LIFE CHANGES Pantless treefrogs, the first frog species found that can deposit eggs either in water or out of it, might be able to adjust reproductive strategies if climate change disrupts local rainfall.

BOULDER, Colo. — Warming climate may dramatically change not just where animals live, but how. Solitary sweat bees in northern climes are projected to become builders of social colonies, researchers reported July 31 at the annual meeting of the Animal Behavior Society. Closer to the equator, fitful rainfall may drive tree frogs to exchange plants for ponds as their place to lay eggs.
