His current research is in food-web analysis and modeling of the Baltic Sea ecosystem. This includes identifying factors (e.g. overfishing, salinity, climate, alien species) which trigger regime shifts of the Baltic Sea ecosystem. He is also involved in the ICES Working Group on Integrated Assessments of the Baltic Sea.
He has experiences in field sampling (physical to biological parameters), quantitative experiments (large-scale mesocosm), laboratory (background lab technician), long-term statistical data analysis and ecosystem modeling (mass-balance).
Blenckner has presented his work at several international conferences and is an Associate Editor for the journal Marine and Freshwater Research. He has written several articles and co-authored a number of book chapters including a chapter for the Assessment of Climate Change for the Baltic Sea basin (Springer 2008).

How humans matter for ecological regime shifts
2019 - Journal / article
Ecosystem-based management (EBM) is commonly applied to achieve sustainable use of marine resources. For EBM, regular ecosystem-wide assessments of changes in environmental or ecological status are essential components, as well as assessments of the effects of management measures. Assessments are typically carried out using indicators. A major challenge for the usage of indicators in EBM is trophic interactions as these may in...

A major challenge in environmental modeling is to identify structural changes in the ecosystem across time, i.e., changes in the underlying process that generates the data. In this paper, we analyze the Baltic Sea food web in order to 1) examine potential unobserved processes that could affect the ecosystem and 2) make predictions on some variables of interest. To do so, dynamic Bayesian networks with different setups of hidd...

Sustainable fisheries management plays a critical role in supporting healthy marine ecosystems and the livelihoods of millions of people. An emerging view on fisheries management emphasizes the need to manage fisheries as complex social-ecological systems. Yet, our understanding of the outcomes of fisheries management from a social-ecological perspective is limited in comparison to that provided by either the biophysical or t...

Ecosystems often shift abruptly and dramatically between different regimes in response to human or natural disturbances. When ecosystems tip from one regime to another, the suite of available ecosystem benefits changes, impacting the stakeholders who rely on these benefits. These changes often create some groups who stand to incur large losses if an ecosystem returns to a previous regime. When the participation cost in the dec...
