Environmental Physiology in a Changing Climate

New Publication: Physiological performance of diploid and triploid sturgeon in response to warming

Michaiah’s first sturgeon project is now published in Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology. Her work explores the differences in stress response, immunity and metabolism in white sturgeon of different ploidies acclimated to different temperatures. Read about it at Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology or under our Publications page. Congratulations Michaiah!

New Publication! Ocean acidification and hypoxia in rockfish: Behavior and Physiology

A collaborative project led by Todgham lab graduate student Brittany Davis is now available at Conservation Physiology. Her work investigated the effects of CO2-acidification and hypoxia on predator prey interactions as well as metabolism. She observed compensatory responses after an acclimation period that suggest these fish may be resilient to environmental changes predicted to occur with climate change. Read all about it at Conservation Physiology or under Publications!

Lab outreach events a success!

This spring several Todgham lab members participated in three outreach events to share our research with the public. At the annual UC Davis campus open house, Picnic Day, we had a station all about sturgeon. We had both tiny 1 month old sturgeon to view and larger 11 month old sturgeon in a touch tank so guests could experience sturgeon up close. 

 

Lab members also visited two elementary schools. We had a station at Marguerite Montgomery Elementary School’s Science Expo here in Davis. Activities focused on the lab’s Antarctic research from current threats facing Antarctic fish and how we study physiology to the challenges of conducting research in Antarctica.

At Marion Mix Elementary in Elk Grove we visited a 6th grade classroom. We had a lot of fun teaching this enthusiastic class about salmon conservation, Antarctic fish physiology, and how we came to be graduate students.

 

 

Undergraduates awarded departmental scholarships

Two of our stellar undergraduates were awarded scholarships from the Department of Animal Science and honored at the Animal Science Spring BBQ. Lorenzo was awarded the Gary P.  Moberg Memorial Award and Gabi received the Elizabeth Graves Hosselkus Scholarship. Congratulations!

Gabriella Mukai awarded NOAA Hollings Scholarship

Todgham lab undergraduate student Gabi Mukai was selected for the 2018 class of NOAA Hollings Scholars. Through the Ernest F. Hollings Scholarship she will receive financial aid as well as research experience at a NOAA facility. Congratulations Gabi!

Todgham lab students present at UC Davis undergraduate research conference

Three Todgham lab undergraduate students presented posters of their research at the 29th annual Undergraduate Research, Scholarship and Creative Activities Conference.  Gabi Mukai and Lorenzo Olano presented their study of inducible stress tolerance in juvenile Chinook salmon. Bryan Puentes discussed a project studying the effects of temperature and feed restriction on white sturgeon. Andrew Naslund shared his work on the effects of ocean acidification on the growth of otoliths (ear bones) in juvenile Antarctic fish. They all worked very hard on their research projects this year and did a great job presenting!

Tinh Ton awarded NSF Graduate Research Fellowship

Graduate student Tinh Ton was awarded a competitive 2018 NSF Graduate Research Fellowship that will support his work studying KEYSTONEin in relation to mussel physiology and behavior. Congratulations Tinh!

Congratulations Dr. Davis!

Todgham lab member Brittany Davis successfully completed her PhD in the Animal Biology graduate group. Her dissertation “Susceptibility of Juvenile fishes to environmental change: Linking physiological responses to behavioral outcomes” focused on research conducted all the way from Antarctica to the California coast at the Bodega Marine lab to the local Bay Delta estuaries. We wish Britt the best of luck as she begins her new job at the California Department of Water Resources.

Erin Flynn awarded research funding!

PhD student Erin Flynn received a Jastro Shields research award from the College of Agriculture and Environmental Studies for her Antarctic studies exploring impacts of global climate change on Antarctic dragonfish eggs. Erin also was awarded a fellowship for next year from the Graduate Group of Ecology at UC Davis.

Congratulations Erin!

New Publication! California Estuarine Fishes: Food and Competition

Dan’s second chapter of his Master’s project is now available at Conservation Physiology. His work shows how food limitation interplays with competition between the endangered tidewater goby (pictured above, held by Dan) and either a native (threespine stickleback) or an introduced species (rainwater killifish). Read about it at Conservation Physiology or under Publications!
