We here report the draft genome sequences of 8 Yersinia pestis subsp. microtus bv. caucasica strains isolated from the East Caucasian (previous name, Dagestan) mountain focus (no. 39), representing the most ancient branch of the 0.PE2 phylogroup circulating in populations of common voles (Microtus arvalis).
The Adriatic Sea and drainage system (or region) is characterized by high levels of species richness. This especially applies to endemic fishes, as exemplified the sand gobies. However, diversity this group probably still underestimated. Several keys for gobiid identification, notably region, have been proposed on basis morphological characters, but difficulties persist in identification. Molec...
جهت بررسی رابطه طول و وزن گاو ماهی قفقازی تعداد 464 قطعه ماهی به وسیله تور پره از بهمن ماه 1390 تا دی ماه 1391 صید گردید. نسبت جنسی نر به ماده در جمعیت مورد مطالعه 1:1/06 بود که اختلاف معنی داری بین نسبت جنسی نر و ماده در جمعیت فوق وجود نداشت (x2 = 0.422, p > 0.05). بیشینه طول کل و وزن ماده ها 41/78 میلی متر و 1/08 گرم و برای نرها 46/12 میلی متر و 1/26 گرم ثبت گردید. رابطه طول و وزن در ماده ها ...
جهت مطالعه ویژگیهای تولیدمثلی گونه گاوماهی قفقازی (K. caucasica) تعداد 149 نمونه از خلیج گرگان و تعداد 192 نمونه از تالاب گمیشان بهصورت ماهانه از بهمنماه 92 تا اردیبهشتماه 93 با استفاده از تور پره صید شد. در این تحقیق فاکتورهای مرتبط با تولید مثل از قبیل نسبت جنسی، شاخص نمو گنادی، هم آوری مطلق، هم آوری نسبی محاسبه شد. نسبت جنسی ماهیان مورد مطالعه در خلیج گرگان 01:1/1 و در تالاب گمیشان 26:1 ...
As of now, within the lace bug family Tingidae (Cimicomorpha), only 1.5% of the species described have been cytogenetically studied. In this paper, male karyotypes of Stephanitis caucasica, Stephanitis pyri, Physatocheila confinis, Lasiacantha capucina, Dictyla rotundata and Dictyla echii were studied using FISH mapping with an 18S rDNA marker. The results show variability: the major rDNA sites...
Butterfly community and single species based approaches were taken to establish conservation priorities within a nature reserve in Central Spain. In this study, patch type (sclerophyllous, halophilous, or disturbed), potential herbaceous nectar availability, potential woody plant nectar availability, total nectar availability, and two approximations to plant diversity (herbaceous and woody plan...
afforestation of contaminated areas is considered as a possible strategy for reduction of contaminations. in the present study, the effects of lead (pb) and cadmium (cd) were investigated on chlorophyll fluorescence parameters (fv/fm, fo, and fm), photosynthetic pigments (chlorophyll a, b, and total chlorophyll), and proline in one-year-old seedlings of celtis caucasica and robinia pseudoacacia...
The gene coding for beetle luciferase, the enzyme responsible for bioluminescence in over two thousand coleopteran species has, to date, only been characterized from one Palearctic species of Lampyridae. Here we report the characterization of the luciferase gene from a female beetle of an Iranian lampyrid species, Nyctophila cf. caucasica (Coleoptera:Lampyridae). The luciferase gene was compose...
