Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

Coexistence and habitat restoration planning for the reintroduction of Spix's macaw
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Spix's macaw (Cyanopsitta spixii) is one of the world's most endangered species. Native to the Caatinga of northeastern Brazil—a region marked by significant socioeconomic vulnerability—the species was considered extinct in the wild in 2000. A reintroduction project, however, returned it to its natural habitat in 2022. The long‐term success of

Conservation Biology, Volume 39, Issue 6, December 2025.Abstract As the coverage of area‐based conservation increases across the globe, it is critical to improve understanding of the social and ecological outcomes of such measures and the pathways to their outcomes. A social–ecological systems approach to monitoring and evaluation is increasingly advocated; yet, applications remain scarce.
