1. Ecology across Boundaries : Food web coupling among and within ecosystems
Sammanfattning : 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.

2. 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
3. The influence of trophic polymorphisms on habitat coupling in aquatic food webs
Sammanfattning : Trophic cascades, together with other indirect interactions are important aspects in shaping the composition and abundance of species in the food web. Theoretically, movement of energy between systems, and coupling between habitats by mobile predators have been suggested as being important for food web stability and evenness. LÄS MER
4. Importance of blue mussels for biodiversity and ecosystem functioning in subtidal habitats
Sammanfattning : Blue mussels, Mytilus spp., occur on rocky and sedimentary shores worldwide where they often form dense aggregates. These assemblages change the local environment and create unique habitats. LÄS MER
5. Biomass patterns in boreal-subarctic lake food webs along gradients of light and nutrients
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
