The Prediction and Physiological Significance of Tree Heightand physical principles. The maximum height of trees is species-dependent. Within a species, increased availability of resources such as nutrients, water, and irradiance leads to increased height, but why is it that species do not grow higher than they do, even in the most favorable sites? Is there

Uncertainties in the Terrestrial Carbon Cycle projecting future changes in atmospheric CO. concentration. During this time, a natural starting point was to check the balance sheet that accounts for all carbon as it exchanged between the major global carbon reservoirs. While it is possible to achieve a balance for a single instant in time (for

Monitoring Vegetation Change Using Satellite Datae at the cellular level, the morphological/macroscopic level, or the community level. Figure 8.1 presents examples of some typical vegetation responses to stress. All of the examples of change at different levels given in Figure 8.1 have diagnostic spectral characteristics which can be detected by u

Global Geographic Information Systems and Databases for Vegetation Change Studies is: how is the current distribution of vegetation influenced by climatic factors and human disturbance, and how will it be influenced in the future? Finding the answer will depend largely on the development of models which consider the dynamic interplay between climatic factors, biogeochemistry, an

Modeling Large-Scale Vegetation Dynamicsnd modeling approaches that will be useful in analyzing responses of vegetation to large-scale environmental changes. We emphasize changing climate, but the concepts and approaches are pertinent to other global changes as well. First, we summarize the natural processes that dictate vegetation dynami

Rapid Simulations of Vegetation Stand Dynamics with Mixed Life-Forms mechanistic vegetation model suitable for exploring processes of global vegetation change in a changing environment over time-scales of decades to centuries, taking into account the processes of plant growth, regeneration, mortality, disturbance regimes, and dispersal that mediate the response to e

Plant Functional Typesin particular biomes, the factors governing structure and dynamics may vary considerably. For example, species composition and age structure in plant communities are largely controlled by asymmetric competition for an above-ground resource (light) and symmetric competition for below-ground resources
