A phenetic and cladistic study of spermatozoal ultrastructure in the Oligochaeta (Annelids)

  title={A phenetic and cladistic study of spermatozoal ultrastructure in the Oligochaeta (Annelids)},
  author={Barrie G. M. Jamieson},
Spermatozoal ultrastructure of nine oligochaete families has been examined for congruence with phylogenetic and taxonomic systems for the Oligochaeta based on general morphology, particularly the holomorphological hennigian analysis of Jamieson (1978a, 1980, 1983). Estimation of congruence has been made following phenetic and cladistic (phylogenetic) analysis. Correspondence, in phenograms and phylograms, of sperm types with taxonomic and phylogenetic groupings previously recognized is… CONTINUE READING
