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
Sammanfattning : Changing abiotic factors, like temperature and light are important drivers of seasonality, affecting aquatic ecosystems and organisms annually in a predictable pattern, structuring species composition, growth, reproduction and trophic interactions. As a consequence of human induced climate change, coastal ecosystems are seeing a disruption in the predictability of annual cycles. LÄS MER
Sammanfattning : 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. LÄS MER
Sammanfattning : There is large natural variation in light and nutrient conditions across lakes. In the boreal-subarctic region most lakes are small, shallow and nutrient poor. In such lakes there is often sufficient light to support primary production at the lake bottom. LÄS MER
5. Benthic use of phytoplankton blooms: uptake, burial and biodiversity effects in a species-poor system
Sammanfattning : Animals living in marine sediments (the second largest habitat on earth) play a major role in global biogeochemical cycling. By feeding on organic matter from settled phytoplankton blooms they produce food for higher trophic levels and nutrients that can fuel primary production. LÄS MER
