  1. 1. Ecology and Genomics of a male-killing Wolbachia

    Author : Anne Duplouy; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wolbachia; male-killing; Lepidoptera;

    Abstract : In my PhD thesis I have studied different aspects of the biology of the male-killing (MK) Wolbachia strain wBol1 that infects the tropical butterfly Hypolimnas bolina. First I have investigated the causes and consequences of the recent spread of wBol1 in the South Pacific Islands, bringing new insights into the biogeography of this bacterium. READ MORE

  2. 2. Genomic and transcriptomic investigation of reproductive incompatibility in Drosophila

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Guilherme Costa Baião; Lisa Klasson; Alistair Darby; [2020]
    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

  3. 3. Genome Evolution and Niche Differentiation of Bacterial Endosymbionts

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kirsten Maren Ellegaard; Siv Andersson; Andrés Moya; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; niche; habitat; endosymbiont; gut microbiome; honey bee; Wolbachia; comparative; genomics;

    Abstract : Most animals contain chronic microbial infections that inflict no harm on their hosts. Recently, the gut microflora of humans and other animals have been characterized. However, little is known about the forces that shape the diversity of these bacterial communities. READ MORE

  4. 4. Genome Evolution in Maternally Inherited Insect Endosymbionts

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lisa Klasson; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : Symbiosis is a widely common phenomenon in nature and has undoubtedly contributed to the evolution of all organisms on earth. Symbiotic associations can be of varying character, such as parasitic or mutualistic, but all imply a close relationship. READ MORE
