UTILITY OF WOOD ANATOMICAL CHARACTERS IN CLADISTIC ANALYSES

Utility of Wood Anatomical Characters in Cladistic Analyses

Wood anatomy is an important source of systematically informative character information that can and should be used in cladistic phylo­ genetic analyses ofrelationships in flowering plants. However, the re­ sults ofa cladistic analysis are only as good as the characters and obser­ vations, which together comprise the data set that is analyzed. The goal of this paper is to address the former of ...

Assessment of available anatomical characters for linking living mammals to fossil taxa in phylogenetic analyses

Analyses of living and fossil taxa are crucial for understanding biodiversity through time. The total evidence method allows living and fossil taxa to be combined in phylogenies, using molecular data for living taxa and morphological data for living and fossil taxa. With this method, substantial overlap of coded anatomical characters among living and fossil taxa is vital for accurately inferrin...

Polytomies in Comparative Analyses of Continuous Characters

Felsenstein's (1985) method of phylogenetically independent contrasts was the first statistically valid parametric method for correlation and regression analysis of continuous variables measured on multiple species. One requirement of the method is that the true phylogeny linking the species in the data set be known in full, including the lengths of the branches in units of expected variance of...
