    Sammanfattning : Biological evolution is part of the syllabi for Biology and Science in Swedish upper secondary school. In the syllabi, evolution is not only presented as a topic in Biology courses, but is also regarded as a unifying theme. The teacher has a fundamental role in deciding how the national curriculum is translated into the educational situation. LÄS MER

  2. 2. Hitting the mark studies of alterations in behaviour and fertility in ethinyl estradiol-exposed zebrafish and search related biomarkers

    Detta är en avhandling från Örebro : Örebro university

    Sammanfattning : In this thesis, we have analysed the effects of EE2 on non-reproductive behaviours and fertility. We have showed that two doses of EE2 in male adult short-term exposures evokes opposite behaviours in the novel tank test. LÄS MER

    Sammanfattning : 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. LÄS MER

  4. 4. Domestication and early experiences in chickens Behavior, stress and gene expression

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Pia Katrine Løtvedt; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A number of animal species have undergone domestication, the process of becoming adapted to living in captivity and in proximity to humans. Common for these species is that they have all developed certain traits, including changes to coat color, body size and level of fearfulness. This has been termed the domestic phenotype. LÄS MER

  5. 5. Deciduous tree occurrence and large herbivore browsing in multiscale perspectives

    Detta är en avhandling från Karlstad : Karlstad University

    Författare :Gunilla Cassing; Karlstads universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aspen; rowan; sallow; GIS; browsing; landscape; forest management; Biology; Biologi;

    Sammanfattning : Aspen ( Populus tremula), rowan (Sorbus auquparia) and sallow (Salix caprea) are deciduous tree species of low economic value for forestry and contribute to biodiversity of boreal forests. The species are rare in managed forest landscapes, and severely browsed by moose. LÄS MER
