  1. 1. Changing attitudes to Swedish wolf policy : wolf return, rural areas, and political alienation

    Författare :Max Eriksson; Camilla Sandström; Göran Ericsson; Katarina Roos; Simon Matti; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; attitude change; political alienation; urban-rural conflict; governance; wolf policy; statskunskap; political science;

    Sammanfattning : In 1966, the grey wolf was listed as a protected species in Sweden. Since then, the Swedish wolf population has increased in size, making human-wolf encounters more common, particularly in rural areas. Previous qualitative research has shown that segments of the rural population perceive the wolf to be incompatible with traditional rural life. LÄS MER

  2. 2. Evolutionary genomics in Corvids : – From single nucleotides to structural variants

    Författare :Matthias H. Weissensteiner; Jochen B.W. Wolf; Manfred Grabherr; Kateryna M. Makova; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; evolutionary genetics; genomics; population genetics; selection; recombination; chromosomal features; colouration; insertion; deletion; inversion; crow; tandem repeat; transposable element; gene expression;

    Sammanfattning : Heritable genetic variation is the raw material of evolution and can occur in many different forms, from altering single nucleotides to rearranging stretches of millions at once. DNA mutations that result in phenotypic differences are the basis upon which natural selection can act, leading to a shift of the frequency of those mutations. LÄS MER

  3. 3. The Genetics of Speciation and Colouration in Carrion and Hooded Crows

    Författare :Jelmer Poelstra; Jochen Wolf; Hans Ellegren; Chris Jiggins; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; evolutionary genetics; genomics; birds; next-generation sequencing; pigmentation; pigmentation genetics; eumelanin; social selection; gene expression; population genomics; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : A fundamental goal in biological research is to gain an understanding of the evolutionary processes and genetic elements that drive speciation. Genes responsible for reproductive isolation in young divergent lineages are particularly poorly known. In this thesis, the speciation genetics of carrion (Corvus (corone) corone) and hooded (C. LÄS MER

  4. 4. Anthropogenic impact on predator guilds and ecosystem processes : Apex predator extinctions, land use and climate change

    Författare :Marianne Pasanen Mortensen; Bodil Elmhagen; Francisco Palomares; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mesopredators; apex predators; top-down; bottom-up; interspecific killing; red fox; Eurasian lynx; grey wolf; wolverine; productivity; winter severity; cropland; zoologisk ekologi; Animal Ecology;

    Sammanfattning : Humans affect ecosystems by changing species compositions, landscape and climate. This thesis aims to increase our understanding of anthropogenic effects on mesopredator abundance due to changes in apex predator status, landscape and climate. LÄS MER

  5. 5. From wolf to dog: Behavioural evolution during domestication

    Författare :Christina Hansen Wheat; Hans Temrin; Clive Wynne; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Domestication syndrome; behavioural evolution; behaviorual ontogeny; correlated traits; sociability; playfulness; aggression; fear; Canis familiaris; Canis lupus; artificial selection; etologi; Ethology;

    Sammanfattning : Biologists since Darwin have recognized that domestication, where species are selected to live in human-controlled environments, exerts strong selection on organisms and dramatically impacts their evolutionary trajectories. Across domesticated mammal species, characteristic morphological, physiological and behavioural changes occur simultaneously, as correlated traits, a phenomenon known as the domestication syndrome.
