Carbon fluxes of an alpine peatland in Northern Italy [PDF]

Agricultural and Forest Meteorology, 2016
It is widely known that peatlands are a significant carbon (C) stock. Most peatlands are located in boreal and subarctic regions of the northern hemisphere but some occur also at high altitude and, contrary to the first; their contribution in terms of carbon sequestration is far less studied.

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 ...

Interactions and Covariation of Ecological Drivers Control CO2 Fluxes in an Alpine Peatland

Wetlands, 2023
AbstractPeatland ecosystems are a highly effective long-term carbon sink. However, the CO2 fluxes could be substantially altered by climate changes and the fate of carbon stored in these ecosystems is still uncertain. Currently, most studies concerning the carbon fluxes in peatlands were performed at high latitude sites, where these ecosystems are more

Plant and Soil Enzyme Activities Regulate CO2 Efflux in Alpine Peatlands After 5 Years of Simulated Extreme Drought [PDF]

Frontiers in Plant Science, 2021
Increasing attention has been given to the impact of extreme drought stress on ecosystem ecological processes. Ecosystem respiration (Re) and soil respiration (Rs) play a significant role in the regulation of the carbon (C) balance because they are two ...

Rewetting Decreases Carbon Emissions from the Zoige Alpine Peatland on the Tibetan Plateau [PDF]

Sustainability, 2017
Peatlands play an important role in the global carbon cycle and potentially have a significant impact on regional climate change. Restoring and rewetting the degraded peatlands is an urgent task. However, effects of rewetting on the carbon emissions of peatlands remain poorly understood.

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 ...

Probabilistic Petrophysical Reconstruction of Danta's Alpine Peatland via Electromagnetic Induction Data

Earth and Space Science
Peatlands are fundamental deposits of organic carbon. Thus, their protection is of crucial importance to avoid emissions from their degradation. Peat is a mixture of organic soil that originates from the accumulation of wetland plants under continuous or

Reduced Carbon Dioxide Sink and Methane Source under Extreme Drought Condition in an Alpine Peatland [PDF]

Sustainability, 2018
Potential changes in both the intensity and frequency of extreme drought events are vital aspects of regional climate change that can alter the distribution and dynamics of water availability and subsequently affect carbon cycles at the ecosystem level.

Climate and human impacts inferred from a 1500-year multi-proxy record of an alpine peatland in the South-Eastern Alps

Ecological Indicators, 2022
In the last decades, climate and human activities significantly affected ecosystems, particularly in mountain areas. Whereas the Alps have been extensively studied for palaeoclimatic reconstructions, little information is available about ecological ...
