MAESTRO Simulations of the Response of Loblolly Pine to Elevated Temperatures and Carbon Dioxide
An important tool in assessing the sensitivity of forests to global change is the simulation model of tree physiology. This tool must be used in conjunction with laboratory and field experiments. Population, ecosystem, and landscape-level models and analyses are also necessary to fully evaluate potential sensitivities to climate change. Physiological simulation models provide a unique method of exploring the complex nonlinear response surface of photosynthesis, respiration, transpiration, carbon allocation, and growth in trees. In principle this information could be obtained from controlled factorial experiments, however, a purely experimental approach would be extremely costly and time-consuming to implement for all of the species and regions of interest.
