Computer simulations and experiments were used to determine
the basis for skewness and inequality in size structures
(frequency distributions of Individual plant sizes) prior to
self-thinning mortality. In simulated stands, density-dependent
neighborhood heterogeneity caused variability in the growth rate
of individuals with the same size, and such variability caused
skewness...
An experimental protocol to determine the effects of temperature and light on the dissipation of xenobiotic substances in pesticide deposits is presented. A factorial design laboratory experiment is used to develop isothermal models of the dissipation of compounds over time in authentic pesticide deposits on excised leaves arid glass microscope...
