  1. 6. Nutrient distribution by mammalian herbivores in Hluhluwe-Imfolozi Park (South Africa)

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Laura van Veenhuisen; [2018]
    Nyckelord :megaherbivores; nutrient distribution; stoichiometry; South Africa; Hluhluwe–Imfolozi Park; African savannah; herbivores; wildlife ecology; dung;

    Sammanfattning : African megaherbivores are ecosystem engineers, which are under threat of extinction caused by, among others, poaching and climate change. Their current rates of loss means that there’s a need to better analyse their impact on the environment, in order to predict the consequences of losing this group. LÄS MER

  3. 7. A sneak peek on the upcoming results of the comparison studies regarding the declining Lesser Spotted Woodpecker (Dendrocopos minor) in Scania, Sweden

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Natalie Danielsson; [2018]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : In recent years the populations of the lesser spotted woodpecker (Dendrocopos minor) has been declining in Sweden. Many other species, like for example the marsh tit (Poecile palustris), depend on woodland structures that the lesser spotted woodpecker creates such as nesting holes. LÄS MER

  4. 8. Distribution of Meiofaunal biodiversity and abundance in relation to development stage of the Mangrove Forest

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Matilda Hultman; [2017]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Mangrove ecosystems constitute a valuable economic resource harbouring a wide diversity of organisms and operating an essential provider of nutrients for adjoining marine ecosystems. The meiobenthic fauna (i.e. LÄS MER

  5. 9. The Establishment of Macrobenthic Faunal Communities in Planted Mangroves of Increasing Age

    Kandidat-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Simon Jacobsen Ellerstrand; [2017]
    Nyckelord :Benthos; Shannon-diversity; forestation; biodiversity; ecosystem engineers; development issues; Biology and Life Sciences;

    Sammanfattning : The mangrove ecosystem is a tropical coastal community inhabited by organisms adapted to the stressful environment of the tidal zone. Mangrove ecosystems has in recent years been noted for the important ecosystem services they offer. LÄS MER

  7. 10. The effect of environmental and disturbance factors on the presence of different crab species in Pranburi Forest Park, Thailand

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Johanna Rosenquist; [2017]
    Nyckelord :mangrove forest; Thailand; biodiversity; canopy shade; water depth; human disturbance; Brachyura; Scylla serrata; Uca vocans; Sesarma mederi; Perisesarma bidens;

    Sammanfattning : The mangrove forest is one of the world’s most threatened ecosystems today and they have decreased significantly in Southeast Asia over the past 40 years. Brachyura (crabs) are important for this ecosystem and they function as ecosystem engineers with their burrowing activities that affects the soil and carbon uptake. LÄS MER
