The Erdős–Pósa property forms a pivotal concept in modern graph theory by establishing a profound duality between the problems of packing and covering cycles or other substructures. At its ...

Tree-height distributions show consistently smaller variation and less positive skewness than the distributions of trunk diameter and crown depth (tree height minus height of the lowest branch). This ...

The influence of tree dimensions on efficiency of height growth was analyzed for Acer saccharum (sugar maple), an important shade-tolerant species of the northeastern United States. Support efficiency ...
