Using the capabilities approach to achieve people‐centered conservation
Conservation Biology, EarlyView.Abstract Top‐down interventions carried out by state and nonstate institutions to conserve biodiversity and improve the lives of forest‐proximate people (FPP) in the Global South tend to reflect economistic understandings of human well‐being. More progressive and people‐centered conservation projects are guided by normative visions of how the world ...

Genomics‐informed management of ex situ populations
Conservation Biology, EarlyView.Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

Optimizing biodiversity offsetting for habitat succession and colonization dynamics
Conservation Biology, EarlyView.Abstract Biodiversity offsetting aims to compensate for ecological losses from development through conservation and restoration. However, its long‐term outcomes under repeated impact–offset cycles remain uncertain. Using a conceptual forest succession model, we evaluated how offset outcomes are affected by interactions among compensation scale ...

Synthesis of Pollinator‐Friendly Management in European Protected Areas
Conservation Biology, EarlyView.Effectiveness of pollinator‐friendly management in European protected areas. Abstract Pollinators are important to humans and nature due to their role in ecosystem functioning and services. Research on the effects of pollinator management in protected areas is insufficient compared with that on farmlands and urban areas, potentially hindering ...
