The present book entitled “Introductory Biosystematics and Taxonomy” is primarily intended to offer text material for the postgraduate/graduate curriculum of most universities. Apart from the traditional topics in taxonomy, the latest topics as per the advancement in the field of taxonomy have been included. The already existing books on the subject have been thoroughly deficient for such topics. Therefore, the present book is concise and covers topics such as DNA Barcoding, Histochemical basis of taxonomy, Molecular clocks, Cladistics, Biodiversity indices, Curetting, Collections and preservation of animals and Ethics in research etc. All necessary and relevant chapters have been included with rich and updated text. The present book will fulfil the purpose and meet out the requirements of the students. It will be equally important for those who are preparing for various competitive examinations for their syllabi on taxonomy/systematics. It is hoped that teaching faculties, research workers who specialize in other fields but utilize taxonomic information will also find it useful.
