An uptake system for dietary alkaloids in poison frogs (Dendrobatidae)

Toxicon, 1994
The skin of poison frogs (Dendrobatidae) contains a wide variety of alkaloids that presumably serve a defensive role. These alkaloids persist for years in captivity, but are not present in captive-raised frogs. Alkaloids fed to poison frogs (Dendrobates, Phyllobates, Epipedobates) are readily accumulated into skin, where they remain for months.

Correlated Evolution of Conspicuous Coloration and Body Size in Poison Frogs (Dendrobatidae). [PDF]

Evolution; International Journal of Organic Evolution, 2003
Conspicuous coloration is often used in combination with chemical defenses to deter predators from attacking. Experimental studies have shown that the avoidance inducing effect of conspicuous prey coloration increases with increasing size of pattern elements and with increasing body size.

Pharmacological activity of alkaloids from poison-dart frogs (dendrobatidae)

Toxicon, 1978
Abstract Batrachotoxin, pumiliotoxin B, isodihydrohistrionicotoxin, pumiliotoxin C and gephyrotoxin represent five different classes of skin alkaloids from the dendrobatid poison dart frogs. In quinea pig ileum segments batrachotoxin and pumiliotoxin B caused rhythmic contractures which were prevented by tetrodotoxin.

Speciation with introgression: Phylogeography and systematics of the Ameerega petersi group (Dendrobatidae)

Molecular Phylogenetics and Evolution, 2019
The Tropical Andes contains exceptionally high diversity, much of it arising within the Quaternary period. The complex geology of the Andes and paleoclimate fluctuations within the Quaternary suggest complex speciation scenarios. This, in turn, has contributed to idiosyncratic speciation modes among shallowly diverged Amazonian taxa. Many relationships
