The relationship between stem-form, stand-closure and site -conditions : the influence of environmental conditions on tree allometry and forest structure in west-central Alberta
… timber. Tree allometry, as represented by stem-fo~, is the result of the vertical force of gravity and the horizontal force of wind. The effect of wind force is demonstrated in the relationship between stem-form, standclosure and site-conditions. An increase in wind force on the individual …

Modeling Stem Taper of Southern Appalachian Red Spruce
… red spruce stands through regionally fitted stem taper equations and to examine differences in stem form between the northern and southern populations of red spruce. In Chapter 1, five stem taper equations were evaluated for their ability to predict upper stem diameters and total volume in …

Modeling thinning effects on ring width distribution and wood specific gravity of loblolly pine (Pinus taeda L.)
… ring width distribution 3) thinning effects on stem form, and 4) prediction models for these quantities. The study showed that thinning does not significantly affect ring specific gravity, whereas its effects on ring width distribution and stem form were significant. Thinning increases ring …

Ossetian: Revisiting inflectional morphology
… In the chapter on verbal morphology, the forms previously described as infinitives are discussed and one of them is reanalyzed as a derived noun or adjective; the majority of verbs are regarded as having one stem form; tense is analyzed as a suffix that attaches to the stem; mood, person, …

Methods for modeling whole stem diameter growth and taper
Stem profile models which allow for both taper and form changes (Gray 1956) were constructed and evaluated. Gray defined form to be the basic shape of the tree, e.g. cone or parabolid, and taper to be the rate of narrowing in diameter given a tree form. Ormerod's stem profile model was selected as …

Developing a Taper Model for Pinus elliottii x caribaea in South Africa
… taper models is due to the variability in stem form and taper between tree species and even within species. Therefore, although a lot of studies have been done with regards to taper functions, it remains a field of active study, as more species, hybrids and new areas are explored and …
