Laboratory incubation soil nutrient availability and microbial biomass, Agashashok River, Alaska, 2019
The position of the Arctic treeline is an important regulator of surface energy budgets, carbon cycling and subsistence resources in high latitude environments. It has long been thought that temperature exerts a direct control on growth of treeline trees and the position of the treeline. However, ou...

The position of the Arctic treeline is an important regulator of surface energy budgets, carbon cycling and subsistence resources in high latitude environments. It has long been thought that temperature exerts a direct control on growth of treeline trees and the position of the treeline. However, our recent work on white spruce in the Arctic suggests that indirect effects of temperature on tree access to soil nutrients may be of equal or greater importance. Our recent results provide correlative evidence of the importance of winter snow depth as a driver of tree growth. The aim of this project was to experimentally isolate the importance of snow depth and soil nutrient availability and examine the consequences for microbial processes, tree growth and treeline advance. This dataset contains measurements of soil nutrient availability and microbial biomass made at the beginning and end of a 3-month laboratory incubation in which soils were held at a range of temperatures (-10, -6, -2, 2 and 6 degrees Celsius (deg C)), crossed with a range of labile carbon (C) additions (0, 0.2, 0.4, and 2 milligrams of carbon per gram of dry soil (mg C per g dry soil)). |
