  1. 16. Below, above and beyond – seagrass ecosystem functions in a connected coastal landscape

    Författare :Theodor Kindeberg; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coastal adaptation; beach wrack; eelgrass; carbon cycling; infauna; seagrass restoration; nature-based solution; biodiversity; eddy covariance; functional traits; Zostera marina;

    Sammanfattning : Seagrass meadows constitute important habitat for a plethora of organisms, rendering them important habitats for conserving biodiversity. Seagrass meadows also modify the environment by attenuating wave and current energy. LÄS MER

  3. 17. Grow with the flow : Hydrological controls of riparian vegetation in boreal stream networks

    Författare :Lenka Kuglerová; Roland Jansson; Hjalmar Laudon; Birgitta Malm-Renöfält; John Stella; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boreal forest; channelization; groundwater; Krycklan catchment; liverworts; mosses; riparian buffers; riparian vegetation; river restoration; species richness; stream network; stream size; vascular plants;

    Sammanfattning : What drives species diversity across landscapes is one of the most fundamental questions in ecology. Further, understanding the mechanisms underlying species diversity patterns is important not only for forming and challenging ecological theories but also essential for appropriate landscape management and effective nature conservation.

  4. 18. Ecology of freshwater mussels in disturbed environments

    Författare :Martin Österling; Larry Greenberg; Björn Arvidsson; David Strayer; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Unionoida; Margaritifera margaritifera; Dreissena; Salmo trutta; habitat degradation; turbidity; sedimentation; recruitment; conservation.; Biology; Biologi; Biology; Biologi;

    Sammanfattning : The number of species extinctions is increasing at an alarming rate. Long-lived freshwater mussels of the order Unionoida, which include a parasitic stage on a host fish, are highly threatened. Habitat degradation by turbidity and sedimentation is thought to be one major reason for their decline. LÄS MER

  5. 19. Local baseline knowledge for conservation and restoration of degraded ecosystems in Ecuador

    Författare :Ana Mariscal; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Deforestation and land-use changes are a major threats to native ecosystem in many tropical countries, including Ecuador– one of the biodiversity hotspots in the world. In tropical Andean countries, natural ecosystems change over small spatial scales. LÄS MER

  7. 20. Habitat requirements and preservation of the beetle assemblages associated with hollow oaks

    Författare :Nicklas Jansson; Per Milberg; Karl-Olof Bergman; Simon Grove; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : One of the most endangered assemblages of species in Europe is saproxylic beetles associated with old trees. To be able to conserve these species there is a need of developing methods to survey the fauna and to evaluate the conservation value of different oak habitats, develop instruments for landscape planning and detailed knowledge of species habitat requirements.
