1 6, 2, CHIN ESE BIODIV ERSIT Y 6 (2) : , May, 1998 Ξ (, ),,, Molecular phylogenetics and biodiversity conservation/ WANG Wen Abstract In recent years, it has been emphasized that the principles and methods of molecular phylogenetics should have potential and practical value in biodiversity conservation, especially in species conservation. It is a critical issue and the first step as well to identify those units which have evolutionary significance from different populations of a species concerned in species conservation. Phylogenetic relationships among those populations could shed valuable light on this issue. In addition, the data from molecular phylogenetic study are also helpful for us to understand the status and process of populations. Key words molecular phylogenetics, biodiversity conservation, evolutionary significant units, population pro2 cess Author s address Lab of Cellular and Molecular Evolution, Kunming Institute of Zoology, the Chinese A2 cademy of Sciences, Kunming , 1000,,,?
