Shallow soil moisture – ground thaw interactions and controls – Part 2: Influences of water and energy fluxes [PDF]

, 2010
The companion paper (Guan et al., 2010) demonstrated variable interactions and correlations between shallow soil moisture and ground thaw in soil filled areas along a wetness spectrum in a subarctic Canadian Precambrian Shield landscape.

The carbon balance of an alpine peatland in Northern Italy

, 2015
It is well known that peatlands store a vast amount of carbon in their soil and that with the ever-changing climate the stability of these carbon pools is under threat. But peatlands in high altitude regions are studied far less than peatlands in high latitude regions.

Animal board invited review: A biocultural perspective of animal farming systems in Europe

Animal
Europe’s landscapes have evolved through the intricate interplay of natural processes and human activities, one of which is animal farming; thus, historically creating biocultural landscapes rich in biological and cultural diversity.

Microbial diversity in hummock and hollow soils of three wetlands on the Qinghai-Tibetan plateau revealed by 16S rRNA pyrosequencing

, 2014
The wetlands of the Qinghai-Tibetan Plateau are believed to play an important role in global nutrient cycling, but the composition and diversity of microorganisms in this ecosystem are poorly characterized.

Alpine peatland degradation enhances soil nitrogen losses and alters plant nitrogen uptake strategies: evidence from nitrogen isotopes

Chemical and Biological Technologies in Agriculture
Background Nitrogen plays a critical role in sustaining ecosystem functions in peatlands; however, the degradation of approximately 12% of global peatlands substantially alters nitrogen cycling.

Mapping snow depth in open alpine terrain from stereo satellite imagery [PDF]

, 2016
International audienceTo date, there is no definitive approach to map snow depth in mountainous areas from spaceborne sensors. Here, we examine the potential of very-high-resolution (VHR) optical stereo satellites to this purpose.

Determining Spatially Variable Peat Depths of an Alpine Peatland in the Qinghai‐Tibet Plateau

Journal of Geophysical Research: Biogeosciences
AbstractUnderstanding peat depths is crucial for assessing carbon dynamics within peatlands. However, accurately estimating peat depths across large areas remains challenging. In this study, we developed a novel approach integrating a machine‐learning based regression modeling with an optimized field sampling strategy to predict spatially variable peat

Mechanisms Behind the Soil Organic Carbon Response to Temperature Elevations

Agriculture
Soil organic carbon (SOC) represents the most dynamic component of the soil carbon pool and is pivotal in the global carbon cycle. Global temperature rise and increasing drought severity are now indisputable realities, making soil organic carbon cycling ...

Alpine peatlands: spatially and temporally complex ecosystems with year-round methane cycling activity

Abstract Peatlands are well-known emitters of methane. European alpine peatlands share certain characteristics with boreal peatlands, despite being located at temperate latitudes, such as a strong seasonality with snowfall in winter and a short summer and growing season.
