Link Allelopathy in Trees
Trees have developed in ecological systems filled with many other organisms. The environment, shared by all, contains limited resources and less-than-ideal ...
Link Allelopathy in Trees and Forests: A Selected Bibliography
Allelopathy in trees and forests is an important health care issue. Allelopathy is the chemical modification of the site by an individual to enhance ...
Link Autumn Colors - How Leaves Change Color
The "Indian summer" days of autumn, when the days are clear and sunny and the nights cool and crisp, provide an almost irresistible lure to those who enjoy the ...
Link Control of Nitrogen Levels in Trees
From an energy standpoint, uptake and reduction of nitrates with incorporation into an organic framework is one of the most expensive tasks a tree performs. It ...
Link Control of Shoot-root Balance in Trees
This publication is a synthesis of the tree growth regulation and correlation literature. General processes and systems presented here represent educational ...
Link Critical Force for Buckling Tree Stems
Tree strength and stiffness can resist significant forces and not fail. A large proportion of this strength lies with the thickness (diameter) of the stem. ...
Link Crown Pruning Effects on Roots
Tree growth and development are dependent upon a few basic mechanisms. These mechanisms are responsible for the tree making holistic adjustments to a changing ...
Link Crown Shape Factors & Volumes
Many of the models for determining loads and forces in tree structural systems depend upon crown shape. Tree crown shapes are integral to a variety of models ...
Link Growth Increment Area Increase
The secondary growth of trees produces unique mechanical and biological solutions to life. From shoot tip to root tip, a new growth increment is deposited on ...
Link Invasion of the Weird Trees
....they come in all shapes and sizes. They fill the air with sweet,``fragrant scents of spring blossoms, and splash the landscape with``brilliant colors in ...
Link Neutral Plane Faults & Stem Strength
In storm damage and tree failure assessments, estimating residual strength of damaged trees is difficult and filled with complex, dynamic interactions between ...
Link New Growth Increments Sustain Stem Strength
The strength of tree stems is dependent upon stem thickness, stiffness, and ability to react to changes in aspects toward gravity and wind events. Materials ...
Link Nitrogen Mass Balance for an Urban Ecosystem
One of our first projects has been to develop a detailed nitrogen balance for the CAP ecosystem, the first for an urban ecosystem.
Link Nitrogen Transformations in Soils
Nitrogen is available for capture by a tree when an organism dies and decays, excretes nitrogen containing wastes, or sheds materials and parts.
Link Off-centered Cavity Impact on Stem Strength
One aspect of hollow stem assessments for strength loss involves various forms of stem crosssectional area damage. One of the scenarios often cited but seldom ...
Link Open Cavity Impact on Stem Strength
Assessing tree strength is a complex process. The dynamic nature of how trees resist forces include soil, tree, and environmental components. Cavities signify ...
Link Potential Allelopathy in Different Tree Species
Allelopathy is a significant tree health care issue. Allelopathy is the chemical modification of a site to facilitate better tree growth, and control ...
Link Root Control Barriers
One of the easiest and most available materials used to control root growth are various types of two-dimensional barriers. There are a number of commercial ...
Link Root Growth Requirements and Limitations
Minimizing tree root growth impacts on infrastructures requires an appreciation of how roots function and generate force. To control root growth, ...
Link Selected Literature: Nitrogen and Tree Growth
Nitrogen availability for tree health maintenance and growth is one of the most constraining essential element problems faced by shade and street trees. ...
Link Selected Literature: Root Control Methods
There has never been a time with more innovative tools and techniques available for minimizing infrastructure damage exacerbated by tree root growth. This ...
Link Soil Compaction Impacts on Tree Roots
Compaction impacts trees in many ways. Generally, compaction associated physiological dysfunctions cause systemic damage and decline, as well as failures in ...
Link Soil Constraints on Root Growth
Managed tree root growth control is required to minimize impacts on infrastructures. To constrain root growth, identification of soil attributes that limit ...
Link Stem Length & Diameter Taper Limits
Trees growth follows many mechanical rules to assure survival. In order to prevent concentrating forceat weak points, tree growth distributes loads and ...
Link Stem Strength with Closed / Centered Cavity
The structural integrity of tree stems, roots and branches are dependent upon a number of very conservative allocation and building processes. Mechanical ...
Link Strength of Solid Tree Stems
The strength of tree stems to resist bending in the wind is associated with the cross-sectional area of the stem. Strength is proportional to the diameter of ...
Link Sway Frequency in Tree Stems
Assessing potential risks in trees is difficult because of the complex and chaotic nature of gauging tree failures. Tree movements in the wind, and the ...
Link Tree Decay: An Expanded Concept
The purpose of this publication is to clarify further the tree decay concept that expands the classical concept to include the orderly response of the tree to ...
Link Tree Growth Response Systems
This publication is a synthesis of the tree growth regulation and correlation literature. General processes and systems presented here represent educational ...
Link Tree Root Growth Requirements
Roots utilize space in the soil.
