Conservation, Natural History, Wildlife
This course will explore trophic cascades, important interactions between species that can affect an ecosystem in significant, and possibly unexpected, ways. Come investigate how wolf reintroduction, fluctuations of elk and bison numbers, and landscape changes have altered Yellowstone over the decades. Along the way, this course will investigate how these and other species of plants and animals have been changed with field trips and short classroom discussions to emphasize important concepts.
About the instructor
Brenna Cassidy was born and raised in northern Illinois where her curiosity for the natural world grew in the forests and tall grass prairies. She completed a degree in Wildlife Ecology at the University of Wisconsin-Stevens Point and spent summers during her undergraduate degree in northern Wisconsin and Yellowstone National Park. After graduating in 2012, she moved back to Yellowstone and worked on multiple projects studying birds, cougars, and wolves and spent five years seasonally migrating between the Bird Program and Wolf Project. Her Ph.D. research focuses on the survival and reproduction of gray wolves in Yellowstone National Park. While not working, she can be found trying her hand at most art forms and outdoor activities.
