1. Baltic shore-lands facing climate change
Abstract : This thesis provides new insight concerning drivers behind differences in arthropod diversity and abundance in Baltic shore ecosystems and how the arthropod communities might be affected when the conditions in the Baltic Sea are altered due to climate change. The focus has been on climate related changes that are unique for coastal ecosystems, especially sea level rise and changes in the inflow of marine nutrients. READ MORE

2. The Spider and the Sea : Effects of marine subsidies on the role of spiders in terrestrial food webs
Abstract : The purpose of this study was to identify if terrestrial arthropod predators on Baltic Sea shores vary in their use of marine versus terrestrial food items, and to construct a bottom-up food web for Baltic Sea shores. The inflow of marine nutrients in the area consists mainly of marine algal detritus and emerging aquatic insects (e.g. READ MORE

3. Ecology across Boundaries : Food web coupling among and within ecosystems
Abstract : Cross-boundary movements of energy and material are ubiquitous. Freshwater ecosystems receive nutrients, dissolved, and particulate organic matter from adjacent terrestrial ecosystems, whereas terrestrial ecosystems mainly receive prey organisms and detritus deposited by physical processes such as floods from freshwater ecosystems.

4. Connections between biodiversity and ecosystem functioning in large-scale natural ecosystems
Abstract : Billions of years of evolution have given us a planet that supports a remarkable diversity of life. Estimates for the number of Eukaryotic species frequently number in the millions and the Prokaryotes are much more diverse than that. This biodiversity makes up the ecosystems that we, as humans, rely on to sustain almost every aspect of our lives. READ MORE

5. Fish Community Structure and the Role of Non-Indigenous Species Associated to Seagrass Ecosystems of Eastern Mediterranean
Abstract : Temporal and spatial variation in density, biomass and body size of littoral fish species associated with near shore Posidonia oceanica meadows were studied throughout an annual cycle in an area of eastern Mediterranean. Approximately 109350 littoral fish were collected, belonging to 34 families and 88 species. READ MORE
