Poison frogs contain an alkaloid-based chemical defense that is derived from a diet of
certain alkaloid-containing arthropods, which include mites, ants, beetles, and millipedes …

Poison frogs contain an alkaloid-based chemical defense that is sequestered directly from a
diet of alkaloid-containing arthropods. Geographic and temporal variation in alkaloid …

A total of 232 alkaloids, representing 21 structural classes were detected in skin extracts
from the dendrobatid poison frog Oophaga pumilio, collected from 53 different populations …

Most amphibians produce their own defensive chemicals; however, poison frogs sequester
their alkaloid-based defenses from dietary arthropods. Alkaloids function as a defense …

Dendrobatid poison frogs sequester alkaloids from an arthropod diet and use them in
chemical defense. Alkaloid defenses vary considerably within and among species, with …

Conspicuously colored dendrobatid frogs sequester alkaloid defenses from dietary
arthropods, resulting in considerable alkaloid variation among populations; however, little is …

Dendrobatid poison frogs sequester lipophilic alkaloids from their arthropod prey to use as a
form of chemical defense. Some dendrobatid frogs seasonally migrate between the leaf litter …

Poison frogs sequester chemical defenses from arthropod prey, although the details of how
arthropod diversity contributes to variation in poison frog toxins remains unclear. We …

Defensive mechanisms, including noxious or toxic substances, are favored by predation-
driven natural selection. The acquisition of noxious/toxic substances can be either …

Neotropical poison frogs (Dendrobatidae) contain a wide variety of lipophilic alkaloids,
apparently accumulated unchanged into skin glands from dietary sources. Panamanian …
