  1. 1. Systematics and the evolution of flower symmetry of Posoqueria (Rubiaceae)

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Sebastián Giraldo Gómez; [2023-06-14]
    Keywords : Posoquerieae; Cinchonoideae; Ixoroideae; Dialypetalanthoideae; Angiosperms 353; target capture; Hybpiper; Pollen Catapult Mechanism.;

    Abstract : The genus Posoqueria is a Neotropical group of shrubs and trees in the coffee family Rubiaceae. Posoqueria is phylogenetically poorly understood and presents several internal taxonomical difficulties. READ MORE

  3. 2. Avelsarbetets roll i kampen mot antibiotikaresistenta bakterier : hur kan avel och genredigering reducera behovet av antibiotikatill produktionsdjur?

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Ebba Gustafsson; [2023]
    Keywords : antibiotikaresistens; avel; husdjur; selektion; bakteriell infektion; infektionsresistens; infektionstolerans; genredigering; genetisk markör; genom; CRISPR;

    Abstract : Antibiotikaresistenta bakterier utgör ett globalt hot för både sjukvård och livsmedelsproduktion då de begränsar möjligheten att behandla bakterieinfektioner hos både människor och djur. Förekomsten av resistenta bakterier växer globalt till följd av överflödig och felaktig användning av antibiotikapreparat. READ MORE

  4. 3. Detecting structural variants in the DNA of the inbred Scandinavian wolf

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Lars Huson; [2023]
    Keywords : animal; animal population; bioinformatics; biological sciences; biology; Canis lupus; CNV; conservation genetics; conservation genomics; copy-number variation; DNA; endangered population; endangered species; evolution; evolutionary biology; extinction; genetic diversity; genetics; genetic variation; genomes; genomics; grey wolf; inbreeding; inbreeding depression; indel; mutation; pedigree; population genetics; population genomics; Scandinavia; smoove; snakemake; structural variant; SV; wolf; wolves;

    Abstract : Only 40 years ago, just three individuals made the journey from Finland/Russia to found the current wolf population in the southwest of Sweden. This population, that to this date descends from less than 10 founders, has a substantial increased extinction risk due to inbreeding. READ MORE

  5. 4. Demography of Birch Populations across Scandinavia

    University essay from Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

    Abstract : Boreal forests are particularly vulnerable to climate change, experiencing a much more drastic increase in temperatures and having a limited amount of more northern refugia. The trees making up these vast and important ecosystems already had to adapt previously to environmental pressures brought about by the repeated glaciations during past ice ages. READ MORE

  6. 5. Effect of ascertainment bias on calculations of sex-biased admixture in Southern Africa

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Ragnheidur Diljá Ásmundsdóttir; [2021]
    Keywords : Evolutionary Biology; Population Genomics; Human Evolution;

    Abstract : Southern African populations harbour great genetic diversity enhanced by  population migration to the area in the last two millennia. Africa is perhaps the least studied continent in regards to population genetics and is often underrepresented in global studies. READ MORE
