Undervisning

I have broad experience of teaching as a lecturer/senior lecturer, course leader and teaching assistant on University level in many different subjects and topics, e.g. general ecology, marine ecology, conservation biology, sustainable development and sustainable use/management of natural resources, experimental design, biological complexity, and environmental monitoring at different levels (undergraduate to graduate level) and at many different Universities.

Forskning

I am presently working as a researcher within the DCF-project at Institute of Coastal Research led by Zeynep Pekcan-Hekim. My work involves mainly the spatial variability and heterogeneity (spatial structure) of length and age distributions of flounder over time in the Baltic, and temporal variability and heterogeneity of herring (Bothnian Sea and Bothnian Bay), which both have implications for management.

As a researcher in marine ecology my main emphasis has been on intertidal ecology, especially rocky shores, but also to some extent soft-bottom and subtidal habitats (mussel- and seagrass systems). I have worked with different organisms and questions, but lately my research interests include:

  • Spatial and landscape ecology (mainly using semivariogram and fractal analyses)
  • Habitat loss & fragmentation; their effects on diversity & abundance of organisms
  • Habitat amount threshold effects on associated intertidal and subtidal organisms
  • Recruitment patterns and sustainability of exploited mussels
  • Effects of distance to & size of MPAs on colonisation of exploited coastal species
  • Interactions between co-existing invasive and indigenous mussels in South Africa
  • Effects of habitat complexity on biodiversity and abundance of organisms
  • Management of coastal ecosystems

 

Some recent research projects:

Sustainability of exploited and invaded indigenous mussels along the coast of South Africa: recruitment and restoration of populations (Funding from Formas and SIDA/Sarec, Sweden)

Effects of habitat loss and fragmentation on biodiversity, abundance and population processes of macrofauna using mussel beds as a model system (Funding from Formas)

Connectivity between protected and exploited South African mussel communities: effects of size and proximity of Marine Protected Areas, and the role of mussel bed rehabilitation (Funding from The Swedish Research Council and SIDA/Sarec, Sweden)

Ecosystem effects of the establishment of cormorant colonies in the Gulf of Finland (Funding from Svenska Kulturfonden, Finland; Collaboration with Mats Westerbom, Eliecer Diaz, Mikael Kilpi, Markus Öst)

Bakgrund

I have a background mainly as a researcher in marine ecology, conservation biology, sustainable resource use and management. Recently I also worked as a marine ecologist at Vattenmyndigheterna and Länsstyrelsen in Göteborg. I worked with management of water bodies (Vattenförvaltning), especially coastal zone management applying both the Water Framework Directive (vattendirektivet) and the Marine Strategy Framework Directive (havsmiljödirektivet), planning environmental monitoring programs nationally and regionally, especially along the west coast of Sweden, and participating in national work groups.

Handledning

I have been the main supervisor for one PhD-student and 4 MSc-students at Åbo Akademi University and Stockholm University. I have been a co-supervisor for 6 PhD- and MSc-students, and the mentor and employer for a post-doctoral researcher within my Formas-project.
