild bird trade bans of USA (1992) and Europe (2005) as case-studies. Results showed that regional bans can generate geographic redirections in trade, with important consequences on worldwide invasion risk. While the amount of parrots traded internationally remained largely constant, changes [...]

Abstract The giant panda (Ailuropoda melanoleuca) is no longer Endangered on the International Union for the Conservation of Nature's (IUCN) storied Red List. The decision to downlist the panda to Vulnerable has its foundation in a systematic assessment of population parameters as determined by China State Forestry Administration's circa decadal national survey and other scientific outputs, compared to standardized criteria used by IUCN to determine the status of all species. This decision has not been without controversy and disagreement, perhaps reflecting disparities between how people view the term “Endangered” and the criteria established by the IUCN. Here, we explore the architecture [...]

Abstract Artisanal fisheries are generally assumed to generate a lower fishing effort in comparison to the industrial sector. This study aims to comparing catch, fishing effort, and catch-per-unit-of-effort (CPUE) for each sector, using kWdays as a metric for fishing effort, and kg/kWdays for CPUE. The study, which covers West Africa (1950-2010), finds that the artisanal sector spends 4.7•109 kWdays/year vs. 1.3•109kWdays/year by the industrial sector, due to increasing numbers and size of artisanal boats, which in Senegal and Ghana can exceed that of (smaller) industrial vessels. The artisanal total fishing effort increased by 10-fold between 1950 and 2010, in contrast to [...]
