Differences in characteristics between naturalized threatened plants and other threatened plants

Conservation Biology, EarlyView.
Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.

Providing regular and frequent maps of losses and gains of farmland birds based on European monitoring data

Conservation Biology, EarlyView.
Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

Amphibians' Expansion to Record Elevations Influences Chytrid (Batrachochytrium dendrobatidis) Infection Dynamics

Biotropica, Volume 58, Issue 2, March 2026.
Peruvian frogs underwent a climate‐driven range expansion into deglaciating mountains, exposing themselves and their fungal pathogen Batrachochytrium dendrobatidis (Bd) to challenging new thermal environments. Bd has dispersed extensively in these new habitats, and elevation may mediate the apparent sublethal impacts of infection for frogs.

Genetic origins and climate‐induced erosion in economically important Asian walnuts

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

A Framework to Analyze Primate Species Vulnerability to Trade in Urban Markets

American Journal of Primatology, Volume 87, Issue 12, December 2025.
A primate‐focused conservation criminology framework to examine taxon‐specific vulnerability to live trade in urban markets. ABSTRACT Live primates are increasingly commodified and appropriated as inputs into markets, both at the international and domestic scales, and across physical and online platforms.

Marked tree demographic variation along subtle elevation differences partially explains species' habitat associations in an Amazonian forest

Journal of Ecology, Volume 113, Issue 10, Page 2860-2874, October 2025.
These findings show that even small differences in elevation can lead to biologically meaningful variation in resource access that translates into significant differences in tree growth and survival. However, resource access could not fully explain the patterns of topographically driven demographic variation we observed. While certain species may still
