Terrestrial, Freshwater, and Marine Ecosystems Program's Research Topics

Arid Lands Arid lands host diverse and easily disturbed plant and animal communities.	Coral Reefs Coral reefs are under siege from disease, disturbance and degraded water quality.
Fire Fire is an important part of many arid environments.	Forests Forest ecosystems are undergoing large shifts due to climatic changes.
Global Change Ecosystem changes range from destruction of Gulf Coast wetlands to alterations in Alaskan tundra.	Grasslands Grassland communities are vulnerable to a host of stressors.
Interdisciplinary Ecosystems Science Ecosystem problems require diverse scientific expertise.	Mountains Montane environments are not as isolated as they once seemed.
Outer Continental Self Continental shelf research helps guide Department of Interior management actions.	Urban Expansion Changes in species composition and loss of habitat accompany urban expansion.
Wetlands Wetlands are important buffers for coastal and fluvial environments.
