  1. 6. Influence of surface water availability on the distribution of White Rhinoceros in central Greater Kruger

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

    Författare :Julie Mauguiere; [2022]
    Nyckelord :White Rhinoceros; Ceratotherium simum; water provisioning; artificial water; ecological processes; habitat selection; spatial ecology; landscape use; KNP; APNR; SAWC;

    Sammanfattning : The population of white rhinoceros (Ceratotherium simum simum) is now declining in the Kruger National Park (KNP) in South Africa due to the intense poaching crisis ongoing since the early 2000s. The need for an efficient conservation effort has never been greater and requires a better understanding of white rhinoceros distribution in the landscape. LÄS MER

  3. 7. Spatial resolution of methane production and ebullition in Lake Alsta

    Master-uppsats, Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Evelina Hiltunen; [2021]
    Nyckelord :methane; ebullition; TN;

    Sammanfattning : Freshwater ecosystems cover about 4 % of the Earth’s surface. Yet they are important components in the global C cycle, as they in addition to their within-lake primary production, receive and process organic matter loads originating from terrestrial environments. The boreal forest biome has the highest density of lakes globally. LÄS MER

  4. 8. Temporal Trends in Dissolved Inorganic Carbon in a Swedish Boreal Catchment

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Lukas Rehn; [2021]
    Nyckelord :Boreal catchments; carbon cycling; carbon dioxide; DIC; headwater streams; Krycklan Catchment Study; trend analysis;

    Sammanfattning : Inland waters are important systems for transforming, storing and transporting carbon along the aquatic continuum, but also by emitting carbon dioxide (CO2) and methane (CH4) to the atmosphere. In light of the last decades observed increase in dissolved organic carbon (DOC) in many inland waters across the northern hemisphere, a logical question arise whether other aquatic carbon species display similar trends.

  5. 9. Topographic controls of drought impact on Swedish primary forests

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Johanna Asch; [2021]
    Nyckelord :Physical geography; ecosystem analysis; primary forest; boreal forest; drought impact; topography; drainage; climate change; random forest; terrain index; Earth and Environmental Sciences;

    Sammanfattning : Anthropogenic climate change has increased the frequency of extreme drought events and leads to “hotter” droughts. Topography controls plant available water and site-specific climatic conditions. Drought sensitivity may therefore vary over short distances between wet and dry locations of the landscape. LÄS MER

  7. 10. Digitizing and Mapping Channel Heads Across Various Forested Regions in Sweden Using a High-Resolution DEM : A Regional Analysis of How Landscape Properties Influencing Channel Head Initiation

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Amanda Jarefjäll; [2021]
    Nyckelord :;

    Sammanfattning : Acting as a hydrological link between the terrestrial landscape and the larger downstream river network, channel heads and their immediate headwaters are essential geomorphological features in our landscape. Not only due to their ability to transport water and sediment and cycling of nutrients, but as an important component for ecosystem productivity and aquatic habitats. LÄS MER
