  1. 1. Inferring demographic history and speciation of grouse using whole genome sequences

    Författare :Radoslav Kozma; Jacob Höglund; Jeff A. Johnson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Demographic history; speciation; effective population size; adaptation; willow grouse; red grouse; black grouse; rock ptarmigan; Tetraoninae; conservation genetics; climate change; PSMC; species distribution modelling; FOXP4; Agouti;

    Sammanfattning : From an ecological perspective, knowledge of demographic history is highly valuable because population size fluctuations can be matched to known climatic events, thereby revealing great insight into a species’ reaction to past climate change. This in turn enables us to predict how they might respond to future climate scenarios. LÄS MER

  3. 2. Grouse - habitat relationships : monitoring, scale, and management

    Författare :Unni Støbet Lande; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Fennoscandian grouse populations are facing habitat degradation and are in decline, though not to the same degree as in western and central Europe. To be able to identify factors causing population decline and initiate proper management actions, a well functioning monitoring program and management are essential. LÄS MER

  5. 4. Biochemical genetic variation, intraspecific genetic structure and postglacial evolution of select north European vertebrate species

    Författare :Ulf Gyllensten; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution biologi ; Populationsgenetik;

    Sammanfattning : Analysis of the tempo and mode of intraspecific differentiation provides important information for understanding subspeciation, for construction of taxonomic hierarchies within a species and for management of genetic variation in natural populations.The present thesis describes the genetic structure of natural populations of willow grouse (Lagopus tagopus L.
