11. Mosquitoes as a Part of Wetland Biodiversity
Sammanfattning : Wetlands contain both aquatic and terrestrial environments which generates high biodiversity. However, they are commonly associated with mosquitoes (Diptera: Culicidae), and mosquitoes are usually regarded as negative by humans because they can cause nuisance and transmit diseases. LÄS MER
12. Macroalgae in the Baltic Sea : responses to low salinity and nutrient enrichment in Ceramium and Fucus
Sammanfattning : The brackish Baltic Sea is a marginal environment for both marine and freshwater species. The rate of ecological differentiation is presumably high due to strong selection pressure from a gradient of decreasing salinity that has been present in its current state for only about 3 000 years.

13. Spatial Modelling of Coastal Fish – Methods and Applications
Sammanfattning : Environmental factors influence species and habitats on multiple scales creating a mosaic of distribution patterns. Studying factors shaping these patterns are central to our understanding of population dynamics and ultimately ecosystem functioning. LÄS MER
14. Shaping urban environments through human selection for plant traits
Sammanfattning : Cities, as home to the majority of the world’s people, are significant sites for addressing challenges of achieving sustainability and securing human wellbeing. Urban environments are complex social-ecological systems, and meeting these challenges requires better understandings of the interactions of social and ecological elements. LÄS MER
15. Biodiversity and Ecosystem Functioning : What Diversity? Which Functioning?
Sammanfattning : We share our planet with an estimated 8.7 million eukaryotic species and an uncountable number of bacteria and archaea. But that amazing diversity is under threat from overexploitation, habitat destruction and climate change. This realization has lead ecologists to study the consequences of species loss. LÄS MER
