Observations on metamorphosing tadpoles of Hyalinobatrachium orientale (Anura: Centrolenidae)

Phyllomedusa: Journal of Herpetology, 2020
Observations on metamorphosing tadpoles of Hyalinobatrachium orientale (Anura: Centrolenidae). Metamorphosis, when anuran amphibians resorb their tails and remodel their mouthparts and internal organs, is a vulnerable stage in the frog’s life history. As

Diversity and function of the fused anuran radioulna. [PDF]

J Anat, 2022
Using finite element analysis, we find that the semi‐fused state of the frog forelimb bone experiences less von Mises stress than hypothetical fully fused or split conditions across multiple loading scenarios. The results support the idea that the semi‐fused state is an adaptation for saltation in frogs, and may be maintained by other forces such as ...

Cyanosis by methemoglobinemia in tadpoles of Cochranella granulosa (Anura: Centrolenidae)

Revista de Biología Tropical, 2010
Tadpoles inhabit generally well oxygenated rivers and streams, nevertheless they were found in areas with limited oxygen availability inside the rivers.

Explaining the anuran beta diversity by pond‐living tadpoles: the role of dispersal limitation and environmental gradients through multiple scales

Diversity and Distributions, Volume 29, Issue 12, Page 1609-1622, December 2023., 2023
Abstract Aim Determining drivers of beta diversity is a hugely complex task, as it involves processes acting synergistically across multiple scales. We employed a large‐scale standardized protocol to tease apart the environmental and spatial processes driving beta diversity patterns of pond‐living tadpoles across multiple scales.

How plants affect amphibian populations

Biological Reviews, Volume 97, Issue 5, Page 1749-1767, October 2022., 2022
ABSTRACT Descriptions of amphibian habitat, both aquatic and terrestrial, often include plants as characteristics but seldom is it understood whether and how those plants affect amphibian ecology. Understanding how plants affect amphibian populations is needed to develop strategies to combat declines of some amphibian populations.

Riparian buffers provide refugia during secondary forest succession

Diversity and Distributions, Volume 28, Issue 9, Page 2008-2019, September 2022., 2022
Abstract Aim Secondary forests regenerating from human disturbance are increasingly becoming a predominant forest type in many regions, and they play a significant role in forest community dynamics. Understanding the factors that underlie the variation in species responses during secondary succession is important for understanding community assembly ...

Elevational and local climate variability predicts thermal breadth of mountain tropical tadpoles

Ecography, Volume 2022, Issue 5, May 2022., 2022
The climate variability hypothesis posits that increased environmental thermal variation should select for thermal generalists, while stable environments should favor thermal specialists. This hypothesis has been tested on large spatial scales, such as latitude and elevation, but less so on smaller scales reflective of the experienced microclimate ...

Comparative analysis of amphibian genomes: An emerging resource for basic and applied research. [PDF]

Mol Ecol Resour
Abstract Amphibians are the most threatened group of vertebrates and are in dire need of conservation intervention to ensure their continued survival. They exhibit unique features including a high diversity of reproductive strategies, permeable and specialized skin capable of producing toxins and antimicrobial compounds, multiple genetic mechanisms of ...
