species diversity is an index for sustainability of rangeland ecosystems. we studied the effect of environmental factors (soil properties and aspects) on plant species diversity in zagros mountainous rangelands (vegetation type: festuca ovina-astragalus parrowianus) in the west of hamadan in march–july 2009. for this purpose, four aspects were defined in the study area. vegetation types were st...

The aim of our study was to describe and compare nutritional status and food related behaviours in rural pregnant women of Li ethnicity as they had been divided into mountainous and costal groups by residential area. One hundred and ninety-six randomly selected healthy rural pregnant women of Li ethnicity for the mountainous group (MG), and eighty-two for the coastal group (CG) were recruited. ...

One new species of the genus Phradis, P. peruvianus sp. n., from the mountainous part of Peruvian Amazonia, is described and illustrated. This is the first record of the genus from South America and the

In recent years, there has been growing interest in the association between the residential environment and health. The association between residential environment (i.e., geographic elevation) and bone status is unknown. Furthermore, these associations could differ by exercise habits due to the chronically greater daily activity caused by steep slopes in mountainous areas. The aim of this study...

Consistent time series rainfall datasets are important in performing climate trend analyses and agro-hydrological modeling. However, temporally consistent ground-based long-term observed data usually lacking for such analyses, especially mountainous developing countries. In the absence of data, satellite-derived products, as Climate Hazard Infrared Precipitations with Stations (CHIRPS) Global P...

Range-Doppler model is a transformation that relates ground and Single-Look Complex SAR image spaces by knowing the instantaneous position velocity of sensor in its trajectory. Its velocities are determined with help vectorial functions, which their precisions directly influence accuracy range-Doppler model. Ephemeris data one sources used for estimation temporal functions. Some reasons can cau...

It has been known that the chicken's resistance to disease was affected by chicken's genetic background. And RLR-mediated antiviral pathway plays an important role in detection of viral RNA. However, little is known about the interaction of genetic background with RLR-mediated antiviral pathway in chicken against MDV infection. In this study, we adopted economic line-AA broilers and native Erla...

Ascorbic acid in aqueous humor of the eye has a role as an antioxidant in delaying cataract formation. In a cross-sectional comparative study, ascorbic acid levels from aqueous humor and venous blood obtained from patients with cataracts in mountainous regions (1,300-2,000 meters) and subtropical lowlands (<100 meters) of Nepal were measured spectrophotometrically with the objective of comparin...
