Zoologica Scripta, Volume 55, Issue 2, Page 220-231, March 2026.ABSTRACT South America, a region with high biodiversity, has been profoundly shaped by geological events during the Miocene and Pliocene, as well as by climatic changes in the Pleistocene, leading to complex phylogeographic patterns. The diverse biomes and the biotic exchanges between them, particularly between the Amazon and the Cerrado, have ...

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.

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.

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 ...

Escape behaviour in the Neotropical frog Hylodes asper (Anura: Leptodactylidae)
Acta Herpetologica, 2007 Predation is an important selective pressure in natural populations, leading to the bewildering diversity of antipredation strategies found in nature. However, studies focusing on real-time assessment and management of risks by prey are underrepresented ...

Reproductive biology of Pleurodema guayapae (Anura: Leptodactylidae: Leiuperinae).
Revista de biologia tropical, 2014 Pleurodema guayapae is a species that inhabits saline environments and semidesert zones from central Argentina. To date, the knowledge about the reproductive biology of this species is very poor, and our aim is to contribute to its knowledge with the description of some important reproductive aspects. For this, field work was undertaken in an area near

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.
