Risks of concealing environmental degradation

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Current practice seeks to conceal the visual impact of land‐use change (i.e., development). Six percent of development impact assessments in Australia and 14% of the World Bank's assessments recommend visual impact mitigation. This mitigation results in, for example, vegetated buffer strips alongside cleared agricultural areas and earthen ...

Continental‐wide prioritization of protected areas to address global and habitat‐specific goals for avian biodiversity conservation

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract The United Nations and European Union have set ambitious conservation goals to halt and reverse declines in biodiversity by protecting 30% of land and sea areas by 2030. Effective conservation planning requires evidence‐based spatial prioritization to maximize the coverage of species within designated protected areas.

Behavioral interventions to reduce demand for threatened freshwater turtles as pets

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

Assessing responses of reef island seabirds to environmental and anthropogenic drivers

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Identifying hotspots of faunal data deficiency to direct urgent research and monitoring

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...
