  1. 1. Genomic selection and genome-wide association studies to dissect quantitative traits in forest trees

    Författare :Biyue Tan; Pär K. Ingvarsson; Björn Sundberg; Harry X. Wu; Dario Grattapaglia; Xiao-Ru Wang; Leopoldo Sanchez; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Genomic prediction; genome-wide association study; additive effects; dominance effects; epistasis effects; realized relationship matrix; Eucalyptus grandis; Eucalyptus urophylla;

    Sammanfattning : The convergence of quantitative genetics of complex traits with genomic technologies is quickly becoming an innovative approach to explore fundamental genetic questions and also have practical consequences for implementations in tree breeding. In this thesis, I used genomic selection and genome-wide association studies (GWAS) to dissect the genetic basis of quantitative traits, i. LÄS MER

  3. 2. Behavioural and Neuroendocrine Effects of Stress in Salmonid Fish

    Författare :Øyvind Øverli; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Aggression; Behaviour; Brain; Coping; Cortisol; Dominance; Dopamine; Feeding; Hierarchy; Norepinephrine; Responsiveness; Serotonin; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : Stress can affect several behavioural patterns, such as food intake and the general activity level of an animal. The central monoamine neurotransmitters serotonin, dopamine, and norepinephrine are important in the mediation of both behavioural and neuroendocrine stress effects. LÄS MER

  4. 3. Evolutionary consequences of dominance at the Brassicaceae self-incompatibility locus

    Författare :Jörg Alexander Bachmann; Tanja Slotte; Vincent Castric; Ove Eriksson; Pär Ingvarsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Capsella; mating system shift; self-fertilization; self-incompatibility; small RNA; dominance; Arabidopsis; population genetics; genomics; gene expression; ekologi och evolution; Ecology and Evolution;

    Sammanfattning : Self-incompatibility (SI) is a genetic mechanism that allows plants to enforce outcrossing by rejecting self-pollen and pollen from close relatives. In the Brassicaceae, SI is sporophytic and controlled by the self-incompatibility locus (S-locus). LÄS MER

  5. 4. Underlying psychological mechanisms of helping effects : Examining the when × why of charitable giving

    Författare :Arvid Erlandsson; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; charitable giving; helping; prosocial behavior; helping effects; identified victim effect; proportion dominance effect; in-group effect; emotions; sympathy; perceived utility; perceived responsibility; decision modes; mediation; moral decision making; dual-process theories.;

    Sammanfattning : The overarching purpose of this thesis was to investigate if different helping effects can be specifically linked to different psychological mechanisms. Helping effects (i.e. the when of helping) refer to situational differences that can increase or decrease the probability of helping. LÄS MER

  7. 5. Nandrolone decanoate, behaviour and brain: animal experimental studies

    Författare :Ann-Sophie Lindqvist; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Agression; alcohol intake; anabolic steroids; dominance; ethanol intakie; fleeing and freezing behaviours;

    Sammanfattning : Abstract: Abuse of anabolic androgenic steroids (AAS) has been linked to psychiatric and physiological complications in humans. Studies have further found a relationship between AAS abuse and abuse of alcohol and other drugs. LÄS MER
