2. 1. Hybrid sterility and genetic incompatibilities in Ficedula flycatchers

   Author : Carolina Segami; Anna Qvarnström; Scott Edwards; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Speciation; genetic incompatibilities; hybrid sterility; hybrid inviability; single-cell RNA seq; GRC; Ficedula; flycatcher; intrinsic post-zygotic isolation; BDMI;

   Abstract : Although the theory behind the mechanisms generating intrinsic post-zygotic isolation is well established, very few concrete examples of genetic incompatibilities have been described, especially in vertebrates. Consequently, our understanding of the evolutionary forces shaping the appearance of genetic incompatibilities between natural populations and the overall role of genetic incompatibilities in the speciation process is limited.

4. 2. Exploring genetic diversity in natural and domestic populations through next generation sequencing

   Author : Nima Rafati; Leif Andersson; Carl-Johan Rubin; Alvaro Martinez Bario; Craig Primmer; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecological adaptation; seasonal reproduction; Atlantic herring; domestication; speciation; rabbit; skeletal atavism; Shetland ponies; NGS; SMRT sequencing; genome; transcriptome; assembly; structural variation; genetic diversity; HCE; TSHR; SHOX; CRLF2;

   Abstract : Studying genetic diversity in natural and domestic populations is of major importance in evolutionary biology. The recent advent of next generation sequencing (NGS) technologies has dramatically changed the scope of these studies, enabling researchers to study genetic diversity in a whole-genome context.

5. 3. Speciation genomics in Ficedula flycatchers

   Author : Madeline Chase; Carina Mugal; Chris Jiggins; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; recombination; linked selection; selective sweeps; sex chromosomes; structural variation; birds; genome assembly; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Abstract : Understanding what evolutionary processes have shaped patterns of genomic differentiation between species is a major aim of speciation genomics. However, disentangling the role of different processes that generate similar patterns remains a substantial challenge. READ MORE

6. 4. 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. 5. Genomic and transcriptomic investigation of reproductive incompatibility in Drosophila

   Author : Guilherme Costa Baião; Lisa Klasson; Alistair Darby; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wolbachia; Drosophila; Drosophila paulistorum; Differential Gene Expression; Reproductive Incompatibility; Reproductive Isolation; Comparative Genomics; Transcriptomics; RNA-Seq; Heteroplasmy; Mitochondria; Genomic conflict; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

   Abstract : Both nuclear and cytoplasmic elements can contribute to the emergence of reproductive incompatibilities that influence evolution and speciation. In the projects that compose this thesis, we use genomics and transcriptomics to study some of those elements in Drosophila. READ MORE
