Tidal Wetlands
Loss of tidal wetland habitat in the San Francisco Estuary affects fish and other aquatic organisms.
Longfin Smelt
Longfin Smelt is a threatened species found in waters along the Pacific coast. Its complex life cycle makes it vulnerable in both freshwater and at sea.
Sacramento Splittail
Spinal deformities in California native fish species, the Sacramento Splittail, are now attributed to exposure to the chemical element selenium.
The California Water Science Center's Aquatic Ecology Group is making great strides in research and reporting.
The Aquatic Ecology Group at the US Geological Survey’s California Water Science Center is a team of scientists working to solve important natural science challenges facing society.
Our research covers all aspects of aquatic ecology with a focus on freshwater, estuarine and marine fishes and environments. Particular topics include:
- Water resources
- Threatened and endangered species
- Fish habitat
- Food web dynamics
- Climate change
- Drought
We work closely with scientists in other disciplines at USGS to tackle challenges with comprehensive, interdisciplinary research. A particular strength of our group is the ability to use new technology to generate novel solutions to natural resource problems. We also maintain active collaborations with many federal, state, and local agencies, and universities.
We pursue innovative solutions to a diverse array of natural resource problems through applied research. A large portion of our research is field-based and incorporates elements of behavioral, population, and community ecology. Individual projects range from the biology and ecology of individual species to the effects of climate change on ecosystems.
