    Sammanfattning : The central nervous system (CNS) consists of an enormous number of cells, and large cellular variance, integrated into an elaborate network. The CNS is the most complex animal organ, and therefore its establishment must be controlled by many different genetic programs. LÄS MER

    Sammanfattning : The aim of the present thesis was to investigate hormonal and physiological effects in mothers during a breastfeeding session and in dogs and their owners in response to short-term interaction. In study one, sixty-six mothers receiving either exogenous oxytocin infusion and/or epidural analgesia (EDA) during labor or intramuscular oxytocin injection post partum were studied. LÄS MER

  3. 3. Effects of domestication related genes on behaviour, physiology and gene expression in chickens

    Författare :Anna-Carin Karlsson; Per Jensen; Randi Oppermann Moe; Linköpings universitet; []

    Sammanfattning : Domestication, the process when animals adapt to captivity, tends to modify a whole array of traits towards what has been termed “the domesticated phenotype”, where the domesticated animal differs from its wild ancestor in morphology, physiology, development and behaviour. Physiological traits and behaviours are controlled by genes. LÄS MER

  4. 4. Domestication Effects on the Stress Response in Chickens : Genetics, Physiology, and Behaviour

    Författare :Amir Fallahshahroudi; Per Jensen; Frank Albert; Linköpings universitet; []

    Sammanfattning : Animal domestication, the process where animals become adapted to living in proximity to humans, is associated with the alteration of multiple traits, including decreased fearfulness and stress response. With an estimated population of 50 billion, the domesticated chicken is the most populous avian species in the world. LÄS MER

  5. 5. Ontogeny and Population Biology of a Sex-Limited Colour Polymorphism

    Sammanfattning : This study has involved investigation of number of populations of the damselfly Ischnura elegans over several years, looking at frequency changes over time, morphological differences between the sexes and the morphs, differences in growth rate and development time, differences in fecundity between the morphs, and genetic differentiation between populations.
