twenty four ecto- and endo- parasite species were found in different organs of eight na-tive and exotic fish species in zarivar lake situated in the far west of iran. overall, 1000 fish specimens belonging to the dactylogyridae, gyrodactylidae families the cyprinidae, poeciliidae and mastacembelidae families were examined during 2001 and 2002. of them, five protozoans, including trichodina pedi...

Because sequence information is now available for the 648bp barcode region of cytochrome c oxidase 1 (COI) from more than 400,000 animal species, this gene segment can be used to probe patterns of mitochondrial evolution. The present study examines levels of amino acid substitution and the frequency of indels in COI from 4177 species of arachnids, including representatives from all 16 orders an...

Multiplication and Squaring functions are widely used in many real time applications. They form an integral part in implementation of many Digital Signal Processing, Digital Image Processing and Multimedia algorithms. The size and power consumption of a DSP chip is influenced by the multiplication and squaring architectures that are used. The aim of this paper is to propose a novel fixed width,...

Insect diversity is believed to be used as a bio-indicator of spring quality. This study aimed at determining the insect around Mutis Timau Nature Reserve. The was conducted from June August 2019. Insects were caught by using yellow pan trap and hand sorting. insects determined based on Shannon-Wienner index (H'), species richness (R1), dominance (D), evenness (E). results showed that 16 belong...

Feed intake and feed efficiency of beef cattle are economically relevant traits. The study was conducted to identify QTL for feed intake and feed efficiency of beef cattle by using genotype information from 100 microsatellite markers and 355 SNP genotyped across 400 progeny of 20 Angus, Charolais, or Alberta Hybrid bulls. Traits analyzed include feedlot ADG, daily DMI, feed-to-gain ratio [F:G, ...

An updated checklist of mammalian richness is an important tool for biodiversity conservation and management protected areas. In this study, we present the wild mammals Shivapuri Nagarjun National Park (SNNP) in central mid-hill Nepal based on direct observation, field reports, key informant interviews, a literature review. A total 65 species belonging to eight orders 22 families were known occ...

Using data sourced from the SANBI MedList database, the most comprehensive inventory of ethnomedicinal plants for the Flora of southern Africa region, taxa were grouped by order. A least squares regression analysis was used to test the null hypothesis that the use of these plants by traditional healers is strictly random. The above approach, following a North American study by Moerman (1979), s...

the gamasiab river has one of the highest discharge in the western iran receiving wastewater of trout frames. the present study investigated effects of wastewater using bioassessment of benthic organisms. the benthos were sampled over four seasons using a surber sampler on four stations, upstream, on the farm outlet, 500 and 1000 m down the farm outlet. 5454 benthic fauna were identified that w...
