Short overview with commentary from the invited lectures, students and course organizers.

Presentations by invited lecturers

1. Biogeochemical modeling in the Baltic Sea, RCO-SCOBI, future climate projections

Markus Meier, SMHI and Stockholm University

Markus Meier is a physical oceanographer with more than 20 years’ experience of numerical modeling of ocean circulation, sea-ice and marine biogeochemical cycles. He is the head of the oceanographic research unit at the Swedish Meteorological and Hydrological Institute in Norrköping and adjunct professor at Stockholm University. His recent research focuses on coupled physical-biogeochemical modeling of the Baltic Sea to study marine ecosystems in past and future climates. He has a particular interest in the assessment of uncertainties of regional climate change simulations using ensemble techniques.

2. Biogeochemical modeling in the Baltic Sea, BALTSEM model

Bärbel Müller-Karulis Baltic Nest Institute, Stockholm University Baltic Sea Centre

Bärbels main interest is the biogeochemical cycling of nutrients in the Baltic Sea. She has started with modeling the long-term dynamics of nutrients and phytoplankton in the Gulf of Riga and found that the balance between nitrogen and phosphorus pools is crucial for the structure of its pelagic ecosystem.

3. Modeling with multiple currencies – Ecological Stoichiometry

Tom Andersen, University of Oslo

I have a PhD in theoretical ecology from the University of Oslo (1993), and have been professor at the same institution since 2003, with focus on marine and limnetic food web ecology. With a background in biology, chemistry, statistics, and computer science, my main interest has been in applying ecological theory and mathematical methods in designing and analyzing food web experiments. Together with colleague Dag O. Hessen and international collaborators, I have been fortunate to take part in developing the research direction called Ecological Stoichiometry – the study of the balance of chemical elements in ecological interactions.

4. Key concepts in modelling the spatial distribution of fish

Benjamin Planque, Institute of Marine Research in Tromsø

Benjamin Planque holds a PhD from the University Pierre et Marie Curie (Paris, France, 1996). He did his PhD thesis on the spatial and temporal fluctuations of crustacean populations in the North Atlantic. His research has focused on zooplankton, ichtyoplankton and fish spatial and temporal variations in relation to environmental fluctuations and fishing. He currently holds a research position at the Institute of Marine Research in Tromsø where he works on the ecology of redfishes and coordinates the BarEcoRe project on the resilience of the Barents Sea ecosystem.

5. Application of quantile regressions to modelling spatial distributions

Benjamin Planque, Institute of Marine Research in Tromsø

6. Size-dependent population and community dynamics – models and Baltic Sea applications

Anna Gårdmark, Swedish University of Agricultural Sciences, SLU

Anna Gårdmark, senior research fellow at the Dept of Aquatic resources, Swedish University of Agricultural Sciences, studies ecological and evolutionary dynamics of marine food-webs using a range of statistical and dynamical modeling approaches. Her research is focused on how species interactions govern the responses of food-webs to exploitation as well as to environmental change. She is also engaged in advancing ecologically based advice for fisheries.

7. Evolutionary responses to fishing – examples and modelling approaches

Anna Gårdmark, Swedish University of Agricultural Sciences, SLU

Anna Gårdmark, senior research fellow at the Dept of Aquatic resources, Swedish University of Agricultural Sciences, studies ecological and evolutionary dynamics of marine food-webs using a range of statistical and dynamical modeling approaches. Her research is focused on how species interactions govern the responses of food-webs to exploitation as well as to environmental change.

8. Fisheries assessment models

Stefan Neuenfeldt, DTU Aqua, National Institute of Aquatic Resources

9. Trait-based models, ecological mechanics and marine ecosystems

Øyvind Fiksen, University of Bergen

I work on behaviour and strategies in fish, zooplankton and microbes, and on the consequences of these tactics and strategies in an ecosystem context. The aim is to develop ecological models where mass and energy fluxes are emerging from evolutionary consistent mechanisms – through natural selection. Read more about Øyvind.

10. Competition between fish and jellyfish

Øyvind Fiksen, University of Bergen

I work on behaviour and strategies in fish, zooplankton and microbes, and on the consequences of these tactics and strategies in an ecosystem context. The aim is to develop ecological models where mass and energy fluxes are emerging from evolutionary consistent mechanisms – through natural selection. Read more about Øyvind.

11. General additive models and their application in modelling zooplankton lifecycle dynamics

Saskia A. Otto, Stockholm Resilience Centre

Saskia Otto, postdoctoral researcher at the Stockholm Resilience Centre, Stockholm University, investigates within the BEAM program how population and ecosystem dynamics respond to climate, eutrophication and fishing. A strong focus hereby is the non-linearity and non-additivity of these responses. For this, she applies advanced statistical time-series analysis with threshold formulations. An additional aim is to contribute to an ecosystem-based management by providing thresholds and targets of ecosystem state indicators.
