Abstract Systematic assignment of fossil otoliths is virtually always based on studies otolith morphology and subsequent comparisons with from collections and/or literature. Although this usually represents a practical method, evaluation may be biased by subjective criteria used in the individual descriptions. Quantitative morphometric focusing variations extant fishes have been conducted fisheries research, mostly Fourier shape analysis related methods. However, regard to otoliths, these...
The Arabian cyprinodontid Aphanius dispar (Rüppell, 1829) is known to show considerable morphological variation. It has remained unknown, however, whether this variation a result of environmental differences or allopatric divergence owing geographical isolation. In study, 11 populations A. from three geographically separated basins were analysed, that is, the Makran Basin (I, one river system), Hormuzgan (II, five rivers and hot springs) Helleh (III, two in southern Iran. Statistical...
Background The classification of gobioid fishes is still under discussion. Several lineages, including the Eleotridae and Butidae, remain difficult to characterize because synapomorphies are rare (Eleotridae) or have not yet been determined (Butidae). Moreover, fossil record these groups scarce. Results Exceptionally well-preserved fish fossils with otoliths in situ from uppermost Oligocene sediments (≈23–24 Mio. y. ago) Southern France provide most in-depth description a date. species was...
Among the species of Aphanius Nardo, 1827, dispar (Rüppell, 1828) is most common taxon and has long been viewed as representing a group rather than single species. This study provides comprehensive data on phylogenetic relationships, morphology, otoliths within A. group, including description new Our demonstrate that "true" restricted to Red Sea drainages all other populations hitherto identified actually represent separate Four main clades are defined named for geographic areas in which...
Abstract Aphanius Nardo is a large genus of teleost fishes in the Old World, with 19 described species. Several these species have only recently been recognized and additional can be expected from isolated populations remote areas. We show here that otolith morphology statistical analyses variables contribute to detection genetic differentiation . studied samples eight dispar southeastern part Arabian Peninsula. Two originate freshwater habitats far inland probably since late Holocene some...
A new species of tooth-carp, Aphanius arakensis sp. n., is described from the Namak Lake basin in Iran. The distinguished by congeners distributed Iran following combination characters: 10–12 anal fin rays, 28–32 lateral line scales, 10–13 caudal peduncle 8–10 gill rakers, 12–19, commonly 15–16, clearly defined flank bars males, a more prominent pigmentation along added relatively big blotches middle and posterior segments females, short but high...
A substantial number of species within the tooth-carp Aphanius Nardo, 1827 (Cyprinodontidae, Teleostei) has been re-corded from endorheic drainage systems Iran, and several isolated populations in these may deserve status. Descriptions have based mainly on morphological molecular data; how-ever, characters related to fish scales not up now intensively studied employed for identifica-tion belonging this genus. The objective study is test as whether (i) scale surface morphology, (ii)...
Morphologically similar populations of Aphanius that are currently considered as A. sophiae inhabit the endorheic Kor River Basin in Zagros Mountains. Using genetic analysis based on mtDNA (cytochrome b), combined with examination morphology (morphometry, meristics, otoliths), we discovered what is thought to be actually two distinct species, one which described shirini sp. n. The males new species can distinguished from those all other Iranian inland by having only 7–10 clearly defined...
Two new species of Aphanius are described from the Kol drainage in southern Iran (Aphanius darabensis n. sp.) and endorheic Kavir Basin northern (A. kavirensis sp.), compared with eight closely related species. sp. is sister to A. shirini, which it distinguished by molecular characters (cytochrome b) combination three morphological characters: 9-18 flank bars males (vs. 7-10), females irregular vertical patches brown color on prominent dark blotches round or shape), symmetrically-shaped...
