Some species hyperaccumulate selenium (Se) upwards of 0.1% of dry weight. This study addressed whether Se hyperaccumulators also accumulate and tolerate more molybdenum (Mo). A field survey revealed on average 2-fold higher Mo levels in three hyperaccumulator Astragali compared to three nonaccumulator Astragali, which were not significantly different. Next, a controlled study was performed wher...

Hypotheses about chimpanzee social behavior, phylogeography, and evolution were evaluated by noninvasive genotyping of free-ranging individuals from 20 African sites. Degrees of relatedness among individuals in one community were inferred from allele-sharing at eight nuclear simple sequence repeat (SSR) loci. Males are related on the order of half-siblings, and homozygosity is significantly inc...

به­منظور بررسی و تحلیل روش­های اندازه­گیری تراکم، یک مکان مطالعاتی با چهار تکرار در منطقه فریدون شهر اصفهان با تیپ گیاهی غالبbromus tomentellus  - astragalus verus انتخاب گردید. در هر مکان­ مرتعی (محدوده 5000 مترمربعی با ابعاد 100×50 متر)، با شمارش کلیه پایه­های گونه­های گون زرد مقدار واقعی تراکم محاسبه شد. نمونه­برداری در هر مکان مرتعی به صورت تصادفی- سیستماتیک اجرا شد. در هر یک از تکرارها 5 ت...

Foamy viruses are frequently found in non-human primates and apes in captivity. However, data on simian foamy virus (SFV) infection in apes from the wild are limited. Necropsy specimens were collected from 14 West African chimpanzees (Pan troglodytes verus) from three communities in the Taï National Park, Côte d'Ivoire. PCR analysis revealed SFV-related int- and env-specific sequences in 12/14 ...

Astragalus mongholicus Bunge has long been used to treat cardiovascular disease in Chinese traditional medicine. However, its mechanisms are not fully understood. In this study, we explored potential mechanisms and protective effects of total flavonoids of Astragalus (TFA) on cardiovascular disease using in vitro experiments and diet-induced atherosclerotic rabbits. We identified six components...

because plant density is often measured by using plots and also in most cases are done by the method of estimation and counting the individuals, so one of the important cases that we have to decide on is the size and shape of plot. in this research, the density of astragalus verus that it's one of the dominate species in the area and has separate and recognizable individuals plant from eac...
