Journal of Applied Ecology, Volume 61, Issue 12, Page 3040-3052, December 2024.Our study shows that stressful conditions may trigger individual‐level trade‐offs in resource allocation and population‐level compensation among demographic rates. Demographic shifts arising from reintroductions in different environmental conditions may be considered by managers as a potential mechanism of resilience against environmental change ...

Identification, spatial distribution, and associated factors of urban protected areas in China
Conservation Biology, Volume 38, Issue 6, December 2024.Abstract The increasing proximity between protected areas (PAs) and urban areas, which can lead to urban protected areas (UPAs), is now commonplace. Use of Euclidean distance to measure the distance between PAs and cities has not correctly portrayed the spatial relationship between PAs and cities.
