Tree and Tundra Cover Anomalies in the Subarctic Forest-Tundra of Northwestern Canada
Factors that may account for subarctic vegetation patterns that are not reconcilable with synoptic climate were sought by reference to data on local climate, soils, parent materials, vegetation, and topography. Where the forest-tundra lies climatically northward, the vegetation transition zone is relatively narrow, and the soils are nutrient-rich, fine-textured loamy Cryosols derived from sedim...
متن کاملSorption of dissolved organic matter by mineral soils of the Siberian forest tundra
Because of low net production in arctic and subarctic surface water, dissolved organic matter (DOM) discharged from terrestrial settings plays an important role for carbon and nitrogen dynamics in arctic aquatic systems. Sorption, typically controlling the export of DOM from soil, may be influenced by the permafrost regime. To confirm the potential sorptive control on the release of DOM from pe...

ACKNOWLEDGEMENTS: This thesis is a product under the International Polar Year (IPY) core project PPS Arctic (http://ppsarctic.nina.no) which was financially supported by the Research Council of Norway via the IPY grant 176065/S30 to A. Hofgaard. I would like to thank my supervisors Lars Söderström (NTNU) and Annika Hofgaard (NINA) for their time and effort in helping me build and structure this...
متن کاملBird Communities of the Arctic Shrub Tundra of Yamal: Habitat Specialists and Generalists
BACKGROUND The ratio of habitat generalists to specialists in birds has been suggested as a good indicator of ecosystem changes due to e.g. climate change and other anthropogenic perturbations. Most studies focusing on this functional component of biodiversity originate, however, from temperate regions. The Eurasian Arctic tundra is currently experiencing an unprecedented combination of climate...
متن کاملStraightforward inversion of vertical electrical sounding data
A straightforward inversion scheme (SIS) has been developed to interpret vertical electrical sounding data. This scheme does not require quasi-linearization of the inverse resistivity problem and thereby dispenses with the iterative process and the necessity of guessing the number of layers and their resistivities and thicknesses. The entire solution domain is divided into uniform thickness lay...
