21. Mountain vegetation in the Faroe Islands in a climate change perspective
Sammanfattning : 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. LÄS MER
22. Global Changes and European Terrestrial Ecosystems
Sammanfattning : 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. LÄS MER
23. Development of a Detailed Geomorphological Mapping System and GIS Geodatabase in Sweden
Sammanfattning : 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).

24. An Optimisation Approach to Cartographic Generalisation
Sammanfattning : 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. LÄS MER
25. Gradients of time and complexity : understanding how riparian and instream ecosystems recover after stream restoration
Sammanfattning : 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. LÄS MER
