Variation in pigmentation gene expression is associated with distinct aposematic color morphs in the poison frog Dendrobates auratus [PDF]

BMC Evolutionary Biology, 2019
Background Color and pattern phenotypes have clear implications for survival and reproduction in many species. However, the mechanisms that produce this coloration are still poorly characterized, especially at the genomic level.

Kin discrimination in cannibalistic tadpoles of the Green Poison Frog, Dendrobates auratus (Anura, Dendrobatidae) [PDF]

Phyllomedusa: Journal of Herpetology, 2009
Cannibalizing a related individual can reduce the inclusive fitness of the cannibal. Hence, mechanisms that allow a tadpole to recognize and modify its behavior toward kin may reduce the inclusive fitness costs of cannibalism.

Body size but not warning signal luminance influences predation risk in recently metamorphosed poison frogs. [PDF]

Ecol Evol, 2015
This is the final version of the article. Available from Wiley via the DOI in this record.During early development, many aposematic species have bright and conspicuous warning appearance, but have yet to acquire chemical defenses, a phenotypic state ...

Reproductive activity of the frog Dendrobates auratus Girard in captivity breeding [PDF]

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010
Research of the reproduction activities of Dendrobates auratus Girard, 1855 is part of a broader ana­ly­sis of the problems encountered when keeping frogs from the family Dendrobatidae in captivity.

Sodium ion channel alkaloid resistance does not vary with toxicity in aposematic Dendrobates poison frogs: An examination of correlated trait evolution. [PDF]

PLoS ONE, 2018
Spatial heterogeneity in the strength or agents of selection can lead to geographic variation in ecologically important phenotypes. Many dendrobatid frogs sequester alkaloid toxins from their diets and often exhibit fixed mutations at NaV1.4, a voltage ...

The mitochondrial genomes of three species of poison frogs (Anura: Dendrobates) [PDF]

Mitochondrial DNA. Part B. Resources, 2017
We reconstructed nearly complete mitogenomes for three species of poison frogs, Dendrobates auratus, D. leucomelas, and D. tinctorius, from RNAseq data. We recovered the 13 protein-coding genes, 22 tRNA genes (except tRNA-Val for D.

Environmental and Host Effects on Skin Bacterial Community Composition in Panamanian Frogs [PDF]

Frontiers in Microbiology, 2018
Research on the amphibian skin microbiota has focused on identifying bacterial taxa that deter a pathogenic chytrid fungus, and on describing patterns of microbiota variation. However, it remains unclear how environmental variation affects amphibian skin

Transcriptomic Signatures of Experimental Alkaloid Consumption in a Poison Frog. [PDF]

Genes (Basel), 2019
In the anuran family Dendrobatidae, aposematic species obtain their toxic or unpalatable alkaloids from dietary sources, a process known as sequestering.

No evidence of quantitative honest signaling in aposematic traits of the green and black dendrobatid frog <i>Dendrobates auratus</i> in Costa Rica. [PDF]

Curr Zool
Abstract Aposematism is an antipredator strategy in which conspicuous coloration acts as a warning of chemical defenses to potential predators. Evidence suggests that aposematism largely functions under positive frequency-dependent selection, which is thought to maintain uniformity of aposematic signals.
