Fall 2009
I investigated cellular mechanisms of ion and acid-base transport in rainbow trout (Oncorhyncus mykiss), crabs (Neohelice granulata), zebrafish (Danio rerio), Pacific hagfish (Eptatretus stoutii), and mosquito larvae (Aedes aegypti) with a primary focus on discerning the mechanisms governing ion...

Respiration, Acid/Base, Ammonia and Ionoregulatory Strategies in the Pacific hagfish (Eptatretus stoutii)
DownloadFall 2016
Hagfish feed on putrefied carrion, which poses several environmental challenges to the scavenger including hypoxia (Low PO2), hypercapnia (high PCO2) and high environmental ammonia (HEA). To any other organism, these conditions would be physiologically challenging; however, hagfish seem to have...

Responses to lowered salinity in the Pacific spiny dogfish, Squalus suckleyi, a marginally euryhaline shark
DownloadFall 2018
Euryhalinity is the ability to survive in multiple environmental salinities. Full euryhalinity is rare within the elasmobranchs (rays, skates, and sharks), however, marginal euryhalinity is comparatively more common. The physiology underlying these adaptations is relatively understudied in...

Toxicological Characterization of Hydraulic Fracturing Flowback and Produced Water Exposures to Aquatic Organisms
DownloadFall 2021
Hydraulic fracturing is an unconventional oil and gas extraction method used to liberate oil and gas reserves from low permeability geological formations by injecting large quantities of fracturing fluid into the well-bore under high pressures. A by-product of this process is flowback and...

Fall 2013
I have examined solute transport in two fishes at the whole-animal, tissue, and molecular levels. In the Pacific hagfish, I measured the kinetics of phosphate absorption in isolated gut, skin, and gill preparations, and implicated an NaPi-II transporter based on RT-PCR results and the kinetics of...
