Todgham Lab: Environmental Physiology in a Changing Climate

We are continuing our collaborative research into the physiological and behavioral effects of thiamine deficiency on early development of salmonids. Here are some recently hatched spring run chinook salmon, which is a threatened run in California. It will still be a little over month before we start to see the spiral swimming behavior and mortality indicative of thiamine deficiency. Our research is looking into the benefits of reducing the negative effects of thiamine deficiency by injecting moms with thiamine prior to spawning in the hatcheries. Photo: Sarah Baird

The infamy of the skua.

We are excited to be part of this large, collaborative, multiagency effort to examine the link between thiamine deficiency and mortality in California Central Valley salmon. Heather Bell, a MS student in the lab, is leading the effort to uncover persistent sublethal effects on physiological performance of early life stages of Chinook salmon.

"The intertidal zone is a barometer of change for what's going on out in our oceans," marine ecologist and UC Davis professor Eric Sanford said. "These communit...ies are changing dramatically, not over the scale of centuries but over the scale of the 14 years I've been here."

Virtual Resources Now Available We know that teachers in the U.S. and abroad are adapting to virtual and hybrid classrooms during the pandemic. To assist teachers during this time, a number of PolarTREC lesson plans have been adapted for online teaching and assembled into a Collection of Virtual Resources. We hope that you will find these resources useful in your virtual classrooms. Other lesson plans are currently being adapted for virtual teaching so remember to revisit our website in the future for additional resources.
