Methods and Procedures of Sampling, Preservation and Identification for Fish Taxonomy Studies

چکیده
Taxonomyhas two important roles: to name organisms and to classify them. Classifications are useful because they contain information about relationships.All species in the same genus should share many behavioral, biochemical, ecological and biological properties because they are closely related evolutionarily. The effect of pollution on a species at one location should be similar to the effect on a close relative living in a different area. Those in the same family (next primary category up) similarly shares many but fewer features. Classifications thereby have predictive value. The changing nature of classifications and scientific names (because of changing ideas of relationships and because of technical [nomenclatural] rules changes) makes it almost impossible to know under which species, genus, or even family names one will find pertinent information in the prior literature or in specimen collections.Another problem is that scientific names are frequently misspelled in scientific publications, in collection records for museum holdings and by abstracting services. Often a name is misspelled because the spelling as originally presented was not verified by subsequent workers. Therefor, proper identification of organisms is necessary to describe the species at any level, if decisions are to be made about preserving species, then relationships among species must be known to determine the evolutionary uniqueness of the species.

A Review of Fish Taxonomy Conventions and Species Identification Techniques
Taxonomists, ecologists, geneticists or researchers from other biological fields who wish to adopt fish as a constituent of their studies often become discouraged when they find that ichthyology is a complex subject. In fish-based studies, the failure to recognize fishes as distinct biological units can lead to wrong diagnosis. Hence, this review paper attempts to clarify and discuss the latest...
متن کاملThe current status of Pythium species in Iran: challenges in taxonomy
Pythium species are cosmopolitan, fungus-like oomycotes which may cause diseases in plants, animals and even human beings. Some of the species, however, are saprophytes and also well-proven biological control agents of plant pathogenic fungi. Since 1968, when the first Pythium species was reported from Iran, ca 44 species, two varieties, and five groups of this genus have been reported from dif...

متن کاملObjects Identification in Object-Oriented Software Development - A Taxonomy and Survey on Techniques
Analysis and design of object oriented is onemodern paradigms for developing a system. In this paradigm, there are several objects and each object plays some specific roles. Identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. The f...
