31. Land use effects on greenhouse gas emissions from boreal inland waters
Sammanfattning : Anthropogenic activities perturb the global carbon and nitrogen cycle with large implications for the earth’s climate. Land use activities deliver excess carbon and nitrogen to aquatic ecosystems. In the boreal biome, this is mainly due to forestry and atmospheric deposition. LÄS MER
32. Responses of boreal forest understory plant communities to climate and forestry
Sammanfattning : A warming climate is altering species distributions and community compositions. To understand and predict changes in species distributions to climate change, we often use species occurrences together with large-scale regional climate data. This can be problematic for several reasons. LÄS MER
33. Living on the edge : effectiveness of buffer strips in protecting biodiversity on boreal riparian forests
Sammanfattning : The objective of this thesis is to evaluate the ecological consequences of buffer strip retention on riparian and terrestrial biodiversity. Earlier studies on forest buffer strips have evaluated their effectiveness in relation to water quality and aquatic biota. However, forests along streams are species rich habitats for many organism groups. LÄS MER
34. Characterisation of boreal forests and urban areas using ERS InSAR Coherence
Sammanfattning : .... LÄS MER
35. Hydrological aspects of the carbon balance in a boreal catchment: A model study
Sammanfattning : AbstractThe cycling of carbon in its gaseous, solid and dissolved forms is of central importance to ecosystem science, particularly, when the natural carbon cycle has been perturbed by human activity. Mathematical models are commonly used to asses and predict global and regional patterns of terrestrial carbon exchange. LÄS MER
