1. Brunifiering av akvatiska ekosystem: En experimentell studie som undersöker tröskelvärde för predator- och bytesförhållande vid en gradient från klart till brunt vatten
Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)Sammanfattning : Browning of water has increased over the last couple of decades on the northern hemisphere. Research show that possible drivers for this change are land use change, climate change, increased precipitation and increased temperatures. LÄS MER
2. Changes in July albedo and its relationship with EVI over the last two decades in the Swedish alpine region
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Vegetation in the subarctic is expected to respond to climate warming as its growth becomes less temperature limited. This has previously been recorded in the form of treeline advances and increasing shrub cover. Changes in vegetation cover may accelerate warming due to a decrease in summer albedo, in what is termed surface albedo feedback. LÄS MER
3. Kalknings påverkan och brunifiering av ytvatten i Västra Götalands län, Sverige : Drivande faktorer och trender
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : For more than 45 years an extensive liming measure has taken place in the southwest of Sweden in Västra Götaland county. The goal with the liming is to improve the aquatic ecosystems and counteract the acidification that has occurred in a large part of catchments in this area. LÄS MER
4. Modelling the Effects of Climate Change on Future DOC Export to Lake Mälaren Using a Generalized Watershed Loading Functions (GWLF) Model
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Browning of boreal freshwaters due to an increased export of terrestrial dissolved organic carbon (DOC) has been observed for some decennia. Drivers include recovery from acid deposition and changing climate and land cover. LÄS MER
5. How brownification and eutrophication effects a drinking water source – with Lake Bolmen, Sweden, in focus
Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)Sammanfattning : The ongoing human impact in form of deforestation, urbanization and intense agriculture is affecting the natural hydrology and our freshwater lakes negatively. Both eutrophication and brownification has seen to increase with the ongoing environmental change which can potentially have large impact on our freshwater ecosystems. LÄS MER
