    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zooplankton; spring; 0 fish; macrophytes; phenology; climate change; shallow lakes;

    Abstract : Shallow lakes such as Lake Krankesjön are characterized by their extended littoral zones, usually covered by submersed and emergent vegetation. In paper 1, I investigated the relationship between turbidity and macrophyte growth (Chara spp. READ MORE

    Abstract : Popular Abstract in Swedish Bekämpningsmedel och algblomningar - finns det någon koppling? Inom det konventionella jordbruket används idag regelmässigt stora mängder bekämpnings-medel, bara i sverige spreds under år 2001 mer än 1700 ton kemiska bekämpnings-medel på åkrarna. Ett stort problem med användandet av dessa ämnen är risken att de sprids och förorenar den intilliggande naturen. READ MORE

  4. 4. Interactions between Bacteria and Fungi on Aquatic Detritus – Causes and Consequences

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Cecilia Mille-Lindblom; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; bacteria; fungi; decomposition; antagonism; extracellular enzymes; competition; macrophytes; dissolved organic carbon DOC ; ergosterol; Ekologi; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi;

    Abstract : Bacteria and fungi dominate the decomposition of aquatic plants, a major process in the carbon and nutrient cycling in many aquatic systems. Although phylogenetically distant, bacteria and fungi often live in close proximity with each other. Since these microorganisms also have similar ecological functions, interactions have developed between them. READ MORE

    Abstract : Popular Abstract in Swedish Betydelsen av tryckinducerad syrgastransport hos övervattensväxter Min avhandling handlar om vikten av att syrgas transporteras till rötter och rhizom hos övervattensväxter som bladvass, kaveldun och säv. Syrgas behövs för cellandningen i alla växtdelar, och i synnerhet i rötterna då de växer fort och har hög ämnesomsättning. READ MORE
