Classification of skin alkaloids from neotropical poison-dart frogs (dendrobatidae)

Toxicon, 1978
Abstract Dendrobatid frogs have evolved an imposing number of unique alkaloids, apparently as a chemical defense against predation. Toxic skin extracts from a majority (18) of the approximately two dozen species of Dendrobates (sensu lato) were analyzed by thin-layer chromatography, gas chromatography and mass spectrometry.

Biologically Active Alkaloids from Poison Frogs (Dendrobatidae)

Journal of Toxicology: Toxin Reviews, 1982
AbstractA total of over one hundred biologically active alkaloids have been characterized in skin extracts from dendrobatid frogs. Five major classes have been defined: The highly toxic batrachotoxins are steroidal alkaloids which prevent interactivation of sodium channels in nerve and muscle.

Larval morphology of Dart-Poison Frogs (Anura: Dendrobatoidea: Aromobatidae and Dendrobatidae)

Zootaxa, 2013
Tadpoles in the superfamily Dendrobatoidea (families Aromobatidae and Dendrobatidae), housed in zoological collections or illustrated in publications, were studied. For the most part, tadpoles of species within the family Aromobatidae, the subfamilies Colostethinae and Hyloxalinae (of the family Dendrobatidae), and those of the genus Phyllobates ...

The evolution of myrmecophagy and its correlates in poison frogs (Family Dendrobatidae)

Journal of Zoology, 1996
Poison frogs (Family Dendrobatidae) are common leaf litter inhabitants of New World tropical rainforests. The name of this group derives from several genera (especiallyDendrobates, Minyobates,andPhyllobates) that are aposematically coloured and have toxic skin to varying degrees.

Chemical communication in the reproductive behaviour of Neotropical poison frogs (Dendrobatidae)

2014
Chemical communication is the evolutionary oldest communication system in the animal kingdom that triggers intra- and interspecific interactions. It is initiated by the emitter releasing either a signal or a cue that causes a reaction of the receiving individual.
