genetic diversity of six populations of bartail flathead (platycephalus indicus linnaeus, 1758) was investigated using amplified fragment length polymorphism (aflp). a total of 118 reproducible bands amplified with ten aflp primer combinations were obtained from 42 fishes that were collected from six different locations in the northern part of the persian gulf. the percentage of polymorphic ban...
تالاب حرا در استان هرمزگان با کارکردها و ارزش های متعدد، پرندگان نادر و آبزیان غیرمتعارف از جمله مهم ترین بوم سازگان های آبی در کشور محسوب می شود. در سال های اخیر به دلیل افزایش استقرار صنایع مختلف در سواحل و رشد و توسعه شهرهای ساحلی این بوم سازگان آبی و آبزیان موجود به دلیل تخلیه فاضلاب و آلاینده ها به آن به ویژه فلزات سنگین در معرض تهدید قرار گرفته اند. پژوهش حاضر به منظور تعیین غلظت فلزات سن...
جنس Helicotylenchus با حدود 250 گونة توصیف شده یکی از بزرگترین و رایجترین جنسهای راستة Tylenchida یا فوقبالاخانواده Tylenchomorpha بهشمار میآید. به منظور شناسایی گونههای این جنس، طی سالهای 1387-1389، بیش از 500 نمونة خاک و ریشة گیاهان از مناطق مختلف ایران جمعآوری گردید. پس از استخراج و انتقال نمونهها به گلسیرین، اسلایدهای میکروسکپی دائمی تهیه شده و با استفاده از میکروسکوپ نور...
The bovine Growth Hormone gene (bGH) is an attractive candidate gene for milk production in cattle. Single-strand conformation polymorphisms at bGH were identified and used to define haplotype configurations at this gene in the Israeli Holstein dairy cattle population (Bos taurus) and in the parent animals of the International Bovine Reference Family Panel (a collection of B. taurus and B. indi...
Differences in domestication and selection processes have contributed to considerable phenotypic and genotypic differences between Bos taurus and Bos indicus cattle breeds. Of particular interest in tropical and subtropical production environments are those genetic differences between subspecies that underlie the phenotypic extremes in tolerance and susceptibility to parasite infection. In gene...
Melilotus indicus (Linn.) All. is a small herb distributed throughout Pakistan and has a number of ethnomedicinal uses. It is also consumed as a vegetable. In the present work, we are reporting the alpha-amylase and urease inhibitory activities of methanolic extract of M. indicus and its sub-fractions in different solvents. Both the methanolic extract and its fractions in chloroform, ethyl acet...
We investigated the mitochondrial DNA (mtDNA) composition in one of the largest adult somatic mammalian clones (n = 20) reported so far. The healthy cloned cattle were derived from nuclear transfer of an identical nuclear genetic background (mural granulosa donor cells including surrounding cytoplasm) into enucleated oocytes with either Bos indicus or B. taurus mtDNA. Here we report the first c...
Adult flies of the genus Stomoxys Geoffroy, 1762 (Diptera: Muscidae), especially S. pullus Austen, 1909, S. uruma Shinonaga et Kano, 1966 and S. indicus Picard, 1908, are morphologically similar and sometimes difficult to distinguish when using external morphological characteristics. These species may act as vectors and/or potential vectors of many pathogens (virus, bacteria and protozoa). Thei...
Heavy metals are one of the most serious pollutants in the environment due to their toxicity, persistence and ability to concentrate along the food chain. Water bodies contaminated by heavy metals may lead to bioaccumulation in the food chain of an estuarine environment. Contamination of natural waters by heavy metals negatively affects aquatic biota and poses considerable environmental risks a...
A study of species diversity of Stomoxys spp. and diurnal variations of activity of the most abundant was performed during a one year period at a local dairy cattle farm in Wang Nam Khiao District, Nakhon Ratchasima Province, Thailand. Four species of stomoxyine flies were morphologically identified, including Stomoxys indicus Picard 1908, S. calcitrans (Linnaeus 1758), S. sitiens Rondani 1873 ...
