Journal ArticleDOI
The whole-soil carbon flux in response to warming.
TL;DR: In a deep warming experiment in mineral soil, it was found that CO2 production from all soil depths increased with 4°C warming; annual soil respiration increased by 34 to 37%.
Book ChapterDOI
Storage and Turnover of Organic Matter in Soil
TL;DR: In this article, the storage and turnover of natural organic matter in soil (SOM), in the context of the global carbon cycle, has been studied, focusing on the central role that it plays in ecosystem fertility and soil properties.
Journal ArticleDOI
Warming and provenance limit tree recruitment across and beyond the elevation range of subalpine forest

TL;DR: Lower recruitment at all elevations with warming, combined with lower quality, high-provenance seed being most available for colonizing the alpine, portends range contraction for Engelmann spruce.
Journal ArticleDOI
Root litter decomposition slows with soil depth

TL;DR: In this article, the authors examined in situ decomposition processes in deep soils using 13C-labeled fine roots to 15, 55, and 95 cm depths of a well characterized coniferous forest Alfisol and monitored the amount of root-derived organic carbon remaining over 6, 12, and 30 months.
Journal ArticleDOI
Warming and the dependence of limber pine (Pinus flexilis) establishment on summer soil moisture within and above its current elevation range.
TL;DR: It is concluded that seasonal moisture stress and high soil surface temperature imposed a strong limitation to limber pine seedling establishment across a broad elevation gradient, including at treeline, and that these limitations are likely to be enhanced by further climate warming.
