  2. 6. Hidden biodiversity in an alpine freshwater top predator : Existence, characteristics, and temporal dynamics of cryptic, sympatric brown trout populations

    Author : Anastasia Andersson; Linda Laikre; Nils Ryman; Paulo Prodöhl; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cryptic sympatry; population genetic structure; sympatric populations; intraspecific biodiversity; genetic monitoring; conservation genetics; trophic polymorphism; genetic connectivity; temporal stability; Salmo trutta; populationsgenetik; Population Genetics;

    Abstract : Intraspecific genetic diversity is imperative to the survival of species in a changing environment, and it plays a vital role in ecosystem function. Since this type of diversity can be difficult to detect it is sometimes referred to as “hidden biodiversity”. READ MORE

  4. 7. Ethnic heterogeneity of the North-Swedish population : its origin and medical consequences

    Author : Per-Olof Nylander; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ethnic heterogeneity; Northern Sweden; Population genetics; Finns; Saamis; Genetic markers; Hypercholesterolemia;

    Abstract : Northern Sweden shows a unique population structure with remarkable geographical variations in the distribution of genetic disorders as well as genetic markers like blood groups, serum groups and red cell enzyme types. The present-day population of northern Sweden is a mixture of people of Finnish, Saamish (Lappish) and Central-Swedish origin. READ MORE

  5. 8. Effects of Agriculture on Abundance, Genetic Diversity and Fitness in the Common Frog, Rana temporaria

    Author : Markus Johansson; Anssi Laurila; Juha Merilä; Craig R. Primmer; Michael W. Bruford; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; agriculture; agrochemicals; amphibians; effective population size; genetic diversity; genetic structure; hierarchical sampling; microsatellites; Rana temporaria; Biologi; Biology; Biologi;

    Abstract : The aims of this thesis were to evaluate the effects of agriculture on amphibians in terms of (i) population genetic consequences of agriculture-induced spatial changes of the landscape and (ii) local adaptation and tolerance to frequently used agrochemicals. The study was performed using the common frog Rana temporaria as a model. READ MORE

  6. 9. Assessing and monitoring genetic patterns for conservation purposes with special emphasis on Scandinavia

    Author : Anna Palmé; Nils Ryman; Linda Laikre; Kerry Naish; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biological diversity; conservation genetics; management unit; spatial genetic structure; sympatric populations; genetic monitoring; release of alien populations; northern pike; brown trout; harbour porpoise; Biology; Biologi; populationsgenetik; Population Genetics;

    Abstract : Genetic variation is essential for biological evolution, for maintaining viability of populations, and to ensure ecosystem resilience. Increased human exploitation and environmental change result in rapid loss of biological variation, including genetic diversity. READ MORE

  7. 10. Population Genetic Structure of Black Grouse (Tetrao tetrix) : From a Large to a Fine Scale Perspective

    Author : Carolina Corrales Duque; Jacob Höglund; Staffan Bensch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; black grouse; control region; demographic expansion; kin selection; lek; microsatellites; non-invasive sampling; postglacial colonisation; philopatry; phylogeography; sex-biased dispersal; spatial genetics; subspecies; suture zone; refugia; Biology; Biologi; Systematics and phylogenetics; Systematik och fylogeni; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Abstract : Black grouse (Tetrao tetrix) is a bird species with a lek mating system found in the Palearctic boreal taiga. It is assumed that it has a continuous distribution along Scandinavia and Siberia, whereas in Central Europe it has declined during the last decades. READ MORE
