The genetic variability of the COI gene was studied in the common octopus, Octopus vulgaris Cuvier, 1797. A total of 222 individuals from 7 sampling sites were analysed with the aim of elucidating patterns of genetic variation along the coasts of Sardinia (Western Mediterranean). A total of 17 different haplotypes were identified with four principal haplotypes recorded in all locations. The pai...

Mordellochroa humerosa (Rosenhauer, 1847) is reported from Slovakia for the first time based on 13 specimens collected in 2017–2020 two localities. The known distribution of species and collection circumstances are discussed, four mtDNA sequences COI gene fragment submitted to GenBank BOLD. Photographs habitus drawings diagnostic characters provided M. . 

In South Africa, the family Heliozelidae in order Lepidoptera is restricted to four known species. The grapevine leaf miner, Holocacista capensis, feeds between epidermal layers of a leaf, predominantly along margin. A final instar larva will descend from blotch mine/gallery attach its cocoon casing (constructed mined gallery) any object below infested leaf. Five monophyletic clades and polyphy...

This study reports on the molecular identification of fish species from processed products which had a priori been classified as belonging to 5 important species in Iran for human consumption. DNA barcoding using direct sequencing of an approximately 650bp of mitochondrial Cytochrome oxidase subunit I (COI) gene revealed incorrect labeling of Narrow-barred Spanish mackerel samples. High occurre...

Analyses of the Trypanosoma equiperdum (ATCC 30019) maxicircle reveals deletions, duplications and rearrangement compared to T. brucei. The genes for 9S rRNA and 12 proteins are absent. The 12S rRNA and cytochrome oxidase subunit I (COI) genes lack their 3' ends and are adjacent indicating deletion of intervening genes. The remaining two NADH dehydrogenase subunit genes (ND4 and ND5), the ribos...

IMPORTANCE It is unclear how medical journals address authors' financial and non-financial conflict of interest (COI). OBJECTIVE To assess the policies of clinical journals for disclosure of financial and non-financial COI. METHODS Cross sectional study that included both review of public documents as well as a simulation of a manuscript submission for the National Library of Medicine's "co...

We have conducted the first phylogenetic study to our knowledge of Zoanthus in the northern hemisphere by sequencing and analysing the mitochondrial cytochrome oxidase subunit 1 (COI) gene. Various unidentified Zoanthus specimens and samples of what have been assumed to be four discrete species (Z. pacificus, Z. sansibaricus, Z. gnophodes, Z. erythrochloros) were collected from four field sites...
