Predator response to the coloured eyespots and defensive posture of Colombian four‐eyed frogs

Journal of Evolutionary Biology, Volume 36, Issue 7, Page 1040-1049, July 2023., 2023
Using stationary artificial frogs exposed to wild predators, we tested whether the eyespot/colour markings and defensive posture present in the putative deimatic display of Colombian four‐eyed frogs, and their combination, provide protection from predation without a sudden change in appearance.

Systematics and historical biogeography of Neotropical foam-nesting frogs of the Adenomera heyeri clade (Leptodactylidae), with the description of six new Amazonian species

Zoological Journal of the Linnean Society, 2020
A large proportion of the biodiversity of Amazonia, one of the most diverse rainforest areas in the world, is yet to be formally described. One such case is the Neotropical frog genus Adenomera.

Antimicrobial, cytotoxic, and insulin‐releasing activities of the amphibian host‐defense peptide ocellatin‐3N and its L‐lysine‐substituted analogs

Journal of Peptide Science, Volume 29, Issue 4, April 2023., 2023
Substitution of Asp4 by L‐Lys ([A4K]) in the frog skin peptide ocellatin‐3N led to a 4–16‐fold increase in antimicrobial activity against both Gram‐positive and Gram‐negative bacteria and a 2.5–4‐fold increase in cytotoxic potency against human tumor‐derived cells.

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 ...

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.
