Combining thermal and hydric constraints for spatially predicting the activity suitability of Neotropical Leptodactylid frogs

Ecography, Volume 2026, Issue 1, January 2026.
Amphibians balance their thermal and water budgets depending on their physiological state and the physical environment, with both factors capable of constraining activity. Most mechanistic assessments emphasize thermal over water constraints, potentially missing important aspects of amphibian ecophysiological patterns.

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.

Frog Diversity in Central Amazonian Macrophyte Beds: The Role of Local Environmental Gradients

Austral Ecology, Volume 50, Issue 12, December 2025.
ABSTRACT Ecological assemblages can be shaped by neutral, niche‐based processes, or a combination of both. Understanding the influence of these processes and evaluating diversity measures based on taxonomic, functional, and phylogenetic metrics on the structure of ecological assemblages can show patterns and unravel community assembly mechanisms ...

Cytogenetics of Edalorhina perezi(Anura, Leptodactylidae).

CYTOLOGIA, 2000
Specimens of Edalorhina perezi Jimenez de la Espada from the Brazilian Amazon were studied cytogenetically using Giemsa staining, silver staining and C-banding. The diploid complement of 2n=22 agreed with the chromosome number previously described for Edalorhina sp. Morphologically, the E.

Historical Fragmentation in Atlantic Forest Explains the Diversification of a Clade of Mountaintop Bromeligenous Frogs (Leptodactylidae: Crossodactylodes)

Zoologica Scripta, Volume 54, Issue 6, Page 823-839, November 2025.
ABSTRACT The Atlantic Forest domain is a biodiversity hotspot with remarkable amphibian diversity, including over 700 species, 70% of which are endemic. Most of these endemic species have restricted geographic ranges, often confined to mountainous areas, as exemplified by the leptodactylid genus Crossodactylodes.

Quantifying exposure of amphibian species to heat waves, cold spells, and droughts

Conservation Biology, Volume 39, Issue 5, October 2025.
Abstract Globally, amphibians face severe threats, such as climate change and associated extreme events. Our goal was to quantify global amphibian exposure to 3 classes of extreme events: heat waves, cold spells, and droughts. We used the MERRA‐2 extreme climate events data and the standardized precipitation–evapotranspiration index database to ...

Urban developmental environments alter tadpole phenotypes depending on origin

Journal of Animal Ecology, Volume 94, Issue 9, Page 1707-1719, September 2025.
Urbanisation has rapidly altered the ecological and evolutionary contexts for many species. Using a reciprocal transplant experiment with frog larvae, we find that urban environments can alter morphological, developmental and behavioural traits at both ecological and evolutionary scales.
