Chiver's Lab (University of Saskatchewan)

I have exciting and innovative research program aimed at understanding the behavioural and cognitive ecology of risk assessment in aquatic animals including how anthropogenic changes influence the way animals respond to risk. My research focuses on  how animals change their behaviour, morphology and life history to deal with temporal fluctuations in risk and how the certainty of information, often chemical in nature, alters how prey respond to risk. We are at the forefront of understanding learning and memory in the context of predation. With a thorough understanding of the cognitive ecology of predator-prey systems, we attempt to identify how environmental stressors influence cognition, behaviour and ultimately survival in the wild. My students and I work on fishes and amphibians in a variety of freshwater and marine systems.


Manzon Lab (University of Regina)

My research group studies how fish and other vertebrates respond to changes in their internal and external environments with an emphasis on physiology and development. The aim is to understand how environmental changes modulate endocrine (hormone) physiology, metabolism and stress responses and how these in turn affect performance, survival and major developmental events. Our research is multidisciplinary and integrative in nature and we use tools within the fields of physiology, protein biochemistry, and molecular and cellular biology.  The ultimate goal is to understand processes in the whole organism and how these impact animals in their natural environment.



Somers Biology Lab (University of Regina)

My research uses a combination of field biology, molecular genetics, and stable isotopes to better understand interactions between humans and wildlife, and how animals respond to human-modified environments. In particular, my recent program has focused on: (1) understanding animal resource needs; (2) population structure; and (3) conflicts over fisheries resources. My group uses biotelemetry (radio and acoustic technologies) to study fish movements (walleye and sauger) after catch and release. I develop and use genetic markers to examine the population structure of several animal taxa, including birds (e.g., American white pelican, Sprague’s pipit), invertebrates (e.g., earthworms, tapeworms) and fish (e.g., walleye, sauger, lake whitefish, round whitefish). Recent projects have also used stable isotopes to augment our knowledge on population structure based on resource use, providing a novel perspective for management.  Ultimately my goal is to provide informative data to help develop and implement appropriate, science-based conservation and management strategies for the taxa I study.
