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

    Författare :Johanna von Seth; Love Dalén; Karin Norén; Gernot Segelbacher; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 17. Hybridization and Evolution in the Genus Pinus

    Författare :Baosheng Wang; Xiao-Ru Wang; Sally Aitken; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adaptation; biogeography; coalescent simulation; cytoplasmic genome; demographic history; genetic diversity; hybridization; migration; Pinus; population structure; selection; speciation; evolutionär genetik; evolutionary genetics;

    Sammanfattning : Gene flow and hybridization are pervasive in nature, and can lead to different evolutionary outcomes. They can either accelerate divergence and promote speciation or reverse differentiation. The process of divergence and speciation are strongly influenced by both neutral and selective forces.

  4. 18. Inter and Intra-Assemblage Characterizations of Giardia intestinalis: from clinic to genome

    Författare :Johan Ankarklev; Staffan Svärd; Johanna P. Daily; Uppsala universitet; []
    Nyckelord :Giardia; protozoa; parasite infection; diarrhea; genome sequencing; comparative genomics; genotyping; ASH; MLG; Infektionssjukdomar; Infectious Diseases; Molekylär medicin; Molecular Medicine; Mikrobiologi; Microbiology;

    Sammanfattning : The protozoan parasite Giardia intestinalis (syn. G. lamblia, G. duodenalis) is one of the most common causes of diarrheal disease throughout the world, where an estimated 500 million people are infected annually. LÄS MER

  5. 19. Genomic dynamics over contemporary time frames in wild salmonid populations

    Författare :Sara Kurland; Linda Laikre; Kathryn Elmer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conservation genomics; genetic monitoring; whole-genome sequencing; metapopulation; salmonid; brown trout; effective population size; Pool-seq; genetic connectivity; intraspecific diversity; sympatric populations; populationsgenetik; Population Genetics;

    Sammanfattning : Genetic diversity is the foundation of all biological variation. An approach for sustainable use and protection of genetic diversity is continuous sampling over space and time, i.e. monitoring. LÄS MER

  7. 20. Constraint-based modeling of yeast metabolism and protein secretion

    Författare :Feiran Li; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein secretion; metabolism; yeast evolution; genome-scale metabolic model; phenotype diversity;

    Sammanfattning : Yeasts are extensively exploited as cell factories for producing alcoholic beverages, biofuels, bio-pharmaceutical proteins, and other value-added chemicals. To improve the performance of yeast cell factories, it is necessary to understand their metabolism. LÄS MER
