The green-and-black poison dart frog, or Dendrobates auratus, is a captivating amphibian native to southeastern Nicaragua, Costa Rica, Panama, and northwestern Colombia. Recognizable for its long lifespan, the species is also notable for being relatively easy to care for, making it an appealing choice for hobbyists and researchers alike. Its vivid mint-green base coloration punctuated with black splotches sets it apart visually. However, this species displays a fascinating trait known as color polymorphism. Individuals can exhibit varying shades, with base colors ranging from green to blue, yellow, and even white. The darker splotches, a characteristic signature of the species, vary from bronze to black. Just like other poison dart frogs, their bright colors serve a crucial evolutionary purpose. They exhibit aposematic coloration, wherein the vibrant hues deter potential predators by signaling the frog's toxic nature, discouraging them from considering the frog as prey. Primarily terrestrial, green-and-black poison dart frogs are bottom dwellers, spending most of their time navigating through the leaf litter blanketing the forest floor. However, they frequently venture upwards, climbing vines and trees in their tropical habitats. These frogs are attractive display animals for beginner and advanced amphibian enthusiasts. Their stunning coloration, coupled with their relative ease of care, make them popular choices for terrarium inhabitants. They are best kept as pairs or in gr...

Aromobates nocturnus and Colostethus saltuensis were found to be nested within Nephelobates, and Minyobates was paraphyletic and nested within Dendrobates.
The known diversity of dart-poison frog species has grown from 70 in the 1960s to 247 at present, with no sign that the discovery of new species will wane in the foreseeable future. Although this growth in knowledge of the diversity of this group has been accompanied by detailed investigations of many aspects of the biology of dendrobatids, their phylogenetic relationships remain poorly understood. This study was designed to test hypotheses of dendrobatid diversification by combining new and prior genotypic and phenotypic evidence in a total evidence analysis. DNA sequences were sampled for five mitochondrial and six nuclear loci (approximately 6,100 base pairs [bp]; x¯ = 3,740 bp per terminal; total dataset composed of approximately 1.55 million bp), and 174 phenotypic characters were scored from adult and larval morphology, alkaloid profiles, and behavior. These data were combined with relevant published DNA sequences. Ingroup sampling targeted several previously unsampled species, including Aromobates nocturnus, which was hypothesized previously to be the sister of all other dendrobatids. Undescribed and problematic species were sampled from multiple localities when possible. The final dataset consisted of 414 terminals: 367 ingroup terminals of 156 species and 47 outgroup terminals of 46 species.Direct optimization parsimony analysis of the equally weighted evidence resulted in 25,872 optimal trees. Forty nodes collapse in the strict consensus, with all conflict restricte...

18 apr 2019 · ... gene networks known to affect color and pattern in vertebrates play a role in color and pattern variation in this species of poison frog.
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. Here we have taken a transcriptomics-based approach to elucidate the underlying genetic mechanisms affecting color and pattern in a highly polytypic poison frog. We sequenced RNA from the skin from four different color morphs during the final stage of metamorphosis and assembled a de novo transcriptome. We then investigated differential gene expression, with an emphasis on examining candidate color genes from other taxa. Overall, we found differential expression of a suite of genes that control melanogenesis, melanocyte differentiation, and melanocyte proliferation (e.g., tyrp1, lef1, leo1, and mitf) as well as several differentially expressed genes involved in purine synthesis and iridophore development (e.g., arfgap1, arfgap2, airc, and gart). Our results provide evidence that several gene networks known to affect color and pattern in vertebrates play a role in color and pattern variation in this species of poison frog.
