  2. 1. Interplay Between Environment and Genes on Morphological Variation in Perch – Implications for Resource Polymorphisms

    Author : Jens Olsson; Peter Eklöv; Mats Björklund; Richard Svanbäck; Andrew P. Hendry; Uppsala universitet; []
    Keywords : Ecology; Perch; Resource polymorphism; Genetic differentiation; Phenotypic plasticity; Morphology; Competition; Character divergence; Behavior; Growth rate; Resource level; Gut lenght; Ekologi;

    Abstract : Recent research has suggested that individual specialization within populations could be substantial and more common than previously acknowledged. Eurasian perch is one of many species of fish in lakes of postglacial origin that displays a morphological and dietary variation tightly coupled to the littoral and pelagic habitats of the lake.

  4. 2. Metapopulations dynamics and sex-specific resource allocation in Silene dioica

    Author : Elisabet Peedu; Pär Ingvarsson; Barbara Giles; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Silene dioica; Skeppvik Archipelago; Metapopulation Dynamics; Population Genetic Structuring; Genetic Diversity; Gene Flow; Sex-Specific Resource Allocation; Cost of Reproduction; Life-History Theory; Sexual Dimorphism; Reproductive Effort; biology; biologi; evolutionär genetik; evolutionary genetics; ekologisk botanik; Ecological Botany;

    Abstract : Rising archipelagos provide unique settings for the study of the temporal and spatial dynamics of their biota. This offers the possibility to study the ecology and genetics of early successional processes; both between islands that differ in age and within islands when already established organisms have to keep pace with the changing environment.

  5. 3. Life-history traits and population differentiation in a clonal plant: implications for establishment, persistence and weediness

    Author : Johanna Eneström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; weediness; Clonal plant; resource sharing; resource storage; partitioning of genetic variation; seedling development; seed recruitment; Aegopodium podagraria;

    Abstract : Clonality is wide-spread among plants, and clonal plants dominate many habitats and include many highly invasive species. Clonal growth incurs both advantages and costs and clonal plants often have reduced sexual reproduction compared to non-clonal plants which could be expected to lower genetic variation and hence evolutionary potential.

  6. 4. Genetic Studies in Dogs Implicate Novel Genes Involved in Atopic Dermatitis and IgA Deficiency

    Author : Katarina Tengvall; Kerstin Lindblad-Toh; Göran Andersson; Åke Hedhammar; Gerli Rosengren Pielberg; Ingrid Skelton Kockum; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GWAS; canine model; genetic association; immunogenetics; atopic dermatitis; IgA deficiency; Molekylär genetik; Molecular Genetics;

    Abstract : This thesis presents genetic studies of atopic dermatitis (AD) and IgA deficiency in dogs.AD is a chronic inflammatory and pruritic skin disorder caused by allergic reactions against environmental allergens. Both genetic and environmental factors are involved in the development of Canine AD (CAD) and human AD. READ MORE

  7. 5. Mapping genetic diseases in northern Sweden

    Author : Elisabet Einarsdottir; Dan Holmberg; Gösta Holmgren; Ulf Gyllensten; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; isolated populations; linkage disequilibrium; linkage analysis; genome-wide scan; hereditary sensory and autonomic neuropathy; type 1 diabetes mellitus; type 2 diabetes mellitus; autoimmune thyroid disease; Genetik; Clinical genetics; Klinisk genetik; medicinsk genetik; Medical Genetics;

    Abstract : The population of northern Sweden has previously been shown to be well suited for the mapping of monogenic diseases. In this thesis we have tested the hypothesis that this population could also be used for efficient identification of risk genes for common diseases. READ MORE
