    Nyckelord :Golden sand bee; Andrena marginata; Devil´s bit scabious; Succisa pratensis; Oligolectic bees; Inventory; Meadow land; Conservation;

    Sammanfattning : Over a decade ago, a conservation project aimed at preserving the endangered golden sand bee (Andrena marginata) populations in the Storån valley of the municipality of Marks was initiated. The species, red-listed in Sweden as well as in many other European country, specializes in pollen from Devil's bit. LÄS MER

  3. 2. Patterns and factors affecting brownification in a boreal river

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Emil Winqvist; [2021]
    Nyckelord :Bolmen; brownification; precipitation; discharge; sulfur deposition; land use; trend analysis; Technology and Engineering;

    Sammanfattning : During the last decades a brownification of the lakes and streams in the northern hemisphere has been observed. The change has been attributed to an increase of organic content in the water, leached from the top soil layers, called humic substances. LÄS MER

  4. 3. Application of HEC-HMS modelling on River Storån,Model evaluation and analysis of the processes by using soil moisture accounting loss method

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Pooja Makki Vijayaprakash; [2021]
    Nyckelord :River Storån; HEC-HMS; SMA; streamflow; baseflow; evapotranspiration; Technology and Engineering;

    Sammanfattning : River Storån, a major tributary of Lake Bolmen which is a source of fresh water to Skåne county of Sweden is found to alter the color of water in the lake due to the presence of natural organic matter. Hence it is of utmost importance to study the river to understand the dynamics of generation and flow of water from the river to the lake. LÄS MER

  5. 4. Modelling of water and material transport in River Storån to Lake Bolmen

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Imjal Sukupayo; [2021]
    Nyckelord :Brownification; Water Color; Dissolved Organic Matter; Discharge; hydraulic analysis; Tracer Analysis; Dispersion coefficient; Advection and Diffusion; Bolmen Lake; Storån River; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : The change of color of water from yellow to brown termed as brownification process is mainly due to leaching of humus and iron concentrations. In recent years, this problem is increasing in lake Bolmen, a major source of drinking water in Skåne county, Sweden. LÄS MER

  7. 5. Finns det bevis för täthetsberoende tillväxt eller överlevnad hos ettårig öring i Dammån och dess biflöden?

    Kandidat-uppsats, Karlstads universitet/Avdelningen för biologi

    Författare :Joachim Björkman; [2018]
