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
