1. 1. Studies of Baltic Sea plankton - spatial and temporal patterns

   Författare :Helena Höglander; Ulf Larsson; Christoph Humborg; Anna-Stiina Heiskanen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytoplankton; Vertical distribution; Sedimentation; Baltic Sea; Cyanobacteria; Stable istopes; Cercopagis pengoi; Zooplankton; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Sammanfattning : This thesis examines the spatial and temporal patterns of Baltic Sea phyto- and zooplankton. Studies of such patterns are important to gain a better understanding of the offshore nutrient dynamics of the Baltic Sea (Papers I and II) and how to manage eutrophication and invasive species in coastal areas (Papers III and IV).

   Sammanfattning : In this thesis natural science is combined with environmental psychology in order to determine how deforestation and subsequent agricultural expansion in the Peruvian highland jungle has affected the natural environment and rural livelihoods. This region is part of one of the most biodiverse areas on Earth and is also exposed to high pressure from deforestation that threatens the ecosystems as well as the well-being of local populations.

7. 5. Makten över regionen : En idékritisk studie av svensk regiondebatt 1963–1996

   Sammanfattning : Who should exercise power over the region? A governor appointed by the central state, a directly elected regional assembly or municipalities in co-operation? For almost four decades this has been a highly contested issue in Swedish decision-making bodies as well as in editorial pages. Not least in the 1990s, as Sweden has got closer to the intensified process of European integration, has the regional question been an important subject on the political agenda. LÄS MER
