Animal Conservation, Volume 29, Issue 1, Page 60-70, February 2026.Identifying the most effective criterion to assess the conservation status of vulnerable species in threatened tropical regions is crucial to evaluate recovery plans. We investigated the influence of environmental heterogeneity on the extent of occurrence (EOO), area of occupied habitat (AOH), and density variation of two Amazonian riparian frog ...

The Role of Environmental Factors on Visual Communication in Neotropical Anurans
Global Ecology and Biogeography, Volume 35, Issue 2, February 2026.ABSTRACT Aim Visual signals are a widespread behavioural attribute of communication among vertebrates, often employed during intrasexual competition or mate attraction, ultimately influencing reproductive success. However, the environmental factors driving visual signal evolution remain poorly understood.

Adaptaçoes, especializaçoes e linhagens nos anuros neotropicais
Acta Zoológica Lilloana, 2022 La taxonomía actual de Amphibia Anura es conservadora y casi exclusivamente morfológica. Las familias reconocidas son pocas y se basan en un pequeño número de caracteres osteológicos.

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 Stream Tadpoles ofRhinella rumbolli(Anura: Bufonidae)
Herpetologica, 2014 Abstract: The Rhinella veraguensis group is likely a paraphyletic assemblage that contains 16 species of Andean toads. To date, descriptions are available for larval stages of only three species, all of which possess a distinct sucker in the abdominal region.
