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

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

    Abstract : 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).

  2. 2. Habitat compensation in nature-like fishways : Effects on benthos and fish

    Author : Stina Gustafsson; Olle Calles; Martin Österling; Jostein Skurdal; Paul Giller; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biocanal; biodiversity; brown trout; freshwater pearl mussel; functional feeding groups; habitat heterogeneity; large woody debris; macroinvertebrates; PIT-tag; salmonids; Biology; Biologi;

    Abstract : The construction of nature-like fishways has become an increasingly common measure to restore longitudinal connectivity in streams and rivers affected by hydroelectric development. These fishways also have the potential to function as habitat compensation measures when running waters have been degraded or lost. READ MORE

  3. 3. Occurrence patterns of dead wood and wood-dependent lichens in managed boreal forest landscapes

    Author : Måns Svensson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Dead wood is a key resource for biodiversity, on which thousands of forest organisms are dependent. Because of current forest management, there has been a large-scale change in dead wood amounts and qualities, and consequently, many wood-dependent species are threatened. READ MORE

  4. 4. Effects of landscape patterns on small mammal abundance

    Author : Frauke Ecke; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Landscape Ecology; Landskapsekologi;

    Abstract : Several studies indicate a long-term decline in the numbers of voles in northern Fennoscandia. Altered land use and forest management practices have been proposed as possible causes of the decline. READ MORE
