Sensitivity analysis and calibration of a soil carbon model (SoilGen2) in two contrasting loess forest soils
Sensitivity analysis calibration soil carbon model two contrasting loess forest soils
2014/12/17
To accurately estimate past terrestrial carbon pools is the key to understanding the global carbon cycle and its relationship with the climate system. SoilGen2 is a useful tool to obtain aspects of so...
Fine root dynamics for forests on contrasting soils in the Colombian Amazon
Fine root dynamics forests contrasting soils the Colombian Amazon
2010/1/21
It has been hypothesized that as soil fertility increases, the amount of carbon allocated to below-ground production (fine roots) should decrease. To evaluate this hypothesis, we measured the standing...
Above- and below-ground net primary productivity across ten Amazonian forests on contrasting soils
Above- and below-ground net primary productivity ten Amazonian forests contrasting soils
2010/1/21
The net primary productivity (NPP) of tropical forests is one of the most important and least quantified components of the global carbon cycle. Most relevant studies have focused particularly on the q...
Coupling of surface pCO2 and dissolved oxygen in the northern South China Sea:impacts of contrasting coastal processes
surface pCO2 dissolved oxygen South China Sea coastal processes
2010/1/21
We examined the relationship between CO2 partial pressure (pCO2) and dissolved oxygen (DO) based on a cruise conducted in July 2004 to the northern South China Sea (111°–118° E 18°–23° N), spanning fr...
Effects of N and P fertilization on the greenhouse gas exchange in two northern peatlands with contrasting N deposition rates
N and P fertilization greenhouse gas exchange northern peatlands N deposition rates
2010/1/21
Peatlands are important ecosystems in the context of biospheric feedback to climate change, due to the large storage of organic C in peatland soils. Nitrogen deposition and increased nutrient availabi...
Contrasting carbon dioxide fluxes between a drying shrub wetland in Northern Wisconsin,USA,and nearby forests
carbon dioxide fluxes shrub wetland Northern Wisconsin
2010/1/20
Wetland biogeochemistry is strongly influenced by water and temperature dynamics, and these interactions are currently poorly represented in ecosystem and climate models. A decline in water table of a...
Nitrate retention and removal in Mediterranean streams bordered by contrasting land uses:a 15N tracer study
Nitrate retention removal Mediterranean streams contrasting land uses 15N tracer
2010/1/19
We used 15N-labelled nitrate (NO3−) additions to investigate pathways of nitrogen (N) cycling at the whole-reach scale in three stream reaches with adjacent forested, urban and agricultural land...
Carbon and oxygen isotope analysis of leaf biomass reveals contrasting photosynthetic responses to elevated CO2 near geologic vents in Yellowstone National Park
isotope analysis leaf biomass reveals photosynthetic responses CO2 geologic vents
2010/1/19
In this study we explore the use of natural CO2 emissions in Yellowstone National Park (YNP) in Wyoming, USA to study responses of natural vegetation to elevated CO2 levels. Radiocarbon (14C) analysis...
Distribution of lipid biomarkers and carbon isotope fractionation in contrasting trophic environments of the South East Pacific
lipid biomarkers carbon isotope fractionation trophic environments Pacific
2010/1/15
The distribution of lipid biomarkers and their stable carbon isotope composition was investigated on suspended particles from different contrasting trophic environments at six sites in the South East ...
Net ecosystem carbon exchange in three contrasting Mediterranean ecosystems – the effect of drought
Net ecosystem carbon exchange Mediterranean ecosystems effect of drought
2010/1/14
Droughts reduce gross primary production (GPP) and ecosystem respiration (Reco), contributing to most of the inter-annual variability in terrestrial carbon sequestration. In seasonally dry climates (M...
