Combined with supporting research in reproductive physiology, identification of spawning habitat, and early life history this result provides new understanding of environmental factors that might affect reproduction of this endangered species.
Outlines tactical problems that make it difficult for beach managers to use scientific information to make beach closure and advisory decisions. Explains methodologies we are using to address those problems and better prepare local decision makers.
The Sacramento-San Joaquin River Delta is the hub of California's water system and an important habitat for fish and wildlife. USGS research has provided resource managers and other stakeholders with a good understanding of how pesticides enter the Delta.
