  2. 21. Genomic dynamics over contemporary time frames in wild salmonid populations

    Author : Sara Kurland; Linda Laikre; Kathryn Elmer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conservation genomics; genetic monitoring; whole-genome sequencing; metapopulation; salmonid; brown trout; effective population size; Pool-seq; genetic connectivity; intraspecific diversity; sympatric populations; populationsgenetik; Population Genetics;

    Abstract : Genetic diversity is the foundation of all biological variation. An approach for sustainable use and protection of genetic diversity is continuous sampling over space and time, i.e. monitoring. READ MORE

  4. 22. The evolution of sex chromosomes and sex-linked sequences in birds

    Author : Homa Papoli Yazdi; Hans Professor; Bengt Hansson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sex chromosomes; female heterogamety; recombination suppression; genetic map; inversions; genetic diversity; pseudoautosomal region; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Identifying the processes involved in the evolution of suppressed recombination between sex chromosomes and understanding their consequences for the evolutionary dynamics of sex-linked loci have been major topics of research during the last century. In this thesis, I used the avian ZW system, where females are the heterogametic sex, to investigate the underlying processes in sex chromosome evolution in birds. READ MORE

  5. 23. Genomics of population decline

    Author : Tom van der Valk; Katerina Guschanski; Aylwyn Scally; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; genetic diversity; minimal-invasive samples; population decline; inbreeding; genetic purging; eastern gorillas; Dryas monkey; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : With human populations forecasted to grow in the next decades, many mammals face increasing anthropogenic threats. The consequential population declines are a precursor to extinctions, as small populations are not only more sensitive to stochastic events, but reduction in population size is generally also followed by a decrease in genetic diversity, which in turn reduces adaptive potential and fitness of the population.

  6. 24. Genetics and ecology of natural populations

    Author : Elisabeth Lundqvist; Ulf Lagercrantz; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Angelica archangelica; Bistorta vivipara; Viscaria alpina; Eiseniella tetraedra; ecotypes; hydrochory; genetic differentiation; clone diversity; genetic patterns; riparian;

    Abstract : I have studied the genetic variation of single species using morphological variation and enzyme electrophoresis. I have striven to understand the interaction between the breeding structure and the ecology of the species in relation to the community, in which it lives. The work was done in the county of Västerbotten, northern Sweden. READ MORE

  7. 25. Genetic analysis of murine malaria

    Author : Susana Campino; Dan Holmberg; Nils Lycke; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Malaria; genetic analysis; Plasmodium; wild derived inbred strains; loci; cerebral malaria; hyperparasitaemia.; Genetik; Clinical genetics; Klinisk genetik; genetik; Genetics;

    Abstract : Malaria, an infectious disease caused by Plasmodium parasites, is one of the major world-scale health problems. Despite the efforts aimed at finding an effective way to control the disease, the success has been thwarted by the emergence of parasite drug resistance and mosquito resistance to insecticides.
