Aubry Lab Population Ecology in a Changing World

Quantitative Ecology

Lise Aubry, Associate Professor 
Department of Fish, Wildlife and Conservation Biology at CSU Graduate Program in Ecology

I am originally from Southern France and received a BS and MSc degrees from the Universite Paul Sabatier (France). I conducted my dissertation work at the Max Plank Institute for demographic research (Germany) where I studied life history trade-offs and senescence in vertebrates. I then moved to Utah State University to pursue postdoctoral research with a focus on wildlife management and human-wildlife conflicts. I then expanded my research program to include climate change impacts on wildlife. I moved to Colorado State University in 2017 to join the Fish Wildlife & Conservation Biology department where I receive tenure in 2021.

Originally from Texas, I came to Colorado to pursue a BS in Wildlife Biology from CSU and graduated in 2011. I recently finished my master’s degree at CSU and had the opportunity to conduct research on identifying fine-scale factors affecting habitat selection by white-tailed ptarmigan in Colorado’s gorgeous alpine. 

I have been lucky to have a variety of careers outside of the field of wildlife in law, finance, oil and gas, and environmental positions. However, my love for wildlife and ecology kept calling me back! My current research will focus on the dynamics, interactions, and conflicts between humans and black bears (see research section).

Co-advisor: Dr. Kate Huyvaert

Department of Fish, Wildlife and Conservation Biology at CSU

Graduate Degree Program in Ecology 


I completed my undergraduate studies at Adrian College with a BA in Biology, Environmental Science, and English. I have conducted soil research at NCSU and habitat research at Adrian. I also worked as a Wildlife Assistant for the Michigan Department of Natural Resources. Now, I am pursuing my MS here at CSU where I have a research project focused on the life strategies of small mammals.

CSU-SEEDS Chapter

I am an undergraduate student from Dallas, Texas who came to Colorado State University in 2017 to pursue a B.S. in Fish, Wildlife, and Conservation Biology. I am currently the Vice President of the Northern Colorado Herpetological Society where I help with education and outreach programs, as well as our reptile rescue operations. I was a Field Technician for the Colorado Checkered Whiptail project during the summer of 2019, and completed my Honors thesis project with Lise workingon the clutch size / egg size trade-offs in this all-female species. My plans for my future are to work in the fields of ecology, conservation, herpetology, and do some education work along the way!
Ryan Black, Undergraduate Research Fellow (2021-2022)


Originally from Southern California, I came to Colorado State University in 2018 to pursue a B.S. in Fish, Wildlife, and Conservation Biology. I am currently interning for Dr. Aubry to analyze the impacts of a large Colorado wildfire on golden mantled and Wyoming ground squirrel’s behavior and demography. I am interested in pursuing a career in wildlife ecology and studying and mitigating human-wildlife interactions around the world. I am intending on pursuing this career through graduate school while gaining technical skills domestically and internationally.

Caitlin P. Wells, Postdoctoral Fellow (2019-2021)



Caitlin's approach to applied conservation and restoration biology merges evolutionary ecology, animal behavior, and conservation genomics to predict the responses of wild vertebrates to environmental change. While a postdoc in the Aubry Lab, she worked on a variety of topics centered on understanding intra- and interspecific variation in the life-histories of wild vertebrates, as applied to the persistence of small populations. This led to the publication of the following manuscripts. Caitlin is now an Assistant Professor at CSU in the Fish Wildlife and Conservation Biology Department.

Douglas Eifler, Research Scientist (2018-2020)


Doug is a behavioral biologist with close to 30 years experience working with reptiles. He has graduate degrees in wildlife ecology (MS, University of Florida) and organismal biology (PhD, Harvard University). He is currently leading all field efforts on the Colorado checkered whiptail project, advising undergraduate studentS, wildlife technicians and volunteers in the field, helping them develop research projects on the behavioral ecology of whiptails. 


Samuel Hudgens, Honors student (2018-2020)


I am originally from Albuquerque New Mexico and moved to Fort Collins in 2016 to pursue a BS in Ecosystem Science and Sustainability at Colorado State University. I’m interested in conservation and carrying out research in the field. I aim to attain a graduate degree in ecology or a related science. Currently, I am assisting Shelley on a research project examining human-black bear conflicts using data from New Jersey Fish and Wildlife.

Caylee Falvo, MS student (2015-2018)



Caylee studied the effects of climate change on the physiology, demography, and phenology of Uinta ground squirrels. I use a combination of lab and field work to look at differences in life history strategies among populations that live at different elevations, in distinct climatic niches. She was particularly interested in life history trade-offs that involve immune function and fitness components, and how those are shaped by climate change. She received her undergraduate degrees at the University of California, Berkeley in Molecular Toxicology and Molecular Environmental Biology, and is broadly interested in the way wildlife populations and communities respond to anthropogenic change.

Caylee is now a PhD student in Raina PLowright's lab at Montana State University.

Liz McAlpine-Bellis (2018-2019) 


Field Technician 

[email protected]



Liz graduated from UC Berkeley in May (evolutionary biology) and plans to pursue a research career that will take her to lots of amazing places and let her study lots of interesting animals. Her research focuses on marine invertebrate response to climate change as well as aggression and territoriality in fish, lizards, and mantis shrimp. She likes fierce creatures and hopes to continue this research for a PhD.

Janine Rose Klein (2018-2019)


Field Technician 

[email protected]


I recently graduated from UC Davis with degrees in Wildlife Conservation Biology and Evolutionary Anthropology with an emphasis in primatology. Most of the research I participated in during my undergraduate career involved the behavior and movement of different species of lizards. I hope to soon pursue graduate work in this or a related field. My research interests include behavioral ecology, conservation biology, social networks in group-living species, and behavioral syndromes.

Rebecca John (2018-2019)


Field Technician 

[email protected]


I am an ecologist and herpetologist at heart. I earned my undergrad degree in Environmental Science and Biology from University of California, Santa Cruz and my master’s degree in Wildlife Sciences from Auburn University. I have been lucky enough to have travelled around the US (and beyond) working with tortoise, lizards, salamanders, bats, small mammals, fish, and more. My research interests are extensive and include natural history, behavior, ecology, biogeography, and movements.
