1. Geomorphic change along the Rönne river : Effects caused by dams
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Many rivers can shape their path through the landscape with erosion and deposition where the riverbed and riverbanks both shape the direction and energy of the flow. The river flow can erode the riverbanks and create meanders which is when the river creates bends in its path that become increasingly curved. LÄS MER
2. Characteristics of instream wood following alluvial river restoration : Using Uncrewed Aerial Vehicles
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : River restoration is something that is often used to help restore watercourses that were historically used for timber floating. In these restorations, instream wood (IW) plays a big role in increasing biodiversity and habitat heterogeneity in watercourses. LÄS MER
3. VATTENLEVANDE FÅGLARS PÅVERKAN PÅ VEGETATIONEN I GRUNDA HAVSMILJÖER : FJÄRRANALYS SOM VERKTYG FÖR ATT IDENTIFIERA BETNINGSMÖNSTER
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Submerged aquatic vegetation (SAV) is an important source of food for waterfowl. Effects of waterfowl grazing on SAV has foremost been studied in freshwater and agricultural ecosystems. LÄS MER
4. Spatialanalys av markgeokemi : Hur utlakningshalter av markgeokemin varierar i Sveriges morän enligt interpolationsmetoder
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The purpose of this study was to evaluate the spatial distribution of geochemistry in Swedish till and whether interpolations could predict unknown values of geochemistry between samples at a national spatial level, Sweden, and a regional, the county of Västerbotten. The information of the spatial distribution of the elements and the interpolations accurateness has several applications. LÄS MER
5. Environmental factors affecting European spruce bark beetle (Ips typographus) outbreaks in Sweden : Linking AI-detected dead spruce, soil moisture, nature protection and bark beetle outbreak (Ips typographus) in Sweden
Master-uppsats, Karlstads universitetSammanfattning : Norway spruce (Picea abies) is a vital tree species in Sweden's extensive forested landscape. However, the planting of spruce beyond its natural range has made it vulnerable to pests like the spruce bark beetle (Ips typographus), which has caused substantial damage to Swedish forests. LÄS MER
