An addition to the diversity of dendrobatid frogs in Venezuela: description of three new collared frogs (Anura: Dendrobatidae: Mannophryne) [PDF]
Phyllomedusa: Journal of Herpetology, 2010 Three new species of collared frogs of the genus Mannophryne are described from Venezuela. Two are newly discovered taxa from the Venezuelan Andes, whereas the third species, previously confused with M.

A new species of Leucostethus (Anura, Dendrobatidae) from Gorgona Island, Colombia [PDF]
ZooKeys, 2021 We describe a new species of Leucostethus from Gorgona Island, a small (13 km2) island located 35 km from the Pacific coast of southern Colombia. The new species most resembles L. argyrogaster and L. fugax from western Amazonia at 340–870 m elev. in Peru

Analysis of morphological attributes as a driver of trade in poison dart frogs. [PDF]
Conserv BiolAbstract The unsustainable use of wildlife is a threat to biodiversity on a global scale, and the insatiable demand is driven by the attributes of the species, their parts, and derivatives. However, not all species are equally valued; certain attributes command a higher price. One example is the exotic pet trade in amphibians and reptiles.

Pigments, Chromatophore Structure, and Gene Expression Underlying Colour Polytypy of a Panamanian Poison Frog. [PDF]
Mol EcolABSTRACT Colour polytypism represents an example of phenotypic diversification shaped by genetic divergence and ecological pressures. Poison frogs of the genus Oophaga (Dendrobatidae) are highly polytypic in coloration, making them an ideal system for investigating the genetic and physiological basis of colour variation.

Histological and Gene Expression Analyses of the Arm and Finger Macroglands of Two Hyloxalus Frogs (Dendrobatidae). [PDF]
Mol EcolABSTRACT Chemical communication during courtship is well documented in salamanders and newts, but its role in frogs is less understood. In some Neotropical poison frogs, males exhibit specialised mucous glands (SMGs) in the hand integument that express high levels of sodefrin precursor‐like factors (SPFs), an amphibian pheromone. Some species also show

Captive Breeding Reveals Insights Into the Ecology and Reproductive Biology of 11 Little-Known Malagasy Frog Species. [PDF]
Zoo BiolAmphibian conservation efforts are limited by a lack of knowledge about their life history traits. At a conservation breeding facility in Andasibe, Madagascar, we observed diverse breeding patterns and egg numbers among 11 frog species, revealing links between reproductive strategies and environmental factors.

Don't You Know That I'm Toxic? Wild Birds Learn to Avoid a Novel Aposematic Warning Signal. [PDF]
Ecol EvolThe foraging behaviours of predators towards aposematic prey have been studied extensively and there is much empirical evidence to support this theory. Often, studies involving wild species are relatively short‐term and so there is a possibility that any aversive behaviours exhibited by predators are merely neophobic. In this study, we ensure predators

Genome size evolution and phenotypic correlates in the poison frog family Dendrobatidae. [PDF]
Evolution, 2023 Abstract Adaptive and neutral processes have produced a spectrum of genome sizes across organisms. Amphibians in particular possess a wide range in C-values, from <1 to over 125 pg. However, the genome size of most amphibians is unknown, and no single family has been comprehensively assessed.
