Bromus sect. Triniusa is revised in Khorassan based on the new taxonomic concepts of Bromus danthoniae complex group and a remarkable herbarium material collected from Khorassan (Kopetdagh, northeastern Iran), as the main center of its diversity. Bromus turcomanicus, a narrow endemic species in central Kopetdagh hitherto known only from the type locality in southern Turkmenistan, is newly recor...

Background: Based on biochemical properties, Enterobacter cloacae represents a large complex of at least 13 variant species, subspecies, and genotypes that progressively identified as the most species causing hospital-acquired infections. The aim of this study was to determine the relevance between phylogenetically related strains within the E. cloacae complex and the frequency of urinary tract...

Objective: Ecosystems with mixed species compared to the ones with pure compositions provide a broader range of options in the fields of biodiversity, conservation, protection and restoration. Nearly all forest plantations are established as monocultures, but research has shown that there are potential advantages to be gained by using carefully designed species mixtures in place of monocultures...

so far, four species of hemidactylus have been reported in iran as follows: h. persicus, h. robustus, h. flaviviridis, h. romeshkanicus. in this study, 108 specimens belonging to these four species of hemidactylus were examined morphologically, using 19 metric and 6 meristic characters. multivariate analyses showed morphological differences among these three species with exception h. romeshkani...

five genera and ten species of the tribe aeliini still from the indo-pakistan region are keyed, compared to their closest allies and their geographical distribution given. a description of all the above genera and species of adria st?l and bonacialus distant has been given. these species, including two new species of adria, are described with special reference to their metathoracic scent gland ...

Morphological delimitation of Asian black truffles, including Tuber himalayense, T. indicum, T. sinense, T. pseudohimalayense, T. formosanum and T. pseudoexcavatum, has remained problematic and even phylogenetic analyses have been controversial. In this study, we combined five years of field investigation in China with morphological study and DNA sequences analyses (ITS, LSU and β-tubulin) of 1...
