We used the cytochrome oxidase subunit I ( coI ) gene DNA to barcode 117 endemic Gulf and cosmopolitan Indo–West Pacific fish species belonging to 54 families and 13 orders. Novel DNA barcodes were provided for 18 fish species ( Trachinocephalus sp., Nematalosa sp., Herklotsichthys lossei , Upeneus doriae , Trachurus indicus , Apogonichthyoides taeniatus , Verulux cypselurus , Favonigobius sp., Suezichthus gracilis , Sillago s...

This study provides data on the genetic structuring of the pipefish Syngnathus abaster in the western Mediterranean and Adriatic Seas. A total of 109 specimens were collected in brackish‐water biotopes. The control region and three other regions of the mitochondrial genome were analysed. The most relevant result was the high genetic structuring found by Bayesian inference ( BI ), maximum likelihood ( ML ) and network analyses,...
