1. 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.

2. Bankens roll vid generationsskifte av skogsfastigheter : en studie av intressenters tjänstebehov
Master-uppsats, SLU/Dept. of Forest EconomicsSammanfattning : Sveriges totala landareal består av cirka 28 miljoner hektar skogsmark. Tillsammans äger cirka 311 000 privata skogsägare drygt 50 procent av den svenska skogsarealen. Ägarbyten bland dessa skogsfastigheter sker kontinuerligt. 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. 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
5. Recent expansion of the endangered beetle Plagionotus detritus in the greater Stockholm area
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Biodiversity is declining worldwide, and the biggest reason for this is habitat destruction. In Sweden one third of all the red listed species belongs in broadleaved deciduous forests. The most common reason for the endangerment of these species is the destruction of the deciduous forest.
