University of Alberta

My research investigates how resource availability affects maternal investment, development of offspring, and lifetime reproductive success in boreal mammals. I wish to determine how individual behavioral and life history responses to current conditions are shaped by past conditions and future trade-offs. For over 25 years my students and I have used field studies of individual red squirrels and experimental manipulation of their environment to investigate these questions.

Dr. Ben Dantzer

University of Michigan

My research focuses on questions that integrate animal behavior, physiology, and evolutionary ecology. I am interested in understanding the factors shaping the evolution of behavioral and life history traits as well as how physiological traits both mediate but also constrain variation in life history and behavioral traits. In red squirrels, I study the mechanisms and evolutionary consequences of early life experiences among other questions. I use a combination of long-term data coupled with large-scale experimental manipulations and laboratory analyses to address my research questions.

I’m interested in the ways in which individuals and populations respond to short- and long-term variation in their natural environments. I combine theory and techniques from ecology, evolutionary biology, quantitative genetics and physiology to meet this challenge, and primarily work with wild mammal populations that have been studied for multiple decades. Red squirrels are an ideal study system in this sense, because we can track individuals across their entire lives, scale our individual data up to population-level metrics and quantify their primary food resource (white spruce seed).

April is an ecologist who asks nosy questions about why animals leave home - and what kind of trouble they get into when they do. Her research blends field grit, data science, and ecological theory to understand how individual quirks shape life’s big decisions. April’s specialty lies in making complicated models look cool and somehow distilling billions of movement points into something relatable all while mentoring students who don’t think they belong in science (but definitely do). She’s also a former varsity wrestler and current wrestling coach, which turns out to be excellent training for academia. Outside of academia, she applies the same obsessive energy to climbing, coaching wrestling, and curating a minimalist aesthetic that exists mostly in theory (if you don’t count books, climbing gear, and spreadsheets).

Dr. Andrew McAdam

University of Colorado

I am interested in the interactions between ecology and contemporary adaptation. I use long-term pedigrees and experimental manipulations of resources and relatedness to quantify key ecological and quantitative genetic parameters. The goal of these investigations is to understand how an organism’s unique ecology contributes to contemporary patterns of selection and evolution.

My lab developed microsatellites for red squirrels that we use for pedigree analyses. Paternity and kinship analyses make it possible to conduct quantitative genetic analyses, and to study the mating system and spatial genetic structure of the Kluane population. In the future we plan to use comparative genomics to identify the genes that determine adaptive variation in sciurids.

Being able to respond rapidly and effectively to challenges is key to fitness. The stress axis is central to making this happen. The stress response can vary among animals because of variation in maternal quality, of genetics, and of environment (poor vs good territories) and deteriorate as aging proceeds. Red squirrels are ideal, long-lived mammals to study these changes and to test hypotheses of aging, of life history constraints, etc. This research examines all aspects of the stress axis from the brain mechanisms, endocrinology, and energetics and links it into complementary studies going on simultaneously on behavior, genetics, and food manipulations.

Communication is essential for coordinating activities and maintaining relationships among kin, mates, neighbours, and any other individuals that interact. Indeed, communication is a necessary and driving force behind the evolution of animal sociality. Our research on red squirrels investigates the information content of acoustic signals, which are critical for defending territories necessary for survival. We have shown, for example, that squirrels communicate kin status, individual identity, and stress state through subtle variations in call structure. This research is important because it identifies mechanisms that can mediate critical social interactions, including territorial disputes among neighbours and nepotistic behaviours among kin.

Dr. Nancy Chen

University of Rochester

My lab studies the evolution of natural populations on short timescales by combining evolutionary genomics with long-term demographic studies. In collaboration with the Kluane Red Squirrel Project, we plan on linking variation in individual genetic contributions over time to allele frequency dynamics across the genome. This system provides a valuable opportunity to study the effects of highly fluctuating vs. more stable environments on short-term evolution in natural populations with known ecological contexts.
