2. 1. Advances in studying the role of genetic divergence and recombination in adaptation in non-model species

   Author : Ramprasad Neethiraj; Christopher Wheat; Sören Nylin; Mathieu Joron; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Recombination; Genetic divergence; Lepidoptera; Genetic variation; Genetic diversity; Holocentric chromosomes; cis-regulatory variation; Allele-specific expression; populationsgenetik; Population Genetics;

   Abstract : Understanding the role of genetic divergence and recombination in adaptation is crucial to understanding the evolutionary potential of species since they can directly affect the levels of genetic variation present within populations or species. Genetic variation in the functional parts of the genome such as exons or regulatory regions is the raw material for evolution, because natural selection can only operate on phenotypic variation already present in the population.

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

   Author : Sergio Ivan Tusso Gomez; Jochen B.W. Wolf; Simone Immler; Roger K. Butlin; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

5. 3. Fishing the gene pool : Genetic structure, admixture and behavioural complexity in fisheries management

   Author : Kim H. Berndt; Enhet akvatisk ekologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fisheries management; Fishery stock; Stock discrimination; Genetic structure; Genetic admixture; Admixture zone; Stock substructure; Phenotypic divergence; Gadus morhua; Salmo trutta;

   Abstract : Prudent management of marine fish resources relies on separation and management of biologically meaningful groups of conspecifics, termed fishery stocks, often depicted as self-sustaining, spatiotemporally separated and demographically independent entities. Such stock discrimination has however proven challenging. READ MORE

6. 4. Ecological drivers and genetic signatures of evolutionary divergence and local adaptation in pike (Esox lucius)

   Author : Johanna Sunde; Anders Forsman; Anssi Laurila; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptation; differentiation; Esox lucius; evolution; gene flow; genetic admixture; genetic structure; microsatellites; pike; RADseq; salinity tolerance; temperature tolerance; Ecology; Ekologi;

   Abstract : The diversity among species, populations, and individuals in nature is astonishing. Genetic and phenotypic variation constitutes the raw material for evolution. It influences how populations respond to changing environments, and can impact long-term survival of species and ecosystem functioning. READ MORE

7. 5. Population Genetic Methods and Applications to Human Genomes

   Author : Lucie Gattepaille; Mattias Jakobsson; Kevin Thornton; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Population genetics; Human evolution; Genetic diversity; Genetic differentiation; Adaptation; Population structure; Effective population size; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Abstract : Population Genetics has led to countless numbers of fruitful studies of evolution, due to its abilities for prediction and description of the most important evolutionary processes such as mutation, genetic drift and selection. The field is still growing today, with new methods and models being developed to answer questions of evolutionary relevance and to lift the veil on the past of all life forms. READ MORE
