  2. 1. Genetics of equine insect bite hypersensitivity and genetic diversity in horses

    Author : Merina Shrestha; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Genetic variation contributing to the phenotypic variation was utilized in this thesis to understand the genetic background of a complex trait IBH, and to understand genetic diversity and relationships between various horse populations. IBH is the most common skin allergic disorder in horses, caused by bites of midges, predominantly Culicoides species. READ MORE

  4. 2. Anti-parasitic and anti-viral immune responses in insects

    Author : Olle Terenius; Ingrid Faye; Kenneth Söderhäll; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hemolin; Hyalophora cecropia; Antheraea pernyi; Drosophila melanogaster; anti-viral; anti-parasitic; rna interference; microarray; innate immunity; Genetics; Genetik;

    Abstract : Insects encounter many microorganisms in nature and to survive they have developed counter measures against the invading pathogens. In Drosophila melanogaster research on insect immunity has mainly been focused on infections by bacteria and fungi. READ MORE

  5. 3. Hemolin, a versatile immune protein from the Cecropia moth

    Author : Raul Bettencourt; Kenneth Söderhäll; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetics; genetik;

    Abstract : Insects have become useful models for the study of innate immune mechanisms, due to their lack of antibodies and receptors involved in adaptive immune response. However, the molecules and mechanisms involved in primordial immune recognition are still poorly understood. READ MORE

  6. 4. Coevolution and molecular background of species interactions in geographic mosaics

    Author : Xuyue Yang; Peter A. Hambäck; Michael R. Strand; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transcriptomics; population genetics; insect immunology; parasitoid; genome assembly; natural selection; Ecology and Evolution; ekologi och evolution;

    Abstract : In complex food webs, species often interact with each other indirectly through mediating species. As a result of geographic mosaic of coevolution, such interactions are often evolutionarily unstable and the traits governing the interaction sometimes vary over time. READ MORE

  7. 5. Drosophila Sensory Neuroethology

    Author : Suzan Mansourian; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; Vinegar Fly; olfactory system; hygrosensation; receptor; ancestral habitat;

    Abstract : Animals, like humans, need to perceive their surroundings via their senses in order to make sensible behavioral decisions, reproduce successfully, and survive. Animals are equipped with audition, vision, thermosensation, hygrosensation, mechanosensation, magnetoception, gustation, and olfaction, which detects physical and chemical changes in their habitats.
