21. Microbenthos under Pressure : Impacts of human activities on bacteria and meiofauna communities in Baltic soft sediments
Abstract : The marine benthic zone is one of the largest habitats on the planet, harbouring a large diversity of life that underpin many important ecological processes. However, these habitats have been under growing stress from human activities, profoundly altering their living communities. READ MORE

22. Effects of warming on the ecology of algal-dominated phytobenthic communities in the Baltic Sea
Abstract : Through climate change, the global average air and surface water temperature has risen 0.85°C during the last 100 years. The Baltic Sea experienced one of the most rapid increase in temperature recorded of marine ecosystems. READ MORE

23. Ecology of zooplankton communities: climate, dormancy, and benthic-pelagic coupling
Abstract : This thesis describes how influences, such as top down and bottom up forces, shape zooplankton communities in shallow lakes. I have also extended the traditional food-web theory by investigating the effects of climate on total biomass, taxonomic composition, and temporal properties of zooplankton communities. READ MORE

24. Assessing Sub-Lethal Impacts of Petroleum Compounds on Marine Benthic Systems
Abstract : Petroleum and its different distillates commonly end up in the marine environment. One source of these additions is discharges originating from shipping activities; accidents, ship wrecks, operational spills etc. READ MORE

25. Nutrient Stoichiometry in Benthic Food Webs – Interactions Between Algae, Herbivores and Fish
Abstract : The aim of this thesis was to identify general structuring mechanisms in benthic food webs within the framework of ecological stoichiometry theory. Ecological stoichiometry is defined as the balance of multiple chemical substances in ecological interactions and explicitly considers the combined dynamics of key elements such as carbon (C), nitrogen (N) and phosphorus (P).
