Effects of extreme drought on soil microbial functional genes involved in carbon and nitrogen cycling in alpine peatland

Frontiers in Ecology and Evolution, 2023
Diverse microorganisms drive biogeochemical cycles and consequently influence ecosystem-level processes in alpine peatlands, which are vulnerable to extreme drought induced by climate change.

Characterizing Alpine peatlands from drones: a case study

, 2022
Alpine peatlands occur in alpine, sub-alpine and mountain regions of the world and can be frequently found on the Alps as well as on the Andes, on the Tibetan Plateau, on the Australian Alps and in other regions of the world. Italian Alps host a large number of relatively small bogs and fens that can be found on gently sloping surfaces or in small ...

The effect of drainage on CO2, CH4 and N2O emissions in the Zoige peatland: a 40-month in situ study [PDF]

Mires and Peat, 2018
The Zoige peatland on the Qinghai-Tibet Plateau, the largest alpine peatland in the world, is currently experiencing unprecedented water stress due to climate change and human activities.

Methane emissions offset net carbon dioxide uptake from an alpine peatland on the Eastern Qinghai-Tibetan Plateau [PDF]

Journal of Geophysical Research: Atmospheres, 2021
AbstractPeatlands store large amounts of carbon (C) and actively exchange greenhouse gases (GHGs) with the atmosphere, thus significantly affecting global C cycle and climate. Large uncertainty exists in C and GHG estimates of the alpine peatlands on Qinghai‐Tibetan Plateau (QTP), as direct measurements of CO2 and CH4 fluxes are scarce in this region ...

Nongrowing Season CO₂ Emissions Determine the Distinct Carbon Budgets of Two Alpine Wetlands on the Northeastern Qinghai—Tibet Plateau

Atmosphere, 2021
Alpine wetlands sequester large amounts of soil carbon, so it is vital to gain a full understanding of their land-atmospheric CO2 exchanges and how they contribute to regional carbon neutrality; such an understanding is currently lacking for the Qinghai ...

Snow depth time series retrieval by time-lapse photography: Finnish and Italian case studies [PDF]

The Cryosphere, 2021
The capability of time-lapse photography to retrieve snow depth time series was tested. Historically, snow depth has been measured manually by rulers, with a temporal resolution of once per day, and it is a time-consuming activity.

Decline of the boreal willow grouse (Lagopus lagopus) has been accelerated by more frequent snow-free springs [PDF]

, 2020
Climate change has influenced a range of species across the globe. Yet, to state a noted decline in the abundance of a given species as a consequence of a specific environmental change, for instance, spatially explicit long-term data are a prerequisite.

Leaf area index and aboveground biomass estimation of an alpine peatland with a UAV multi-sensor approach

GIScience & Remote Sensing, 2023
Aboveground biomass (AGB) can serve as an indicator when estimating various biogeochemical processes in peatlands, an ecosystem which provides countless ecosystem services and plays a key role in climate regulation.

Bomb-¹⁴C analysis of ecosystem respiration reveals that peatland vegetation facilitates release of old carbon [PDF]

, 2009
The largest terrestrial-to-atmosphere carbon flux is respired CO₂. However, the partitioning of soil and plant sources, understanding of contributory mechanisms, and their response to climate change are uncertain.

Field Simulation of Global Change: Transplanting Northern Bog Mesocosms Southward [PDF]

, 2010
A large proportion of northern peatlands consists of Sphagnum-dominated ombrotrophic bogs. In these bogs, peat mosses (Sphagnum) and vascular plants occur in an apparent stable equilibrium, thereby sustaining the carbon sink function of the bog ecosystem.
