Definition and basic concepts of biosystematics and taxonomy

  • Importance and applications of biosytematics in biology
  • Material basis of biosystematics-different attributes
  • Trends in biosystematics-

        Chemotaxonomy

        Cytotaxonomy

        Molecular taxonomy

Dimensions of speciation and taxonomic characters  

  • Dimensions of speciation – types of lineage changes,  production of additional lineage
  • Mechanisms of speciation in panmictic and apomictic species
  • Species concept- Species category, different species concept, subspecies and other infra specific categories
  • Theories of Biological classification , Hierarchy of categories

Taxonomic characters – different kinds, origin of reproductive isolation

Procedure keys in taxonomy

  • Taxonomy procedures-Taxonomic collections, preservations, curetting process of identification
  • Taxonomic keys-Different kinds of Taxonomic keys, their merits and demerits
  • Systematic publication-Different kinds of publications
  • Process of typification and different zoological types
  • International code of Zoological nomenclature (ICZN) – its operative principles, interpretation and application of important rules, Zoological nomenclature, formation of scientific names of various taxa.
  • Evaluation of biodiversity indices:
  • Shannon-Weinner index, dominance index
