  1. 1938 USDA soil taxonomy

    The 1938 USDA soil taxonomy was a soil classification system adopted by the United States Department of Agriculture , now obsolete. The classification system used previously was developed and published in 1936 by C.F. Marbut, who was chief of the U.S. Soil Survey at that time. A drastic modification, the 1938 system was extensively revised in 1949 and remained in use until 1965. See USDA soil taxonomy for the current system.

    about Numerical taxonomy other uses of taxonomy Taxonomy disambiguation Numerical taxonomy is a Biological classification classification system in biological systematics which deals with the grouping by numerical method s of taxon taxonomic units based on their character states. ref cite web url http www.accessscience.com abstract.aspx?id 461900&referURL http 3a 2f 2fwww.accessscience.com 2fcontent.aspx 3fid 3d461900 title Numerical Taxonomy author date work www.accessscience.com publisher McGraw Hill Ltd. accessdate 13 April 2010 ref . It aims to create a taxonomy using numeric algorithms like cluster analysis rather than using subjective evaluation of their properties. The concept was first developed by Robert R. Sokal & Peter H. A. Sneath in 1963 ref Sokal & Sneath Principles of Numerical Taxonomy , San Francisco W.H. Freeman, 1963 ref and later elaborated by the same authors ref Sneath and Sokal Numerical Taxonomy , San Francisco W.H. Freeman, 1973 ref . They divided the field into phenetics in which classifications are formed based on the patterns of overall similarities and cladistics in which classifications based on the branching patterns of the estimated evolutionary history of the taxa. Note in recent years many authors treat numerical taxonomy and phenetics as synonyms despite the distinctions made by those authors. Although intended as an objective classification method, in practice the choice and implicit weighing of characteristics is, of course, influenced by available data and research interests of the investigator. What was made objective was the introduction of explicit steps to be used to create phenograms and cladograms using numerical methods rather than subjective synthesis of data.

  1. Plant taxonomy

    Unreferenced date June 2009 Plant taxonomy is the science that finds, describes, classifies, identifies, and names plant s. It thus is one of the main branches of alpha taxonomy taxonomy . Plant taxonomy is closely allied to history of plant systematics plant systematics , and there is no sharp boundary between the two. In practice, plant systematics is involved with relationships between plants and their evolution, especially at the higher levels, whereas plant taxonomy deals with the actual handling of plant specimen s. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally there is no really close agreement on wiktionary circumscription circumscription and placement of taxon taxa . See the list of systems of plant taxonomy . Identification and classification Two goals of plant taxonomy are the identification and classification of plants. The distinction between these two goals is important and often overlooked. Plant identification is the determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification manuals. The process of identification connects the specimen with a published name. Once a plant specimen has been identified, its name and properties are known. Plant classification is the placing of known plants into groups or categories to show some relationship. Scientific classification follows a system of rules that standardizes the results, and groups successive categories into a hierarchy . For example, the Family biology family to which the Lilium lilies belong is classified as follows Kingdom Plant ae Division Magnoliophyta Class Liliopsida Order Liliales ...

  1. Segregate (taxonomy)

    In Alpha taxonomy taxonomy , a segregate , or a segregate taxon is created when a taxon is split off, from another taxon. This other taxon will be better known, usually bigger, and will continue to exist, even after the segregate taxon has been split off. A segregate will be either new or ephemeral there is a tendency for taxonomists to disagree on segregates, and later workers often reunite a segregate with the mother taxon. If a segregate is generally accepted as a good taxon it ceases to be a segregate. Thus, this is a way of indicating change in the taxonomic status. It should not be confused with, for example, the subdivision of a genus into subgenus subgenera . For example, the genus Alsobia is a segregate from the genus Episcia The genera Filipendula and Aruncus are segregates from the genus Spiraea .
