    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phenotypic plasticity; inducible defences; stress physiology; cortisol; immune function; trade-offs; sexual dimorphism; crucian carp; visual ecology; predator-prey interactions; POMC pro-opiomelanocortin ; colour change; eco-immunology; Anti-predator defences; Inducible morphological defence; Phenotypic plasticity; Stress physiology; Cortisol; Immune function; Crucian carp; Predator-prey interactions; Trade-offs; Sexual dimorphism; POMC; Pro-opiomelanocortin; Visual ecology; Eye evolution; Melanin; Eco-immunology; Pace-of-life; Behavioural plasticity;

    Abstract : Almost all species face some degree of predation risk, and, hence, evolution has produced a plethora of anti-predator defences. However, anti-predator strategies require resources, and the prevailing risk of becoming prey is influenced by many factors and rarely constant across time and space. READ MORE

  4. 2. Immunity & the butterfly : A functional genomic study of natural variation in immunity

    Author : Naomi L.P. Keehnen; Christopher W. Wheat; Brian Lazzaro; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; eco-immunology; functional genomics; transcriptomics; innate immunity; selection dynamics; melanization; phagocytosis; population genetics; Pieris napi; populationsgenetik; Population Genetics;

    Abstract : Butterflies are ubiquitous and abundant, occurring in a wide variety of environments that contain diverse microbial communities with varied pathogenic pressures. These pathogens and parasites present a constant threat to organisms, and have led to the evolution of complex and intricate immune responses. READ MORE

  5. 3. Eco-immunological studies of innate immunity in Mallards (Anas platyrhynchos)

    Author : Anu S. Helin; Jonas Waldenström; Edwin Veldhuizen; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Avian β-defensins AvBDs ; Avian gene expression; Host-pathogen interactions; Innate immunity; Mallard Anas platyrhynchos ; Myxovirus resistance gene Mx ; Retinoic acid inducible gene 1 RIG-I ; Avian β-defensins AvBD ; Genuttryck; Gräsand Anas platyrhynchos ; Immunförsvar; Immungener; Myxovirus resistant gene Mx ; Patogen; Retinoic acid inducible gene 1 RIG-I ; Ecology; Ekologi;

    Abstract : This thesis comprises two sections, both of which explore eco-immunology of the innate immune system of mallards (Anas platyrhynchos). The innate immune system serves a pivotal role as the first line of defense against invading pathogens, and is comprised of physical and chemical barriers. READ MORE
