An Analysis Of Juvenile Chinook Salmon Outmigration Speed And Survival In Response To Habitat Features: Sacramento River From Knights Landing To Sacramento, California, Natalie N. Mcnair
An Analysis Of Juvenile Chinook Salmon Outmigration Speed And Survival In Response To Habitat Features: Sacramento River From Knights Landing To Sacramento, California, Natalie N. Mcnair
Master's Theses
Outmigration is an important life stage for Chinook salmon (Oncorhynchus tshawytscha) survival in the Sacramento River, and yet our understanding of their behavior and needs during this time is limited. To gain a better understanding of their survival and movement rates during outmigration, late fall run Chinook salmon smolts were tracked using acoustic telemetry techniques. Habitat features were measured and quantified throughout the study area to evaluate how Chinook salmon respond to key levee features including shade, instream woody material, and aquatic vegetation. The overall average movement speed through the entire study area was 0.77 m/s with an …
Effects Of Herbivory As An Ecological Constraint Of Willow Growth At A Restored Riparian Corridor, Jacqueline A. Mccrory
Effects Of Herbivory As An Ecological Constraint Of Willow Growth At A Restored Riparian Corridor, Jacqueline A. Mccrory
Master's Theses
A critical component of nearly all riparian restoration projects is the rapid successful recovery of native vegetation. The dynamic conditions and diverse biotic community supported by riparian ecosystems can present numerous constraints to restoration efforts. This study investigated stunted growth of arroyo willow (Salix lasiolepis) cuttings planted along the banks of Redwood Creek as part of the National Park Service’s Muir Beach Restoration Project to restore habitat for special status species in California. Based on observations of deer browsing, as well as signs of extensive biomass removal, I designed a field experiment using exclusionary fencing to test the significance of …
