Abstract The euphausiid genus Stylocheiron includes species with biogeographical distributions spanning multiple ocean basins. Despite their circumglobal distributions, the show low levels of genetic diversity and little or no evidence population structure based on mitochondrial cytochrome oxidase I (COI) barcode region, exception a possible cryptic within affine. elongatum showed < 1% v...

The study of roach for the metazoic parasites' presence allowed to detect D. crucifer, chromatophorum. P. homoion homoion, C. laticeps, O. felineus, ovatus, R. campanula, I. platycephalus, S. bramae, elongatum. acus (l.) Unionidae gen. sp E. sieboldi geometra Proteocephalus sp. greatest species diversity was observed in fish groups 2+, 3+, and 4+ (11, 14, 13 parasites, respectively). At ages 1+...

A total of six soil samples were collected around rhizosphere of citrus plants during 2010 from Melkassa Agricultural Research Center experimental station, Ethiopia. From these samples two most important ecto-plant parasitic nematodes of the genus Xiphinema were found and analysed. The genus Xiphinema is a large group of the phylum nematoda which constitutes more than 260 species. They are poly...

Upper Triassic deposits of the Leigh Creek Coal Measures in South Australia yield exquisitely preserved plant fossils a typical mid- to high-latitude Gondwanan flora. Here, we present detailed cuticular analysis ginkgoalean leaf Sphenobaiera insecta J.M. Anderson et H.M. nov. emend., which is characterized by an unlobed or once-lobed, elliptic oblanceolate lamina, abundant round fusiform resin ...
