There is no published report regarding Iran's aquatic hyphomycetes. In an attempt to identify species of aquatic hyphomycetes in a river in central Iran (Zayande-Roud River), conidial frequency and distribution were determined by filtration. Water samples were collected monthly from two stations 55 km apart and filtered through millipore filters (5 um pore sizes). This was carried out for seven...
Ichthyozoonotic Mycobacterium spp. poses health risks both to fish and humans. In this study, the presence of ichthyozoonotic Mycobacterium spp. was investigated in red mullet (Mullus barbatus barbatus) and surmullet (Mullus surmuletus), widely caught species in the Mediterranean and the Aegean Sea. A total of 208 fish samples, provided from fishermen of Mersin province (Turkey) were studied. U...
Four different species of aphids belonging to the Aphididae family in four genera were collected and identified in Rape-seed fields in Sistan region during 2000-2001. Among them, Brevicoryne brassicae (Cabbage aphid) was the dominant species with an abundance of about 89% in area. The population fluctuation of Brevicoryne brassicae was studied simultaneously on fields in Sistan region (Zahak re...

Species were collected and identified. Overall, 82 identified plant species was belonging to 23 families and 61 genera. Asteraceae, Fabaceae, Lamiaceae and Poaceae families were the domi...
background & aim: chaharmahal va bakhtiari province contains several major floristic plant associations of central zagros mountains. kallar species were used for medicines nutrias in this area. however, these valuable species have been threatened and even become at risk of extinction due to habitat fragmentation and disturbance. therefore, the first step in protecting theses species is iden...
conclusions species identification of trichophyton is crucially important for epidemiological and phylogenetic purposes and for genotype delineation. rca based on its polymorphisms can be used to generate identification barcodes and as an alternative to dna sequencing; it is a very fast, specific, and economical tool for species identification. results of the 61 putative trichophyton clinical i...
For the purpose of sustainable exploitation of the fishery resources of Oni River, Ogun State, Nigeria, the fish biodiversity assessment was carried out. This was conducted by enumerating and identifying fish species composition, measuring the fish length, fish weight, assessing the fish abundance and biomass, determining the length-weight relationships and the length-frequency of the fishes. A...
