Although a mitochondrial DNA barcode has been shown to be of great utility for species identification and discovery in an increasing number of diverse taxa, caution has been urged with its application to one of the most taxonomically diverse vertebrate groups - the amphibians. Here, we test three of the perceived shortcomings of a CO1 DNA barcode's utility with a group of Holarctic amphibians: ...

In this study, we sequenced fragments of cytochrome oxidase subunit 1 (CO1), internal transcribed spacer 1 (ITS1), and internal transcribed spacer 2 (ITS2) genes from 150 specimens belonging to 16 species of the ant genus Formica from China. Odontoponera transversa from Ponerinae and Polyergus samurai from Formicinae were added as distant relative and close relative outgroups, respectively. Nei...

We study a self-dual N = 1 super vertex operator algebra, denoted A, and prove that the full symmetry group is Conway’s largest sporadic simple group Co1. We verify a uniqueness result for A which is analogous to that conjectured to characterize the Moonshine vertex operator algebra V . The action of Co1 on A is sufficiently transparent that one can derive explicit expressions for the McKay-Tho...

The synthesis and characterization of mononuclear Co(II) complex based on 3,5-dimethyl-4-amino-1H-pyrazole are reported. IR UV/Vis spectroscopy the described. synthesis, results IR, NMR elemental analysis also X-ray [Co(C5H9N3)2Cl2] reveals that cobalt atom has a tetrahedral coordination environment formed by two nitrogen atoms belonging to ligands [Co1–N1 = 2.005(3) Co1–N5 2.006(3)Å] chlorine ...

To expand our knowledge of electronic structures and magnetic properties for ferromagnetic shape memory Co-Ni-Al alloys, which undergo a thermoelastic martensitic transformation from a B2 to an L10 structure, we have performed first-principles band calculations for the composition of Co:Ni:Al = 1:1:1, i.e., (Co1=3Ni2=3)(Co1=3Al2=3) and (Ni1=3Co2=3)(Ni1=3Al2=3). Their electronic structures have ...

Purpose We investigate the function of the V83I polymorphism (m.6150G>A, rs879053914) in the mitochondrial cytochrome c oxidase subunit 1 (MT-CO1) gene and its role in African American (AA) primary open-angle glaucoma (POAG). Methods This study used Sanger sequencing (1339 cases, 850 controls), phenotypic characterization of Primary Open-Angle African American Glaucoma Genetics study (POAAGG)...

ساختار ژنتیکی جمعیت گرگ در سطح دنیا تحت تأثیر وقوع تجزیه شدن جمعیت و نوسان‌های جمعیتی در طی دوره‌های یخبندان قرار گرفته است. با توجه به پراکندگی گسترده گرگ در ایران و نیاز به شناسایی دقیق گونه‌ها در برنامه‌های حفاطتی، در این مطالعه جایگاه و روابط زیرگونه‌های احتمالی گرگ در ایران Canis lupus pallipes، Canis lupus cubanensis و Canis lupus lupus با سایر زیرگونه‌...

چکیده: جنس calomyscus مدتها با گونه c. bailwardi به عنوان یک جنس تک گونه در نظر گرفته می شد. ولی براساس مطالعات اخیر، هشت گونه کروموزومی معرفی شده است: c. bailwardi (zagros mountains calomyscus), c. baluchi (pakistan calomyscus), c. elburzen-sis (goodwin, s calomyscus), c. grandis (noble calomyscus), c. hotsoni (hotson, s calomys-cus), c. mystax (great balkhan calomyscus), c. tsolovi (syrian ...

Species inventories are essential for documenting global diversity and generating necessary material for taxonomic study and conservation planning. However, for inventories to be immediately relevant, the taxonomic process must reduce the time to describe and identify specimens. To address these concerns for the inventory of arthropods across the Malagasy region, we present here a collaborative...
