摘要

Branchiate Ambystoma talpoideum (Mole Salamanders) in fishless ponds can be large enough to act as predators, rather than competitors, during the spring breeding season of other amphibians. Food habits of high-density Mole Salamander populations from 2 proximate woodland ponds in Clark County, AR were examined before and after egg-laying by frogs, with an expectation that the salamanders likely would consume hatching tadpoles. However, salamanders instead commonly fed on the novel item of freshly-laid frog eggs. Results from both ponds indicated that the salamanders, perhaps due to food limitation, consumed smaller prey items than would be expected and heavily consumed frog eggs, a novel item.
