Environmental Physiology in a Changing Climate

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!

Chase, D. A., Flynn, E. E. and Todgham, A. E. 2016. Survival, growth and stress response of juvenile tidewater goby, Eucyclogobius newberryi, to interspecific competition for food. Cons. Physiol. 4: cow013. DOI: 10.1093/conphys/cow013.

Todgham lab students present at UC Davis undergraduate conference

Brigitte Clark (L) and Alexandra Resnick (R) presented their research at the 27th Annual Undergraduate Research, Scholarship and Creative Activities Conference (link). Brigitte shared her work on identifying ploidy (genome duplication) in white sturgeon while Alex discussed her research on the effects of climate change on the behavior of juvenile Antarctic fish.

New Publication! Antarctic fish: Cardiorespiration and Carbon Dioxide

PistenBully, Antarctica, Ross Sea

Britt’s first Antarctic paper in now available in the Journal of Experimental Biology! Read about her study looking at the effects of ocean acidification on a juvenile Antarctic fish (the emerald rockcod, Trematomus bernacchii) on the JEB website or under Publications.

Brittany Davis awarded a 2016 Delta Science Fellowship

Delta Smelt, oxygen consumption, Loligo

Britt, a PhD candidate co-advised by Dr. Nann Fangue, was recently selected to be 2016 Delta Science Fellow. She will study the effects of climate change on interactions between native and non-native fishes in the Delta. Read more about her research and other fellows at:


New Todgham Lab Publications!

Two new papers are hot off the presses featuring the master’s projects of lab alumni Daniel Chase and Christina Pasparakis. Dan’s  first thesis chapter on the effects of interspecific competition on juvenile endangered tidewater goby (Eucyclogobius newberryi) was recently published in the Transactions of the American Fisheries Society (DOI: 10.1080/00028487.2015.1106420). Christina’s research on the seasonal effects of preliminary heat exposure on thermal tolerance of the fingered limpet (Lottia digitalis) was also just published in Marine Biology (doi:10.​1007/​s00227-015-2779-5).

Congratulations to Madeline!

201512_MadelineisaMasterTodgham Lab member Madeline Kinsey has successfully completed her Master of Science degree with the Animal Biology Graduate Group. Her thesis examined the effects of temperature predictability on limpet thermal performance under natural tidal cycles. This work took her from the intertidal at Fort Ross to programming arduinos for her limpet habitats at SFSU Romberg Tiburon Center to many colorful assays in our lab here at UC Davis. More congratulations are in order as she has also been selected as a 2016 California Sea Grant State Fellow. She will work with the CA State Parks Natural Resources Division to help refine strategies and policies to better address climate change within the coastal parks. Great job, Madeline!
