2. 1. 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

4. 2. Extracting Genomic Variations using Selector Technology

   Author : Magnus Isaksson; Mats Nilsson; Radoje Drmanac; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Selector; Selector probe; Genetic variation; Resequencing; Targeted sequencing; copy-number variations; MLGA; Bioinformatics; Next generation sequencing; NGS; Amplified single molecule; ASM; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Genetics; Genetik; Molekylär medicin; Molecular Medicine;

   Abstract : This thesis describes the development and use of a new class of molecular tools called Selector probes, and its potential for investigations of genetic variation. The Selector technology provides multiplex amplification of targeted DNA sequences with a high specificity, and an enrichment factor in the same order of magnitude as PCR. READ MORE

5. 3. Morphometric and molecular variation in the Nordic dogroses (Rosa Sect. Caninae, Rosaceae)

   Author : Åsa Olsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systematisk botanik; chemotaxonomy. Physiology of nonvascular plants; Genetic diversity; Geographic differentiation; Systematic botany; RAPDs; taxonomy; morphology; phytogeography; kemotaxonomi. Växters fysiologi inte kärlväxter .; taxonomi; morfologi;

   Abstract : In the present thesis, I investigate the hierarchical structure of morphometric and molecular diversity within and between the Nordic dogroses (Rosa Sect. Caninae, Rosaceae). I also investigate patterns of geographic differentiation and taxonomic relationships within the group. READ MORE

6. 4. 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.

7. 5. Diversity of landraces and wild forms of watermelon (Citrullus lanatus) : distribution and implications for conservation in southern Africa, with emphasis on Zimbabwe

   Author : Claid Mujaju; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Watermelon (Citrullus lanatus) is commonly grown in traditional agrosystems throughout the drought-prone Southern Africa as a staple food (edible seeds), a dessert food (edible flesh), and for animal feed. Several morphotypes of watermelon are found in this area; sweet watermelon, cooking melon and seed melon landraces of the traditional agrosystems; and possibly introgressed types which are regarded as agronomic weeds.
