1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

2. Effects on natural seed regenerated Silver birch (Betula pendula Roth) and Downey birch (Betula pubescens Ehrh) by mechanical soil scarification and environmental factors : påverkan på naturligt fröföryngrad Glasbjörk (Betula pubescens Ehrh) och Hängbjörk (Betula pendula Roth) av mekanisk markberedning och omgivande faktorer
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : The awareness of forest biodiversity as well as the demand for a higher proportion of deciduous tree species in Swedish forests increases. As such, focus is shifting towards the management of naturally seed regenerated Silver birch (Betula pendula Roth) and Downey birch (Betula pubescens Ehrh). LÄS MER
3. Above- and belowground carbon stocks and effects of enrichment planting in a tropical secondary lowland dipterocarp rainforest
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : The intact tropical rainforests are rapidly being degraded and subsequently converted to other land uses, with associated greenhouse gas emissions and loss of biodiversity. It is imperative that the effects of such conversions and large-scale restoration efforts on forest structure and ecosystem services are understood to effectively be able to counteract the negative consequences of deforestation and forest degradation.

4. Ecological and Edaphic Correlations of Soil Invertebrate Community Structure in Dry Upland Forests of Eastern Africa
Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskapSammanfattning : Natural forests are characterised by great vegetation diversity and create habitats for a major part of Earth’s terrestrial organisms. Plantation forests, which are mainly composed of a few genera of fast-growing trees, constitute an increasing fraction of global forests, but they only partly compensate for loss of area, habitat and ecological functions in natural forests.

5. Ståndortsfaktorer och vegetation : En problematiserande litteraturstudie
Kandidat-uppsats, Stockholms universitet/Institutionen för naturgeografiSammanfattning : Ståndort är ett område där ett bestånd av en viss växt finns, ofta avses träd inom skogsproduktion. Förutsättningarna för detta, ståndortsfaktorer, återfinns i markens egenskaper (edafiska faktorer) och klimatet. LÄS MER
