“…None of the A. boyeri individuals analysed here presented punctuation, seemingly contradicting the hypothesis of the three Atherina species formulated by Trabelsi et al (2002b). Conversely, we found statistically quantified differences in body shape among the 11 groups of the large-scale sand smelts from different habitats (inland lakes, coastal lagoons and sea sites), for the first time.…”

“…Other recent studies (Trabelsi et al 2002a) and molecular investigations (Avise & Wollenberg 1997;Gilles et al 2000) clearly identified three groups, which were proposed to be elevated to the rank of species, distinguished on the basis of morphology, morphometry and biochemistry. The first species-group consisted of non-punctuated marine specimens (A. boyeri), the second species of punctuated marine specimens (A. punctata), and the third, lagoon specimens (A. lagunae) (Trabelsi et al 2002b). Klossa-Kilia et al (2002) demonstrated, through mitochondrial DNA analyses, the existence of two separate populations: the lagoon and the marine populations.…”

In this study, specimens of the large-scale sand smelts Atherina boyeri, a fish species occurring in different environments (freshwater lakes, coastal lagoons, sea), were examined for their body shape and the differences observed were analysed statistically. The variation of external morphology was investigated in 11 populations from different environments. The morphology was characterized by means of geometric morphometrics and compared; results showed that the phenotypic (morphometric) distances among samples differed significantly by Relative Warp Analysis, specimens from the coastal lagoon being clearly separated from those belonging to lake and marine populations on the first RW1 axis and the latter ones separated on the RW2 axis. The results obtained also show the absence of a gradient of shape differences according to lake-lagoon-sea origin or eidonomic convergence in fish from environments with similar (high) trophic productivity. An integration of geometric morphometric data in a multidisciplinary approach with genetic, biochemical, geographical, molecular and other morphological analyses is necessary to describe the phylogenetic relationships of Atherinidae, shedding light on some ambiguous taxonomic ranks.

“…This distinguished punctated (spotted) and non-punctated fishes, as well as those restricted to marine, brackish and freshwater habitats (e.g. Astolfi et al, 2005;Klossa-Kilia et al, 2002;Trabelsi et al, 2002a). Francisco et al (2008) provided a comprehensive phylogenetic analysis of the eastern Atlantic and Mediterranean species of Atherina based on mitochondrial DNA, and revised their taxonomy, proposing three distinct species within the A. boyeri complex: A. boyeri (inhabiting lagoons and freshwater bodies), as well as ''punctuated'' and ''non punctuated'' forms (both typically present in marine conditions).…”

a b s t r a c tSand-smelts are small fishes inhabiting inshore, brackish and freshwater environments and with a distribution in the eastern Atlantic and Mediterranean Sea, extending south into the Indian Ocean. Here, we present a broad phylogenetic analysis of the genus Atherina using three mitochondrial (control region, 12S and 16S) and two nuclear markers (rhodopsin and 2nd intron of S7). Phylogenetic analyses fully support the monophyly of the genus. Two anti-tropical clades were identified, separating the South African Atherina breviceps from the north-eastern Atlantic and Mediterranean Atherina' species. In European waters, two groups were found. The first clade formed by a well supported species-pair: Atherina presbyter (eastern Atlantic) and Atherina hepsetus (Mediterranean), both living in marine waters; a second clade included Atherina boyeri (brackish and freshwater environments) and two independent lineages of marine punctated and non-punctated fishes, recently proposed as separate species. Sequence divergence values strongly suggest multiple species within the A. boyeri complex.

“…Phenotypic polymorphism is especially high in A. boyeri. Before 1969 nearly 20 distinct species were described in the literature until Kiener & Spillman (1969, 1972 (KlossaKilia et al 2002, Trabelsi et al 2002a, 2002b. According to these studies, based on both morphological and molecular data, the species known as A. boyeri should be considered as a complex of 3 different species (2 marine and 1 living in lagoons), which should be renamed according to their distribution and to the presence of dark spots along the lateral line.…”

The role of transition environments, such as lagoons or deltas, in shaping the geographical pattern of genetic variability may be investigated through the analysis of population structure in the species living in these habitats. Several fish species are strictly bound to deltas or coastal lagoons for at least part of their life cycle. This paper reports the analysis of mitochondrial DNA variability in several populations of Atherina boyeri (Risso, 1810) sampled along the north Mediterranean coasts from the Atlantic Ocean to the Black Sea. The results show a high genetic structure among populations, probably due to the deep fragmentation of the lagoon environments in which this species spends most of its life cycle. On the other hand, a clear phylogeographic pattern and a significant positive correlation between genetic and geographical distances support the hypothesis of gene flow among populations, probably due to an imprecise anadromic behaviour from the lagoons to the close coastal sea, which allows for an exchange of individuals between contiguous populations. Our results are in good agreement with those previously obtained on the same species by RAPD techniques. Our analysis among different Atherina genera are also compatible with the most recent classification of these species based on morphological and genetic characters.
