Mission Areas
Ecosystems
The USGS Ecosystems Mission Area, the biological research arm of the Department of the Interior (DOI), provides science to help America achieve sustainable management and conservation of its biological resources. This work is done within the broader mission of the USGS to serve the Nation with science that advances understanding of our natural resources and inform land and water stewardship.
Collaborative Conservation
What do gray wolves, manatees and bears have in common? They are just a few of the species that are part of important USGS research that informs U.S. Fish and Wildlife Service decisions for endangered and threatened species.

Kreitler, Jason R.; East, Amy E.; Sankey, Joel B.; Tague, Christina (Naomi) A space-time geostatistical model for probabilistic estimation of harmful algal bloom biomass and areal extent
Harmful algal blooms (HABs) have been increasing in intensity across many waterbodies worldwide, including the western basin of Lake Erie. Substantial efforts have been made to track these blooms using in situ sampling and remote sensing. However, such measurements do not fully capture HAB spatial and temporal dynamics due to the limitations of...
