  1. 1. Estimating Variant Intolerance for Genes of Cattle

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Simon Lanigan; [2024]
    Nyckelord :Genes; Cattle;

    Sammanfattning : Cattle play a crucial role in providing nutrition and economic stability worldwide. Threats to their health, particularly infectious diseases, and genetic mutations, can have profound implications for both animal and human livelihoods. LÄS MER

  3. 2. Scots pine (Pinus sylvestris L.) morphological variation in the Massif Central region, France. : A study of differences in traits between populations.

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Amanda Johansson; [2023]
    Nyckelord :;

    Sammanfattning : Scots Pine (P. sylvestris L.) has one of the largest distributions among trees in Eurasia. It is important both economically and ecologically, with a dominant role in forests ecosystems. LÄS MER

  4. 3. Effects of climate on phenology, flowering, and berry production of boreal forest understory plants

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Shakhera Akter Shimu; [2023]
    Nyckelord :Climate change; plant phenology; phenological traits; phenology change; cumulative temperature; phenotypic plasticity; genotypic variation;

    Sammanfattning : Climate is changing faster than it was predicted before and consequently its impact is highly visible on many types of ecosystems globally. Effects of changing climate on forests and the environment are leading to threats for all sorts of ecosystems. LÄS MER

  5. 4. Countergradient variation and compensatory growth in Moor frog (Rana arvalis) along a replicated latitudinal gradient

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Sohini Mallick; [2022]
    Nyckelord :moor frog; countergradient variation; compensatory growth; latitudinal gradient;

    Sammanfattning : For evolution to occur over time, it is necessary for animals and plants to show phenotypic variation. If the individuals within populations of a species do not show observable differences among themselves, there will be a lack of driving force for natural selection to act on and decide which characteristic gets inherited from one generation to the next.

  7. 5. Brain morphology and behavioural variation in relation to habitat and predation risk in minnows (Phoxinus phoxinus)

    Master-uppsats, Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Marina Gallego González; [2022]
    Nyckelord :brain size; Ecology; environmental complexity; European minnow; fish; geometric morphometrics; morphological divergence; phenotypic plasticity; schooling.;

    Sammanfattning : So far, research on inter- and intraspecific teleost brain plasticity across different freshwater environments has been widely conducted. However, insights of brain morphological variation on social and predator avoidance behaviours are lacking. LÄS MER
