  2. 1. Biomass patterns in boreal-subarctic lake food webs along gradients of light and nutrients

    Author : Gustaf Thomsson; Sebastian Diehl; Dag Olav Hessen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; boreal-subartic lake; cDOM; epilithon; benthic-pelagic coupling; carnivores;

    Abstract : There is large natural variation in light and nutrient conditions across lakes. In the boreal-subarctic region most lakes are small, shallow and nutrient poor. In such lakes there is often sufficient light to support primary production at the lake bottom. READ MORE

  4. 2. Conservation Genetics of Scandinavian Wolverines

    Author : Eva Hedmark; Hans Ellegren; Lisette Waits; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; carnivores; conservation; genetic monitoring; molecular sexing; non-invasive genetic techniques; parentage analysis; tanning; Genetik; Gulo gulo; Genetics; Genetik;

    Abstract : In this thesis, genetic methods for individual identification and sex determination of wolverines from non-invasive samples were developed and applied in genetic monitoring of Scandinavian wolverine populations. Paternity and mating system of wolverines were studied by combining genetic analysis with telemetry data. READ MORE

  5. 3. Indirect effects of predation in human-modified landscapes

    Author : Ellinor Sahlén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Large carnivores affect prey species, with cascading effects on entire ecosystems. In anthropogenic regions large carnivores come into conflicts with humans, especially in rural areas where farming and hunting traditions are widespread. As a result, large carnivores have been eradicated from many regions across their historical distribution. READ MORE

  6. 4. Economic Studies on Wildlife Management and Conservation

    Author : Julian Eduardo Lozano Galindez; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : The present research consists of four articles addressing wildlife management and conservation using different methodological approaches of applied economics. The thesis encompasses various economic analyses on three carnivore species mainly: the wolf (Canis lupus), the brown bear (Ursus arctos), and the lynx (Lynx lynx). READ MORE

  7. 5. Managing green infrastructures : trophic interactions in anthropogenic and natural ecosystems

    Author : Michael Manton; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The term green infrastructure addresses the spatial structure of anthropogenic, semi-natural and natural areas, as well as other environmental features which enable society to benefit from ecosystems’ multiple services. Focusing on two green infrastructures, anthropogenic wet meadows and natural forest successions, this thesis applies a macro-ecological approach based on comparisons of multiple landscapes as complex social-ecological systems.
