The major problems in transplanting the landscape trees are high level of mortality and low establishment rate of transplanted trees, especially in the first year. In order to achieve the best condition for successful transplanting of pine and plane trees in Isfahan landscape, the present study was carried out based on a completely randomized block design with four replicates and three treatmen...

Extended abstract 1- INTRODUCTION The contribution of crop cover to reducing runoff and erosion depends on the type, height, density and stage of plant growth. The literature review indicates that because of the different life forms, the effect of plants on the reduction of runoff and erosion are different at different growth stages [13]. However, no comprehensive studies have been conduc...

Under different climatic conditions of Iran, the evaluation of evapotranspiration (ETo) models sensitivity to meteorological parameters, prior to introducing the superior performance model, seems quite necessary. Using a 35-year (1971-2005) climatological observations in Hamedan, this study compares the sensitivity of different commonly used evapotranspiration models to different meteorological...

Gross primary productivity is one of the most important factors in the carbon cycle of terrestrial ecosystems. With global warming increase, the frequent drought events and the specific response of regional vegetation to these changes, it is essential to identify and quantify the relationships between climatic and GPP data in arid region. In this study, the responses of gross primary productivi...

based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...

"Technical Report" The quality of coastal water resources at the downstream of watersheds is decreasing mainly due to different anthropogenic activities. In this research, temporal variations of groundwater quality were investigated in a 25000 ha coastal area in Mazandaran province. Groundwater samples were taken from 37 observation wells in the region before (winter 2009), during (spring ...
