Environmental and Marine Biology – research and researchers

Environmental and Marine Biology – research and researchers

Our research is primarily focused on marine biology, ecology, behavioural and evolutionary ecology and environmental topics. Within behavioural and evolutionary ecology we are primarily interested in reproductive behaviour and the evolution of signals and cryptic coloration.

During the last decades the environmental problems caused by human activities in the Baltic Sea have escalated. Signs of radically changing marine ecosystems are becoming more and more obvious, even to the public, trough e.g. cyanobacterial blooms. The research on the department of Environmental and Marine Biology is mainly focused on coastal waters and environmental problems in the Baltic Sea, where many projects are carried out on the Åland Islands and in the Arcipelago Sea. Major reserach themes are among other things eutrophication, biodiversity, biogeography of plants and birds in archipelagos, algae and shallow bays.


Research staff

Erik Bonsdorff, Professor of Marine Biology

My research interests include marine ecological and environmental aspects of the Baltic Sea (with focus on coastal and archipelago waters), including zoobenthos, fish, macroalgae, food web dynamics, biodiversity, long-term changes, experimental analysis of biotic interactions, and environmental stress of the Baltic Sea ecosystem. My work also includes interdisciplinary and applied aspects with transfer of knowledge and advice for management, governance and policy-aspects of the Baltic Sea environment (national and international).

Kai Lindström, Professor in Ecology and Environmental Sciences

One of the main objectives of my research is to explore the interaction between life history and sexual selection using fish as model organisms, but also to extend these questions into more applied issues.

Christoffer Boström, Associate Professor, Docent in ecology of marine communities

My research is focused on benthic ecology, in particular structure and function of seagrass ecosystems. I am interested in which factors regulate growth and dynamics of submerged aquatic vegetation at different spatial and temporal scales and across interlinked biological hierarchies.

Maria Laamanen, affiliate professor in marine environmental research

Tom Wiklund, Senior Lecturer in Biology, Docent in fish pathology, Head of Laboratory of Aquatic pathobiology

Bacteriophage based technology for pathogen control in aquaculture

Markus Öst, Senior Lecturer

Environmental stress puts pressure on species adaptation. Our main study system are eiders from the Baltic Sea; we use a long-studied (> 25 yrs) population from Tvärminne, SW Finland.

Mikael von Numers, University Teacher

  • Long term changes in the flora and bird fauna of the Archipelago Sea and causes to these.
  • Modeling of distribution patterns of birds and vascular plants.

Marie Nordström, Senior Research Associate in Marine Biology, Docent in marine food web ecology

I am a Senior Researcher studying marine food webs and benthic communities. I am interested in trophic interactions, particularly relating to the coupling between biodiversity and ecosystem functioning, and I am using a number of different coastal ecosystems (Baltic Sea, French Atlantic coast, NE Greenland) in my assessments of network structure and trophic processes under environmental change. See also personal website.

Sonja Salovius-Lauren, Senior Research Associate

In the national VELMU-program, information about different nature types and species diversity in the marine underwater nature is gathered. Based on mathematical modeling of biological, geological and physical field data, we aim at producing thematic maps and other information from the Finnish sea areas.

Martin Snickars, Senior Lecturer, Head of Husö Biological station, docent i kustvattenekologi

Key words/main interests:
Ecology and function of shallow coastal waters, interaction among juvenile fish and between fish, zoobenthos and abiotic factors, eutrophication and climate effects on predator-prey interactions, Marine Spatial Planning, including habitat mapping and distribution of sea uses (e.g conservation interests and vulnerability).

Katri Aarnio, amanuensis

  • meiofauna ecology
  • biotic interactions in shallow archipelago areas
  • food webs: meiofauna -> higher trophic levels
  • eutrophication
