1. Ecological and evolutionary assembly processes and metacommunity structure
Sammanfattning : This thesis aims to elucidate the link between abiotic and biotic effects and biogeographical contingencies, eco-evolutionary assembly processes, and community structure in a spatially explicit metacommunity framework. To this end, we used structure analysis of naturally sampled and experimentally manipulated marine bacterial communities and mathematical eco-evolutionary modeling and simulations of metacommunity assembly.

2. 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
3. Food web dynamics in open and closed systems
Sammanfattning : This thesis is a summary of enclosure and microcosm experiments that aimed to study the impact of allochtonous subsidies on food web dynamics in a heterogeneous food web. In the enclosure studies, a three trophic level littoral food web was used. LÄS MER
4. Traits or species – space or environment : how to understand the spatial structure of springtail community composition
Sammanfattning : How communities are structured and the processes shaping species composition are among the basic questions in ecology. Knowledge about these processes is essential to predict changes in community composition in response to changes in for example climate or land use practices. LÄS MER
