-We examined patterns of variation in skeletal morphometrics (29 characters), allozymes (34 loci), mitochondrial DNA (mtDNA) restriction sites (n = 74) and fragments (n = 395), and mtDNA sequences (1,739 bp from cytochrome b, ND2, ND6, and the control region) among all species of Toxostoma. The phenetic pattern of variation in skeletal morphometrics generally matched traditional taxonomic group...

Abstract The Zagros Mountains represent a strategic geographic region near the junction of Africa, Europe, and Asia, valleys within mountain range likely correspond to migration corridors used by archaic modern humans. Ghar-e Boof, key archeological site in southern Zagros, is located at an altitude 905 m.a.s.l. Dasht-e Rostam Fars Province, Iran. On basis lithic artifacts radiocarbon luminesce...

Purpose. To investigate the current state of nearshore fish communities and peculiarities aquatic plants zoobenthos distribution in Vita River mouth Dnipro channels. Methodology. The study was carried out summer autumn 2022 at 4 sampling sites 3 straits Zhukov Island area. Fishes were caught by a beach seine (6 m length, 1.5 height, сm mesh size). Two to three hauls made every site depending on...

—Splittail Pogonichthys macrolepidotus is a relatively large cyprinid endemic to the San Francisco Estuary watershed. During late winter and early spring, splittails migrate from the estuary to upstream rivers and floodplains for spawning. During 2002 and 2003, we examined the diet composition, muscle stable isotope signatures (dC and dN), and growth rates of age-0 splittails in the four primar...

DNA barcoding is a fast and reliable tool for species identification, and has been successfully applied to a wide range of freshwater fishes. The limitations reported were mainly attributed to effects of geographic scale, taxon-sampling, incomplete lineage sorting, or mitochondrial introgression. However, the metrics for the success of assigning unknown samples to species or genera also depend ...
