  2. 1. The use of museum specimens in conservation genomics

    Author : Johanna von Seth; Love Dalén; Karin Norén; Gernot Segelbacher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conservation genomics; museum specimens; genomic erosion; diversity; inbreeding; mutational load; genetic drift; purging; population divergence; local extinction; population decline; Sumatran rhinoceros; kakapo; arctic fox; Chatham Island black robin; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : In the face of an increasing number of species being threatened by extinction, museum collections can constitute a powerful resource for acquiring genomic data of endangered taxa. By utilising datasets that combine genomes from present-day populations with those from historical timepoints, several questions relevant for conservation can be investigated. READ MORE

  4. 2. The age of museomics : How to get genomic information from museum specimens of Lepidoptera

    Author : Elsa Call; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Museomics; Museum specimens; Lepidoptera; WGS; Target enrichment; Phylogenomics; NGS;

    Abstract : In the age of museomics, the ability to sequence the genetic material from old museum specimens provides an invaluable and often untapped molecular resource. The application of the latest Next-Generation sequencing (NGS) technologies to such specimens allows us to utilise the diverse biobank that is natural history museums. READ MORE

  5. 3. Studies of declining populations - temporal genetic analyses of two arctic mammals

    Author : Veronica Nyström; Anders Angerbjörn; Lisette Waits; Stockholms universitet; []
    Keywords : Vulpes lagopus; Mammuthus primigenius; population reduction; extinction; ancient DNA; mitochondrial DNA; microsatellites; genetic variation; NATURAL SCIENCES; NATURVETENSKAP; zoologisk ekologi; Animal Ecology;

    Abstract : Many populations and species are threatened with extinction today. Understanding the extinction process and the factors behind population decline is therefore important. READ MORE

  6. 4. Exploring Fennoscandian agricultural history through genetic analysis of aged crop materials

    Author : Maria Lundström; Jenny Hagenblad; Matti W. Leino; Mattias Jakobsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Crop plants have undergone a multitude of genetic changes during and following their domestication. The spread of agriculture brought the crops to new geographic regions exposing them to new environments and selection pressures along the way. READ MORE

  7. 5. Ancient DNA as a Means to Investigate the European Neolithic

    Author : Helena Malmström; Anders Göterström; Gunilla Holmlund; T Brown; Uppsala universitet; []
    Keywords : Molecular genetics; aDNA; contamination; authentication; mtDNA; Neolithisation; Genetik;

    Abstract : The transition from a hunter-gatherer lifestyle to a farming lifestyle, i.e. the Neolithisation, is arguably the most important event in human prehistory. While the geography and dating of the Neolithisation is well known, the process is still under debate, especially if it occurred through diffusion of ideas or with migrating farmers. READ MORE
