Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

People and Nature, Volume 8, Issue 6, Page 1943-1956, June 2026.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Contrasting mechanisms driving the northward expansion of African raptors in Europe

Journal of Zoology, Volume 329, Issue 2, Page 145-155, June 2026.
Recent climate warming and landscape changes are enabling African raptors to reach Europe through contrasting mechanisms. Using species distribution models, we show that the Atlas Long‐legged Buzzard expands northward following climatic suitability, whereas African vultures reach Europe despite low climatic favourability through socially mediated ...

Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

Conservation Biology, Volume 40, Issue 2, April 2026.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

A multiscale seasonal examination of the risk of harm to seabirds from vessels based on co‐occurrence in Alaskan waters

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Alaska's seascape supports globally significant seabird populations, including vulnerable and threatened species, and hosts economically important commercial fisheries and marine transportation corridors. Seasonal patterns of seabird movements and vessel traffic create a complex landscape of risk, defined as high levels of co‐occurrence ...
