Digweed, Shannon - MacEwan University - Department of Biological Sciences

个人简介

Dr. Digweed is a joint faculty member in the departments of Psychology and Biological Sciences. She received her PhD in Evolution and Behaviour from the University of Lethbridge, her Master of Arts from the University of Calgary and her Bachelor of Science from the University of Alberta. She teaches a variety of courses including, Animal Behaviour, Principles of Behaviour and Comparative Cognition. She has supervised a number of both honours and independent study students on projects related to acoustics and behaviour in red squirrels, wood frogs and domestic cattle. In addition to teaching, she is also actively involved in research, specifically in the areas of animal communication and behaviour. Dr. Digweed’s research explores how the acoustic or physical structure of animal sounds are shaped in important ways by their function. Early research focused on the production of predator specific vocalizations calls in white-faced capuchin and current research explores vocalizations in the North American red squirrel as well as mating calls of the common wood frog. A new field location is being established to explore vocalizations in American pika, a small member of the rabbit family that lives in high altitude habitat. Future research will continue to explore how the acoustic structure is shaped by function because currently there is only a rudimentary understanding of these structure-function relationships that are central to the organization of animal vocal signaling systems.
