Abstract:: Uptake, in-plant transport, and local accumulation of organic chemicals by plants are influenced by plant characteristics, properties of the chemical and the soil, and by environmental conditions. Evaluations of plant contamination required by regulatory agencies cannot be made experimentally for the many thousands of xenobiotic chemicals in existence or being...

Abstract:: Equations for predicting the probability of a tree's dying in the next 5 years are presented for eight conifer and eight hardwood tree species from southwest Oregon. A logistic equation form was used to characterize the probability of mortality. The parameters of the equation were estimated using weighted, maximum likelihood...

Abstract:: CTSPAC is a mathematical model for coupled transport of water, solutes, and thermal energy in the soil-plant-atmosphere continuum. The mathematical structure consists of coupling a model for transport through soil (soil submodel) to one for xylem and phloem transport (plant submodel). The modeling approach is based on discrete space conceptualization...
