- Ecosystem-based management requires understanding of food webs. Consequently, assessment of food web status is mandatory according to the European Union’s Marine Strategy Framework Directive (MSFD) for EU Member States. However, how to best monitor and assess food webs in practise has proven a challenging question. Here, we review and assess the current status of food web indicators and food web models, and discuss whether the models can help addressing current shortcomings of indicator-based food web assessments, using the Baltic Sea as an example region. We show that although the MSFD food web assessment was designed to use food web indicators alone, they are currently poorly fit for the purpose, because they lack interconnectivity of trophic guilds. We then argue that the multiple food web models published for this region have a high potential to provide additional coherence to the definition of good environmental status, the evaluation of uncertainties, and estimates for unsampled indicator values, but we also identify current limitations that stand in the way of more formal implementation of this approach. We close with a discussion of which current models have the best capacity for this purpose in the Baltic Sea, and of the way forward towards the combination of measurable indicators and modelling approaches in food web assessments.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this review was to review research addressing the relationship between population drinking and health, particularly mortality. The review is based primarily on articles published in international journals after 1994 to February 2005, identified via Medline. The method used in most studies is time-series analysis based on autoregressive intergrated moving average (ARIMA) modelling. The outcome measures covered included the following mortality indicators: mortality from liver cirrhosis and other alcohol-related diseases, accident mortality, suicide, homicide, ischaemic heart disease (IHD) mortality and all-cause mortality. The study countries included most of the EU member states as of 1995 (14 countries), Canada and the United States. For Eastern Europe there was only scanty evidence. The study period was in most cases the post-war period. There was a statistically significant relationship between per capita consumption and mortality from liver cirrhosis and other alcohol-related diseases in all countries. In about half the countries, there was a significant relationship between consumption, on one hand, and mortality from accidents and homicide as well as all-cause mortality on the other hand. A link between alcohol and suicide was found in all regions except for mid- and southern Europe. There was no systematic link between consumption and IHD mortality. Overall, a 1-litre increase in per capita consumption was associated with a stronger effect in northern Europe and Canada than in mid- and southern Europe. Research during the past decade has strengthened the notion of a relationship between population drinking and alcohol-related harm. At the same time, the marked regional variation in the magnitude of this relationship suggests the importance of drinking patterns for modifying the impact of alcohol. By and large, there was little evidence for any cardioprotective effect at the population level. It is a challenge for future research to reconcile this outcome with the findings from observational studies, most of which suggest a protective effect of moderate drinking.

Forskningsöversikt (refereegranskat)abstract
- Social-ecological systems dependent on fisheries must be resilient or adapt to remain viable in the face of change. Here, we identified possible interventions (termed “adaptation options”) from published literature, aimed at supporting social or ecological resilience and/or aiding adaptation to changes induced by environmental or social stressors. Our searches centered on nations/regions across North America, Europe, and the South Pacific, encompassing fisheries literature with and without a climate change focus, to compare how, when, and by whom interventions are currently or potentially implemented. We expected that adaptation options within a climate change context would have a greater focus on enhancing social resilience due to a connection with climate change adaptation assessment methodology. Instead, we found a greater focus on ecological resilience, likely indicating a focus on management adaptation. This pattern, along with the more extensive use of social adaptation options responsively and outside the context of climate change, along with an importance in bottom-up influences in implementing them, suggests a general lack of centralized planning and organization with regards to adaptation of stakeholders. Determining how adaptation options are created, chosen, and implemented is a crucial step within or external to ecosystem-based management, especially if planned stakeholder adaption is the goal.
