Most pelagic organisms rely on chemical stimuli to communicate and perceive their surroundings. This chemical “language” is largely unknown.
We target the individual signaling compounds and translate their function in the pelagic ecosystem.
We perform hypothesis driven research in pelagic chemical ecology. We isolate and identify signal molecules, explore how they are transmitted, what effect they have in the responding organisms and in the pelagic ecosystem.
The group is multidisciplinary, chemists and biologists work together on the same research questions.
Diurnal migration sampling with RV Skaggerak
Our most recent field trip involved a 24 hour sampling of the vertical migration pattern of copepods in Gullmarsfjorden just north of Gothenburg. Zooplankton samples and copepodamide concentrations are one part of master student Henrik Möllers thesis work.

A selection of photos and films documenting our work and findings with pelagic organisms.
Much of our work involves image and film analysis to better understand the behavioural response to chemical stimulae of the organims we study. Here we present our best photos and film, showcasing the beauty and complexity of this poorly understood ecosystem.
We regularly publish our findings in a variety of journals. The links to the right will take you to an external open access page where you can read the relevant article.
We primarily publish our findings through journals with a focus/interest in chemical ecology, microbiology and molecular biology.
