“…Simulation and congruence studies suggest that, in general, incorporation of realistic evolutionary parameters into character coding and weighting increases the likelihood that the correct tree will be recovered, for both DNA sequence (e.g., Hillis et al, 1994; Huelsenbeck, 1995) and allele frequency data (e.g., Wiens, 1998Wiens, , 2000Wiens andServedio, 1997, 1998). Although application of frequency information in parsimony analysis has been controversial (e.g., see Buth, 1984;Crother, 1990;Murphy, 1993;Murphy and Doyle, 1998), compelling arguments for use of frequency-based methods have been made (Swofford and Berlocher, 1987;Wiens, 1995Wiens, , 2000. Simulation and congruence studies indicate that methods that incorporate frequency data tend to be more accurate than those that do not use this information (Cunningham, 1997;Wiens, 1998Wiens, , 2000Wiens andServedio, 1997, 1998).…”

Genetic variation and phylogenetic relationships of central Texas nontransforming spring and cave salamanders, genera Eurycea and Typhlomolge (Plethodontidae: Plethodontinae: Hemidactyliini), were examined using 25 allozyme loci and DNA sequence data for a maximum of 356 bp of the mitochondrial cytochrome b gene. Monophyly of the central Texas hemidactyliines is well supported. High levels of divergence occur among many populations and groups of populations, and there clearly are many more species in the group than previously recognized. Many have extremely restricted distributions in isolated islands of aquatic habitat. Several major monophyletic groups were identified that correspond to geographically circumscribed areas of the Edwards Plateau region. The deepest phylogenetic split in the group occurs between populations northeast versus southwest of the Colorado River. Species that have been assigned to the genus Typhlomolge are phylogenetically nested within the central Texas Eurycea; therefore, the genus Typhlomolge is placed in the synonymy of Eurycea. Continued recognition of the species E. latitans, E. nana, E. neotenes, E. pterophila, E. sosorum, E. tridentifera, and E. troglodytes is recommended, but E. neotenes appears to be restricted in range to a small geographic area, and is not widespread in the region as previously thought. The E. latitans and E. troglodytes species complexes are recognized; each consists of spring and cave populations that include those at the type localities of the latter two species, plus other populations to which they appear most closely related. Three new species from northeast of the Colorado River are described.

“…Allozyme electrophoresis offers an alternative to traditional morphological approaches to resolving issues such as these (Avise, 1975; Buth, 1984; Richardson et al , 1986; Hillis, 1987; Buth & Rainboth, 1999). It provides a large number of quantitative characters that are genetically determined.…”

A total of 281 specimens of long‐necked chelid turtles (Chelodina) were obtained from drainages of Australia, Papua New Guinea and the island of Roti in Indonesia. Ten diagnosable taxa were identified using allozyme profiles at 45 presumptive loci. Chelodina expansa, C. parkeri, C. rugosa and C. burrungandjii are in a Group A clade, C. longicollis, C. novaeguineae, C. steindachneri, C. pritchardi and C. mccordi are in a Group B clade, and C. oblonga is in a monotypic Group C clade, with each clade thought to represent a distinct subgenus. Chelodina siebenrocki is synonymised with C. rugosa. An eleventh taxon, C. reimanni, could not be distinguished from C. novaeguineae on the basis of allozyme profiles, but it is morphologically distinct. Its status is therefore worthy of further investigation. Three instances of natural hybridization were detected. Chelodina rugosa and C. novaeguineae hybridize in the Gulf country of Queensland, with evidence of backcrossing to C. novaeguineae. Chelodina longicollis and C. novaeguineae hybridize in central coastal Queensland, and C. rugosa and C. burrungandjii hybridize along their zone of contact in the plateau escarpment streams and pools. A phylogeny for the Chelodina is presented. © 2002 The Linnean Society of London, Zoological Journal of the Linnean Society, 2002, 134, 401–421.

“…Analysis of the nucleic genome is also very useful to diagnose within-population genetic diversity, which is considered as an indicator of the population viability (Haig, 1998). Allozyme electrophoresis is one of the simplest, but effective methods to address these issues (Arnold, 1992;Buth, 1984;Murphy et al, 1996). Nevertheless, it has not yet been applied to studies of E. orbicularis (and seldom even to studies of other chelonians: see Buth and Rainboth [1999] for review).…”
