Ontogenetic scaling of poison glands in a dendrobatid poison frog
The nature of chemical defenses in poison frogs has been explored in a variety of species, and most studies focus on the types of chemical defenses and their sources. The defensive compounds of frogs are stored in dermal granular glands that have been described for several species that are chemically protected from predators and/or microorganisms. Gland ultrastructure is known for some species ...

This phenomenon was studied in males of the dart-poison frog Epipedobates femoralis. These animals physically and vigorously defend their territories against conspecific calling intruders. In prior field studies with an electromechanical model fro...

15 صفحه اولArthropod predation in a dendrobatid poison frog: does frog life stage matter?
Frogs in the family Dendrobatidae are well known for their conspicuous colors and variable alkaloid-based chemical defenses. The aposematic coloration in dendrobatid frogs appears to deter predators with color vision, but relatively little is known about how these frogs are protected and their defenses are perceived by non-color vision dominated predators. The neotropical bullet ant Paraponera ...
متن کاملSearching for a Poison in a Poison
chlorinated biphenyl (PC8I mixtures had been described previously. High mortality, liver damage, and edema were associated with only two of the three PCB5. Using column and gas chromatography, several compounds were identified in the diethylether fracdon of these two PCBs. A chick embryo assay confirmed the high toxicity of this fraction. Mass spectremetric and microcoulometric analyses indicat...
