  1. 1. Metals take flight : Transport and effects across ecosystems

    Författare :Johan Lidman; A. M. M. Berglund; Micael Jonsson; Christian Bigler; Brendan Mckie; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metals; aquatic subsidies; passerines; aquatic insects; environmental science; miljövetenskap; ekotoxikologi; Ecotoxicology;

    Sammanfattning : Metal contamination can have severe toxic effects in the ecosystems, resulting in loss of biodiversity, reduced abundance of organisms, and loss of ecosystem services. Traditionally, aquatic ecosystems have been regarded as a sink of metal contamination. LÄS MER

  3. 2. The Spider and the Sea : Effects of marine subsidies on the role of spiders in terrestrial food webs

    Författare :Kajsa Mellbrand; Peter Hambäck; Lena Kautsky; David Wise; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marine subsidies; food webs; stable isotopes; shore ecosystems; predators; spiders; Pardosa; algae; emerging insects; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Plant Ecology; växtekologi;

    Sammanfattning : The purpose of this study was to identify if terrestrial arthropod predators on Baltic Sea shores vary in their use of marine versus terrestrial food items, and to construct a bottom-up food web for Baltic Sea shores. The inflow of marine nutrients in the area consists mainly of marine algal detritus and emerging aquatic insects (e.g. LÄS MER

  4. 3. 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. 4. Forests, Functions, and Food Webs : Riparian processes through an ecological and molecular lens

    Författare :Jeffery Marker; Eva Bergman; Rolf Lutz Eckstein; Denis Lafage; Rachel E. Bowes; Ann Erlandsson; John S. Richardson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Riparian systems; functional diversity; stable isotope analysis; metabarcoding; Tetragnathidae; Lycosidae; forestry management; prey subsidies; Biology; Biologi;

    Sammanfattning : Riparian systems are critical ecological interfaces that have a significant impact on the surrounding aquatic and terrestrial ecosystems. The riparian and surrounding systems have significant roles in regulating energy flow, providing essential nutrients, and supporting unique species, making them important for ecosystem function.

  7. 5. Land use effects on ecological linkages between small streams and their surrounding terrestrial habitats

    Författare :Peter Carlson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Adult aquatic insects are important vectors for aquatic transfers to terrestrial consumers and an integral component of riparian and terrestrial food webs. Incorporation of aquatic subsidies into terrestrial food webs depends heavily on the dispersal and life history traits of aquatic insects. LÄS MER
