  1. 21. 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.

  3. 22. Substrate control of community composition and functional adaptation in marine bacterioplankton

    Författare :Julie Dinasquet; Lasse Riemann; Edward F. DeLong; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marine microbial ecology; bacterioplankton; community composition; functional adaptation; dissolved organic carbon; bottom-up and top down factors; ctenophore Mnemiopsis leidyi; food-webs; Southern-Ocean; Antarctica; Mikrobiologi; Microbiology; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : A drop of sea-water is teeming with a million of bacteria, on which pelagic food-webs and biogeochemical cycles depend. These bacteria thrive on a wide range of dissolved organic carbon (DOC) compounds produced through biotic and abiotic processes. LÄS MER

  4. 23. Effects of morphometric isolation and vegetation on the macroinvertebrate community in shallow Baltic Sea land-uplift bays

    Författare :Joakim Hansen; Lena Kautsky; Erik Bonsdorff; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lagoons; macrofauna; macrophytes; hydrophytes; charophytes; ecological succession; structural complexity; habitat complexity; habitat selection; species composition; biodiversity; stable isotopes; food web; Terrestrial; freshwater and marine ecology; Terrestrisk; limnisk och marin ekologi; Plant Ecology; växtekologi;

    Sammanfattning : Shallow sheltered Baltic Sea bays are ecologically important habitats that harbour a unique vegetation community and constitute vital reproduction areas for many coastal fish species. Knowledge about the invertebrate community in these bays is, however, limited. LÄS MER

  5. 24. Response of marine food webs to climate-induced changes in temperature and inflow of allochthonous organic matter

    Författare :Rickard Degerman; Agneta Andersson; Risto Lignell; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate change; bacterial production; mesocosm; food web efficiency; Baltic Sea;

    Sammanfattning : Global records of temperature show a warming trend both in the atmosphere and in the oceans. Current climate change scenarios indicate that global temperature will continue to increase in the future. The effects will however be very different in different geographic regions. LÄS MER

  7. 25. Thiamine dynamics in the pelagic food web of the Baltic Sea

    Författare :Peter Sylvander; Snoeijs Pauline; Anders Bignert; Dale C Honeyfield; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thiamine; Vitamin B1; Baltic Sea; M74; marin ekologi; Marine Ecology;

    Sammanfattning : Thiamine (vitamin B1) is involved in several basal metabolic processes. It is an essential compound for many organisms and in aquatic systems it is mainly produced by phytoplankton and prokaryotes and transferred to higher trophic levels through grazing and predation. LÄS MER
