Evidence of maternal provisioning of alkaloid-based chemical defenses in the strawberry poison frog Oophaga pumilio.
Many organisms use chemical defenses to reduce predation risk. Aposematic dendrobatid frogs sequester alkaloid-based chemical defenses from a diet of arthropods, but research on these defenses has been limited to adults. Herein, we investigate chemical defense across development in a dendrobatid frog, Oophaga pumilio. This species displays complex parental care: at hatching, mothers transport t...
متن کاملOntogenetic 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 ...

15 صفحه اولCross-modal integration in a dart-poison frog.
The mechanisms by which the brain binds together inputs from separate sensory modalities to effect a unified percept of events are poorly understood. 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...
متن کاملArthropod 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 ...
