PhD-student Susa Niiranen does research focusing on the Baltic Sea food web dynamics and their response to changes in environmental and anthropogenic forcing. Food web modeling is one of the main tools employed in this study. Her research is carried out within the framework of the Baltic BONUS-project ECOSUPPORT (Advanced modeling tool for scenarios of the Baltic Sea ecosystem to support decision making).In the upcoming seminar, Susa will present ongoing studies and a paper on the "Future climate projections provide insight into how the interaction of multiple drivers may affect the Baltic Sea food-web resilience", work where she collaborates with colleagues at the Baltic Nest Institute and the Dept. of Systems Ecology at the Stockholm University.Abstract:Multiple driver interactions are known to affect ecosystem resilience. We used the best available information about future climate, nutrient loads and fishery to study the Baltic Sea food-web resilience under possible future combinations of these drivers. Food-web projections were simulated for 2011-2100 using an Ecopath with Ecosim model of the Baltic Proper (BaltProWeb) that was run for two cod fishing, three nutrient load and two regional climate scenarios (corresponding to IPCC scenarios A1B and A2), in all combinations. The system was considered resilient when changes in climate promoted no food-web wide regime-shifts in future projections. Correspondingly, the lack of resilience was indirectly measured from regime-shift frequency and amplitude. These shifts were identified with the sequential regime-shift detection method STARS, applied on the first principal component of the PCA-analysis that compiles biomass information across the food-web. Based on the criteria used, the food-web was most resilient when both the cod fishing pressure and nutrient loads were low. These results suggest that regional actions, such as regulation of nutrient loads and fisheries, may be important in defining how vulnerable the Baltic Sea ecosystem is to changes in more global drivers. This was the first attempt to project the Baltic Sea food-web resilience to future climate change using the state-of-the art climate projections. We recognize that such modeling approaches involve large uncertainties, however, they are amongst the few tools that can provide long-term marine ecosystem planning with information about the ecosystem properties that may enhance ecosystem resilience under future conditions.

Vill vi att våra barn och barnbarn ska kunna bada och fiska i Östersjön? Då behöver vi visa politisk handlingskraft! Miljöfrågorna måste hanteras internationellt: luftföroreningar, kemikalier och avloppsvatten stannar inte vid nationsgränserna. Därför arrangerar Kristdemokraternas Europaparlamentariker ett seminarium där situationen i Östersjön ställs i centrum. Vad kan vi tillsammans i EU göra för att Östersjön ska vara ett levande innanhav?Medverkande:Alf Svensson - Europaparlamentariker för KristdemokraternaAnders Wijkman - miljödebattör och författare som talar under rubriken "Vårt beroende av haven"Fredrik Wulff - Professor i marin systemekologi på Stockholms Universitet som talar under rubriken: "Hur mår Östersjön? Hot och bot"Tid och PlatsDatum och tid: Måndagen den 12/11, kl 18:00-19:30Plats: Europahuset, Regeringsgatan 65, plan 2, StockholmAnmälan görs till

This seminar, Eutrophication and Agriculture: State of play, is co-organized by the HELCOM Agriculture and Environment Forum and Priority Areas 1 and 9 of the EU Strategy for the Baltic Sea Region (EU SBSR): Priority Area NUTRI (reducing nutrient inputs to the sea) and Priority Area AGRI (sustainable agriculture, forestry and fisheries). The seminar will focus on the possibilities of the EU Strategy for the Baltic Sea Region to help the agriculture sector reduce the discharge of nutrients into the Baltic Sea. BNI presentation on eutrophication status of the Baltic Bo Gustafsson, BNI Sweden, is invited to present state of the art knowledge on eutrophication and will give a presentation on "Eutrophication in the Baltic Sea. What is the present status in terms of combatting eutrophication, and how far have we come with the actions taken?".Back to back with bigger conference This seminar is held back-to-back with the bigger conference 'A greener agriculture for a bluer Baltic Sea' co-organized by BalticCOMPASS, Baltic Deal and Baltic Manure.

In a joint workshop arranged by Stockholm University together with the Pierre and Marie Curie University and Cornell University, hydrologists, biogeochemists and ecologists will meet to discuss watershed models and nutrient accounting tools.Goal of the workshopThe goal of the workshop is to bring together some 15-20 American (US, Canada) and European scientists to work toward new approaches to address temporal trends of nutrient and carbon fluxes, both retrospectively and into the future, and to further encourage linkage of different modeling approaches. One task of this workshop is to share ideas as to how the various accounting methods and models presently handle the above-mentioned issues and how the “lateral” models and the “vertical models” might be conceptually interlinked.

Several researchers from Stockholm Resilience Centre (SRC) and Baltic Nest Institute (BNI) are members of NorMER: the Nordic Centre for Research on Marine Ecosystems and Resources under Climate Change. NorMER is a Nordic Centre of Excellence that studies the biological, economic, and management consequences of global climate change on fisheries resources in Nordic seas, with a focus on the Atlantic cod (Gadus morhua). This cross-Nordic collaborative project started in 2011 and is funded over five years. Researchers from SRC/BNI participated during the 2nd annual meeting.The NorMER project (Nordic Centre for Research on Marine Ecosystems and Resources under Climate Change) holds its annual meeting in Helsinki 4-5 October.BNI participantsThe annual meeting took place at the University of Helsinki 4-5 October. Participating researchers from SRC/BNI were Johanna Yletyinen, Wijnand Boonstra and Thorsten Blenckner together with NorMERs co-chair Carl Folke, Scientific Director of the Stockholm Resilience Centre. Johanna has just started her PhD and presented her project plan about network analysis on climate effect on Baltic Sea food web from social-ecological system perspective, Wijnand presented a poster highlighting some preliminary results on Swedish fishing styles in the Baltic, and Thorsten participated in the NorMER management board.Science meets scienceAt the annual meeting PhD students and postdoctoral students from the different NorMER partners presented and discussed their work through speedtalks, Powerpoint presentations and slowtalks. The meeting also offered opportunities to informally discuss scientific results and to organize ongoing collaboration, as well as to initiate new research projects between the various researchers and institutes within NorMER. Facilitating interdisciplinary collaboration and education of young researchers is a key objective of NorMER. For this reason PhD and postdoctoral students organized a workshop after the annual meeting at Lammi, a field station north of Helsinki. The workshop was used to further strengthen ongoing research collaboration, but also to initiate some new research projects.The third annual NorMER meeting will be organized in Reykjavik (autumn 2013).
