Problems in Cladistic Classification: Higher-Level Relationships in Land Plants

Recent cladistic analyses of green plants recognize an extensive hierarchical series of relatively well-supported monophyletic groups. Translating this hierarchical pattern of relationships into a usable and informative written classification is important for purposes of scientific communication, research and teaching. However, in the context of the "Linnean" hierarchy, as manifested in the cur...

Stability of cladistic relationships between Cetacea and higher-level artiodactyl taxa.

Over the past 10 years, the phylogenetic relationships among higher-level artiodactyl taxa have been examined with multiple data sets. Many of these data sets suggest that Artiodactyla (even-toed ungulates) is paraphyletic and that Cetacea (whales) represents a highly derived "artiodactyl" subgroup. In this report, phylogenetic relationships between Cetacea and artiodactyls are tested with a co...
