    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Dogs, Canis familiaris, share the lives of humans all over the world. That dogs, and the behavior of dogs, are of interest to many is therefore no surprise. In this thesis, the main aim has been to identify factors that affect dogs’ behaviours.The dog, Canis familiaris, is our first domesticated animal. LÄS MER

  3. 2. Detecting Signatures of Selection within the Dog Genome

    Sammanfattning : Deciphering the genetic basis of phenotypic diversity is one of the central aims of biological research. Domestic animals provide a unique opportunity for making substantial progress towards this goal. LÄS MER

  4. 3. Dog Ownership and Cardiovascular Disease

    Författare :Mwenya Mubanga; Tove Fall; Liisa Byberg; Erik Ingelsson; Unnur Valdimarsdottir; Uppsala universitet; []
    Nyckelord :dog ownership; cardiovascular risk; cardiovascular disease; pet ownership; Epidemiologi; Epidemiology;

    Sammanfattning : The relationship between pet ownership and human health has been studied extensively; however, the effect of dog ownership on human health has had conflicting results. The overall aim of this research project was to investigate the impact of dog ownership, and the death of the dog, on human cardiovascular health and all-cause mortality. LÄS MER

  5. 4. Early Experience, Maternal Care and Behavioural Test Design : Effects on the Temperament of Military Working Dogs

    Författare :Pernilla Foyer; Per Jensen; Martin Norsell; Daniel Mills; Försvarshögskolan; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Early experience; Maternal care; Dog; Military Working Dog; Behaviour; Temperament test; Stress; Försvarssystem; Military Technology;

    Sammanfattning : Domestication has resulted in animals with broad variations between as well as within breeds, which allows for the selection and breeding of animals for preferred traits. This selection has affected both the genotypes and phenotypes of animals. LÄS MER

  7. 5. Analysis of the origin and spread of the domestic dog using Y-chromosome DNA and mtDNA sequence data

    Författare :Mattias Oskarsson; Peter Savolainen; Ben Sacks; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mtDNA; domestication; Y-chromosome; SNP; ASY; dog; dingo;

    Sammanfattning : The domestic dog was probably the first domesticated animal, and the only one to spread to all continents in ancient times. The dog is one of the most phenotypically diverse animals, a result of human selection throughout dog history. LÄS MER
