I'm going to argue here that majordifficulty in the way of consisting ...
For the identification of phylogenetic characteristics of honeybee populations, sampling was conducted from 31 provinces of Iran in spring and summer 2016. Phylogenetic characteristics were evaluated based on mitochondrial ND2 gene. The intergenic regions between ND2 and COI genes were compared in different populations of honeybees. After sequencing and alignment of the genes, the relationships...
abstract during a survey for detection of pvs in potato fields in northern khorasan province, some tubers from the plants which have been already marked and showing mosaic, rugosity, undulation on leaf margins, little leaf and slightly vein deepening, were collected in bodjunrd region, also, some tubers from potato fields of mashhad, chenaran, ghoochan, faruj and shirvan regions were randomly c...
Global temperatures have increased in the past 100 years by an average of 0.74°C (IPCC, 2013), with minimum temperatures increasing faster than maximum temperatures and winter temperatures increasing faster than summer temperatures (IPCC, 2013). Total annual rainfall tends to increase at the higher latitudes and near the equator, while rainfall in the sub-tropics is likely to decline and become...
background: intestinal parasitic infection is one of the major public health problems in developing countries. children are more vulnerable to these infections. in addition, the prevalence of infection is different among various communities; hence, there is a need for the periodical prevalence evaluation. this study was performed to define the prevalence of intestinal parasitic infection among ...
The vegetation covering of a region has a direct correlation with climate. So if data is available for vegetation cover, the second variable (climate) can be easily predicted and in reverse. The dominant species in a region are indication of its climatic conditions and vice versa. Accordingly, this is of significance in the science of historical botany. Fortunately, from the first millennium A...

Abstract. Rangeland vegetation dynamics encompass all processes of changes in vegetation composition and structure over time. Investigating the rangeland ecosystem dynamics makes it possible to determine the effects of climatic and management conditions on qualitative and quantitative changes of the vegetation in a specific period of time. Accordingly, data collection and measurements for evalu...
