1. Restaurering av grässandhedar genom aktiv markstörning - en jämförelse av florans kolonisation av plöjningar och sandblottor på Revingefältet utanför Lund
Master-uppsats, Lunds universitet/Examensarbeten i biologiSammanfattning : The conservation value of sandy habitats for a flora and fauna adapted to open, light, dry, warm, and often nutrient-poor conditions, is well recognized. Today this environment is threatened by lack of disturbance, fragmentation and exploitation, acidification and increased levels of nitrogen and phosphorus. LÄS MER
2. Modelling the Water Table in a Bog
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

3. Ectomycorrhizal fungi community shift along gradient from forest to clearcut : two field seasons after harvest of old growth Scots pine forests
Master-uppsats, SLU/Dept. of Forest Mycology and Plant PathologySammanfattning : It is known that the number of ECM decline and the community composition is altered by clearcutting. This study aims to investigate impacts at a more detailed scale. LÄS MER
4. Modelling and Validation of Evaporation Systems; Mass & Energy Balances
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : To evaluate the performance of evaporation systems, performance parameters such as overall heat transfer coefficient and evaporation rate need to be evaluated. These parameters are difficult measure and therefore need to be calculated using other measured data. LÄS MER
5. Hydrological control of plant species composition and distribution in Dal River alluvial meadows
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Northern boreal alluvial meadows are ecologically significant semi-natural ecosystems within the riparian zone. The effects of disturbance like flooding, grazing, and mowing have historically maintained high nutrient turnover and succession disruption that led to high biodiversity, leading to their inclusion in the Natura 2000 network.
