Based on the importance and role of species diversity and richness as ameasurement of the health of an ecosystem; studying of their components can lead toevaluate the health condition of rangeland. This research was carried out in a part ofhighland mountainous rangeland of Mount Alborz Range in Iran. Diversity and richnesswere assessed as an ecosystem health indicator. The study area was locate...

Due to the decreasing trend of rangelands, many native species are vulnerable and even at risk of extinction. Therefore, seed preservation and propagation of native species of rangelands and recognition of the characteristics of grazing, drought tolerance and their production potential are very beneficial. In this study, the five species of Festuca ovina, Festuca rubra, Br...

four genera and five species of idolothripinae are recorded in iran: allothrips hood, compsothrips reuter and pseudocryptothrips priesner each with one species, and megathrips targioni-tozzetti with 2 species. in this paper, the genus nesothrips kirkaldy, with one species n. brevicollis (bagnall) collected on grasses in marivan, kurdistan province, is recorded in iran for the first time. a key ...

     Forage production of rangelands differs during different times of grazing season and in the same month of different years. In range management projects, grazing capacity calculated once during the grazing season, which coincides with the maximum production of rangeland species. This may cause more livestock entry into the rangeland during the grazing season, leading to more degradation. Th...

three species of tuberculina viz. t. persicina, t. sbrozzii and t. maxima are newly reported from iran. information about distribution and host range of species is provided. each species is re-described and illustrated by photomicrographs. a key for reported taxa is also provided.
