BACKGROUND Ticks are the main vectors for transmission of different pathogens to human and animals. This survey was performed to find out distribution of ticks, which infested the domestic ruminants in Yazd Province, central Iran during year 2008-2009. METHODS A total number of 30 villages from both mountainous (20%) and plateau (80%) regions of the province were selected randomly. Ticks were...

introductionit is expected that projected changes in the frequency and severity of extreme climate events, such as increased frequency of heat stress, droughts and flooding will have significant consequences on water resources. increasing pressure on water resources due to climatic and anthropogenic changes as well as increasing competition among users is recognized challenges worldwide. global...

the measurement of chlorophyll content of leaf is as an appropriate criterion in breeding programs to increase the rate of leaf photosynthesis. in order to study the relationship between chlorophyll content and seed yield under saline conditions, 41 wheat genotypes were evaluated in two conditions (normal and salinity stress) at the research field of the national salinity research center (nsrc)...

this research was conducted to investigate the relationships between soil(organic matter, potassium, phosphorous, sodium, fine gravel, soil texture, ec, lime,gypsum, nitrogen) and environmental (elevation, slope) factors with distribution ofvegetation types in rangelands of sabzdasht, located in bafgh, yazd province at 2012. forthis purpose, four vegetation types were selected as follows: artem...

The appropriate management of crop conditions can reduce the salt damage suffered by ornamental species and produce high-quality plants even when saline irrigation water is used. The aim of this study was to determine whether the pot-in-pot (PIP) cultivation system can improve the saline irrigation tolerance of Euonymus japonicus compared with aboveground potting (AGP) in terms of growth and de...

a breeding hexaploid salt tolerant wheat line (ms-81-14) was produced from crossing of an iranian salt tolerant wheat line (1-66-22) with inia cultivar (from cimmyt) at karaj research station in 1991-92 cropping season. the f1 plants were grown at karaj in 1992-93 cropping season, furthermore f2-f6 populations were evaluated under salinity stress conditions (ecsoil&water; = 8-12 ds/m) in isfaha...

in recent years, the groundwater resources in guilan province have played an important role in irrigating paddy fields. the goal of this study was to evaluate temporal and spatial variations of groundwater quality in a 4-year period using ordinal kriging. water samples for this study were collected from 130 wells across guilan province, in september and march from 2003 to 2006.  maps of ec and ...
