1. Island biogeography of young land uplift islands - viewed through the lens of bryophytes in a northern Swedish archipelago
Abstract : Increasing habitat fragmentation and rapid global warming is changing the conditions for species populations and ecological communities around the world. This presents challenges for the maintenance of biodiversity and a dominant paradigm for conservation in fragmented habitats is given by island biogeography and metapopulation (or metacommunity) ecology.

2. Factors influencing the biogeography of bacteria in fresh waters - a metacommunity approach
Abstract : One of ecology’s primary goals is to comprehend biodiversity and its patterns of distribution over space and time. Since microorganisms play a pivotal role in key ecological processes, the diversity of microbial communities may have important implications for the stability and functioning of Earth’s ecosystems.

3. Assembly of Gut Microbial Communities in Freshwater Fish and Their Roles in Fish Condition
Abstract : Animal hosts provide associated microorganisms with suitable ecological niches in their intestines. Microbes help their hosts to digest food, protect against pathogens, and influence the host’s metabolisms. Compositional variation of gut microbial communities is common among hosts, and may affect the health status of hosts. READ MORE

4. Ecology of parasitoids and their hosts in oilseed rape fields
Abstract : Oilseed rape fields are a very common crop in the agricultural landscape of southern Sweden, and they can harbour surprisingly many insect species. Some of them are herbivores that feed on various parts of the oilseed rape plant, others are natural enemies of the herbivores, and even more species are tourists from the surrounding landscape.

5. Function follows Form : Trait-based approaches to climate change effects on wetland vegetation and functioning
Abstract : Climate change and habitat fragmentation are altering the structure and functioning of plant communities world-wide. Understanding how, why and with what consequences are major challenges of ecology today. Trait-based approaches focus on functional rather than taxonomic identity to facilitate process-based explanation and prediction. READ MORE
