Fossil reefs from around the Caribbean show how biologically rich these ecosystems once were — and provide goalposts for conservationists hoping to restore them.
About 66 million years ago, a radical change on the Earth filled tropical forests with flowers. A new catalog of fossil pollen grains may hold an explanation.
Smithsonian scientists who documented massive mortality of corals and reef organisms meticulously studied one of the apparent causes: oxygen deficiency. A Smithsonian paleobiologist asks if the recent fossil record shows signs of similar hypoxia events.
Research projects in our lab combine approaches from behavioral ecology, functional morphology, ethology and evolution of behavior. Our work focuses mostly on the ultimate and proximate causes of behavior in an ecological and social context, with an emphasis on how ecological or social...
