Additional checking of the phenetic analysis was done using the PC-based package NTSYS-PC 1.3. This software is not available over the Internet (at least not legally), but information about the program is available from its publishers, Exeter Software.
Phylogenetic analyses and various tests of the robustness of the conclusions were carried out using PAUP 3.1.1, a Macintosh-based program implementing various parsimony algorithms, written by David Swofford and published by the Smithsonian Institution. At this time little Web-based information is available on PAUP, and version 3.1.1 is not available. A new, greatly expanded version, PAUP*, is supposedly due to be released soon by Sinauer Press. See this list of phylogenetic analysis computer programs, maintained at the Tree of Life project, for information about PAUP.
Component analyses and jacknife tests were done using various component programs of the PHYLIP package. This program is available as freeware from the author's Website.
For those interested in other programs for phylogenetic and classification applications, UCMP maintains this list of software available on the WWW.
