1. Benthic-pelagic coupling in a changing world : Structural and functional responses of microbenthic communities to organic matter settling
Sammanfattning : Marine soft sediments form the second largest habitat on the planet. Organisms residing in this environment represent a vast reservoir of biodiversity, and play key roles in ecosystem processes. LÄS MER
2. Processes and factors governing benthic community dynamics—environmental change in the Baltic Sea
Sammanfattning : As drivers of biogeochemical cycles and nutrient recycling, such as carbon turnover, the microbial community is essential in sustaining functioning ecosystems. Together with the metazoan community, the microbial community constitute the majority of all life in the benthos. LÄS MER
3. Effects of community- and government-managed marine protected areas on tropical seagrass and coral communities
Sammanfattning : Tropical seagrass beds and coral reefs are among the most productive and diverse ecosystems on Earth and provide ecosystem services, such as fish production and coastal protection, and support livelihoods of millions of people. At the same time, these ecosystems are threatened globally by anthropogenic disturbances, such as overfishing, pollution and global warming. LÄS MER
4. The importance of predation in benthic stream communities
Sammanfattning : There has been considerable debate whether or not predators has any significant effects on prey densities in streams. This thesis examines the importance of predation in stream communities. I have conducted both field and laboratory studies where I have studied how both vertebrate and invertebrate predators affects benthic prey. LÄS MER
5. Climate change impacts on aquatic consumer communities
Sammanfattning : Climate change represents a serious threat to aquatic ecosystems, with an increase in lake temperatures already observed that is expected to continue in the near future. Aside from the direct effects of warming, climate change is also partially responsible for the browning of lakes. LÄS MER
