Habitat Characterization, Use, and Effects on Population Processes

• Near-shore habitat use by endangered juvenile suckers in Upper Klamath Lake, Oregon
• A field study of environmental variables influencing abundance and distribution of desert pupfish in the Salmon Sea Basin
• Water quality and other environmental variables associated with variations in population densities of the Santa Ana Sucker
• Habitat requirements of the endangered California freshwater shrimp in streams on the Point Reyes National Seashore and Golden Gate National Recreational Area
• Soldier Meadows
• Identification and thermal requirements of larval Pacific, river, and western brook lampreys and thermal requirements of early life history stages of lampreys
• Distribution, migration behavior, habitat use, and species interactions of fall-released juvenile hatchery spring chinook salmon in the Deschutes River, Oregon

Community Dynamics
