in recent years, shallow bark canker of walnut (juglandis regia l.) trees has become fairly widespread in iran. to determine the distribution of the disease in golestan, mazandaran and gilan provinces, from early summer to mid-fall seasons of 2004, more than one hundred bark samples were collected from walnut trees showing symptoms of shallow bark canker. sixty strains of bacteria were isolated...

Brown spot caused by Bipolaris oryzae is an important rice disease in Southern coast of Caspian Sea, the major rice growing region in Iran. A total of 45 Trichoderma isolates were obtained from rice paddy fields in Golestan and Mazandaran provinces which belonged to Trichoderma harzianum, T. virens and T. atroviride species. Initially, they were screened against B. oryzae by antagonism tests in...

background: cancer is a major public health problem in the world. in iran especially after a transition to a dynamic and urban community, the pattern of cancer has changed significantly. an important change occurred regarding the incidence of cancer at the southern shores of the caspian sea, including gilan, mazandaran and golestan province. this study was designed it investigate the epidemiolo...

Anthropogenic environmental changes are hypothesized as main reasons for animal species population declines. Heavy metals contamination is one of the worst threats to animals among human-caused threats. As most of the heavy metals bioaccumulate in organisms, analyzing concentrations of heavy metals in long living animals, such as turtles, would be very useful for biomonitoring of environmental ...

in order to investigate biodiversity of industrial crop in iran, an investigation was made based on the statistical data available on acreage and production of this crop in the country. cultivated area of industrial crop from 29 provinces were analyzed and shannon biodiversity index was calculated. the highest biodiversity index compare to the total crop species was observed in golestan, semnan...

Genetic diversity as an important marker of the ecological status of aquatic ecosystems is considered a unique and powerful tool to evaluate biological communities. In order to evaluate the genetic diversity among golden mullet species (Liza aurata) in the southeast and southwest coasts of the Caspian Sea by D-Loop gene sequencing, a total of 23 fin specimens of golden mullet were collected fro...

Variations in fruits morphology of Tilia spp. were studied along longitudinal and altitudinal range. Ten populations of Tilia spp.from Golestan, Mazandaran and Gilan Provinces (N. Iran) were selected. After biometrical measurements and Scanning Electron Microscopic (SEM), Cluster Analysis divided the population into seven groups. Discriminat Analysis showed that among all traits studied, size o...
