Optimization of a prognostic biosphere model for terrestrial biomass and atmospheric CO2 variability
prognostic biosphere model terrestrial biomass atmospheric CO2 variability
2014/12/19
This study investigates the capacity of a prognostic biosphere model to simulate global variability in atmospheric CO2 concentrations and vegetation carbon dynamics under current environmental conditi...
Effects of vegetation structure on biomass accumulation in a Balanced Optimality Structure Vegetation Model (BOSVM v1.0)
Balanced Optimality Structure Vegetation Model vegetation structure
2014/12/18
A myriad of interactions exist between vegetation
and local climate for arid and semi-arid regions. Vegetation
function, structure and individual behavior have large impacts on carbon–water–energy b...
A model for global biomass burning in preindustrial time: LPJ-LMfire (v1.0)
global biomass pre industrial time LPJ-LMfire
2014/12/12
Fire is the primary disturbance factor in many terrestrial ecosystems. Wildfire alters vegetation structure and composition, affects carbon storage and biogeochemical cycling, and results in the relea...
Validation of modelled forest biomass in Germany using BETHY/DLR
BETHY/DLR modelled forest biomass
2014/12/9
We present a new approach to the validation
of modelled forest Net Primary Productivity (NPP), using
empirical data on the mean annual increment, or MAI, in
above-ground forest stock. T
Sahara dust, ocean spray, volcanoes, biomass burning: pathways of nutrients into Andean rainforests
Sahara dust ocean spray volcanoes Andean rainforests
2010/1/28
Regular rain and fogwater sampling in the Podocarpus National Park, on the humid eastern slopes of the Ecuadorian Andes, along an altitude profile between 1960 and 3180 m, has been carried out since 2...
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...
Applying biomass and stem fluxes to quantify temporal and spatial fluctuations of an old-growth forest in disturbance
biomass stem fluxes temporal and spatial fluctuations old-growth forest
2010/1/21
A subtropical old-growth forest was studied over a twelve-year period to investigate temporal and spatial fluctuations of biomass and stem fluxes under disturbances. Vegetations were categorized into ...
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...
Effect of UV radiation and temperature on the emission of methane from plant biomass and structural components
UV radiation emission methane plant biomass structural components
2010/1/15
The recently reported finding that plant matter and living plants produce significant amounts of the important greenhouse gas methane under aerobic conditions has led to an intense scientific and publ...
Biomass production in experimental grasslands of different species richness during three years of climate warming
Biomass production experimental grasslands species richness climate warming
2010/1/15
Here we report on the single and combined impacts of climate warming and species richness on the biomass production in experimental grassland communities. Projections of a future warmer climate have s...
