When it's just too darn hot, amphibian young adapt by changing their diet, weathering heat with vegetarian fare. In a new study, tadpoles representing three frog species were exposed to mock "heat waves" in the laboratory to test how amphibians in the wild might respond to warmer-than-average conditions due to climate change. Scientists are particularly interested in how the dietary needs of amphibians and other ectotherms, or "cold-blooded animals" — those that use external sources to regulate body temperature — may be affected by a warming world, the researchers wrote in the study.
