2. 1. Development and Application of Genomic Resources in Non-model Bird Species

   Author : Biao Wang; Jacob Höglund; Christopher Wheat; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; genome; transcriptome; next generation sequencing; non-model species; bioinformatics; reference guided assembly; RNA-Seq; comparative genomics; gene expression; major histocompatibility complex; single nucleotide polymorphism; microsatellite; Biologi; Biology;

   Abstract : Understanding the genetic basis of biological processes is a fundamental component of modern ecology and evolutionary biology studies. With the recent advent of next generation sequencing (NGS) technologies, it is now possible to perform large genome and transcriptome projects for ecologically important non-model species. READ MORE

4. 2. Genetic variation and inference of demographic histories in non-model species

   Author : Jean-Luc Tison; Dalén Love; Mats Grahn; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molekylärgenetik; Molecular Genetics;

   Abstract : Both long-term environmental changes such as those driven by the glacial cycles and more recent anthropogenic impacts have had major effects on the past demography in wild organisms. Within species, these changes are reflected in the amount and distribution of neutral genetic variation. READ MORE

5. 3. 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.

6. 4. Polyploid Phylogenetics in Plants: Insights on non-model organisms in Fabaceae and Malvaceae

   Author : Jonna S. Eriksson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Diploidization; genome duplication; haplotypes; Hibisceae; Hibiscus; homoeologues; high-throughput sequencing; Pavonia; Malvaceae; polyploidization;

   Abstract : Genome duplication is a common phenomenon in angiosperms and advances in sequencing technologies and bioinformatics is now revealing its prevalence and significance. In a polyploidization event all genes in a genome are doubled. READ MORE

7. 5. Inferring demographic history and speciation of grouse using whole genome sequences

   Author : Radoslav Kozma; Jacob Höglund; Jeff A. Johnson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Demographic history; speciation; effective population size; adaptation; willow grouse; red grouse; black grouse; rock ptarmigan; Tetraoninae; conservation genetics; climate change; PSMC; species distribution modelling; FOXP4; Agouti;

   Abstract : From an ecological perspective, knowledge of demographic history is highly valuable because population size fluctuations can be matched to known climatic events, thereby revealing great insight into a species’ reaction to past climate change. This in turn enables us to predict how they might respond to future climate scenarios. READ MORE
