The basis of my scientific curiosity has always been fish. Much of my work has been informed by telemetry systems to better understand movement ecology, habitat utilization, and behavioral responses to biotic and abiotic factors. While telemetry has been my primary tool of choice , many of the research questions I have worked on have been rooted in applied management, particularly for rare and/or endangered species such as Central Valley Salmonids, Green Sturgeon, and Arapaima. It is difficult to spend any significant time researching a species today without coming to the conclusion that the fundamental basis of your research is rooted conservation.
Currently, I am working on studies attempting to identify the “Portfolio Effect” within Green Sturgeon. The concept deals with population variability through understanding individual personalities, behavioral syndromes, and the relationship between spatio-temporal distributions within habitats. With respect to my salmonid work, we are currently working to better understand the behavioral responses to hydrodynamics as Chinook smolt emigrate to the ocean. This study is looking at the multi-dimensional movements of smolts through the use of multi-d tracking systems. Movement trajectories are paired with a highly resolved hydrodynamics model to understand the actual velocities, flow vectors, and shear zones used during migratory behavior. The ultimate goal is to provide an agent-based particle model which incorporates the range of behavioral responses observed, in an effort to produce a more informative model of potential route selection and entrainment risks associated with water operations to Central Valley Salmonids.
