“…Thus, the pattern of population divergence may reflect either the isolation of populations or the occasional opportunity to colonise free habitats. The strong genetic divergence of the Villena population (Doadrio et al 1996, Fernández-Pedrosa et al 1995, for example, apparently reflects its ecological divergence (Perdices et al 2001).…”

“…Palaeogeological studies indicate that present Mediterranean coastal lagoons originated mainly in postglacial times after the last sea transgression (Flandrian, 6000 years bp) from coastal bays closed by sandy cords, deltas or littoral plains (Zazo 1999). Evidence of a recent divergence of coastal populations, or of high gene flow until recent times, can be observed in the moderate proportion of individuals that could be classified into their original baseline population in the assignment test (Table 4) and in the low mitochondrial divergence between the Santa Pola and Albuixec populations compared to the divergence of the inland Villena population (Fernández-Pedrosa et al 1995). In addition, the lack of regional equilibrium could reflect recent anthropogenic changes and disturbances that limit gene flow.…”

“…Aphanius species typically thrive in environments that are not suitable for other fishes, and thus often lack direct competitors and major predators (Clavero et al 2007). However, several Aphanius species have low population sizes and/or small areas of occurrence, and are today considered endangered due to drainage, land-use, and pollution around their native habitats (e.g., Fernández-Pedrosa et al 1995;Moreno-Amich et al 1999). Moreover, the artificially introduced mosquitofish (Gambusia) may compete with Aphanius, and many native Aphanius populations are seriously threatened by Gambusia in the Mediterranean area, Turkey and the Near East (e.g., Wildekamp et al 1999;Oliva-Paterna et al 2006).…”

The endangered cyprinodont Aphanius ginaonis (Holly, 1929) from southern Iran is a valid species: evidence from otolith morphology

et al. 2009

Aphanius Nardo, 1827 (Actinopterygii, Cyprinodontidae) is a widely distributed genus in the Mediterranean and Persian Gulf area and includes several endangered species. The otolith morphology in Aphanius is known to represent a valuable tool for the taxonomy, and is also indicative for the genetic diversity of a particular population. The present study focuses on the otoliths of the endangered A. ginaonis (Holly, 1929), which is endemic to the Geno hot spring in southern Iran. The taxonomic status of A. ginaonis has repeatedly been questioned, and some scholars have argued that it merely represents a morphological variation of the widespread A. dispar. We present a comparison of the otolith morphology of A. ginaonis (52 specimens) with that of A. dispar (Rüppell, 1828) from the Mehran River Basin (southern Iran) (17 specimens) and an A. dispar population from the Persian Gulf coast of the United Arab Emirates (32 specimens). Our data obtained from SEM pictures, otolith morphometry and statistical analyses suggest that A. ginaonis represents a valid species. In A. ginaonis individuals with a standard length exceeding 23 mm, the otolith variables lengthheight and rostrum length represent useful complementary diagnostic characters discriminating this species from other Aphanius species. Besides ontogenetic variation, we found extremely high otolith form variability in A. ginaonis, including some otoliths with a morphology distinctly deviating from the basic morphology type. We hypothesize that these variations may be a result of the artificial introduction of A. dispar into the Geno hot spring during the last years and subsequent hybridisation.

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.
