Where Are They Now?

Back in 2005, Sarah Trefry was an award-winning undergrad at the University of Alberta. Much has changed since.

The award was the Ian Ross Memorial scholarship from the ACTWS. Soon, she completed her BSc, her MSc (vocalization in collared pikas) at U Alberta, and her PhD studying magnificent frigatebirds at UNB. Pretty big changes.

Sarah, now Sarah Hudson, has moved west to become the Marine Research Coordinator and Wildlife Biologist for Environment Canada in Delta, B.C. Her career has taken her from the Arctic to the tropics, coast to coast, furred to feathered, mountains to marine. The only thing that hasn’t changed is her award-winning work. Congrats Sarah.

“Rooted in Wisdom: Deer Aging Techniques”

Embark on a journey of precision and insight with the Lethbridge College Wildlife Analytics Lab (WAL) at the ACTWS Conference in Jasper! Join our workshop, ‘Rooted in Wisdom: Deer Aging Techniques‘, to explore the secrets hidden within wildlife teeth. Explore both the field technique of ‘tooth eruption and wear’ and the laboratory marvel of ‘cementum analysis’ – both dedicated to unraveling the mysteries of ungulate ages. Delve into the heart of these techniques, comparing their accuracy and precision, with a revelation of the superior accuracy of cementum analysis. Learn the art of tooth extraction and witness the seamless process of submitting your own wildlife teeth to the WAL for aging through cementum analysis. Elevate your understanding of deer populations and contribute to the advancement of wildlife knowledge and bolster your resume with applied experience. Participants will gain hands-on familiarity with the field technique of jaw aging, and the lab process of tooth extraction, inspection, preparation, and cementum analysis. Join us in Jasper for a transformative experience at the intersection of field expertise and cutting-edge laboratory analysis!
