Coral reefs, seagrass meadows and mangrove forests work together to make the Coral Triangle of Indonesia a hotspot for marine biodiversity. The system supports valuable fisheries and endangered species and helps protect shorelines. But it is in global decline due to threats from coastal development, destructive fishing practices and climate change.

A study of microbes that live in the nectar of flowers has turned up an unexpected result that challenges a common assumption in ecology.
It’s been widely assumed that the more easily organisms can disperse between habitats, the more similar the mix of species in those habitats will be.

To mark the bicentenary of Charles Darwin’s birth, we asked some UC Davis scientists who study evolution what they would say if they had the opportunity to write a letter to the naturalist. The results are featured on the campus home page today.
Mathematical geneticist Graham Coop regales Darwin with the tale of a gene that links stickleback fish directly to humans.
Geneticist David Begun confides that he and other modern-day scientists still share the sense of wonder that Darwin expressed when he wrote, “ … from so simple a beginning, endless forms most beautiful and most wonderful have been, and are being evolved.”
