  2. 16. Fungal molecular ecology in boreal forests and challenges associated with unidentified environmental DNA sequences

    Author : Kerri Kluting; Anna Rosling; Martin Ryberg; Sara Branco; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; amplicon sequence variant ASV ; Archaeorhizomycetes; environmental DNA sequencing; high-throughput sequencing; integrative taxonomy; pine forest; podzol soil profile; Pucciniomycotina; Tomicus piniperda; voucherless specimens; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Many fungi are characteristically difficult to observe and collect, making the process of documenting the world’s fungal diversity challenging. The vast majority of fungal species are undescribed. READ MORE

  4. 17. Meiotic Recombination in Human and Dog : Targets, Consequences and Implications for Genome Evolution

    Author : Jonas Berglund; Matthew Webster; Kerstin Lindblad-Toh; Leif Andersson; Nadia Singh; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; recombination; biased gene conversion; CpG island; copy number variation; substitutions; methylation; Bioinformatics; Bioinformatik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Molekylär genetik; Molecular Genetics;

    Abstract : Understanding the mechanism of recombination has important implications for genome evolution and genomic variability. The work presented in this thesis studies the properties of recombination by investigating the effects it has on genome evolution in humans and dogs. READ MORE

  5. 18. The Evolution of Sex Chromosomes and Dosage Compensation in Structurally Dynamic Butterfly Genomes

    Author : Lars Höök; Niclas Backström; Elina Immonen; Beatriz Vicoso; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sex chromosome evolution; Dosage compensation; Sex-biased gene expression; Faster-Z; Lepidoptera; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Dimorphic sex chromosomes have evolved independently throughout evolution from initially homologous autosomes. Recombination suppression between the sex chromosomes causes one sex chromosome to degenerate, which will influence evolution of sex-linked genes. READ MORE

  6. 19. Strategy framework for sustainable industrial development in sub-Saharan Africa: Systems-evolutionary approach

    Author : Desta Mebratu; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sustainable development; Sustainability; systems dynamics; evolutionary; development strategy; Economics of development; Environmental technology; Utvecklingsekonomi; kontroll av utsläpp; Miljöteknik; pollution control;

    Abstract : The principal objectives of this research were: · to develop a conceptual framework on sustainability and sustainable development and · to propose a strategy framework for sustainable industrial development in Sub-Saharan Africa (SSA). The research was done based on systems evolutionary approach having the following methodological principles as a guide. READ MORE

  7. 20. Multi-trait Branching Models with Applications to Species Evolution

    Author : Daniah Tahir; Ingemar Kaj; Martin Lascoux; Asger Hobolth; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Markov models; branching processes; density dependence; discrete traits; species trees; diversification rates; diffusion approximation;

    Abstract : This thesis provides an analysis of the evolution of discrete traits and their effect on the birth and survival of species using the theory of supercritical, continuous time Markov branching processes. We present a branching modeling framework that incorporates multi-trait diversification processes associated with the emergence of new species, death of existing species, and transition of species carrying one type of a trait to another.
