    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Eirini - Lamprini Daouti; [2017]
    Keywords : Golden eagle; population ecology; breeding; survival; Aquila chrysaetos;

    Abstract : Successful conservation and management of Golden Eagle (Aquila chrysaetos) requires an in-depth understanding of its’ demographic parameters. The species in Sweden is listed as Near Threatened and threats include increasing demands for renewable energy, collisions with railways, illegal persecution, and lead poisoning. READ MORE

  3. 12. Life history trade-offs in Anadromous Burbot Lota lota (Linnaeus 1758) from Rickleån and Sävarån, Northern Sweden

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Mikael Sandberg; [2015]
    Keywords : life history trade-offs; anadromous burbots; Bothnian Bay; Rickleån; Sävarån; otoliths;

    Abstract : Anadromous burbots Lota lota (Linnaeus 1758) from two similar rivers in the Gulf of Bothnia area, Sävarån and Rickleån, Northern Sweden, were compared. The aim was to test for and explain differences in ecology. Spawning burbots in Sävarån were smaller, younger, grew slower and were more densely populated. READ MORE

  4. 13. Habitatmanipulering, en tveeggad bekämpningsmetod? : potentiella möjligheter och risker med alternativa födoresurser och skyddande habitat

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Hampus Åkerman Hoffman; [2015]
    Keywords : biologisk bevarande bekämpning; habitatmanipulering; skyddande habitat; alternativa födoresurser;

    Abstract : Bevarande biologisk bekämpning är en bekämpningsstrategi som används för att bevara eller öka mängden av en specifik naturlig fiende till den skadeorganism som ska bekämpas. En skillnad i jämförelse med andra strategier inom biologisk bekämpning är att inga biologiska bekämpningsorganismer tillförs, i stället främjas de naturliga fiender som redan finns i odlingen och det omgivande landskapet.

  5. 14. Sugar host preferences in adult Anopheles coluzzii : dry season plant selection in Burkina Faso

    University essay from SLU/Dept. of Ecology

    Author : Louise Malmgren; [2015]
    Keywords : malaria; Burkina faso; dry season; Anopheles; Culex; Anopheles gambiae; Anopheles coluzzii; sugar source selection; preference; preference ranking; Delonix regia; Carica papaya; Mangifera indica; Thevetia neriifolia; Jatropha curcas; Azadirachta indica; Banana musa; probing; feeding; perching;

    Abstract : Human plasmodian species, transmitted by mosquitoes of the genus Anopheles, are still one of the leading causes of human mortality in Sub-Saharan Africa. To supplement current vector control strategies, more knowledge about mosquito ecology is required. Central to studies is how malaria vectors relate to their blood hosts. READ MORE

  6. 15. Effect of diet and density on larval immune response and larval and adult host-preference in Spodoptera littoralis

    University essay from SLU/Dept. of Plant Protection Biology

    Author : Sophie Chattington; [2015]
    Keywords : artificial encapsulation; Egyptian cotton leafworm; immune response; innate preference hierarchy; larval density; larval development; larval memory; oviposition choice; phenoloxidase; Spodoptera littoralis; Y-tube;

    Abstract : Polyphagy presents difficulties to an insect, especially in terms of host choice. The adult insect must choose from a large number of possible host plant species, something which is considered to require extensive neural capacity to process. READ MORE
