Using Environmental DNA Sampling for Simultaneous Detection of Hosts and Their Pathogens: A Case Study With the Critically Endangered Frog Genus Atelopus

Animal Conservation, Volume 28, Issue 5, Page 663-674, October 2025.
Environmental DNA is a powerful tool for simultaneous detection of rare species and their pathogens. We confirmed the presence of Atelopus at multiple sampling locations and found that the concentration of the amphibian pathogen Bd in eDNA samples was correlated with stream characteristics and the pathogen load of the amphibian community.

Host species and age‐specific variation on Hepatozoon prevalence and its effect on body condition in two Neotropical crocodiles

Wildlife Biology, Volume 2025, Issue 5, September 2025.
Many populations of species belonging to the order Crocodilia are threatened due to illegal trafficking, indiscriminate hunting, and habitat loss and degradation affecting crocodilian health and parasitic load. Although several studies have revealed that crocodiles, caimans, and alligators are frequently infected by Hepatozoon spp., the results from ...

Range‐restricted species are poor proxies for functional diversity in the world's largest avifauna

Conservation Science and Practice, Volume 7, Issue 9, September 2025.
We assessed the relationship between avian taxonomic richness (four metrics) and functional diversity (three metrics) across Colombia, the country with the most bird species. We found total species richness and threatened species richness to be suitable proxies for both functional richness and evenness. Protecting the eastern slope of the Eastern Andes

Grouped and Vibrating: The Influence of Group Size, Triggering Stimuli, and Leg Loss in Bobbing in an Arachnid

Ethology, Volume 131, Issue 5, May 2025.
ABSTRACT Animals across taxa form aggregations, with increased defenses as one of the benefits. Some defensive behaviors of grouped animals involve body movements. However, how those behaviors are triggered varies, and how between‐individual morphological variation affects them remains unknown.
