caecilians, and are thought to be the source of most biologically active compounds in …

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 …

Dendrobates castaneoticus, new species, is a brilliantly colored small (18-23 mm SVL)
poison frog from lowland rain forest in Para, Brazil. It is black, with vivid white spots or …

Dendrobatid frogs produce a diverse set of alkaloids, whose profiles appear characteristic of
frogs of each species or, in the case of variable species, of each population. In the case of …

Poisons for arrows and blow darts have been derived from a wide spectrum of sources in
both the plant and animal kingdoms. One unique source of such poisons is the skin …

Bufonid poison frogs of the genus Melanophryniscus contain alkaloid-based chemical
defenses that are derived from a diet of alkaloid-containing arthropods. In addition to dietary …

Alkaloid profiles in skin of poison frogs/toads (Dendrobatidae, Mantellidae, Bufonidae, and
Myobatrachidae) are highly dependent on diet and hence on the nature of habitat. Extracts …
