1. 36. Conservation genomics in inbred Scandinavian wolves using bioinformatic methods

   Författare :Linnéa Smeds; Hans Ellegren; Giorgio Bertorelle; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conservation genomics; Canis lupus; bioinformatics; Y chromosome; admixture; genetic load; structural variation; GWAS; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : With the recent and unprecedented progress in retrieving DNA sequence information from a large number of individuals of any species, conservation genetic research has entered a new phase. Specifically, it has become possible to study how genomes of endangered species respond to reductions in population size. LÄS MER

3. 37. Speciation genetics of recently diverged species

   Författare :Venkat Talla; Niclas Backström; Nicola Nadeau; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Speciation; Leptidea; Lepidoptera; chiffchaff; Cryptic species; genome-scan; Diapause; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : Species differentiation can be a consequence of evolutionary forces including natural selection and random genetic drift. Patterns of genomic differentiation vary across the tree of life. This variation seems to be dependent on, for example, differences in genomic architecture and molecular mechanisms. LÄS MER

4. 38. Adaptive divergence in fission yeast : From experimental evolution to evolutionary genomics

   Författare :Sergio Ivan Tusso Gomez; Jochen B.W. Wolf; Simone Immler; Roger K. Butlin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptation; divergence; selection; experimental evolution; genomics; genome evolution; population genetics; fission yeast; phenotypic variation; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : How adaptation and population differentiation occur is fundamental to understand the origin of biodiversity. Work in speciation alongside the increased ease of generating genomic data have allowed the exploration of genomic changes relevant to adaptation. LÄS MER

5. 39. Gene regulatory evolution in flycatchers: statistical approaches for the analysis of allele-specific expression

   Författare :Mi Wang; Hans Ellegren; Christopher Wheat; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ASE; gene expression evolution; bayesian; RPASE; flycatcher.; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : Understanding the molecular mechanisms underlying evolutionary changes in gene expression is a major research topic in biology. While a powerful approach to study this is the analysis of allele-specific expression (ASE), most of previously published methods can only be applied to lab organisms. LÄS MER

7. 40. On the Evolution of Reproductive Systems in Neurospora

   Författare :Rebecka Strandberg; Hanna Johannesson; Paul Dyer; Uppsala universitet; []
   Nyckelord :Neurospora; mating type; pheromone receptor; phylogeny; gene expression; heterothallism; homothallism; pseudohomothallism; alternative splicing; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : The aim of this thesis was to study the evolution of reproductive systems and reproductive traits in the fungal genus Neurospora. More specifically, I have investigated the evolutionary forces shaping the genes involved in sexual reproduction, focusing on mating-type (mat) and pheromone receptor (pre) genes. LÄS MER
