21. Beetle Diversity – Land Sparing or Land Sharing? : the effects of timber extraction and restoration method on saproxylic beetle assemblages in mature managed pine forests
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : The impoverishment of saproxylic beetle communities is a growing concern for management of boreal forest biodiversity. Past research has found active restoration methods, such as creating deadwood and conducting prescribed burnings, to have a short-term positive effect on the species richness and compositional diversity of saproxylic beetle assemblages.

22. Dagvatten som berikar : en gestaltning av stadsdelsparken Ekebydalen i Uppsala innefattande integrering av dagvattenanläggningar och sociotopvärden
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Urban and Rural DevelopmentSammanfattning : Klimatförändringarna leder till skyfall och en ökad risk för översvämningar i våra städer som därmed behöver klimatanpassas för att hantera detta. Kravet på en hållbar dagvattenhantering ökar vilket innebär att vattnet fördröjs och renas på ett sätt som är inspirerat av naturen. LÄS MER
23. 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
24. The impact of forest management methods on the ectomycorrhizal community and implications for forest productivity in needleleaf forests
Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)Sammanfattning : Ectomycorrhizal fungi (ECM) form symbiotic relationships with trees by connecting to the roots, procuring soil nutrients in exchange for carbohydrates, and are an important contributor to plant growth. The forestry practice of clearcutting can be detrimental to the ECM community by removing its source of energy and creating unfavorable soil conditions, acutely reducing ECM diversity. LÄS MER
25. Effects of clear-cut logging on five old-growth forest bryophyte species. : How does the most common forestry method in Sweden impact vulnerable forest specialists?
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Clear-cut logging is the most widely practised forestry method in Sweden. This often conflicts with nature conservation and leads to issues where economic interests are pitted against ecological values. LÄS MER
