Abstract The recent extensive loss of biodiversity raises the question of whether organisms will adapt in time to survive the current era of rapid environmental change, and whether today's conservation practices and policies are appropriate. We review the benefits and risks of inter‐ and intraspecific hybridization as a conservation management tool aimed at enhancing adaptive potential and survival, with particular reference to coral reefs. We conclude that hybridization is underutilized and that many of its perceived risks are possibly overstated; the few applications of hybridization in conservation to date have already shown positive outcomes. Moreover, perceptions of potential risk change significantly [...]

Unravelling the secrets of the relationship between coral and the algae living inside it will help prevent coral bleaching, researchers believe. By using genomic data to look for genes that enhance resilience in the algae, researchers hope to help coral adapt to the environmental shifts created by climate change. [...]

Shipwrecks and sunken structures off the North Carolina coast may act as stepping stones for tropical fish searching for favorable habitats at or beyond the edge of their normal geographic range. A study finds these fishes prefer artificial reefs over natural ones and suggests linked networks of these human-made structures could be used to aid the survival of the ecologically and economically important species. [...]

Abstract To conserve marine biodiversity, we must first understand the spatial distribution and status of at‐risk biodiversity. We combined range maps and conservation status for 5,291 marine species to map the global distribution of extinction risk of marine biodiversity. We find that for 83% of the ocean, >25% of assessed species are considered threatened, and 15% of the ocean shows >50% of assessed species threatened when weighting for range‐limited species. By comparing mean extinction risk of marine biodiversity to no‐take marine reserve placement, we identify regions where reserves preferentially afford proactive protection (i.e., preserving low‐risk areas) or reactive protection (i.e., mitigating [...]

When fishermen and women communicate with their fisher rivals, and cooperate over local environmental problems, they can improve the quality and quantity of fish on coral reefs. The study advances a framework that can be applied to other complex environmental problems where environmental conditions depend on the relationships between people and nature. [...]

Abstract Voluntary, permanent land protection is a key conservation process in many countries. Concerns with the effectiveness of such decentralized processes exist due to the potential for (1) selection bias, that is, the protection of parcels whose land cover would have been conserved in the absence of protection, and (2) local spillover effects, that is, protection increasing the likelihood that adjacent parcels lose land cover due to additional conversion. We examine the validity of both concerns using a quasi‐experimental approach and a dataset of 220,187 parcels and 26 years of protection and land‐cover change in Massachusetts. We find that land acquisitions [...]

Abstract Biodiversity conservation requires space where conservation measures are implemented for a desired purpose. Setting land aside for conservation has been widely applied, while novel conservation modes (private–public partnerships, private multipurpose land management) may be fundamental to achieve conservation goals. We perform an economic analysis of the cost development for two conservation options in California, in‐fee and easements, from 1970 to today. We find that in‐fee options have lower costs than easements in the long run. While there are high costs of purchase for in‐fee, ultimately they even‐out or generate profits. Costs of easements continue growing exponentially overtaking costs of purchase. [...]
