abstract rodent have global spread and include the largest order of mammals that their broad range of adaptation is extensive. so far don’t perform a study on rodent fauna of ferdows county. therefore, the aim of this study is to identify this part of the vertebrates in this area. in this regard in order to identification and biosystematics survey of rodent fauna from winter 2014 to june 2014 i...

One of the most common problems in breeding of ostriches in captivity is the control of parasitic diseases. This work presents keys for the identification of adult nematodes and infective larvae by morphologic and morphometric characteristics. These keys will allow the scientific community to identify the species that infect the ostriches either based on the characteristics of the posterior end...

The systematic study of feather microstructure supports species identification, which is important in cases illegally traded birds and bird-aircraft strikes. Our focused on morphometric, macro- micro-characters feathers Common Myna Acridotheres tristis from India. Among macro-characters, silver-colored filoplume with pale black pigmentation the barbs are specific for A. tristis. Morphometric me...

The echolocation ability of several dolphin species is well documented, but little is known about hearing characteristics of most marine mammals. This paper describes the major features of the peripheral auditory system in both large and small whales and presents a three-dimensional morphometric analysis of the inner ear in 12 species. Correlation analyses of inner ear morphometry vs. hearing c...

   Stability of bacterial flora in fish intestine is very important, because the intestine is an important organ for outbreak of microbial infections and other fish diseases especially when the fish have not been vaccinated. The aim of this study was to determine the bacterial flora of intestine in sturgeon juvenile in earthen ponds. The results can be applied to prevent the diseases occurren...

Nine hundred eighty species belonging to 182 genera of 15 subfamilies of the family Dolichopodidae were investigated to study antennal morphology. Length measurements of scape, pedicel, postpedicel and arista and height measurements of postpedicel bases were performed, and 4 ratios were selected. Use of morphometric characteristics of Dolichopodidae antennae allows meaningful distinctions betwe...

BACKGROUND Advanced brain MR techniques are useful tools for differentiating Progressive Supranuclear Palsy from Parkinson's disease, although time-consuming and unlikely to be used all together in routine clinical work. We aimed to compare the diagnostic accuracy of quantitative morphometric, volumetric and DTI metrics for differentiating Progressive Supranuclear Palsy-Richardson's Syndrome fr...

The tumor microcirculation is characterized by an abnormal vascular network with dilated, tortuous and saccular vessels. Therefore, imaging the tumor vasculature and determining its morphometric characteristics represent a critical goal for optimizing the cancer treatment that targets the blood vessels (i.e. antiangiogenesis therapy). The aim of this study was to evaluate new vascular morphomet...

during 2012-2013 in a funistic survey of snails, several species of snails were collected and identified; both from orchards, farms and the weeds. in total, 18 species belonging to 17 genera out of 10 families are identified based on morphometric characteristics including (shape and size of operculum, aperture, dextral or sinistral of shell, pneumostome, keel, radula, renal ridge and reproducti...

To study the intraspecific diversity of Caspian Asp, Leuciscus aspius in South Sea region, Iran, we collected 2016–2017 a total 101 specimens from Aras River and Astara, Anzali, Kiashahr Langeroud shores, analysed 41 morphometric nine meristic characteristics with multivariate statistical methods. Significant differences were found between these populations 27 traits. A Principal Component Anal...
