Poster Profile – Kaegan Finn

This month’s poster profile shares the work of Kaegan Finn, a University of Alberta student examining parasites in fish and 15N.

Poster title: Cestode Parasites are Depleted in 15N Relative to their Fish Hosts (pdf of the poster here).

Cestode parasites inhabit the bodies of many freshwater fish throughout Alberta. Including these parasites in food webs and associated research is necessary to accurately reflect ecosystem complexity. In his research, Kaegan, examined how the stable isotopes 15N and 13C differ between parasites and their hosts. Kaegan collected 92 host-parasite pairs across 7 species and 3 lakes in northern Alberta. Fish species included Spottail Shiner, Fathead Minnow, and Lake Chub. Results showed that 15N differed significantly between hosts and parasites. 13C did not differ between hosts and parasites but did vary among fish species. Results were similar to previous research and may support the adaptation of a standard discrimination factor for 15N, thus facilitating the inclusion of parasites in future food-web studies.

Kaegan’s poster is a great example of using graphics to complement text on a poster. Well done Kaegan!

Kaegan is an undergraduate student at the University of Alberta studying Environmental and Conservation Sciences. Kaegan currently works as a hydrometric technician for the Southern Rockies Watershed Project in the Crowsnest Pass and Waterton Lakes National Park. Kaegan is planning to pursue an MSc in early 2021 and is looking forward to a career in the world of wildlife and ecology.

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!
