  2. 11. 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. 12. On Ingeae Systematics of synandrous mimosoids

    Author : Julia Ferm; Bertil Ståhl; Tiina Särkinen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fabaceae; Ingeae; Systematics; Phylogenetics; Taxonomy; Morphology; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : Background: The Ingeae tribe (Caesalpiniodeae, Fabaceae) has a long history of taxonomic complexity with genera being merged and split, and many species with former placements in several different genera. Moreover, phylogenetic studies have shown that the tribe is non-monophyletic with the genus Acacia (of tribe Acacieae) nested within Ingeae. READ MORE

  5. 13. Full circle : Rise and fate of genetic variation in Marasmius oreades fairy rings

    Author : Markus Hiltunen; Hanna Johannesson; Martin Ryberg; Jason Stajich; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mushroom; fairy ring; Marasmius; mutation; fungi; genomics; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : Genetic variation is a prerequisite for evolution. The degree of variability within a species is governed by forces including mutation, recombination and selection. READ MORE

  6. 14. The exploration and evolution of the avian genomic dark matter

    Author : Valentina Peona; Alexander Suh; Hanna Johannesson; Rachel O'Neill; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolutionary genomics; genome assembly; sex chromosomes; birds; satellite DNA; transposable elements; endogenous retroviruses; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : The development and improvement of genome sequencing technologies in the last decade revolutionised the entire field of biology with genome assemblies of virtually any organism. Despite this tremendous progress, complex genomic regions are systematically missing from genome assemblies and form the so-called "genomic dark matter". READ MORE

  7. 15. Resolving deep nodes of eukaryote phylogeny

    Author : Caesar Al Jewari; Sandra L Baldauf; Fabien Burki; Antonis Rokas; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Eukaryote Tree of Life; Excavata; phylogenetics; phylogenomics; Mitochondria; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : My thesis aims to solve deep nodes in the eukaryote tree of life (eToL), by developing new data sets and new approaches to analysing them. In paper I, I described a dataset of 76 universal eukaryotic proteins of bacterial descent (euBacs), in order to test the relations among the three main divisions of mitochondriate eukaryotes (Amorphea, Diaphretickes and Discoba).
