  2. 1. Chicken domestication : Effects of tameness on brain gene expression and DNA methylation

    Author : Johan Bélteky; Per Jensen; Anna Kukekova; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Domestication greatly increases phenotypic variation in a short time span, with selection for a single phenotype and a plethora of associated phenotypic changes as an outcome of the process. The domestication process influences the underlying genomic architecture of a species, and the success and speed of the process is likely influenced by it. READ MORE

  4. 2. Domestication effects on foraging behaviour : consequences for adaptability in chickens

    Author : Christina Lindqvist; Per Jensen; Björn Forkman; Linköpings universitet; []
    Keywords : HUMANIORA; HUMANITIES; Etologi; chicken; domestication effects; behaviour; red jungle fowl RJF ; contrafreeloading CFL ; egg production; Ethnology; Etnologi;

    Abstract : The main aim of this thesis was to study domestication effects on foraging behaviour in chickens and to investigate whether and how domestication and selection for high production have influenced adaptability in chickens. Two domestic strains of chickens (egg layers and meat type chickens) and their wild ancestor, the red jungle fowl (RJF) were compared in different test situations with respect to foraging behaviour and adaptability.

  5. 3. Older People Meet Robots : Three Case Studies on the Domestication of Robots in Everyday Life

    Author : Susanne Frennert; Certec - Rehabiliteringsteknik och Design; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Older people; social robots; gerotranscendence; domestication theory; Participatory Design; social robotics;

    Abstract : This thesis explores how older people construct meaning, use and make sense of three kinds of robots in their homes. The exploration is undertaken in empirical studies of an assistive robot, an eHealth system, and robotic vacuum cleaners. READ MORE

  6. 4. Domestication of Brassica oleracea L

    Author : Lorenzo Maggioni; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Various theories exist about the progenitors of B. oleracea L. (cole crops) and the area of its domestication. Relatively recent molecular data have pointed at the wild species growing on the European Atlantic cliffs as the closest relatives to all the cultivated types. READ MORE

  7. 5. Response to wheat dwarf virus in wild and domesticated wheat : genetic resources of evolutionary and environmental origins

    Author : Jim Nygren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Wild and domesticated plants are constantly exposed to a variety of pathogens, which may trigger an arms race in evolution of defense strategies in the plant and development of virulence in the pathogen. The outcome of the interaction depends on the intensity of reciprocal selection between the interacting species, which may vary over space and time, explained as the geographic mosaic theory of coevolution.
