Chromosomal inversions as a mechanism for sympatric differentiation in common quails
Chromosomal inversions are key drivers of phenotypic divergence, local adaptation and early reproductive isolation, but their effects in highly mobile species remain poorly understood. In the common quail Coturnix coturnix, a large inversion on chromosome 1 spans about 12% of the genome and defines …

Chromosomal inversions and common quail diversification in Macaronesian archipelagos and the mainland
… biodiversity. In this thesis we investigate how chromosomal rearrangements and geographical fragmentation (islands) contribute to the diversification of a bird lineage. Specifically, we focus on the role of chromosomal inversions in maintaining polymorphisms within the highly mobile common quail …

Chromosomal Evolution of Malaria Vectors
… are highly plastic as evidenced by the wealth or chromosomal inversions that have occurred in this genus. Chromosomal inversions have been correlated with differences in adaptation to aridity, insecticide resistance, and differences in resting behavior. However, a good understanding of the …

Repetitive Sequences Drive Rapid Adaptation in Candida albicans
… bp) that are associated with CNVs, LOH, and chromosomal inversions during the acute stages of adaptation to azole antifungal drugs. Additionally, we describe the occurrence of complex CNVs that are associated with a decreased sensitivity to multiple azole antifungal drugs. We describe how …

Comparative genomics of chromosomal rearrangements in malaria mosquitoes
To better understand the evolutionary dynamics of chromosomal inversions, a physical map for an Asian malaria vector, Anopheles stephensi, was created and compared with the maps of the major African malaria vectors A. gambiae and A. funestus No interchromosomal transposition was observed between A. …

How Linkage Disequilibrium and Recombination Shape Genetic Variation Within and Between Species
… are difficult to disentangle. Between species, chromosomal inversions have been proposed to suppress recombination in hybrid inversion heterozygotes and thereby maintain LD and species distinction, but many models of how this happens are overly simplistic—they often ignore non-crossover gene …

Defining genomic drivers of evolution in the entomopathogenic Serratia spp. A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… Serratia. Through assessment of 52 whole chromosomal sequences, it was found that while S. entomophila pADAP bearing isolates shared a relatively conserved chromosome, that of S. proteamaculans were heterogeneous. The consistent and predictable disease phenotype caused by S. entomophila …

Chromosome and Genome Evolution in Culicinae Mosquitoes
… assembly indicated the presence of multiple chromosomal inversions between them. To better understand population structure and chromosome evolution in Culicinae mosquitoes, especially in the Culex pipiens complex, we studied genomic and chromosomal differentiation between two subspecies Cx. …

Studies on Selection in Natural and Experimental Populations of Drosophila Pseudoobscura
… possibilities are discussed. The system of inversions on the third chromosome is shown to be independent of that on the X-chromosome. One of the commonest geographic variations of insects is that of body size with temperature, the genetically larger strains coming from the cooler regions. …
