The Systematics and Evolution Group (SEG)

We are working with biological diversity in the broad sense. Our main interests are what processes contributes to observed biodiversity, what are the drivers and why is diversity lost. In our research, we discover, give names to, and classify new species (taxonomy), determine evolutionary relationships between organisms, and thus contribute to our common understanding of the tree of life and the history of life on Earth. We also study what processes cause new species to be formed, and what processes that explain the distribution and variety in different geographic regions around the world.

SEG consists of botanists and zoologists. We study different kinds of organisms, including vascular plants, insects, bryophytes, marine organisms, lichens – and humans. We use both morphological and molecular tools in this work, depending on study organism and the kinds of questions asked. We map species and collect them in nature, and use a range of laboratory analyses. We use genome analyses and advanced bioinformatics to gain detailed knowledge on biodiversity and the history of species.

We teach on all levels at the NTNU, both at bachelor level (including course in floristics, faunistics and biogeography), masters level (in collaboration with the Nordic NABiS network, Nordic Academy of Biodiversity Studies), and PhD level (including courses in collaboration with ForBio, the Norwegian Research School in Biosystematics). We offer many different kinds of master projects.
