The tropical anguillid eel, Anguilla bicolor McCelland, 1844, includes two subspecies, 1844 and pacifica Schmidt, 1928, is distributed across the Indo-Pacific region. Although A. widely recognized as an important fish resource in region, few studies have been conducted on its genetic variation population structure. DNA barcoding of specimens collected region was carried out this study using mit...

With the increasing number of cryptic species discovered in major branches subfamily Steganinae, accurate identification is becoming challenging. Possible evolutionary stasis often gives rise to formation morphological conservatism and species, as case for members Stegana (subgen. Orthostegana). In this study, boundaries all Asian Orthostegana were accessed based on two mitochondrial genes [cyt...

Sequences of the complete mitochondrial cytochrome oxidase subunit I gene were used to identify Trichiurus species and examine their population genetic structure demographic history along coast China. Three found. japonicus lives in colder waters continental shelves China Seas, while nanhaiensis warmer slopes South Sea, brevis shallow Sea. The migrations these mainly associated with feeding spa...

background: adult worms of orientobilharzia turkestanicum live in the portal veins, or intestinal veins of cattle, sheep, goat and many other mammals caus-ing orientobilharziasis. orientobilharziasis causes significant economic losses to livestock industry of iran. however, there is limited information about genotypes of o. turkestanicum in iran. methods: in this study, 30 isolates of o. turkes...

The ATP-dependent PIM1 protease, a Lon-like protease localized in the mitochondrial matrix, is required for mitochondrial genome integrity in yeast. Cells lacking PIM1 accumulate lesions in the mitochondrial DNA (mtDNA) and therefore lose respiratory competence. The identification of a multicopy suppressor, which stabilizes mtDNA in the absence of PIM1, enabled us to characterize novel function...

Attempts to rationalize the kinetics of cytochrome c oxidation catalyzed by solubilized mitochondrial cytochrome c oxidase (ferrocytochrome c:oxygen oxidoreductase, EC 1.9.3.1) have been based on assumptions of productive complex formation (Michaelis-Menten approach). However, the range of substrate concentrations used has not, in general, been sufficient to establish a general rate equation. D...

A new species of the monotypic genus Weygoldtia Miranda, Giupponi, Prendini & Scharff, 2018 was described from Con Son island, southern Vietnam, namely condao sp. nov. The is clearly distinguished its congener davidovi (Fage, 1946) by having more articles in tibia and tarsus leg I. fragment cytochrome c oxidase subunit I (COI) gene also provided for species. K2P genetic distance COI between...

To study the phylogenetic relationships of Indian termites (Insecta: Isoptera), mitochondrial DNA sequences of 334 bp of Cytochrome Oxidase subunit I gene of nine species were subjected to MEGA 5.2. Phylogenetic trees were constructed using Neighbor-Joining and Maximum Likelihood methods. The results revealed the phylogenetic status of Indian termites with other species from different geographi...

Two new species of Mouse Spiders, genus Missulena, from the Pilbara region in Western Australia are described based on morphological features of males. Missulena faulderi sp. nov. and Missulena langlandsi sp. nov. are currently known from a small area in the southern Pilbara only. Mitochondrial cytochrome c oxidase subunit I (COI) sequence divergence failed in clearly delimiting species in Miss...

A new species of brown frog Rana luanchuanensis Zhao & Yuan, sp. n. is described from Luanchuan County, western Henan, central China. The mitochondrial genealogy suggests that the new species is the sister taxon to the clade including R. amurensis and R. coreana, and is separated by uncorrected pairwise distances more than 12.5%. Morphologically, this new species differs from its congeners by a...
