Katriina Ilves's research focuses on the evolutionary and ecological processes responsible for generating aquatic biodiversity, with a particular focus on fishes. Using a broad toolkit that includes data from genetics, genomics, morphology, geology, climate, and museum collection databases, Katriina aims to address the interrelated questions about the what (species are present), why (are species found in some areas and not others), and when and how (did diversification occur) of biodiversity in disparate aquatic regions and biomes, such as Caribbean coral reefs, deep-sea Gulf of Mexico, and marine and freshwater habitats of the north temperate and Arctic (Holarctic). Understanding the processes responsible for historical evolution and community composition can also provide insight into the processes that affect species and their communities in today's changing world.
Current research projects include:
- Study of "species pairs" (ecologically, morphologically, and/or reproductively differentiated populations that may be sympatric at some point in their life cycle) of north temperate smelts in Ontario, Quebec and British Columbia, in Canada, and Washington, U.S.A.
- Exploration of deep-sea fish biodiversity of the western Atlantic Ocean and the Gulf of Mexico.
- Systematics and comparative phylogeography of Caribbean reef fishes.
- Documentation of changes in community composition of Caribbean and north temperate fishes resulting from anthropogenic disturbance using historical and contemporary museum collection data.
Katriina is also passionate about biodiversity education at all stages and is excited to continue museum-based outreach work and mentoring of undergraduate and graduate students at the Canadian Museum of Nature.
