Title: | Do cladistic and morphometric data capture common patterns of morphological disparity? | Contributor(s): | Hetherington, Alexander J (author); Sherratt, Emma (author); Ruta, Marcello (author); Wilkinson, Mark (author); Deline, Bradley (author); Donoghue, Philip C J (author) | Publication Date: | 2015 | Open Access: | Yes | DOI: | 10.1111/pala.12159 | Handle Link: | https://hdl.handle.net/1959.11/17797 | Abstract: | The distinctly non-random diversity of organismal form manifests itself in discrete clusters of taxa that share a common body plan. As a result, analyses of disparity require a scalable comparative framework. The difficulties of applying geometric morphometrics to disparity analyses of groups with vastly divergent body plans are overcome partly by the use of cladistic characters. Character-based disparity analyses have become increasingly popular, but it is not clear how they are affected by character coding strategies or revisions of primary homology statements. Indeed, whether cladistic and morphometric data capture similar patterns of morphological variation remains a moot point. To address this issue, we employ both cladistic and geometric morphometric data in an exploratory study of disparity focussing on caecilian amphibians. Our results show no impact on relative intertaxon distances when different coding strategies for cladistic characters were used or when revised concepts of homology were considered. In all instances, we found no statistically significant difference between pairwise Euclidean and Procrustes distances, although the strength of the correlation among distance matrices varied. This suggests that cladistic and geometric morphometric data appear to summarize morphological variation in comparable ways. Our results support the use of cladistic data for characterizing organismal disparity. | Publication Type: | Journal Article | Source of Publication: | Palaeontology, 58(3), p. 393-399 | Publisher: | Wiley-Blackwell Publishing Ltd | Place of Publication: | United Kingdom | ISSN: | 1475-4983 0031-0239 |
