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.

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.

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.

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.

Habitat-Based Predictions of Bridle Shiner (<i>Notropis bifrenatus</i>) in the Northeastern United States. [PDF]

Ecol Evol
We developed local and regional models for Maine and New Hampshire that may be used to focus bridle shiner (Notropis bifrenatus) surveys on areas with high predicted habitat suitability. This is significant because bridle shiners receive protection or concern status in thirteen states and two Canadian provinces: Limited data show that bridle shiners ...

Focus on the impact of climate change on wetland ecosystem and carbon dynamics [PDF]

, 2016
The renewed growth in atmospheric methane (CH4)since 2007 after a decade of stabilization has drawn much attention to its causes and future trends. Wetlands are the single largest source of atmospheric CH4.

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.

Impact of natural gullies on groundwater hydrology in the Zoige peatland, China

Journal of Hydrology: Regional Studies, 2019
Study region: The study area was in the upland peatland within the Zoige basin with elevations ranging between 3400 and 3800 m. It is located in the source area of Upper Yellow River that is developed on the Qinghai-Tibet Plateau, China.

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 ...
