Chinook salmon outmigration survival in wet and dry years in California's Sacramento River
Outmigration survival of acoustic-tagged, hatchery-origin, late-fall-run Chinook salmon (Oncorhynchus tshawytscha) smolts from the Sacramento River was estimated for 5 years (2007–2011) using a
Effects of acoustic tagging on juvenile green sturgeon incision healing, swimming performance, and growth
Current ultrasonic surgical tagging methods do not significantly affect the short-term growth or swimming performance of juvenile green sturgeon, and effects of surgery can be mitigated by minimizing the number of suture entry points and by using rapid-absorbing sutures.
The effects of environmental factors on the migratory movement patterns of Sacramento River yearling late-fall run Chinook salmon (Oncorhynchus tshawytscha)
Understanding smolt migration dynamics is a critical step in the preservation and conservation of imperiled salmonids in California’s Sacramento River system. Late-fall run Chinook salmon yearling
Stranding of Spawning Run Green Sturgeon in the Sacramento River: Post-Rescue Movements and Potential Population-Level Effects
Abstract The lower portion of the Sacramento River, California, has been highly engineered to protect low-lying surrounding communities from annual flood events. While engineered floodplains have
The effects of environmental context and initial density on symbiont populations in a freshwater cleaning symbiosis
It is demonstrated that initial symbiont density and environmental context can influence partner regulation by the host and cleaner reproduction and abundance in a cleaning symbiosis.
Reproductive dependence of a branchiobdellidan annelid on its crayfish host: confirmation of a mutualism
The results suggest that C. ingens is dependent on its crayfish host for reproduction, at least under environmental conditions in which cray fish survival and growth are enhanced by the worms.
Behavior, movements, and habitat use of adult green sturgeon, Acipenser medirostris, in the upper Sacramento River
We conducted the first continuous shipboard tracking of southern Distinct Population Segment green sturgeon, Acipenser medirostris, in the Sacramento River. Tracking of adult green sturgeon occurred
Diel movements of out-migrating Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Oncorhynchus mykiss) smolts in the Sacramento/San Joaquin watershed
We used ultrasonic telemetry to describe the movement patterns of late-fall run Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (O. mykiss) smolts during their entire emigration down
Use of RFID technology to characterize feeder visitations and contact network of hummingbirds in urban habitats
Efficient use of RFID technology to characterize feeder visitations and contact networks of hummingbird in urban habitats could be used in the future to elucidate behaviors, population dynamics and community structure of hummingbirds visiting feeders.
Ontogenetic Shifts and Symbiont Succession in a Freshwater Cleaning Symbiosis Mutualism
The results demonstrate that the outcome of the crayfish-branchiobdellidan association changes over cray Fish ontogeny, and host regulation and intraguild predation by C. ingens determine ectosymbiont succession in this mutualism.
