Two factors that play a key role in climate change - increased climate warming and elevated ozone levels - appear to have detrimental effects on soybean plant roots, their relationship with symbiotic ...
Plant functional type classification for earth system models:results from the European Space Agency's Land Cover Climate Change Initiative
Plant functional type classification earth system models European Space Agency Land Cover Climate Change Initiative
2015/8/6
Global land cover is a key variable in the earth system with feedbacks on climate, biodiversity and natural resources. However, global land cover data sets presently fall short of user needs in provid...
IPR 1.0: an efficient method for calculating solar radiation absorbed by individual plants in sparse heterogeneous woody plant communities
an efficient method calculating solar radiation absorbed by individual plants sparse heterogeneous woody plant communities
2014/12/19
Climate change may alter the spatial distribution, composition, structure and functions of plant communities. Transitional zones between biomes, or ecotones, are particularly sensitive to climate chan...
Development of a plume-in-grid model for industrial point and volume sources: application to power plant and refinery sources in the Paris region
Model and eulerian model subgrid scale model stack simulation nitrogen oxides organic compounds
2014/12/18
Plume-in-grid (PinG) models incorporating a host Eulerian model and a subgrid-scale model (usually a Gaussian plume or puff model) have been used for the simulations of stack emissions (e.g., fossil f...

The sensitivity of global carbon and water cycling
to climate variability is coupled directly to land cover and the
distribution of vegetation. To investigate biogeochemistryclimate interactions, ea...
Wet scavenging of SO2 emissions around India's largest lignite based power plant
Wet scavenging SO2 emissions India's largest lignite based power plant
2010/9/10
The Neyveli Lignite Corporation (NLC) is among the largest lignite based power plants in South East Asia. The four elevated stacks from this power plant emanate a substantial amount of sulphur dioxide...
Soil,plant,and transport influences on methane in a subalpine forest under high ultraviolet irradiance
Soil plant transport influences methane subalpine forest high ultraviolet irradiance
2010/1/20
Recent studies have demonstrated direct methane emission from plant foliage under aerobic conditions, particularly under high ultraviolet (UV) irradiance. We examined the potential importance of this ...
A new European plant-specific emission inventory of biogenic volatile organic compounds for use in atmospheric transport models
plant-specific emission inventory biogenic volatile organic compounds transport models
2010/1/20
We present a new European plant-specific emission inventory for isoprene, monoterpenes, sesquiterpenes and oxygenated VOC (OVOC), on a spatial resolution of 0.089×0.089 degrees, for implementation in ...
Towards spatial assessment of carbon sequestration in peatlands:spectroscopy based estimation of fractional cover of three plant functional types
spatial assessment carbon sequestration peatlands fractional cover
2010/1/19
Peatlands accumulated large carbon (C) stocks as peat in historical times. Currently however, many peatlands are on the verge of becoming sources with their C sequestration function becoming sensitive...
Temporal variability in bioassays of the stomatal ammonia compensation point in relation to plant and soil nitrogen parameters in intensively managed grassland
Temporal variability stomatal ammonia compensation point plant and soil nitrogen parameters
2010/1/19
The exchange of ammonia between crop canopies and the atmosphere depends on a range of plant parameters and climatic conditions. However, little is known about effects of management factors. We have h...
Contribution of different grass species to plant-atmosphere ammonia exchange in intensively managed grassland
Contribution grass species plant-atmosphere ammonia exchange grassland
2010/1/19
Species diversity in grasslands usually declines with increasing input of nitrogen from fertilizers or atmospheric deposition. Conversely, species diversity may also impact the build-up of soil and pl...
Plant physiological and environmental controls over the exchange of acetaldehyde between forest canopies and the atmosphere
physiological and environmental controls exchange forest canopies atmosphere
2010/1/18
We quantified fine scale sources and sinks of gas phase acetaldehyde in two forested ecosystems in the US. During the daytime, the upper canopy behaved as a net source while at lower heights, reduced ...
No detectable aerobic methane efflux from plant material,nor from adsorption/desorption processes
aerobic methane efflux plant material adsorption desorption processes
2010/1/18
In early 2006, Keppler et al. (Nature, 439:187–191) reported a novel finding that plant leaves, and even simple organic materials, can release methane under aerobic conditions. We investigated here wh...
