  2. 21. Mountain vegetation in the Faroe Islands in a climate change perspective

    Author : Anna Maria Fosaa; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; klimatologi; marklära; Växtekologi; Fysisk geografi; climatology; cartography; pedology; geomorphology; climate change.; Physical geography; Raunkiær´s life-forms; biodiversity; Vegetation zones; plant communities; Plant ecology; kartografi; geomorfologi;

    Abstract : This thesis is a study of the mountain vegetation in the Faroe Islands based on five altitudinal transects sampled during the period 1999-2001. The vegetation was studied on the basis of plant communities, life-forms and biodiversity of vascular plant species and is discussed in a climate change perspective. READ MORE

  4. 22. Global Changes and European Terrestrial Ecosystems

    Author : Emmanuel Gritti; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; European species; Climatic risk; pedology; cartography; climatology; Fysisk geografi; geomorphology; Physical geography; Vegetation modelling; Pollen analysis; Plant invasion; geomorfologi; marklära; kartografi; klimatologi; Global Changes;

    Abstract : Global environmental changes are topics of important societal concern and current scientific interest. These changes are driven by many different forcing and feedbacks occurring at various time and geographic scales and are largely influencing the various Earth systems. READ MORE

  5. 23. Development of a Detailed Geomorphological Mapping System and GIS Geodatabase in Sweden

    Author : Marcus Gustavsson; Else Kolstrup; Harry Seijmonsbergen; Ian S. Evans; Uppsala universitet; []
    Keywords : Physical geography and sedimentology; Geomorphology; Geomorphological map; GIS; Sweden; Naturgeografi och sedimentologi;

    Abstract : This thesis presents a method for detailed landscape presentation. The method incorporates both fieldwork-based comprehensive geomorphological description and digital data handling and thus contributes in filling the gap between traditional geomorphological mapping and modern geomorphological studies performed in Geographic Information Systems (GIS).

  6. 24. An Optimisation Approach to Cartographic Generalisation

    Author : Lars Harrie; Centrum för geografiska informationssystem (GIS-centrum); []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; incremental generalisation; multiple representation; least-squares method; optimisation; cartographic constraints; displacement; cartographic generalisation; graphic generalisation; map production; object-oriented spatial databases; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Technological sciences; Teknik;

    Abstract : Cartographic generalisation is the process of simplifying a representation to suit the scale and purpose of a map. As such, generalisation has always been a central part in map production. This thesis is a contribution to the ongoing work on automating cartographic generalisation. READ MORE

  7. 25. Gradients of time and complexity : understanding how riparian and instream ecosystems recover after stream restoration

    Author : Eliza Maher Hasselquist; Christer Nilsson; Stewart Rood; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioassessment; biodiversity; boreal; bryophyte; chronosequence; complexity; diatom; geomorphology; habitat heterogeneity; hydromorphological; macroinvertebrate; macrophyte; nitrogen cycling; river restoration; riparian buffer; stable isotopes; succession; Sweden; Environmental Science; miljövetenskap;

    Abstract : Why evaluations of the ecological outcomes of stream and river restoration have largely reported inconclusive or negative results has been the subject of much debate over the last decade or more. Understanding the reasons behind the lack of positive results is important for bettering future restoration efforts and setting realistic expectations for restoration outcomes. READ MORE
