  1. 11. Population dynamics of the spruce bark beetle Ips typographus in forest conservation areas and the interaction with biodiversity and natural enemies

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Evelina Andersson; [2023]
    Nyckelord :spruce bark beetle; population dynamics; conservation areas; biodiversity; natural enemies; species richness; managed forests; woodland key-habitats; nature reserves;

    Sammanfattning : Biodiversity is rapidly decreasing and in need of more conservation efforts. However, the tree-killing European spruce bark beetle, Ips typographus (L.), has made forest conservation controversial by affecting conservation areas and possibly adjoining managed forests, yet is still a keystone species leaving decaying wood promoting biodiversity.

  3. 12. The gut microbiome and nausea in pregnancy

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Clàudia González Valdivia; [2023]
    Nyckelord :Bioinformatics; Microbiome; Metagenomics; Genome analysis; Genetics;

    Sammanfattning : Nausea and vomiting are among the most common symptoms of early pregnancy. Its most extreme form Hyperemesis gravidarum often requires hospitalization and has been linked as a risk factor of perinatal depression. LÄS MER

  4. 13. Vilka naturvärden går att finna i nyligen återställda våtmarker i skogslandskap baserat på förekomsten av insekter?

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Johanna Melin; [2023]
    Nyckelord :Rewetting; wetlands; ditch blocking; ditching; insects; forest; species richness; Återvätning; våtmarker; dikespluggning; utdikning; insekter; skog; artrikedom;

    Sammanfattning : Svenska våtmarker har under flera hundra år dikats ut till förmån för odling av grödor och virkesproduktion. Idag ser verkligheten annorlunda ut och till förmån för klimatet satsar svenska staten nu pengar på att plugga igen diken och återställa dessa numera uttorkade våtmarker. LÄS MER

  5. 14. The Impact of Human Presence on Terrestrial Mammals in Secondary Regenerating Forest of the Peruvian Amazon

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Duncan Pandya; [2023]
    Nyckelord :Neotropics; camera traps; terrestrial mammals; human presence; species richness; diversity index;

    Sammanfattning : Human disturbance is becoming an ever-bigger threat to biodiversity across the globe and should continue to be a field of conservation priority. Urbanisation, research and tourism put unavoidable pressure on the surrounding flora and fauna, therefore we need to gain knowledge on how to reduce future harm. LÄS MER

  7. 15. Effects of soil factors on pioneer bryophyte species composition

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Dora Mijić; [2023]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.
