  1. 11. Biogeochemical processes in forest riparian zones : conceptualizing function and heterogeneity in boreal catchments

    Författare :Jose Ledesma; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The area of interaction between terrestrial and aquatic environments, i.e. the riparian zone (RZ), has long been recognized as an important landscape feature from both scientific and management perspectives. Surface water quality is to a great extent regulated by substances exported from RZs. LÄS MER

  3. 12. Groundwater connections between the boreal landscape and its headwater streams: the role of discrete riparian inflow points (DRIPs)

    Författare :Stefan W Ploum; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : River networks connect the Swedish boreal landscape with the Baltic Sea. Groundwater provides a majority of the river water, and therefore it is important to understand the mechanisms of groundwater-stream interactions. The riparian zone, or near stream area, is an important terrestrial interface where groundwater becomes stream water. LÄS MER

  4. 13. Fine stream wood : effects on drift and brown trout (Salmo trutta) growth and behaviour

    Författare :Åsa Enefalk; Eva Bergman; Anders Nilsson; Stanley Gregory; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stream fish; wood; salmonid; trout; aquatic invertebrates; behaviour; sheltering; Biology; Biologi;

    Sammanfattning : Stream ecosystems and their riparian zones have previously been regarded as two different ecosystems, linked through numerous reciprocal subsidies. Today, ecologists agree that the stream and the riparian zone should be regarded as one system, the stream-riparian ecosystem, which is characterised largely by the subsidies between land and water.

  5. 14. The potential of an unmanned aircraft system for surveying lake and river vegetation

    Författare :Eva Husson; Seppo Hellsten; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Landscape Ecology; Landskapsekologi;

    Sammanfattning : Vegetation in and along aquatic systems has important regulatory and ecological functions. Aquatic vegetation is also frequently used as an indicator of environmental conditions. To enhance our knowledge of the complex natural processes in the littoral zone, i.e. LÄS MER

  7. 15. Conceptualizing catchment processes affecting stream chemistry : from basic understanding to practical applications

    Författare :Tejshree Tiwari; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Maintaining good surface water quality is recognized as one of the greatest challenges for future generations. In northern-latitudes, it is predicted that aquatic ecosystems may experience a large climatic change. LÄS MER
