  1. 16. Genome size and phenotypic plasticity in the seed beetle, Callosobruchus maculatus

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Jesper Boman; [2017]
    Nyckelord :seed beetle; genome size; genome evolution; phenotypic plasticity;

    Sammanfattning : It has long been evident that genome size is not an accurate measure of organismal complexity. This paradox was “solved” with the discovery of nonfunctional and selfish DNA in the 1970s. However, emerging from this explanation was an enigma of complexity. LÄS MER

  3. 17. The role of serotonin in animal personality

    Kandidat-uppsats, Linköpings universitet/Biologi

    Författare :Fredrika Rasmussen; [2017]
    Nyckelord :5-HT; aggression; animal personality; animal personality dimensions; behavioural syndrome; serotonin;

    Sammanfattning : Interindividual differences in animal behaviour that are relatively consistent over time and context are referred to as animal personality. Personality has been recognized throughout the entire animal kingdom, in an array of species like molluscs, arthropods, fish, birds and mammals. LÄS MER

  4. 18. Variation in tameness among red junglefowls (Gallus gallus) induces variation in activity related behaviours : Exploring the basis of early domestication

    Kandidat-uppsats, Linköpings universitet/Biologi

    Författare :Ida Sörensen; [2016]
    Nyckelord :activity; behaviour; comfort; domestication; exploration; Gallus gallus; preening; tameness;

    Sammanfattning : The mechanisms behind early domestication of animals are still unknown and an important question is how the changes leading to what is called the domesticated phenotype have developed. It has been suggested that the domestication process has been based on tameness of animals, and that tameness is genetically correlated to other traits. LÄS MER

  5. 19. Dispersive trait expression of Asellus aquaticus from a rare cave habitat

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi; Linköpings universitet/Tekniska fakulteten

    Författare :Martin Brengdahl; [2016]
    Nyckelord :dispersal; dispersive traits; local adaptation; rare habitats; Asellus aquaticus;

    Sammanfattning : Dispersal influences several ecological and evolutionary processes, such as intraspecific competition, genetic drift and inbreeding. It can lead to phenotypic mismatch with the habitat when a locally adapted individual winds up in an environment with a divergent selection regime compared to the source habitat. LÄS MER

  7. 20. Genotypic and phenotypic variation of Phytopthora infestans on potato in the two Swedish regions Bjäre and Östergötland in 2015

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Ida Peterson; [2015]
    Nyckelord :potato late blight; mating type; simple sequence repeat markers SSR ; microsatellites; Multiplex PCR; sexual reproduction; asexual reproduction; aggressiveness; tests; population study;

    Sammanfattning : Potato late blight, caused by the oomycete Phytophthora infestans, is a very im-portant disease on potato, and one of the most devastating plant diseases in agri-culture worldwide. Despite the small area of potato in comparison with other cul-tivated crops, 40 % of the total use of fungicides in Sweden is used on potato. LÄS MER
