1. Biodiversity patterns and the processes regulating them along elevation gradients in the Swedish mountains
Sammanfattning : Biodiversity describes the total variation of life and includes the taxonomic, genetic, and phenotypic differences among organisms. Variations of biodiversity in space and time may be driven by ecological, evolutionary, or neutral processes. LÄS MER
2. Eco-evolutionary processes and community patterns--- novel avenues for studying biodiversity across spatial and temporal scales
Sammanfattning : Understanding biodiversity patterns poses a persistent challenge due to the complex interconnections of ecological and evolutionary processes. The particular difficulty comes from the various processes influencing biodiversity patterns across different spatial scales. LÄS MER
3. Grassland restoration : Connectivity, plant community change and cows
Sammanfattning : The ecological significance of semi-natural grasslands is high because these habitats provide a home for a diverse flora and fauna and support a range of associated ecosystem services. Due to large-scale land-use changes the extent of grassland habitat has declined. LÄS MER
4. Bacterioplankton population dynamics in a changing ocean
Sammanfattning : Bacterioplankton is characterized by high diversity, short generation times and rapid turnover. Despite their small size, these numerous microorganisms are a fundamental piece of aquatic ecosystems by channeling carbon to higher trophic levels through dissolved organic matter utilization.

5. Plant community assembly during succession from arable fields to semi-natural grassland
Sammanfattning : Large areas of grazed, species rich semi-natural grassland were lost in Europe during the last two centuries and as a consequence led to decreases in grassland specialist species. Therefore, today the “restoration” of grassland on previously arable fields is recommended for the protection of grassland specialists. LÄS MER
