Abstract: The aim of this study is investigating the changes of macro elements in soil and vegetation based on the different life form with changes in elevation. For this purpose, soil and vegetation sampling was performed in 13 places in the elevation gradient of 300 to 3300 meters in 2016. In each site were placed three transects of 100 meters with 50 meters distance from each other and along...

Mapping the spatial distribution of soil taxonomic classes is important for useful and effective use of soil and management decisions. Digital soil mapping (DSM) may have advantages over conventional soil mapping approaches as it may better capture observed spatial variability and reduce the need to aggregate soil types. A key component of any DSM activity is the method used to define the relat...

This article presents an analysis of plant species richness and diversity, concerning some climatic variables along a 1500-m elevation gradient on the Binalood Mountain in Heydari Wildlife Refuge (HWR), northeastern Iran.  Two hundred and thirteen nested-sampling quadrats were established and the abundance of the plants was recorded. Vegetation sampling was carried out from 2014 till 2016, foll...

Biodiversity is one of the important aspects of natursal systems which supports ecosystem functions. Therefore, the preservation of biodiversity is necessary for human well-being. The curreny study aimed to investigate changes of alpha and beta diversity and its components along the elevation gradient of five classes and to evaluate the effects of physical and chemical characteristics of soil o...
