Seasonal leaf dynamics for tropical evergreen forests in a process-based global ecosystem model
Tropical evergreen forest canopy seasonal phenology photosynthesis ecosystem models canopy leaf photosynthetic capacity carbon dioxide the forest
2014/12/10
The influence of seasonal phenology on canopy photosynthesis in tropical evergreen forests remains poorly understood, and its representation in global ecosystem models is highly simplified, typically ...
Influences of Leaf Area Index estimations on water balance modeling in a Mediterranean semi-arid basin

2009/12/8
In the present work, the role played by vegetation parameters, necessary to the hydrological distributed modeling, is investigated focusing on the correct use of remote sensing products for the evalua...
Spatial trends in leaf size of Amazonian rainforest trees
Spatial trends leaf size Amazonian rainforest trees
2010/1/20
Leaf size influences many aspects of tree function such as rates of transpiration and photosynthesis and, consequently, often varies in a predictable way in response to environmental gradients. The re...

2010/1/20
Leaves in tropical forests come in an enormous variety of sizes and shapes, each of which can be ultimately viewed as an adaptation to the complex problem of optimising the capture of light for photos...
Modelling the dynamic chemical interactions of atmospheric ammonia with leaf surface wetness in a managed grassland canopy
dynamic chemical interactions atmospheric ammonia leaf surface wetness grassland canopy
2010/1/19
Ammonia exchange fluxes between grassland and the atmosphere were modelled on the basis of stomatal compensation points and leaf surface chemistry, and compared with measured fluxes during the GRAMINA...
Carbon and oxygen isotope analysis of leaf biomass reveals contrasting photosynthetic responses to elevated CO2 near geologic vents in Yellowstone National Park
