Ex situ diet influences the bacterial community associated with the skin of red-eyed tree frogs (Agalychnis callidryas).

Amphibians support symbiotic bacterial communities on their skin that protect against a range of infectious pathogens, including the amphibian chytrid fungus. The conditions under which amphibians are maintained in captivity (e.g.

Differences in carotenoid accumulation among three feeder-cricket species: implications for carotenoid delivery to captive insectivores.

There are a limited number of feeder-invertebrates available to feed captive insectivores, and many are deficient in certain nutrients. Gut-loading is used to increase the diversity of nutrients present in the captive insectivore diet; however, little is known about delivery of carotenoids via gut-loading. Carotenoids may influence health and reproduction due to their roles in immune and antioxidant systems.
