Justin K Clause - California Water Science Center
Justin K. Clause recieved his Bachelors Degree from University of California Davis in 2014. Since then, he has worked in California and abroad focusing on Conservation, Restoration, Ecology, and Education. The majority of his work has focused on the ecology and life history of fishes, reptiles, and amphibians, although he also has extensive experience with invertebrates. He has worked with the Aquatic Ecology group of the California Water Science Center since 2017. His most recent work focuses on quantifying the benefits of restoration actions in the North Delta of California.

Distribution and stomach contents of fishes in the northern Sacramento-San Joaquin Delta, 2020-2022
This data set includes count, location, and ancillary habitat data for fishes sampled in adjacent reaches of Georgiana Slough, Sacramento River, and Steamboat Slough in the northern Sacramento-San Joaquin Delta. It also includes data on the stomach contents of selected individual black basses (Micropterus). Fishes were sampled by boat electrofishing from approximately January-May, 2020-2022, plus

Abundance and Distribution of Clear Lake Hitch in Clear Lake, Lake County, California, 2017-2022 (ver. 4.0, December 2022)
Field data for fishes sampled using bottom and surface gill nets during daylight hours in Clear Lake, California, USA. This data release includes all measured environmental parameters and fish taxa included in the analysis.
Wetland geomorphology and tidal hydrodynamics drive fine-scale fish community composition and abundance
Effective restoration of tidal wetlands for fish communities requires clear goals and mechanistic understanding of the ecosystem drivers which affect fish distribution and abundance. We examined fish community responses to abiotic habitat features in two adjacent but dissimilar freshwater tidal wetlands in the Sacramento-San Joaquin Delta, CA, USA, each of which represents a potential restoration

Eye lenses reveal ontogenetic trophic and habitat shifts in an imperiled fish, Clear Lake hitch (Lavinia exilicauda chi)
Stable isotopes recorded in fish eye lenses are an emerging tool to track dietary shifts coincident with use of diverse habitats over the lifetime of individuals. Eye lenses are metabolically inert, sequentially deposited, archival tissues that can open avenues to chronicle contaminant exposures, diet histories, trophic dynamics and migratory histories of individual fishes. In this study, we demon
