Tails of Biodiversity: Vertebrate Community Assessment in a Neotropical River Basin via eDNA Metabarcoding

Environmental DNA, Volume 8, Issue 1, January–February 2026.
This study used environmental DNA (eDNA) metabarcoding to assess vertebrate biodiversity in headwater streams of the Rio Santo Antônio basin, southeastern Brazil, a tributary of the Rio Doce. A total of 119 vertebrate OTUs were identified, with oxidation–reduction potential emerging as the strongest environmental predictor of species richness.

The Free‐Range Rock Cavy (Kerodon rupestris) Communicates the Urgency of a Threat Using Different Alarm Calls

Ethology, Volume 131, Issue 10, Page 175-186, October 2025.
Rock cavy alarm calls are finely modulated by threat proximity. ABSTRACT This study examines whether rock cavies (Kerodon rupestris), which are social rodents, modulate their alarm calls in response to various threat contexts. Conducted across four sample areas within two study sites in the Brazilian Caatinga region, alarm calls were collected using ...

Wild Encounters: Analyzing Human–Animal Interactions in British and Irish Association of Zoos and Aquariums Facilities

Zoo Biology, Volume 44, Issue 5, Page 461-473, September/October 2025.
We investigated the quantity and diversity of animal–visitor interactions in BIAZA‐accredited facilities, finding 740 opportunities for interactions across a range of contexts including walkthroughs and handling. Meet and greets were the most offered and were influenced by the number of individual animals, cost of interaction, and animal popularity ...
