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

open access: yesPLoS 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 ...

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

open access: yesBMC 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.

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

open access: yesMitochondrial 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]

open access: yesFrontiers 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

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

open access: yesPhyllomedusa: 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.

Phenotypic and molecular variation in the green and black poison-dart frog Dendrobates auratus (Anura: Dendrobatidae) from Costa Rica

open access: yesRevista de Biología Tropical, 2009
The green and black poison-dart frog Dendrobates auratus exhibits high intraspecific variation in hue color and pattern throughout its range, making it a very popular species in the pet trade.
