Ecology and Evolution, Volume 16, Issue 1, January 2026.The purpose of this project was to evaluate the efficacy of eDNA sampling to determine occupancy of Coeur d'Alene salamanders, an “imperiled” species in Montana. Previous methods used to identify occupied sites were haphazard with no measure of detection probability. Due to the unique habitat used by these salamanders (seeps and waterfall spray zones),

THE ILIOSACRAL ARTICULATION IN PSEUDINAE (ANURA: HYLIDAE)
Herpetologica, 2005 We analyzed the iliosacral joint and iliolumbaris muscle anatomy of the species of Pseudinae, based on the two types of articulations defined by Emerson. Unusual characters should be expected in the pseudine iliosacral articulation structure, given their aquatic habits and evolutionary history.

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.

Journal of Zoology, Volume 328, Issue 1, Page 41-51, January 2026.Understanding how animals interact with their environment across life stages is key for conservation. In our long‐term study of the Blunt‐headed tree snake (Imantodes cenchoa) in the tropical rainforest of Los Tuxtlas, Mexico, we tracked over 240 individuals and found age‐related differences in environmental preferences.
