Ecology of bacteria and viruses

At Marine Biological Section we study the ecology of marine viruses and their bacterial hosts the marine environment. Marine viruses are intracellular parasites of mainly heterotrophic bacteria, cyanobacteria and phytoplankton. Viruses are the most abundant biological components in the marine environment, and are often found at densities of >10E7 viruses per ml of seawater or per cmof sediment.

Viruses are important components in marine ecosystems and play significant roles in structuring the marine food web and cycling of carbon and nutrients in the oceans. We investigate these aspects of viral activity from field studies and by experimental studies of virus-host interactions under controlled conditions in the laboratory.

The Virus Group currently consists of 16 people ( docs, PhD students, MSc students and BSc students) working on a number of different research projects. Some of us appear on the recent group photo below. See a description of the group members on the "People" link.
