Remote Sensing of Alpine Peatlands: Challenges of Mapping Thousands of Sparse Small Sites Scattered Across Extensive Mountainous Territories

Earth and Space Science
Alpine peatlands are one of the carbon reservoirs, provide vital ecosystem services, and support endangered biodiversity. However, they are globally understudied, including those in the Italian Alps, which host thousands of small sites averaging under 1 ...

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.

Canada's Forests Are Shifting From a Recovery-Driven Carbon Sink to a Disturbance-Driven Carbon Source. [PDF]

Glob Chang Biol
Canada's terrestrial ecosystems have historically functioned as a net carbon sink but are increasingly impacted by wildfire and timber harvest. Using wall‐to‐wall, physically coherent estimates of all major carbon pools and fluxes from the Canadian Land Surface Scheme Including Biogeochemical Cycles land surface model, we show that rising wildfire ...

Methane Emissions Offset Net Carbon Dioxide Uptake From an Alpine Peatland on the Eastern Qinghai‐Tibetan Plateau [PDF]

Journal of Geophysical Research: Atmospheres, 2021
Peatlands store large amounts of carbon (C) and actively exchange greenhouse gases (GHGs) with the atmosphere, thus significantly affecting global C cycle and climate.

Belowground cross-trophic networks impact CH4 and CO2 emissions in degraded alpine peatlands

Geoderma
Belowground organisms forming complex cross-trophic ecological networks are essential for maintaining peatland carbon stability and energy flow. However, how peatland degradation affects the biodiversity and cross-trophic ecological networks of soil ...

Peat swamp biodiversity in the Qizimei Mountain National Nature Reserve, China [PDF]

Mires and Peat, 2021
The Qizimei Mountain National Nature Reserve (QMNNR) is located in a hotspot for endemic species in China’s subtropical zone and contains large patches of sub-alpine peat swamp. To compile a species inventory and illustrate the threats to biodiversity in
