  1. 1. The Physiology of Chicken Domestication : Involvement of the HPA-axis and the Autonomic Nervous System

    Författare :Magnus Elfwing; Jordi Altimiras; Michael Axelsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Domestication; chickens; HPA-axis; autonomic nervous system; heart rate; allometry;

    Sammanfattning : Domesticering är en urvalsprocess för önskvärda egenskaper hos djur som över tid förändrar deras utseende, beteende och genetik. Några exempel av djur som genomgått denna riktade avel är vargen, mufflon, uroxen, vildsvinet och den röda djungelhönan som vi idag känner som hunden, fåret, kon, grisen och slaktkycklingen. LÄS MER

  3. 2. Beastly Lessons: Natural Utopias in Seventeenth-Century England

    Författare :Sandra Iren Kottum; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; theriophily; animals; nature; utopias; emblems; empiricism; anthropocentrism; language of nature; beast literature; malleability; politics; animal exemplarity; animal language; colonialism; vegetarianism; early modern zoology; Leviticus; Royal Society; bestiaries; fables; The Parly of Beasts; The Blazing World; The Way to Health; James Howell; Margaret Cavendish; Thomas Tryon; early modern England; Golden Age; paradise; misanthropy; ecocriticism; self-fashioning;

    Sammanfattning : The present study investigates the motif of virtuous animal instructors in three selected English texts from the second half of the seventeenth century: James Howell’s The Parly of Beasts (1660), Margaret Cavendish’s The Blazing World (1666), and Thomas Tryon’s The Way to Health (1683). These authors proposed solutions to the challenges facing early modern England, most notably the Civil War, the emerging empirical science, and the incipient colonization of the Americas. LÄS MER

  4. 3. Large carnivore population turnover and ecological change during the Late Quaternary

    Författare :Erik Ersmark; Love Dalén; Jennifer Leonard; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : The cave lion (Panthera spelaea), the grey wolf (Canis lupus) and the brown bear (Ursus arctos) all shared an intercontinental distribution across the northern hemisphere during most of the Late Quaternary, and experienced repeated events of climate change. The cave lion went extinct at the end of the Pleistocene and although the wolf and the bear have survived until present day, recent human persecution has caused demographic bottlenecks and local extinctions.

  5. 4. The use of museum specimens in conservation genomics

    Författare :Johanna von Seth; Love Dalén; Karin Norén; Gernot Segelbacher; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conservation genomics; museum specimens; genomic erosion; diversity; inbreeding; mutational load; genetic drift; purging; population divergence; local extinction; population decline; Sumatran rhinoceros; kakapo; arctic fox; Chatham Island black robin; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : In the face of an increasing number of species being threatened by extinction, museum collections can constitute a powerful resource for acquiring genomic data of endangered taxa. By utilising datasets that combine genomes from present-day populations with those from historical timepoints, several questions relevant for conservation can be investigated. LÄS MER
