Biosystematics is the study of biological diversity and its origins. It focuses on understanding evolutionary relationships among organisms, species, higher taxa, or other biological entities, such as genes, and the evolution of the properties of taxa including intrinsic traits, ecological interactions, and geographic distributions. An important part of systematics is the development of methods for various aspects of phylogenetic enference and biological nomenclature/classification. Biosystematics is organized into eight chapters. Chapter one focuses on introduction of biosystematics. The progress in biosystematics is also highlighted. Buiosystematics has for some considerable time been one of the most popular approaches of systematic botany, often contrasted to tradiitonal 'herbarium botany'. The concept is employed for taxonomic work on living material, for instance through detailed field studies, and also encompasses cytotaxonomy, pollination biology, and reproductive biology, experimanetal, cultivation, hybridization and crossing experiments, etc. Chapter three gives an ...
