A review of the genus Eugaster Serville, 1838 (Orthoptera, Tettigoniidae, Hetrodinae): a multifaceted approach.

Overall coloration, size and thoracic morphology have formed the basis for taxonomic differentiation of taxa within the genus Eugaster at specific or subspecific levels over the years. The present study employs a range of methods to examine the morphology of 58 specimens (18♂♂ and 40♀♀) from Morocco, Algeria and Tunisia, collected from altitudes varying between 10 and 1795 metres AMSL. Moroccan sampling sites include localities on both the north and south of the High Atlas and from either side of the Middle Atlas, i.

A molecular approach towards taxonomic identification of elasmobranch species from Maltese fisheries landings.

The mitochondrial genome, through the application of DNA barcoding, provides a powerful tool for identifying species even when specimens are either incomplete or belong to species that exhibit cryptic diversity. In fisheries management accurate identification of whole or part of the specimens landed is a fundamental requirement for the conservation of species affected directly or indirectly by the fisheries activities. In this study cytochrome c oxidase subunit I (COI) and NADH dehydrogenase subunit 2 (ND2) sequences were used to genetically distinguish 36 elasmobranch species collected from Maltese (Central Mediterranean) commercial fisheries landings.
