  1. 11. Mosquitoes as a Part of Wetland Biodiversity

    Författare :Martina Schäfer; Jacob Höglund; Jan Lundström; Darold Batzer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; diversity patterns; species assemblages; functional groups; constructed wetlands; dytiscids; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    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

  2. 12. Macroalgae in the Baltic Sea : responses to low salinity and nutrient enrichment in Ceramium and Fucus

    Författare :Lena Bergström; Lars Ericson; Lena Kautsky; Erik Bonsdorff; Christine A Maggs; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; adaptation; asexual reproduction; Baltic Sea; Gulf of Bothnia; salinity; macroalgae; nutrients; sexual reproduction; stress; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    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.

  3. 13. Spatial Modelling of Coastal Fish – Methods and Applications

    Författare :Göran Sundblad; Ulf Bergström; Alfred Sandström; Peter Eklöv; Christian Möllmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; habitat; niche; species distribution modelling; juvenile; fish; larvae; spawning; Marine ecology; Marin ekologi; NATURAL SCIENCES; NATURVETENSKAP; Freshwater ecology; Limnisk ekologi; Biology; Biologi; Biology with specialization in Limnology; Biologi med inriktning mot limnologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Limnologi; Limnology;

    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

  4. 14. Shaping urban environments through human selection for plant traits

    Författare :Julie Goodness; Erik Andersson; Thomas Elmqvist; Pippin M. L. Anderson; Sarel Cilliers; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cape Town; cities; ecosystem services; environmental management; functional traits; interdisciplinary; landscaping preferences; residential landscapes; social-ecological system; Stockholm; traits; urban ecology; Kapstaden; städer; kulturella ekosystemtjänster; ekosystemtjänster; miljöförvaltning; funktionella egenskaper; tvärvetenskaplig; anläggningspreferenser; bostadsmiljö; socialekologiska system; Stockholm; växtegenskaper; urban ekologi; Sustainability Science; vetenskap om hållbar utveckling;

    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

  5. 15. Biodiversity and Ecosystem Functioning : What Diversity? Which Functioning?

    Författare :Fabian Roger; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Biodiversity; Ecosystem functioning; Multifunctionality; Microbial Ecosystems;

    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
