  1. 1. Estimating the effective population size of Swedish native cattle : understanding the demographic trajectories of indigenous Swedish cattle breeds

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Dolapo Adepoju; [2022]
    Keywords : Swedish native cattle; effective population size; genetic drift; cattle demographic trajectories; native cattle conservation;

    Abstract : The indigenous cattle populations are on the decline globally with the continuous improvement of genetic gains in commercial breeds. Due to their unique adaptive features to the local ecosystem, traditional cattle breeds are pools of valuable genetic resources that could help combat the impact of climate change in the near future.

    Abstract : Amphibians globally are declining with roughly a third facing extinction due primarily to threats linked to human impacts. One way in which this is being combated is by captive breeding programs. READ MORE

  4. 3. Klimatförändringar och djurhälsa hos mjölkkor : framtida konsekvenser och utmaningar i Europa

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Sofia Carlsson; [2019]
    Keywords : klimatförändringar; mjölkko; värmestress; THI; embryoöverföring; klimatkänslig sjukdom; parasit; vektor;

    Abstract : Som en följd av den globala uppvärmningen förändras klimatet. Bland annat tros en ökad medeltemperatur och extrema väderförhållanden såsom värmeböljor bli alltmer frekventa runtom i Europa. Klimatförändringarna är något som i allra högsta grad påverkar lantbruket, inklusive mjölksektorn. READ MORE

  5. 4. Drivers of domestic cat movement in Scotland

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Fiona White; [2019]
    Keywords : Domestic cat; movement; Scotland; Scottish wildcat; conservation; GPS;

    Abstract : Free-roaming domestic cats are an increasing concern for biodiversity conservation. Cats prey on wildlife, spread disease and breed with native wildcat species leading to hybridisation. It is therefore useful to know what factors influence the movement of domestic cats. READ MORE

  6. 5. Genetisk variation hos allmogefår jämfört med andra nordiska raser

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Sofia Gundersen; [2018]
    Keywords : allmogefår; genetisk variation; nordiska kortsvansfår; bevarande; SNPs; mikrosatelliter; endogent retrovirus;

    Abstract : Genetisk variation är en viktig del i bevarandearbete. En låg genetisk variation är inte bra för en population och kan vara förödande för en liten population med en hög inavelsgrad. Det finns inget enkelt sätt att öka en populations genetiska variation och samtidigt hålla en ras ren. READ MORE
