Wildlife Ecology - Conservation - Wild Mammals - Behavior

We research the ecology, behavior, and conservation of mammals, ecological approaches for managing human-wildlife conflict, and exotic species management, among other areas of focus. 

Our lab has worked in Baja California Sur, Mexico, California, Colorado, Hawaii, and Santa Cruz Island, and on species such as the yellow-bellied marmot (Marmota flaviventris), golden-mantled ground squirrel (Callospermophilus lateralis), Koloa maoli (Hawaiian duck, Anas wyvilliana), mountain lion (Puma concolor), and pallid bat (Antrozous pallidus), among many others.  

Lab News 

Ellie and Dirk published a paper in the Journal of Mammalogy that investigates how island spotted skunks make fine-scale adjustments in microhabitat use and timing of activity that may help them avoid competitive interactions with island foxes. December 2021.

Caitlin and Dirk were featured in an article about the 30-year golden-mantled ground squirrel project at the Rocky Mountain Biological Laboratory.  This is a project Dirk started; Caitlin, Jackie, and Summer have conducted research on these squirrels.  

Ellie's research on island spotted skunks was highlighted in an article by The Wildlife Society.  

Ellie and Dirk published a paper in the Wildlife Society Bulletin investigating methods for detecting island spotted skunks on the Channel Islands. April 2020.

Amy published a paper in Biological Conservation on considering shifting baselines in conservation for both rare and common species. January 2020.

Jackie gave an oral presentation on personality-dependent spatial ecology at the UC Davis Wildlife, Fish, and Conservation Biology Seminar Series. December 2019.

Jackie, Aviva, and Dirk published a paper on ground squirrel relocation behavior in Ethology. November 2019.


Jackie and Dirk attended The Wildlife Society & American Fisheries Society 2019 Joint Annual Conference in Reno, Nevada. Jackie gave an oral presentation on bridging animal personality and space-use. September 2019.

Welcome new lab member, Summer Schlageter! Summer studies golden-mantled ground squirrel ecology at the Rocky Mountain Biological Laboratory.

Jackie gave an oral presentation on the effects of personality on ground squirrel spatial ecology at the UC Davis Animal Behavior Seminar Series. May 2019.

Ellie attended the 25th Annual Conference of The Wildlife Society in Cleveland, Ohio. Ellie gave an oral presentation on her research comparing detection methods for monitoring island spotted skunks. October 2018.

Amy and Ellie were co-authors on a paper published in the African Journal of Ecology detailing camera trapping trends across Africa. September 2018.

Jackie and Dirk attended the 98th Meeting of The American Society of Mammalogists in Manhattan, Kansas. Jackie presented a poster that quantified habitat selection in golden-mantled ground squirrels. June 2018.

Congratulations to Ellie, who won a National Science Foundation Graduate Research Fellowship. April 2018.

Jackie traveled to Missoula, MT as a Distinguished Fellow of IWFF Filmmaker Labs, a cross-disciplinary science filmmaking workshop led by the International Wildlife Film Festival and Days Edge Productions. April 2018.

The lab attended the 65th Annual Meeting of The Western Section of The Wildlife Society in Santa Rosa, California. Aviva presented a poster that compared the niches of three sympatric montane squirrel species, and Jackie presented a poster on litter translocations by yellow-bellied marmots. February 2018.
