Chemical Characteristics of Flow Driven by Rainfall and Associated Impacts on Shallow Groundwater Quality in a Karst Watershed, Southwest China
Monitoring from 2016 to 2018 was used to investigate seasonal variation of chemical characteristics and define the water quality status within a subsurface river system in a karst region of Southwest China. Fo...

Open AccessBedrock geochemistry influences vegetation growth by regulating the regolith water holding capacity
Although low vegetation productivity has been observed in karst regions, whether and how bedrock geochemistry contributes to the low karstic vegetation productivity remain unclear. In this study, we address th...

Widespread drying of European peatlands in recent centuries
Climate warming and human impacts are thought to be causing peatlands to dry, potentially converting them from sinks to sources of carbon. However, it is unclear whether the hydrological status of peatlands ha...

Rock crevices determine woody and herbaceous plant cover in the karst critical zone
The study of the critical zones (CZs) of the Earth link the composition and function of aboveground vegetation with the characteristics of the rock layers, providing a new way to study how the unique rock and ...

Migration and leaching characteristics of base cation: indicating environmental effects on soil alkalinity in a karst area
In karst areas, rock dissolution often results in the development of underground networks, which act as subterranean pathways for rapid water and nutrient (and possibly soil) loss during precipitation events. ...

Open AccessMethane and carbon dioxide fluxes from open and blocked ditches in a blanket bog
There is growing interest in how the rewetting of drained peatlands can restart their carbon (C) sink function. However, there are few studies on the effect of ditch blocking on the within-ditch C balance. For...

Open AccessAn experimental study on the response of blanket bog vegetation and water tables to ditch blocking
We studied the effect of ditch blocking on vegetation composition and water-table depths in a blanket peatland. Measurements were made for a period of four years (water tables) and five years (vegetation) in t...

Open AccessEcosystem service delivery in Karst landscapes: anthropogenic perturbation and recovery
Covering extensive parts of China, Karst landscapes are exceptional because rapid and intensive land use change has caused severe ecosystem degradation within only the last 50 years. The twentieth century inte...

Open AccessThe importance of non-carbonate mineral weathering as a soil formation mechanism within a karst weathering profile in the SPECTRA Critical Zone Observatory, Guizhou Province, China
Soil degradation, including rocky desertification, of the karst regions in China is severe. Karst landscapes are especially sensitive to soil degradation as carbonate rocks are nutrient-poor and easily eroded....

A mesocosm study of the effect of restoration on methane (CH4) emissions from blanket peat
In a mesocosm study, we investigated the effect of different restoration methods on methane (CH4) emissions from, and the global warming potential (GWP) of, blanket peat. The controlled laboratory study involved ...

A mesocosm study of the role of the sedge Eriophorum angustifolium in the efflux of methane—including that due to episodic ebullition—from peatlands
Vascular plants may reduce episodic ebullition losses of methane (CH4) from peatlands. They transport CH4 to the atmosphere, which may lead to a reduction in pore-water [CH4], bubble formation and release. This e...

Does road salting induce or ameliorate DOC mobilisation from roadside soils to surface waters in the long term?
Soils down slope of roads have been affected over decades by road salting in the UK uplands. Salt additions to fresh soil facilitate dispersal of organic matter so there is a potential risk of release of DON a...

Nitrogen Cycle Disruption through the Application of De-icing Salts on Upland Highways
It is hypothesized that episodic introductions of road salt severely disrupt the soil nitrogen cycle at a range of spatial and temporal scales. A field-scale study has confirmed impacts on the nitrogen cycle i...
