16. Myrar på Storön vid Norrbottenskusten
Sammanfattning : ELVELAND, J. 1976. Coastal mires on the Storön peninsula, Norrbotten, N Sweden. Wahlenbergia 3. LÄS MER
17. A song of ice and mud : Interactions of microbes with roots, fauna and carbon in warming permafrost-affected soils
Sammanfattning : Permafrost-affected soils store a large quantity of soil organic matter (SOM) – ca. half of worldwide soil carbon – and currently undergo rapid and severe warming due to climate change. LÄS MER
18. Holocene climate change in high latitudes recorded by stable isotopes in peat
Sammanfattning : A key to the understanding of natural and human induced climate variations is to reconstruct past changes from different environments. No outstanding method for general use has been pinpointed, instead, a need of multi-proxy studies is often stressed and the reconstructions are under constant improvement by new techniques. LÄS MER
19. Palsa Growth and Decay in Northern Sweden : Climatic and Environmental Controls
Sammanfattning : This thesis outlines the development and decay of palsas in northern Sweden in relation to climatic and environmental factors. Palsas were investigated on morphology, vegetation, peat porosity, ground temperature and local climate in four bogs situated on a north-south gradient in northern Sweden. LÄS MER
20. Boreal mire carbon exchange : sensitivity to climate change and anthropogenic nitrogen and sulfur deposition
Sammanfattning : Boreal peatlands are important long-term sinks of atmospheric carbon and in the same time the largest natural source of methane to the atmosphere. A changing climate as well as deposition of anthropogenically derived pollutants, such as nitrogen and sulfur, has the potential to affect the processes that control the carbon exchange in peatlands.
