Tree Variety

A champion tree - the largest known example of its kind - represents the maximum growth of a species. The Washington State Big Tree Program has registered 1,350 trees, belonging to 869 species or cultivated varieties, that are the largest of their kind in the state. Champion Trees of Washington State documents these trees. Among them are 45 trees acknowledged by the American Forestry Association's National Big Tree Register to be the largest known examples of their kind in the United States. Sections on native and introduced trees provide the general and scientific name, circumference, height, crown spread, and AFA points (a combination of circumference, height, and crown spread), date measured, location (including street address, when relevant), and nominator's name for each champion tree. Photographs of 90 trees are included. A discussion of tree measurements explains how to measure and nominate a tree, and a list of former record trees documents trees that would be current champions had they not died or been cut. Indexes include general and scientific tree names and names of cities in which champion trees are located. Champion Trees of Washington State will be of interest to landscape architects, gardeners, foresters, and to all who wish to recognize, document, and preserve these majestic examples of biological maturity.

To explore evolutionary relationships among organisms, biologists construct and compare phylogenetic trees, not unlike the "family trees" traced for humans by genealogists. In recent years, the use of molecular data to build these trees and sophisticated computer-aided techniques to analyze them have led to a revolution in the study of cospeciation (the joint speciation of two or more lineages that are ecologically associated, such as hosts and parasites). Tangled Trees provides an up-to-date review and synthesis of current knowledge about phylogeny, cospeciation, and coevolution. The opening chapters present various methodological and theoretical approaches, ranging from the well-known parsimony approach to "jungles" and Bayesian statistical models. Then a series of empirical chapters discusses detailed studies of cospeciation involving vertebrate hosts and their parasites, including nematodes, viruses, and lice. Tangled Trees will be welcomed by researchers in a wide variety of fields, from parasitology and ecology to systematics and evolutionary biology.

B*-tree - A B*-tree is a tree data structure, a variety of B-tree, where the leaf nodes of the tree are chained together in form of a linked list. That is efficient for searching at the cost of a more expensive insertion.

Amazon tree boa - The Amazon tree boa, Corallus hortulanus, is the closest relative of the Emerald tree boa. In spite of this, it is shorter, more slender, and occurs in a variety of colors, excluding bright green.

Fruit tree propagation - Propagation of fruit trees is usually carried out asexually by grafting the desired variety onto a suitable rootstock.

Bunched logic - Bunched logic is a variety of substructural logic that, like linear logic, has classes of multiplicative and additive operators, but differs from usual proof calculi in having a tree-like context of hypotheses instead of a flat list-like structure; it is thus a calculus of deep inference. Sub-trees of the context tree are referred to as bunches; hence the name.
