Two new species of Aphanius are described from the Kol drainage in southern Iran (Aphanius darabensis n. sp.) and the endorheic Kavir Basin in northern Iran (A. kavirensis n. sp.), and compared with eight closely related species. Aphanius darabensis n. sp. is sister to A. shirini, from which it is distinguished by molecular characters (cytochrome b) and the combination of three morphological ch...

A new species of tooth-carp, Aphanius arakensissp. n., is described from the Namak Lake basin in Iran. The new species is distinguished by the congeners distributed in Iran by the following combination of characters: 10-12 anal fin rays, 28-32 lateral line scales, 10-13 caudal peduncle scales, 8-10 gill rakers, 12-19, commonly 15-16, clearly defined flank bars in males, a more prominent pigment...

Phylogenetic relationships of a subset of Aphanius fish comprising central Anatolia, Turkey, are investigated to test the hypothesis of geographic speciation driven by early Pliocene orogenic events in spite of morphological similarity. We use 3434 aligned base pairs of mitochondrial DNA from 42 samples representing 36 populations of three species and six outgroup species to test this hypothesi...

Systematic assignment of fossil otoliths is virtually always based on studies of otolith morphology and subsequent comparisons with otoliths from collections and/or literature. Although this usually represents a practical method, comparisons and subsequent evaluation may be biased by subjective criteria used in the individual descriptions. Quantitative morphometric studies focusing on variation...

Aphanius marassantensis, new species, is described from the Kızılırmak River drainage in northern Anatolia based on colouration, meristic and morphometric characters, and the mtDNA COI barcode region. It is distinguished from other Anatolian Aphanius by one or several of the following characters: a stout body shape (BD/SL 28.2-39.6%), complete scale cover, and 25-28 scales along the lateral lin...

The wrinkle layer is a dorsal shell structure occurring in a number of ammonoids, but its function is still debated. Here, we describe, from Moroccan material of the Early Carboniferous species Maxigoniatites saourensis (Pareyn, 1961), the most conspicuous wrinkle layer known within the Ammonoidea. This additional shell layer occurs in the ventrolateral portion of the adult body chamber and for...

To test vicariant speciation hypotheses derived from geological evidence of the closing of the Tethys Sea, we reconstruct phylogenetic relationships of the predominantly fresh-water killifish genus Aphanius using 3263 aligned base pairs of mitochondrial DNA from samples representing 49 populations of 13 species. We use additional 11 cyprinodontid species as outgroup taxa. Genes analysed include...

Despite the ubiquity of terrestrial gastropods in the Late Pleistocene and Holocene archaeological record, it is still unknown when and how this type of invertebrate resource was incorporated into human diets. In this paper, we report the oldest evidence of land snail exploitation as a food resource in Europe dated to 31.3-26.9 ka yr cal BP from the recently discovered site of Cova de la Barria...

Aphanius pluristriatus (Jenkins, 1910) (Cyprinodontidae) is a poorly known species from Fasa, located in the Mond River drainage system, east of Shiraz, southern Iran. It has not been investigated since its first description, its validity has been questioned and a synonymy with A. sophiae (Heckel, 1849) has been suggested. In this study, we describe a new collection of Aphanius specimens from t...

When euryhaline teleosts are adapted to waters of salinities higher than the osmolality of plasma an increase in drinking rate has been observed (Lotan, 1969; Maetz, 1970; Maetz & Skadhauge, 1968; Potts et al. 1967; Shehadeh & Gordon, 1969). This is to be expected since drinking, and absorption of salt (NaCl) and water through the intestinal wall, is the only way for the fish to get water to ma...
