  1. 16. How elephants utilize a miombo-wetland ecosystem in Ugalla landscape, Western Tanzania

    Författare :Elikana Kalumanga; Sara Cousins; Steve Lyon; Jan Bengtsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Browsing; Elephants; Forage; GPS collars; Mineral elements; Miombo woodlands; Protected areas; Termite mounds; Ugalla; Water hyacinth; Woody plants abundance; Physical Geography; naturgeografi;

    Sammanfattning : African elephants are ‘keystone’ species with respect to biodiversity conservation in Africa since they maintain habitats that support several animal communities by changing vegetation structure through foraging and by dispersing seeds between landscapes. Elephants are also ‘flagship’ species because, given their impressive size, they can make people sympathetic and stimulate local and international concerns for their protection. LÄS MER

  3. 17. Radionuclide transport in the boreal landscape : Uranium, thorium and other metals in forests, wetlands and streams

    Författare :Fredrik Lidman; Hjalmar Laudon; Köhler Stephan; Oleg Pokrovsky; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; uranium thorium metal transport radionuclide wetland forest stream peat mire; naturgeografi; Physical Geography;

    Sammanfattning : The boreal landscape is complex mosaic of vast forests, lakes and wetlands. Through the landscape flows a fine network of streams and rivers, carrying dissolved and suspended material from atmospheric deposition and weathering of soils and bedrock to downstream recipients.

    Sammanfattning : In recent decades, Rwanda has been affected by the loss and fragmentation of natural habitats for native species of animals and plants. As a consequence, landscape connectivity—i.e. LÄS MER

  5. 19. Artificial neural networks : applications in morphometric and landscape features analysis

    Författare :Amir Houshang Ehsani; Fredrich Quiel; Wolter Arnberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik;

    Sammanfattning : In this thesis a semi-automatic method is developed to analyze morphometric features and landscape elements based on Self Organizing Map (SOM) as a unsupervised Artificial Neural Network algorithm. Analysis and parameterization of topography into simple and homogenous land elements (landform) can play an important role as basic information in planning processes and environmental modeling.

  7. 20. Planning in the 'New Reality' : Strategic Elements and Approaches in Swedish Municipalities

    Författare :Charlotta Fredriksson; Göran Cars; Raine Mäntysalo; KTH; []
    Nyckelord :planning theory; planning practice; municipality; region; comprehensive planning; strategic planning; forum-arena-court; case study; planeringsteori; planeringens praktik; kommun; region; översiktsplanering; strategisk planering; forum-arena-court; fallstudie;

    Sammanfattning : Central to this dissertation is a discourse in contemporary Swedish planning practice referred to as the ‘new reality’. The name of this discourse reflects the notion that planning practice interprets the conditions of today as differing from those which occurred previously. LÄS MER
