Why Study Ecology at U of G?

Ecology combines the best of many worlds, including biology, environmental sciences and geology, to better understand the relationships organisms have with their environments.

 A Growing, Multidisciplinary Field

How do plants, animals, and microbes interact with their surroundings? Through field-based work and theoretical knowledge, explore how humans help and hinder these connections. Ecology draws on many other fields, including biology, environmental sciences and geology.

 Understand Broad Ecological Topics

Our faculty work in both land and aquatic ecosystems on a broad range of topics, including how organisms respond to changing environmental conditions, the structure and dynamics of populations and communities, and ecosystems processes.

 Go Beyond the Classroom

Immerse yourself in great field courses taking you to Algonquin Park, Churchill, Man., Nova Scotia and more, and make use of incredible research facilities on campus, such as the Phytotron and Hagen Aqualab.

The Ecology program is a great way to better understand the world around you. By taking various classes such as ecology, natural resource economics, and molecular biology, the program allows you to understand the complexity of the environment from a more holistic perspective. Co-op allowed me to put what I learned in class to practical use and learn from people in the environmental field. You can also customize your upper-year degree to focus on your interests!

Choosing Ecology at the University of Guelph has been one of the best choices I have made! Many courses within the program have provided me with meaningful hands-on experience through fieldwork and data analysis, which has helped accelerate my career as an ecologist. Additionally, the Ecology program has a strong sense of community, which has provided me with lifelong friendships and invaluable connections. I would wholeheartedly recommend this program to anyone who would like to make a difference in our environment!
