Analysing Amazonian forest productivity using a new individual and trait-based model (TFS v.1)
Amazonian forest productivity new individual trait-based model
2014/12/19
Repeated long-term censuses have revealed large-scale spatial patterns in Amazon basin forest structure and dynamism, with some forests in the west of the basin having up to a twice as high rate of ab...

In recent years we are observing devastating cyclones like Nargis, Gonu, Sidr, Liala, Phet etc in the North Indian Ocean associated with heavy rains, thunderstorm, high tide and intense winds that cau...
Spring molybdenum enrichment in scallop shells: a potential tracer of diatom productivity in temperate coastal environments (Brittany, NW France)
Spring molybdenum enrichment scallop shells diatom productivity temperate coastal environments
2010/1/21
Skeletal molybdenum/calcium ([Mo]/[Ca])shell ratios were examined in shells of the Great Scallop Pecten maximus collected in temperate coastal environments of Western Europe (42 to 49° N). These ratio...
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...
Influence of landscape heterogeneity on spatial patterns of wood productivity,wood specific density and above ground biomass in Amazonia
landscape heterogeneity spatial patterns wood productivity wood specific density
2010/1/21
Long-term studies using the RAINFOR network of forest plots have generated significant insights into the spatial and temporal dynamics of forest carbon cycling in Amazonia. In this work, we map and ex...
Biodiversity for multifunctional grasslands:equal productivity in high-diversity low-input and low-diversity high-input systems
Biodiversity multifunctional grasslands equal productivity high-diversity low-input

Modern grassland management seeks to provide many ecosystem services and experimental studies in resource-poor grasslands have shown a positive relationship between plant species richness and a variet...
Modelling basin-wide variations in Amazon forest productivity – Part 1:Model calibration,evaluation and upscaling functions for canopy photosynthesis
basin-wide variations Amazon forest productivity Model calibration evaluation
2010/1/20
Given the importance of Amazon rainforest in the global carbon and hydrological cycles, there is a need to parameterize and validate ecosystem gas exchange and vegetation models for this region in ord...
The interannual variability of Africa's ecosystem productivity:a multi-model analysis
interannual variability Africa's ecosystem productivity multi-model analysis
2010/1/19
We are comparing spatially explicit process-model based estimates of the terrestrial carbon balance and its components over Africa and confront them with remote sensing based proxies of vegetation pro...
Effects of storms on primary productivity and air-sea CO2 exchange in the subarctic western North Pacific:a modeling study
storms primary productivity air-sea CO2 exchange North Pacific
2010/1/18
Biogeochemical responses of the open ocean to storms and their feedback to climate are still poorly understood. Using a marine ecosystem model, we examined biogeochemical responses to the storms in th...
