We analyse for the first time the genetic diversity within Ptyodactylus oudrii across the Maghreb. Two mitochondrial (12s rRNA and 16s rRNA) and two nuclear (C-mos and ACM4) markers are used. The results confirm the specific status of P. oudrii and show high levels of intraspecific variability, indicative of species complex. Lineages found are geographically concordant, and show similar pattern...

A large-type sexannulate leech species, Orobdella ibukifukuyamai sp. nov. , from Kii-Oshima Island, Japan, is described based on morphologic and molecular data. Phylogenetic analyses using nuclear 18S rRNA, 28S histone H3, mitochondrial cytochrome c oxidase subunit I, tRNA Cys Met 12S Val 16S Leu NADH dehydrogenase 1 markers showed that O. formed a clade with the okanoi Nakano, 2016 yamaneae oc...

Portions of two mitochondrial genes (12S and 16S ribosomal RNA) were sequenced to determine the phylogenetic relationships among the major clades of snakes. Thirty-six species, representing nearly all extant families, were examined and compared with sequences of a tuatara and three families of lizards. Snakes were found to constitute a monophyletic group (confidence probability [CP] = 96%), wit...

RNase MRP is a eukaryotic endoribonuclease involved in nucleolar and mitochondrial RNA processing events. RNase MRP is a ribonucleoprotein particle, which is structurally related to RNase P, an endoribonuclease involved in pre-tRNA processing. Most of the protein components of RNase MRP have been reported to be associated with RNase P as well. In this study we determined the association of thes...

Sampling of remote inland aquatic habitats in South Africa has constantly been yielding novel endemic freshwater crab species (Potamonautes MacLeay,1838). During the present study, we report on discovery and description two new baziya sp. nov., P. mariepskoppie nov.) from Afrotemperate forested mountain regions Eastern Cape Mpumalanga provinces Africa, respectively. Phylogenetic evidence derive...

Mitochondrial-derived peptides (MDP) are encoded by functional short open reading frames in the mitochondrial DNA (mtDNA). These include humanin, and the recently discovered mitochondrial open reading frame of the 12S rRNA-c (MOTS-c). Although more research is needed, we suggest that the m.1382A>C polymorphism located in the MOTS-c encoding mtDNA, which is specific for the Northeast Asian popul...
