Upscaling Tundra CO2 Exchange from Chamber to Eddy Covariance Tower

Paul C. Stoy* Extrapolating biosphere-atmosphere CO2 flux observations to larger scales in space, part of Mathew Williams† the so-called ‘‘upscaling’’ problem, is a central challenge for surface-atmosphere exchange Jonathan G. Evans‡ research. Upscaling CO2 flux in tundra is complicated by the pronounced spatial variability Ana Prieto-Blanco§ of vegetation cover. We demonstrate that a simple mo...

Carbon budget estimation of a subarctic catchment using a dynamic ecosystem model at high spatial resolution

A large amount of organic carbon is stored in highlatitude soils. A substantial proportion of this carbon stock is vulnerable and may decompose rapidly due to temperature increases that are already greater than the global average. It is therefore crucial to quantify and understand carbon exchange between the atmosphere and subarctic/arctic ecosystems. In this paper, we combine an Arctic-enabled...

15 22 Payette

The tundra-taiga interface, or forest-tundra (lesotundra in Russian, and toundra forestière in French), corresponds to the subarctic zone where the closed boreal forest gradually becomes less dense and progressively breaks down into tree islands towards the treeless, Arctic tundra (1). The interface does not form a sharp limit of tree growth in the landscape but is instead a north-south transit...

Bacterial community structure and soil properties of a subarctic tundra soil in Council, Alaska

The subarctic region is highly responsive and vulnerable to climate change. Understanding the structure of subarctic soil microbial communities is essential for predicting the response of the subarctic soil environment to climate change. To determine the composition of the bacterial community and its relationship with soil properties, we investigated the bacterial community structure and proper...

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...
