Arasbaran is one of the most important protected regions in Iran located in NW of the country and east of E Azarbaijan Province. Several reports have been published on the mycobiota of this region however there is only few records about rust fungi of Arasbaran. Our research on rust fungi of Arasbaran region get started since 2006. During this study, several rust taxa collected and identified fr...

Due to the importance of the Arasbaran forest (E. Azarbaijan, N.W. Iran) as a biosphere preserve and having a rich flora and fauna, macrofungi flora of Arasbaran region, were studied from 2003. This is the first in a series of publications on floristic studies of macrofungi of Arasbaran forests. In this paper, species of the genus Cortinarius, subgenus Myxacium are studied.The genus Cortinarius...

Ecological Role of Altitude on Quantitative Characteristics Caucasian Oak (Quercus macranthera Fisch. & C.A.Mey. ex Hohen.) Stands in Arasbaran Forest

Cornelian cherry (Cornus mas L.), considered as the ancestor of cultivated trees in Arasbaran region, is a medicinally and economically plant species. However, little is known about genetic diversity, breeding programs, and population structure of this species in mentioned region. Keeping this in view, the main objectives of present study were to analysis the genetic diversity, phyloge...

Ecological Relationships of Slope and Elevation with Rowan (Sorbus aucuparia L.) in Arasbaran Forests

forest roads are basic infrastructures for management of forested areas. sustainable management of roads depends on regular and timely forest road maintenance. road inventory is as an important tool to recognize the needs of roads and do corresponding correction operations. gis can be a powerful tool for acquirement, analysis and management of data in road management. the purpose of this study ...

This article proposes a new formulation for the maximum leaf spanning tree problem (MLSTP) using network flow concepts to ensure graph connectivity of problem’s solutions. Since MLSTP is NP hard, genetic algorithm (MGA) also developed solve large-scale instances. The proposed optimally solved 37 out 41 instances existing benchmarks, comparable with results available formulations in literature. ...

this research has been carried out with the aim of the determination of the land-use changes of the forests in the protected area of arasbaran. the determination of the changing points and the factors influencing these changes by the use of gis and remote sensing are the main aims of this research. accordingly, the satellite pictures pertaining to the years 1987 and 2005 along with other necess...
