Wolf genetics and ecology with Astrid Vik Stronen

03/04/25 • 58 min

In this episode, conservation biologist and genetics researcher Dr. Astrid Vik Stronen discusses her journey into wildlife research and conservation, beginning with her early passion for ecology and evolving into a focus on wildlife genetics and genomics.

From tracking wolves through the dense forests and rolling hills of Riding Mountain National Park, Manitoba to analysing hundreds of wolf scats collected in the coastal temperate rainforests of British Columbia, Astrid offers captivating insights and stories from both the field and the lab.

Delving into the fascinating world of conservation genetics, we explore an innovative and rapidly expanding field that enables researchers to track and understand wild animals, often with minimal disturbance. Astrid explains that by collecting hair, scats, and other genetic materials, we can create genetic profiles for individual animals, which allow us to assess relatedness among pack members, inbreeding levels, population structure, and even disease movement. She also emphasizes the critical need to preserve genetic diversity and understand how wolves and other wildlife are adapting to the challenges posed by human disturbance and rapid environmental change.

Dr. Astrid Vik Stronen is a wildlife biologist and researcher in conservation genetics and ecology, primarily working on wolves and other larger carnivores. Recent research projects include genomic analyses of wild species and threatened domestic breeds in Europe and Canada, including wolves, golden jackals, bears, European bison, Mediterranean monk seals, and native cattle and dog breeds at risk.

Astrid is interested in contemporary evolution resulting from human activities, and how we can best preserve wild species and their habitats in the face of rapid environmental change. She also has a strong interest in applied conservation genetics, and in projects that integrate ecology, evolution, and conservation and connect these fields to human dimensions including ethics and human-wildlife interactions.

Since 2018, Astrid has been living and working in Ljubljana, Slovenia, as part of the “ekozivali” (animal ecology) group at the University of Ljubljana’s Biotechnical Faculty, and she is also a co-founder and researcher at the Biotechnical Faculty’s spin-out company DivjaLabs. During the past years she has had the chance to participate in several research and conservation projects in Slovenia and beyond, and she appreciates the opportunities to continue to get to know this beautiful and biodiverse region.

The science and ethics of tracking wolves with Shelley Alexander

In this episode, wildlife scientist and canid specialist Dr. Shelley Alexander shares captivating stories and insights from the early days of her wildlife career. From tracking the return of wolves in Banff National Park to raising coyote pups and working with livestock owners, Shelley reflects on how these formative experiences have influenced the trajectory of her work 25 years later.

Challenging the traditional concept of habitat, we explore how animals might experience habitat alteration and loss, emphasizing the importance of considering not only the physical attributes but also the cognitive and affective landscape of “good” habitat.

Acknowledging the inextricable link between science and ethics, we delve into the ethical considerations of trapping and collaring wolves for research. We also explore the broader ethical, ecological, and social implications of the indiscriminate and targeted killing of wolves and other canid species.

Dr. Shelley Alexander is a Professor of Geography at the University of Calgary. She has over 30 years of experience studying human-wildlife coexistence, specializing in wolves and coyotes. She founded the Canid Conservation Science Lab, embracing non-invasive methods and the principles of Compassionate Conservation.

Shelley started her wildlife career in 1991 as a field researcher working for Dr. Paul Paquet on the first study of recolonizing wolves in Banff National Park, Canada. She also studied briefly with Dr. Jenny Ryon (Dalhousie University) monitoring captive wolf family dynamics, in-den behaviour, and play in coyote pups.

Shelley became an international expert in road ecology and geospatial analysis for carnivore conservation. Since 2006, she has led the Foothills Coyote Initiative, investigating topics from coyote ecology and social intelligence to human-coyote conflict and the effects of urbanization on coyotes, landowner experiences with and media portrayal of coyotes, spatial epidemiology, and the intersection of colonial ideology, ethics, and coyote killing. She also created UCalgary Living with Wildlife — an active evidence-based wildlife coexistence program on campus.

In November 2024, Shelley was elected to the College of Fellows of the Royal Canadian Geographical Society, recognizing her contributions to raising the profile of Canada's natural heritage at home and worldwide.

Wolf research and conservation with Chelsea Greer

In this episode, Wolf Conservation Program Director and podcast host Chelsea Greer reflects on her early fascination with the human-animal bond and how her post-secondary education transformed her perspective on what truly benefits wildlife. She discusses how exploring alternative paradigms to traditional conservation and animal welfare science sparked her curiosity about applying animal welfare principles to wildlife and developing creative coexistence strategies.

From studying elephants in Thailand to protecting wolves in British Columbia, Chelsea shares how her time as a graduate student in the Canid Conservation Science Lab at the University of Calgary deepened her understanding of the challenges facing wolves and coyotes in North America, ultimately leading her to Raincoast to help develop the Wolf Conservation Program. Working as a biologist and wolf researcher within the program, Chelsea also recounts her first encounter with a wolf in the wild, reflecting on the layers of meaning behind the experience and the actions it inspired.

Guided by the inextricable link of science and ethics, Chelsea emphasizes how Raincoast’s approach to wildlife conservation continues to be grounded in doing the most good and the least harm to people, animals, and the environment. We delve into the importance of wolves and wolf conservation, highlighting not only the profound role wolves play in ecosystems, but also the cultural and intrinsic value they hold both as a species and as individuals.

Finally, Chelsea reflects on what she has learned from interviewing this remarkable group of women and what studying wolves has taught her about herself.

Chelsea Greer is the director of the Wolf Conservation Program at Raincoast Conservation Foundation. The focus of her work is to support the protection and conservation of wolves in British Columbia through peer-reviewed research, community partnerships, public education, and wildlife management reform. This includes scientific and ethics-driven initiatives that are working toward the implementation of provincial policy that respects the welfare of wolves and their important role in functioning ecosystems.

Chelsea is particularly interested in the welfare concerns that arise from the lethal management of predators and is an advocate for animal welfare in scientific research. Her research interests also include better understanding predator-prey dynamics in salmon-bearing watersheds and the role wolves play in biodiversity conservation and ecosystem resilience.

Chelsea completed her master’s degree in Geography at the University of Calgary where she studied the behavioural ecology of rewilded Asian elephants in northern Thailand. Her graduate research used a compassionate model of conservation to investigate the rehabilitative and ecological requisites of elephants transitioning from captive to free-living settings. Chelsea also holds a bachelor’s degree from the University of British Columbia where she majored in Applied Animal Biology. It was during this degree that she developed a keen interest in animal ethics and how animal welfare science applies to free-living wild populations.
