Using biominerals to answer questions about fish spatial ecology, life history diversity, population structure and management.
I am interested in marine fish movements and stock structure, and how it ties into sustainable management. For my current (UCB) and previous (UCSC) postdoctoral positions I have been focusing on Chinook salmon (Oncorhynchus tshawytscha) life history diversity using otolith strontium isotopes. The position involves synthesizing and analyzing existing juvenile outmigration data, otolith microchemistry data, and environmental variables to understand mechanisms of life history diversity, habitat use and juvenile salmon survivorship.
Collecting salmon carcasses on the Stanislaus River as part of the CDFW annual carcass survey. The otoliths are then removed and we use their isotopic composition to identify origin and individual movement patterns
Water sampling in the Feather River, California, with George Whitman (UC Davis). The water samples help us map chemical changes in the environment that we can use to track individual salmon
My PhD centered around understanding the relationship between otolith microchemistry (trace element concentrations), physiological condition and ambient environmental conditions, using plaice (Pleuronectes platessa L.) as a model species. We carried out experimental work investigating the blood and otolith chemistry of juvenile and adult plaice under known conditions, and worked with otoliths from wild plaice tagged with electronic data storage tags (= 'known' movements). By temporally matching ambient conditions with otolith composition, we showed that some elements were under environmental control and could be a useful tool for reconstructing individual movement pathways, while other elements were primarily under physiological control and would be better suited to answering other types of questions, such as skipped spawning frequency.
