Vegetation NDVI Linked to Temperature and Precipitation in the Upper Catchments of Yellow River [PDF]

open access: yes, 2012
Vegetation in the upper catchment of Yellow River is critical for the ecological stability of the whole watershed. The dominant vegetation cover types in this region are grassland and forest, which can strongly influence the eco-environmental status of ...

Biomass-modulated fire dynamics during the last glacial-interglacial transition at the central pyrenees (Spain) [PDF]

open access: yes, 2014
Understanding long-term fire ecology is essential for current day interpretation of ecosystem fire responses. However palaeoecology of fire is still poorly understood, especially at high-altitude mountain environments, despite the fact that these are ...

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

open access: yes, 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.

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

open access: yesJournal 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.

Controls on ecosystem respiration of carbon dioxide across a boreal wetland gradient in Interior Alaska [PDF]

open access: yes, 2012
Thesis (M.S.) University of Alaska Fairbanks, 2012Permafrost and organic soil layers are common to most wetlands in interior Alaska, where wetlands have functioned as important long-term soil carbon sinks.

Effect of permafrost thaw on CO2 and CH4 exchange in a western Alaska peatland chronosequence [PDF]

open access: yes, 2014
Permafrost soils store over half of global soil carbon (C), and northern frozen peatlands store about 10% of global permafrost C. With thaw, inundation of high latitude lowland peatlands typically increases the surface-atmosphere flux of methane (CH4), a

Permafrost Distribution in Peatlands of West-Central Canada During the Holocene Warm Period 6000 Years BP [PDF]

open access: yes, 1995
The extent and distribution of permafrost in peatlands 6000 years ago was investigated in the present discontinuous and continuous permafrost zones of west-central Canada.

Spatio-Temporal Characteristics and Driving Mechanism of Alpine Peatland InSAR Surface Deformation—A Case Study of Maduo County, China

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Surface deformation of alpine peatland in China has an important effect on runoff and is of great significance for wetland ecosystem protection. However, spatio-temporal characteristics of alpine peatland surface deformation in China lack systematic ...
