wfrc.usgs.gov — This study will compare relative abundance, population structure, and spawning success of desert pupfish from natural (reference) and manmade or disturbed habitats in the Salton Sea basin. In addition, this study will determine the importance of fish predation as a source of mortality in desert pupfish populations. Finally, this study will attempt More...

wfrc.usgs.gov — As anadromous juvenile salmonids migrate from freshwater rearing habitats to the ocean, they are vulnerable to a host of factors that affect their survival. Direct effects associated with dam passage (e.g., instantaneous mortality, injury, loss of equilibrium, etc.) and indirect effects (e.g., predation, disease, and physiological stress) More...
