  2. 1. Survival of the Tamest : The Domesticated Phenotype in Red Junglefowl Selected for Tameness

    Author : Rebecca Katajamaa; Per Jensen; Dominic Wright; Ruth C. Newberry; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; domestication; chicken; red junglefowl; tameness; brain size; behaviour; cognition; body size;

    Abstract : Early animal domestication was probably associated with reduced fear of humans. Domestication is a process in which animals adapt to humans and the captive environment provided by humans. Selection on tameness as the only trait has previously been found to generate changes in other phenotypes in different animal species. READ MORE

  4. 2. Tame representations in Topological Data Analysis: decompositions, invariants and metrics

    Author : Francesca Tombari; Wojciech Chachólski; Patrizio Frosini; Peter Bubenik; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; topological data analysis; tameness; decompositions; invariants; metrics; Matematik; Mathematics;

    Abstract : This thesis is a compilation of results that can be framed within the field of applied topology. The starting point of our study is objects presenting a possibly complex intrinsic geometry. The main goal is then to simplify, without trivializing, the geometric information characterising these objects by choosing an appropriate representation.

  5. 3. 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

  6. 4. Early domestication? : Phenotypic alterations of Red Junglefowl selected for divergent fear of humans

    Author : Beatrix Agnvall; Per Jensen; Hannah Rowland; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Domestication is the process through which animals adapt to conditions provided by humans. The domesticated phenotype differs from wild ancestors in a number of traits relating to physiology, morphology and behaviour. READ MORE

  7. 5. Exploring Brain Gene Expression i Animal Models of Behaviour

    Author : Julia Lindberg; Elena Jazin; Peter Saetre; Jonathan Flint; Uppsala universitet; []
    Keywords : Biology; behavioural genetics; gene expression; brain; microarray analysis; domestication; animal model; haem; Canis familiaris; Vulpes vulpes; Mus musculus; Biologi;

    Abstract : The genetic basis for behavioural traits is largely unknown. The overall aim of this thesis was to find genes with importance for behavioural traits related to fear and anxiety. Microarray analysis was used to screen expression profiles of brain regions important for emotional behaviour in dogs, wolves, foxes and mice. READ MORE
