Northern hardwoods have undergone a marked change in their dynamics, with American beech (Fagus grandifolia Ehrh.) increasing in abundance relative to sugar maple (Acer saccharum Marsh.). This study aims to better understand this sudden shift in recruitment dynamics. We performed an extensive analysis of the age structure, radial growth pattern, and release history on >700 saplings from 34 matu...

We present a Maple package called SyNRAC. This package is aimed at becoming a comprehensive toolbox for solving real algebraic constraints derived from various engineering problems. The current version of SyNRAC provides quantifier elimination for up to the quadratic case and basic simplifiers of formulas, as well as an environment dealing with first-Order formulas over the reals on Maple.

Quantitative differences in leaf abscisic acid (ABAL) among four cultivars of red maple (Acer rubrum L.) and one freeman maple (Acer ×freemanii E. Murray) cultivar were investigated. This study tested the hypothesis that ABAL concentration can be used to compare the effects of water stress on the gas exchange response of fi ve different maple genotypes, including four red maple cultivars [‘Summ...
