This project is developed along three overlapping and interrelated lines of investigation: amphibian systematics, chemical defense, and ecology and conservation biology. We will set up a cleanroom laboratory to obtain DNA sequences from historical museum specimens and will develop and implement procedures to obtain DNA sequences from a new set of 1041 nuclear DNA markers using next-genera…
Comparative analyses of visual ecology and opsin complement are still lacking in amphibians. This is surprising given the success of the anuran radiation and the unique opportunities for vision research offered by the amphibian ontogenetic transition from aquatic to land life and the large variation in diel activity patterns across species. The purpose of this proposal is to bring Dr. Mic…
Amphibians employ chemical defenses against predators, pathogens, and/or parasites, often resulting in brilliant coloration, extravagant behaviors, and unique ecological interactions. Dr. Brodie is a pioneer in the fields of amphibian behavior and chemical defense with over 40 years of experience working on biological problems in Asia, North America, and Central America and nearly 200 pub…
Chemical defenses are widespread among animals and represent complex adaptations for avoiding predation, microbes, and/or parasites. Animals generally synthesize chemical defenses, although some species acquire defenses from external sources such as symbionts or dietary sources. Sequestration from diet involves the uptake, accumulation, and storage of defensive chemicals (or chemical prec…

Cutaneous exocrine granular glands of amphibians synthesize and secrete different compounds, including host defense peptides (HDPs). These HDPs are key molecules to defend against microorganisms, being especially widespread in anurans, and are potential biotechnological compounds for treating human infections caused by bacteria and fungi. The increasing number of antibiotic-resistant bact…
Crossodactylus is a genus of anurans belonging to the family Hylodidae. It is distributed from the state of Alagoas in northeastern Brazil to Misiones, Argentina, commonly found in streams located in mountainous regions of the Atlantic Forest or rocky fields. These frogs are diurnal and live near fast-flowing streams. Currently, 13 species are recognized within the genus, with only three …
Some animals avoid predation through aposematic signals, which can be chemical, acoustic, or visual. The use of coloration as an aposematic signal involves displaying bright and contrasting colors and patterns on their bodies, indicating the presence of defensive chemical compounds. This coloration warns potential predators about their profitability, indicating to the predator that they c…

Museomics has allowed the recovery of historical DNA (hDNA) from rare and extinct species, enabling otherwise intractable evolutionary problems to be resolved. However, challenges must be overcome in order to incorporate hDNA sequences into phylogenetic analyses. First, hDNA tends to be highly degraded, resulting in poor or ambiguous mapping to reference sequences. Consequently, different…
Chemical defense in Dendrobatidae species derives from lipophilic alkaloids, sequestered from ingested arthropods. Variation in alkaloid sequestration among species remain poorly understood, regarding both the diversity and quantity of these chemicals. For the first time in this study, it will be analyzed alkaloid profile (diversity, quantity and palatability) within six different sympatr…
The prepollex is a carpal element of anurans that exhibits extensive morphological diversity, including development into a conspicuous spine in clades nested within five distantly related families. This spine plays an important role during the reproductive period of territorial species, being used in male-male combat. Variation in prepollical morphology is associated with variation in sev…
The prepollex is a carpal element of anurans that exhibits extensive morphological diversity. Among this variety, it is developed into a conspicuous spine in clades nested in five distantly related families. Because it is used in male-male combats, this spine has an important role during reproductive period of territorial species. Its anatomy encompasses several muscles connected to disti…
