“…Our studies show molecular differentiation in agreement with the geographical distance of the populations, while the osteological differentiation cannot be interpreted biogeographically. The inconsistency between allozymic, molecular, and morphological data has also been found in some species of Cyprinodontiformes (Agnese et al, 1987;Bernardi & Talley, 2000;Echelle et al, 2000). According to Jerry & Cairns (1998), the discrepancy between the results of different approaches could be explained by the fact that morphological variation partly reflects genetic differences, or that differences in morphology do not represent the phylogenetic history of populations, but that they are primarily ecophenotypic, or a consequence of local response to dissimilar environments.…”

“…Mitochondrial DNA has been used in population studies due to its limited length, maternal transmission, and its elevated evolutive rate (Brown et al, 1979;Wilson et al, 1985) and particularly the mitochondrial control region (D-loop) has been found to be a good population marker (Bernardi, 2000). In the cyprinodontiforms, the study of mitochondrial DNA has shown an elevated genetic divergence among populations of A. iberus (Fernandez-Pedrosa et al, 1995), Cyprinodon macularius (Echelle et al, 2000), Fundulus paruipinnis (Bernardi & Talley, 2000) and several species of Aphanius (Hrbek & Meyer, 2003)-The integration of morphological and molecular data is an effective method for the comprehension of evolutionary models of a number of taxa (Baker et al, 1998) while the practice of combining independent data sets (e.g., molecular and morphological data sets) into a single phylogenetic analysis continues to be debated in literature (Farias et al, 2000). In the present study, the control region of mitochondrial DNA was analyzed for the first time in populations of the cyprinodontid A. fasciatus.…”

The study of three Sicilian populations of Aphanius fasciatus was carried out by examining the mitochondrial control region and the morphology of the bony elements of the skull and vertebral column. The osteological and molecular data obtained indicate a marked differentiation between the populations examined resulting from their isolation, even if the dendrograms of the two approaches are dissimilar. Molecular investigations show that populations are characterized by haplotypes that are well defined in relation to the limited gene flow; while the osteological investigation may account for appreciable environmental influences on the morphological characters.KEY WORDS: Teleost -Aphanius fasciatus -Osteology -Multivariate and univariate analysis -Mitochondrial DNA -D-loop.

A study of osteological and molecular differences in populations of Aphanius fasciatus Nardo 1827, from the central Mediterranean (Teleostei, Cyprinodontidae)

et al. 2006

Nine populations of Aphanius fasciatus Nardo, 1827 from the central Mediterranean were analysed by examining the mitochondrial control region and the morphology of the bony elements of the skull and vertebral column, to study the degree of intraspeciWc diVerentiation of A. fasciatus considering the level of isolation of the diVerent populations and the palaeogeographic history of the central Mediterranean area. Both the molecular and morphological analyses diVerentiate between the populations, even if the topologies of the two trees are diVerent. The molecular results show that the nine populations are characterised by haplotypes that are well deWned in relation to a probably limited gene Xow; while, as regards the morphological data the diVerentiation found could be explained in terms of the geographic isolation of the various populations, although the inXuence of environmental factors, which diVer greatly between the various sites where the populations live, cannot be ruled out.

“…The complex comprises three species, the now extinct Monkey Springs Pupfish, Cyprinodon arcuatus, of southern Arizona (Minckley et al 2002) and two extant species, the Desert Pupfish, C. macularius, which once ranged widely in the Colorado River system of southern Arizona and California and northern Sonora and Baja California del Norte, and C. eremus, which is known only from Quitobaquito Springs in southern Arizona and a short reach of the Río Sonoyta in northern Sonora (Miller 1943;Hendrickson and VarelaRomero 1989;Echelle et al 2000). Because of dramatic declines in distribution and abundance, the Desert Pupfish complex is listed (as C. macularius) as endangered by the United States (Federal Register 51(61):10842) and Mexico (31 July 2007; http://www.conabio.gob.mx/conocimiento/ ise/fichasnom/).…”

“…Previous studies of genetic variation in natural populations of the Desert Pupfish complex consist of allozyme surveys of populations in the United States (Turner 1983;Dunham and Minckley 1998) and a mitochondrial DNA (mtDNA) survey throughout the range of the complex, including the known populations in Mexico (Echelle et al 2000). In this paper, we provide a survey of microsatellite DNA variation in the samples assayed for mtDNA variation by Echelle et al (2000).…”

Data from 10 microsatellite DNA loci were used to describe the genetic structure of the two extant species (Cyprinodon macularius and C. eremus) of the endangered Desert Pupfish complex of southwestern United States and northwestern Mexico. Variation at microsatellite loci was significantly correlated (Mantel test) with that of previous mtDNA results, both for the complex and for the relatively wide-ranging C. macularius alone. Both species showed unusually high levels of microsatellite diversity for non-marine fish (H e = 0.84-0.93; A R = 11.9-17.0). There was evidence (R ST [ F ST ) that the two extant populations of C. eremus have been isolated sufficiently long for mutation to contribute significantly to genetic divergence, whereas divergence among the nine assayed populations of C. macularius could be attributed to genetic drift alone. Correspondingly, 10% of the diversity in C. eremus was attributable to differences between the two populations, whereas, for C. macularius, only 2.7% was attributable to among-population variation. Within C. macularius, a small (0.8%), but statistically significant, portion was attributable to differences between populations in the Salton Sea area and those on the lower Colorado River delta. The two populations of C. eremus and five groups of populations of C. macularius are recommended as management units for conservation genetics management of the two species.
