Due to the presence of a large number of parameters involved and the existing uncertainties, decision making in this fi...
Background and Aim: Biological vectors of malaria are only anopheles mosquitoes. Since the vector control without identifying them and understanding their biology is not possible, the present study was designed to identify anopheles fauna in different areas of Qayenat city and their internal or external shelters. Materials and Methods: Larvae, pupae, and adults of anopheles mosquitoes we...
Although Iran's Ghaen Plain provides saffron to much of the world, no regional groundwater quality (GQ) assessment has yet been undertaken. Given the region's potential for saltwater intrusion and heavy metal contamination, it is important to assess the GQ and determine its main probable source of pollution (MPSP). Such knowledge would allow for informed mitigation or elimination of the potenti...
Saffron is an important crop in social and economical aspects in Khorassan Province (Northeast of Iran). In this research we tried to evaluate trends of saffron yield in recent years and to study the relationship between saffron yield and the climate change. A regression analysis was used to predict saffron yield based on 20 years of yield data in Birjand, Ghaen and Ferdows cities. Climatologic...
