The squiggly grooves on dead logs are the telltale traces of bark beetles, which shape the lives and deaths of stressed-out trees.

California land and water managers are adopting genetic tools to monitor biodiversity, detect invasive and endangered species, and track how ecosystems change over time.

Storms on the California coast whip up frothy sea foam, which is like a planktonic meringue.

From creeping slime molds to brain-eating ciliates to kelp, protists may be the strangest and most misunderstood group of creatures in the tree of life.
