“…Results of this study (2 n = 36) confirm inclusion of the Australian temperate species within an African Indo‐Pacific clade of Haliotidae species previously inferred using molecular techniques including mitochondrial cytochrome oxidase II sequencing (Degnan et al . ), protein gel electrophoresis (Brown ) and haemocyanin sequencing (Streit et al . ).…”

“…Within these clades, there appears to be a decrease in telocentric and increase in metacentric chromosome numbers. Two of these clades belong to the North-eastward radiation of the speciation model (Geiger & Groves 1999;Estes et al 2005 Indo-Pacific clade of Haliotidae species previously inferred using molecular techniques including mitochondrial cytochrome oxidase II sequencing (Degnan et al 2006), protein gel electrophoresis (Brown 1993) and haemocyanin sequencing (Streit et al 2006 This preliminary study elucidates for the first time the high chromosome morphology compatibility between H. rubra and H. laevigata (10M/ 7SM/1ST), which allows for a normal meiotic process and inheritance of a complete genetic background in the chromosome set of their F 1 interspecific hybrid of 10M/7SM/1ST. However, further cytogenetic studies may be needed to assess the likelihood of chromosomal structural abnormalities occurring during recombination which may affect the F 2 progeny and result in loss of gains made in genetic improvement programmes through the F 1 generation.…”

“…Divergence times (Myr: million years) between H. discus hannai and the congeners approximated based on the K2P distance with 2% calibration of divergence rate (Ó Foighil et al 1998) ranged from 0.4 Myr (H. discus discus and H. madaka) to 12.4 Myr (H. diversicolor aquatilis). Applying the 2% calibration of evolutionary rate may result in an underestimation of divergence time (Metz et al 1998); nevertheless, these estimates were consistently higher than those calculated using allozyme-based genetic distances (D ST ;Nei 1972) (Hara and Fujio 1992;Brown 1993) with the equation 9.55 in , except for one instance (H. midae) ( …”

Abstracts We conducted this study to find genetic evidence to distinguish the members of Pacific abalone species complex (Haliotis discus hannai, H. discus discus, H. madaka, and H. gigantea) based on microsatellite DNA markers, illustrating the potential of microsatellites for species-assignment. First, we addressed the transferability of H. discus hannai microsatellites to the three other members of Pacific abalone and five additional species (H. diversicolor aquatilis, H. midae, H. corrugata, H. fulgens, and H. rubra). Second, using the microsatellites we applied two types of individual assignment testing (the distance-based assignment and Bayesian modelbased clustering) to individuals from the Pacific abalone species. A total of 24 microsatellites were subjected to PCR trials for nine Haliotis species, and the cross-species amplification performance of these markers turned out to drop precipitously even for less divergent congeners. Within the Pacific abalone species complex, four of the 24 markers were not transferable to H. gigantea, suggesting a solid genetic boundary between H. gigantea and H. discus hannai, H. discus discus, and H. madaka. Among the three latter abalones, both assignment tests achieved approximately 90% or more success rate of assignment. The feasibility of the microsatellite markers to classify species sheds light on the genetic management of the Pacific abalone species complex.

“…Usually the values are lower, e.g. 0.001-0.131 in Helix (Lazaridou-Dimitriadou et al 1994), 0.0014.051 in Trochus and Tecfus (Borsa and Benzie 1993), 0.00@-0.007 in Haliotis (Brown 1993), 0.0004.013 in Hydrobia (Davis et al 1988), and 0.051-0.191 in Oncornelania (Davis et al 1994). Thus, the values for V. contectus are typical intraspecific distances of a rather weakly genetically differentiated gastropod species.…”

The paper describes morphometric and allozymic differences among four European species of the family Viviparidae: Viviparus contectus (Millet, 1813), V. viviparus (Linnaeus, 1758), V. acerosus Bourguignat, 1862, and V. ater (Cristofori et Jan, 1832). Fourteen continuous biometrical characters were measured. Incremental discriminant‐function analysis, principal‐component analysis, and non‐metric multidimensional scaling were applied to analysis of the morphometric differences. All the techniques confirmed a similar picture: a slight morphometric differentiation, with the variability ranges of the species overlapping. On the other hand, the allozymic differentiation, studied at 12 loci, eight of them intra and/or interspecific polymorphic, is much better marked, the intraspecific Nei's distances among the four V. contectus populations ranging from 0.0014 to 0.0397, mean 0.0166, and interspecific distances ranging from 0.2306 (V. ater–V. acerosus) to 0.9888 (V. contectus 2 and V. viviparus), mean 0.6871. The allele frequencies and genetic distances (Nei's distance and Cavalli‐Sforza and Edwards’chord distance) were used to compute maximum likelihood, additive Fitch–Margoliash and ultrametric Fitch–Margoliash trees. All the trees presented a similar pattern, but the maximum‐likelihood and additive trees, based on Cavalli‐Sforza and Edwards’distance, seem to reflect the phylogeny best. The results are compared with the most parsimonious phylogenies inferred for radular, soft‐part morphology and anatomy, and opercular data from other papers by us, and the inferred phylogenies are also compared. Although the inferred molecular and morphological phylogenies are little different in topology, the amount of evolution along the corresponding branches (measured as the number of changes averaged over all reconstructions) is very different, the value of correlation coefficient between the two phylogenies being statistically insignificant. The occurrence of interspecific hybrids is discussed, and the isolation‐by‐competition mechanism is postulated. The probable origin of V. viviparus from a founder population extremely restricted in number is stressed. The possible history of the group is briefly discussed. The species is suggested to have originated in an unusual habitat of melt water at a glacier foreland that could have promoted genotypic differentiation and sympatric speciation.
