DNA Hybridization and Avian Systematics: Introduction,ics. Subsequently the editors of . invited representatives of each side of the discussion to present their conflicting views. The main discussion of the roundtable centered on the application by Dr. C. Sibley and his colleagues of DNA hybridization to the phylogenetic relationships of bird taxa.

DNA Hybridization and Avian Phylogenetics, employed, but so, too, are alternative methods of analysis, including phenetics, evolutionary systematics, and cladistics. The last decade has seen more advance in our knowledge of avian relationships than perhaps during any other comparable period, and given the growing number of systematists, we

DNA Hybridization and Avian Phylogenetics, to the reconstruction of the phylogenetic relationships among living birds. Our purpose is to respond to Cracraft’s questions, to correct misunderstandings, and to reaffirm our confidence in DNA hybridization as a valuable and effective method for the reconstruction of phylogenies.

Evolutionary Implications of Phenotypic Plasticity in Plants,defined as variation in phenotypic expression of a genotype that occurs in response to particular environmental conditions and which enhances the capacity of the individual to survive and reproduce under those conditions. A distinction is made [following Dobzhansky (1969) and Harper (1982)] between
