  1. 16. Assessment of nutrient loading in lake Ringsjön from the catchment of Hörbyån Creek in Southern Sweden.

    University essay from KTH/Mark- och vattenteknik

    Author : Durgesh Kumar Singh; [2013]
    Keywords : Eutrophication; Nutrient loading; HEC-RAS and Water Quality;

    Abstract : Lake Ringsjön, located in south of Sweden, has been subject of eutrophication since 1950s and received several restoration efforts. Latest restoration effort, “Project Ringsjön”, was proposed in 2003 to improve lake condition against eutrophication by reducing nutrient concentration. READ MORE

  3. 17. Spatial and Temporal Variation in the Quality of Summer Foods for Herbivores along a Latitudinal Gradient

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Michaela Holá; [2012]
    Keywords : nutrient variability; Betula pubescens; Epilobium angustifolium ; near infrared reflectance spectroscopy; Sweden; Spatiotemporal scales;

    Abstract : The spatial and temporal variation in nutritional quality of plants consumed by herbivores is considered as one of the main factors governing their feeding patterns and influencing their productivity. Plant nutrients vary in space and time both within and among plant species, at fine scales, and across large geographical scales, creating a heterogeneous environment where herbivores have to cope with variation in food quality at different spatiotemporal scales.

    Abstract : Bränder utgör en viktig roll i jordens system. Det är kritiskt för oss att förstå bränder och dess drivkrafter, för att på så sätt kunna förutspå brändernas förändring på grund av klimatförändring. READ MORE

  5. 19. Large-scale nutrient pattern in the Gulf of Bothnia with the hydrodynamic of its loads

    University essay from Institutionen för tema

    Author : Lukman Salawu; [2006]
    Keywords : Spatial Variation; Probability Mapping and Primary Production.;

    Abstract : Eutrophication, which is the most important degradation in water bodies, has been traced to the imposed loading of nutrients. Of interest is the fact that the process is often accompanied with undesirable effects, one of which is primarily the increased algae production at the surface and accumulation of biomass at the bottom and the secondary responses, which include a.

  6. 20. Epiphytic algae on Norway spruce needles in Sweden : geographical distribution, time-trends and influence of site factors

    University essay from SLU/Dept. of Forest Soils

    Author : Laura Poggio; [2002]
    Keywords : picea abies; leaves; algae; geographical distribution; trends; site factors; forest inventories; statistical methods; Sweden;

    Abstract : The occurrence of epiphytic vegetation in temperate and boreal forest is a fairly recent phenomenon. Epiphytic algae have increased especially on Norway spruce (Picea abies L.Karst.) needles in the southern part of Scandinavia and in Central Europe. READ MORE
