  1. 21. Bacteria in the vagina during the estrous cycle in mares

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Timjan Åkerholm; [2023]
    Nyckelord :artificial insemination; bacteriology; breeding; embryo transfer; equine reproduction; estrous cycle; ovulation; stud farm; vagina;

    Sammanfattning : An understanding of the normal bacterial flora of any organ is essential to provide the background to conditions and interventions that might cause the flora to change. In the vagina of the mare, a change of bacterial flora could be induced by introduction of semen, treatment with antibiotics, backflow from an unhealthy uterus etc. LÄS MER

  3. 22. 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. 23. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Marta Holmlund; [2023]
    Nyckelord :wetland restoration; vegetation; biodiversity; topsoil removal; Ellenberg indicator values;

    Sammanfattning : Wetlands are recognized as important types of ecosystems, inhabiting rich biodiversity and performing multiple ecosystem services. However, many have been lost because of anthropogenic activities and a majority of the remaining wetland habitats are in bad conditions, displaying both loss of functionality and biodiversity.

  5. 24. Relations between tree and habitat characteristics and the epiphytic lichen flora on oak : a case study from Lövön, Bohuslän

    Kandidat-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Julia Siegel; [2023]
    Nyckelord :Epiphytic lichens; Tree characteristics; Habitat characteristics; Oak; Biodiversity; Natural values; Light availability;

    Sammanfattning : Oak-rich forests and wooded pastures harbor diverse and distinct epiphytic lichen flora with many rare and threatened species. As these habitats have been subject to a substantial decline and degradation over the past centuries, oak woodlands have progressively come into focus for preservation. LÄS MER

  7. 25. The diversity of fungi in coniferous forests and mixed forests

    Master-uppsats, Karlstads universitet

    Författare :Ida Asplund; [2023]
    Nyckelord :Forest type; coniferous forest; mixed forest; fungi; fungal diversity; mycorrhiza; saprotrothic fungi; parasites; parasitic fungi; Skogstyp; barrskog; blandskog; svampar; svampdiversitet; svampmångfald; mykorrhiza; saprotrofiska svampar; parasiter; parasitiska svampar;

    Sammanfattning : The fungal domain has one of the highest biodiversities among eukaryotes and species within the domain fill important ecological roles, such as mutualistic mycorrhiza, decomposers, parasites and pathogens. The development of forest ecosystems and their related processes has not only been linked to fungal diversity but the composition and abundance of fungi benefits the abundance and diversity of other species as well.
