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. Utveckling av barrträdsföryngringar markberedda med grävmarkberedning kontra harvning på blockrik skogsmark
Uppsats för yrkesexamina på avancerad nivå, SLU/Department of Forest Biomaterials and Technology (from 131204)Sammanfattning : Markberedning utförs på ungefär 90 % av den föryngrade arealen i Sverige varje år och utförs vanligtvis maskinellt med avsikt att bearbeta marken för att skapa goda förutsättningar för plantetablering. En icke obetydlig del av Stora Ensos markinnehav är på blockrik mark som är tekniskt svår att markbereda. LÄS MER
3. Fungal Effects on Tree Growth in a Primary Succession
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : In the Boreal zone, ectomycorrhiza is the most common mycorrhiza found among trees and helps with nitrogen and nutrient uptake. Most research on mycorrhiza, its effect, and community development are done on secondary succession (succession in an ecosystem after a disturbance) such as after a clearcut. LÄS MER
4. Exploring the factors affecting tree establishment after wildfire in a boreal forest in Sweden
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : The factors affecting tree establishment in boreal forests after fire will help determine the community composition of the regenerating forest. These may have large consequences on the community dynamics for years after the fire disturbance. LÄS MER
5. Effects of soil factors on pioneer bryophyte species composition
Master-uppsats, Lunds universitet/Examensarbeten i biologiSammanfattning : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.
