Small mammals are central to Northern ecosystems and their fluctuations in abundance, whether cyclical or irregular, lead to pulsations of biodiversity. Dominique tries to elucidate the mechanisms of these fluctuations through empirical studies using field observations and museum collections.

Dominique Fauteux's research aims to better understand the workings of terrestrial ecosystems using micro-mammals. Animals in this group of species have often been identified as key players because of their central role in food webs and terrestrial food chains.

A brown lemming (Lemmus trimucronatus) on the tundra, Bylot Island, Nunavut.

Trophic interactions and the workings of northern ecosystems are greatly affected by the abundance cycles of lemmings and northern voles. Dominique's work consists mainly in following the changes in the abundances of micro-mammals and in determining the causes and consequences of these fluctuations. By combining work in the Arctic tundra and the thousands of specimens available in museum collections, Dominique will be able to provide insight into the mechanisms leading to various population dynamics in the Arctic and develop osteological tools to quantify the exchange of biomass between prey and predators (e.g., bones in the regurgitation pellets of prey birds). He will also be able to facilitate the identification of morphologically simian micromammals, and to understand if and how small mammals will adapt to a rapidly warming Arctic.
