  1. 21. Zooplankton responses to multiple threats within and across generations

    Författare :Yongcui Sha; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Predation; Ultraviolet radiation; Daphnia; copepods; plasticity; maternal effects; adaptation; diel vertical migration;

    Sammanfattning : In their natural environments, organisms are unlikely to be distributed randomly but instead they are constantly faced with multiple and variable threats. In order to maximise survival, they need to be able to perceive the present threat level and respond accordingly. LÄS MER

  3. 22. Post-traumatic stress disorder and resilience in children of traumatised parents

    Författare :Atia Taufik Ismail Daud; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :PTSD; trauma; cognitive function; IQ; ADHD; resilience; Trauma Related Disorder; posttraumatic personality disorder;

    Sammanfattning : The main aim of this thesis was to explore the possible association between parents severe emotional trauma and their children's psychopathology (Transgenerational transmission of parents' traumatic experiences to their children), as well as resiliency factors and the relationship between prolonged traumatisation and personality development.

  4. 23. The Physiology of Chicken Domestication : Involvement of the HPA-axis and the Autonomic Nervous System

    Författare :Magnus Elfwing; Jordi Altimiras; Michael Axelsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Domestication; chickens; HPA-axis; autonomic nervous system; heart rate; allometry;

    Sammanfattning : Domesticering är en urvalsprocess för önskvärda egenskaper hos djur som över tid förändrar deras utseende, beteende och genetik. Några exempel av djur som genomgått denna riktade avel är vargen, mufflon, uroxen, vildsvinet och den röda djungelhönan som vi idag känner som hunden, fåret, kon, grisen och slaktkycklingen. LÄS MER

  5. 24. Developmental origins of polycystic ovary syndrome : role of early adverse life events on adult health

    Författare :Maria Manti; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The research focus of this thesis is polycystic ovary syndrome (PCOS), the most common endocrine disorder among women of reproductive age, associated with reproductive, cardio-metabolic, and mental health complications. Despite the high prevalence, little is known about the etiology of the syndrome. LÄS MER

  7. 25. Maternal programming: costs, benefits and constraints of maternal hormone transfer

    Författare :Michael Tobler; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; aves; immune function; behavior; Maternal effects; hormones;

    Sammanfattning : Avian mothers convey significant quantities of androgens (i.e. ?male? steroids) to their eggs, which are known to positively influence embryonic development, post-natal growth and competitive behaviour of the offspring. However, there is large inter-female variation in the amount of androgens transferred to the eggs. LÄS MER
