Tadpole morphological characterization of Ranitomeya variabilis (Zimmermann & Zimmermann, 1988) (Anura: Dendrobatidae), with skeleton, muscle system and inner organs
In this study, we morphologically examine larval specimens of Ranitomeya variabilis , which were breed in captivity and genetically determined to...

Eating to the beat of the drum: vibrational parameters of toe tap** behavior in Dendrobates truncatus (Anura: Dendrobatidae)
Toe tap** is performed by certain anuran species while foraging for their prey. This behavior has been described in different frog families, with...

Home range and notes about social interactions in the poison frog Phyllobates vittatus (Anura: Dendrobatidae)
Understanding animal movements is vital for gaining insights into species' ecological patterns, habitat preferences, and reproductive strategies....

Developments in the study of poison frog evolutionary ecology I: social interactions, life history and habitat use across space and ontogeny
Poison frogs of the superfamily Dendrobatoidea have fascinated researchers since the 19th century, which is reflected in multiple studies on their...

Identification of the NA+/K+-ATPase α-Isoforms in Six Species of Poison Dart Frogs and their Sensitivity to Cardiotonic Steroids
Cardiotonic steroids (CTS) are a group of compounds known to be toxic due to their ability to inhibit the Na + /K + -ATPase (NKA), which is essential to...
-
Experimental evidence in a poison frog model suggests that tadpole transport on the dorsum may affects warning signal effectiveness in poison frogs
Aposematism is an anti-predator strategy where predators learn to associate the warning signal on prey with an unpleasant experience, and...

Conspicuous and cryptic poison frogs are picky and prefer different meals in syntopy
The poison frog family (Anura: Dendrobatidae) consists of species with conspicuous (e.g., warning coloration and toxicity or low palatability) and...

Genetic Diversification of Adelphobates quinquevittatus (Anura: Dendrobatidae) and the Influence of Upper Madeira River Historical Dynamics
The effect of large Amazonian rivers as barriers to distribution of species and gene flow has been the subject of debate for more than a century. The...

Toxicity and Alkaloid Profiling of the Skin of the Golfo Dulcean Poison Frog Phyllobates vittatus (Dendrobatidae)
Frogs in the genus Phyllobates are known for the presence of batrachotoxin, a highly toxic alkaloid, in their skin. Nevertheless, Phyllobates frogs...

Eco-Metabolomics Applied to the Chemical Ecology of Poison Frogs (Dendrobatoidea)
Amphibians are one of the most remarkable sources of unique natural products. Biogenic amines, peptides, bufodienolides, alkaloids, and volatile...

Right or left-handed: are locomotion type, body size, and microhabitat related to forelimb laterality in anurans?
Laterality, the tendency of animals to use the structures on one side of the body more frequently or efficiently than the other side, can reflect the...

Mother strawberry poison frogs might supplement nutritive eggs with secretory provisioning
Many animal lineages produce and provision offspring with nutritive material such as milk, lipid-enriched skin, or mucus. Some frogs deposit...
-
The molecular basis and evolution of toxin resistance in poison frogs
Many animals bear conspicuous warning signals that advertise toxin-mediated unpalatability to predators; this is known as aposematism. Frogs in...
-
Under pressure: evidence for selection on color-related genes in poison frogs of the genus Ranitomeya
Aposematic organisms rely on their bright conspicuous coloration to communicate to potential predators that they are toxic and unpalatable. These...

The ability to sequester the alkaloid epibatidine is widespread among dendrobatid poison frogs
Dendrobatid poison frogs sequester alkaloids from an arthropod diet and use them in chemical defense. Alkaloid defenses vary considerably within and...
-
How Phylogenetics Can Elucidate the Chemical Ecology of Poison Frogs and Their Arthropod Prey
The sequestration by neotropical poison frogs (Dendrobatidae) of an amazing array of defensive alkaloids from oribatid soil mites has motivated an...
-
Comparative genomics reveals insights into anuran genome size evolution
BackgroundAmphibians, particularly anurans, display an enormous variation in genome size. Due to the unavailability of whole genome datasets in the...

Isolation and characterization of 12 microsatellite loci in Epipedobates anthonyi (Amphibia: Anura: Dendrobatidae) for population genetic analysis
Tropical anurans are among the most diverse and vulnerable organisms on Earth, yet the evolutionary mechanisms behind their diversity remain...
-
Integrating ecological niche modeling and rates of evolution to model geographic regions of mimetic color pattern selection
Geographic variation in natural selection derived from biotic sources is an important driver of trait evolution. The evolution of Müllerian mimicry...

Historical biogeography highlights the role of Miocene landscape changes on the diversification of a clade of Amazonian tree frogs
The diversification processes underlying why Amazonia hosts the most species-rich vertebrate fauna on earth remain poorly understood. We studied the...
