Assessment of land‐based threats to Atlantic pelagic seabirds

Conservation Science and Practice, Volume 8, Issue 3, March 2026.
Highly mobile pelagic seabirds face numerous land‐based threats during their breeding seasons, including invasive alien species, climate change, and diseases, which drive population declines. Using field expertise and a literature review, we collated a dataset assessing 18 threats affecting 49 species across 38 Atlantic Large Marine Ecosystems. We used

High Fluctuating Asymmetry in Birds in a Large Neotropical City

Austral Ecology, Volume 51, Issue 2, February 2026.
Urbanisation is a powerful environmental force, negatively impacting the few organisms that persist in urban areas. Here, we investigated the relationship between urbanisation intensity and Fluctuating asymmetry (FA) in birds. Our results suggest that urbanisation (even at lower intensities) may impose stronger genetic and/or environmental stress on ...

Mapping area of habitat for inland wetland species

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Area of habitat (AOH) maps provide a high‐resolution representation of the habitat available in a species’ range and can support conservation policy and planning processes. However, until recently, there was insufficient knowledge on the distribution of inland wetlands and freshwater biodiversity to develop AOH mapping methods specifically ...
