  1. 1. Forest – stream linkages : Brown trout (Salmo trutta) responses to woody debris, terrestrial invertebrates and light

    Författare :Pär Gustafsson; Eva Bergman; Larry Greenberg; Kurt Fausch; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brown trout; growth; foraging; woody debris; terrestrial invertebrates; light; riparian zone; forestry; stream; Freshwater ecology; Limnisk ekologi; Biology; Biologi;

    Sammanfattning : Forests surrounding streams affect aquatic communities in numerous ways, contributing to energy fluxes between terrestrial and lotic ecosystems. The five papers in this thesis focus on woody debris, terrestrial invertebrates and light, three factors influenced by riparian zone structure, potentially affecting streams and brown trout (Salmo trutta).

  3. 2. Forest-stream linkages : Experimental studies of foraging and growth of brown trout (Salmo trutta L)

    Författare :Pär Gustafsson; Eva Bergman; Larry Greenberg; John Armstrong; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brown trout; diet; growth; riparian zone; forest-stream linkages; terrestrial invertebrates; light; primary production; Biology; Biologi; Biology; Biologi;

    Sammanfattning : Riparian vegetation along streams and rivers affects the aquatic community in numerous ways and often operates as a link for energy flux between forest and streams. The studies presented in this licentiate thesis focus on light and terrestrial invertebrates, two factors influenced by riparian zone structure, which potentially affect stream ecosystems and thus also brown trout (Salmo trutta).

  4. 3. Modelling Bidding Behaviour in Electricity Auctions : Supply Function Equilibria with Uncertain Demand and Capacity Constraints

    Författare :Pär Holmberg; Nils Gottfries; Chuan-Zhong Li; Mats Bergman; David Newbery; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business and economics; supply function equilibrium; asymmetry; uniqueness; oligopoly; capacity constraint; uniform-price auction; pay-as-bid auction; discriminatory auction; wholesale electricity market; Ekonomi; Business and economics; Ekonomi;

    Sammanfattning : In most electricity markets, producers submit supply functions to a procurement uniform-price auction under uncertainty before demand has been realized. In the Supply Function Equilibrium (SFE), every producer commits to the supply function that maximises his expected profit given the bids of competitors. LÄS MER

  5. 4. Communicating, Negotiating and Stereotyping : The roles of context, situation and gender in small group decision-making

    Författare :Pär Löfstrand; Ingrid Zakrisson; Patrick Millet; Richard Ahlström; Ann Bergman; Mittuniversitetet; []

    Sammanfattning : Making decisions together in groups takes an important role in society. Everywhere and in many different contexts people meet to make more or less formal decisions. As stereotypes constitute simplified group based perceptions of other people, decision-making groups risk making biased judgments and commit discriminating decisions. LÄS MER
