- Skin glands, poison and mimicry in dendrobatid and . . . - PubMed
Dorsal skin was studied histologically and histochemically, and skin secretions were submitted to sodium dodecyl sulfate polyacrylamide gel electrophoresis, reversed phase high performance liquid chromatography and assays for proteolytic activity
- Morphology of the granular secretory glands in skin of poison . . .
Observations The skin of dendrobatid frogs has the usual two types of amphibian integumentary glands, mucous glands and granular glands The granular glands of Dendrobates anthonyi will be described in detail and differences between these and glands of other species will be presented
- Histological Description of the Skin Glands of Phyllobates . . .
SUMMARY: The mechanisms to obtain and store skin toxins in frogs in of the family Dendrobatidae are not completely understood In order to contribute to understand how toxins are stored, we provide a histological description of the cutaneous glands of the species Phyllobates bicolor
- (PDF) Skin glands, poison and mimicry in dendrobatid and . . .
In amphibians, secretions of toxins from specialized skin poison glands play a central role in defense against predators The production of toxic secretions is often associated with conspicuous color patterns that warn potential predators, as it is the case of many dendrobatid frogs, including Ameerega picta
- Skin Glands, Poison and Mimicry in Dendrobatid and . . .
Among amphibians, the highest diversity of apo-sematic color patterns is found in poisonous frogs of the Dendrobatidae family, whose skin secretions are composed of a variety of dietary alkaloids, some of which are highly toxic to vertebrates (Daly et al , 2005)
- Skin glands, poison and mimicry in dendrobatid and . . .
This study tests for mimicry by studying the morphology and distribution of skin glands, components of skin secretion, and defensive behavior Dorsal skin was studied histologically and histochemically, and skin secretions were submitted to sodium dodecyl sulfate polyacrylamide gel electrophoresis, reversed phase high performance liquid
