Taxonomical Aids

Introduction   Taxonomical aids are the collections of samples or preserved organisms which help in extensive research for the identification of various taxonomic hierarchies  

An essential process , because: taxonomic categorization helps in identifying many organisms necessary in various fields like agriculture, industries, bio resources, etc .   Used for identification and classification of an organism, and information gathered is stored along with the specimens   Main source which helps us in studying the relative level of a group of organisms, their taxonomic hierarchy and taxonomic rank Introduction   Taxonomical aids are the collections of samples or preserved organisms which help in extensive research for the identification of various taxonomic hierarchies  

They are required for:   Taxonomic studies of various species of plants, animals, and other organisms, which require correct classifications and identification   Identification of organisms requires laboratory and field studies Introduction   Taxonomical aids are the collections of samples or preserved organisms which help in extensive research for the identification of various taxonomic hierarchies

Zoological Parks Places where wild animals are kept in protected environments under human care and which enable us to learn about their food habits and behaviour

Other Taxonomical Aids Monographs Manuals Flora Key

Taxonomical aid used for identification of plants and animals based on the similarities and dissimilarities   Key Based on the contrasting characters generally in a pair called as the couplet Represents choice made between two opposite options that results in acceptance of only one and rejection of the other Separate taxonomic keys are required for each taxonomic category such as family, genus and species for identification purposes Keys are analytical in nature and e ach statement present in the key is called a lead

Flora Monographs   Contains actual account of the habitat and distribution of plants of a given area Provides index to the plant species found in a particular area   Useful in providing information for identification of names of species found in an area   Contain information on any one taxon
