  4. 2. Genetic structure in the North- population connectivity and social organization in the Arctic fox

    Author : Karin Norén; Anders Angerbjörn; Páll Hersteinsson; Benjamin Sacks; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; zoologisk ekologi; Animal Ecology;

    Abstract : Genetic variation is distributed on different spatial and temporal scales, reflecting the ecological and geographical complexity in the habitat. In this thesis, the primary objective was to obtain a comprehensive understanding of the genetic structuring in the Arctic fox (Vulpes lagopus) and to identify the underlying factors forming these structures.

  5. 3. Dynamics of inbreeding and genetic rescue in a small population

    Author : Malin Hasselgren; Karin Norén; Carles Vilà; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; inbreeding; inbreeding depression; genetic rescue; fitness; genomics; conservation genetics; mutational load; arctic fox; pedigree; gene flow; zoologisk ekologi; Animal Ecology;

    Abstract : Isolation at small population size can reduce individual fitness and impede population growth caused by inbreeding and genetic drift (i.e. inbreeding depression). Inbreeding depression can however be circumvented by gene flow from unrelated individuals through masking of recessive deleterious alleles and contribute to population persistence (i. READ MORE

  6. 4. The use of museum specimens in conservation genomics

    Author : Johanna von Seth; Love Dalén; Karin Norén; Gernot Segelbacher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conservation genomics; museum specimens; genomic erosion; diversity; inbreeding; mutational load; genetic drift; purging; population divergence; local extinction; population decline; Sumatran rhinoceros; kakapo; arctic fox; Chatham Island black robin; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : In the face of an increasing number of species being threatened by extinction, museum collections can constitute a powerful resource for acquiring genomic data of endangered taxa. By utilising datasets that combine genomes from present-day populations with those from historical timepoints, several questions relevant for conservation can be investigated. READ MORE
