Enzymatic diversity in the haloactinomycetes isolated from rhizosphere of plants saline soils at periphery Dasht-e-Kavir desert
Potential Analysis of Kavir & Desert Region and Makran Coasts In Order To Obtain Energy From the Sun Using Fuzzy Logic AHP
in desert areas high temperature and low precipitation limit growth and development of plants. under this circumstances wind becomes the most important erosion and transportation factor in these areas. there are four great sand masses in the central part of dasht-e-kavir namely rig-e-jen, rig-e-sargardan (shotori or halvan), rig-e-kharturan, and rig-e- chah-e-jam. these great sandy masses show ...
The remains of the natural and human activities in some parts of the earth register as geopark. Actually, geopark is one or more geological phenomenon which is important from ecology, history, culture and archeological view. The aim of the geotourism description in an area and creating a geopark is trying to keep the earth's inheritance and locality the economic of the area. Iran with an old hi...
Saline rhizospheric areas are untouched environments for isolating actinomycetes with the potential of valuable salt tolerant enzyme production. In this study, we isolated and evaluated a total number of of 26 actinomycete strains from plant rhizosphere of the periphery of Dasht-e-Kavir desert. Isolated actinomycetes produced different enzymes. Among them 50, 46, 39, 27, 10 and 7 % of the isola...
Abstract Integrated geophysical mapping benefits from visualizing multi-source datasets including gravity and satellite altimetry data using 2D 3D techniques. Applying scripting cartographic approach by R language GMT supported traditional in QGIS is presented this paper with a case study of Iranian geomorphology special focus on Zagros Fold-and-Thrust Belt, unique landform the country affected...
The molecular status of nine species of the genus Alburnoides from different river drainages in Iran and additionally by seven species from Europe was assessed. mtDNA COI gene sequences from freshly collected specimens and available NCBI data revealed four major phylogenetic lineages. Based on the results, a distinct taxon from the Cheshmeh Ali (Ali Spring), a Damghan River tributary in the end...
abstract a great part of iran’s area, especially yazd province is formed as deserted areas. kavir siahkooh is one of the most important desert areas of province. the researches show that the arid areas have an ideal condition for remote sensing and it can consider and show the plant coverage of the area .the aim of this study is to evaluate kavir siahkooh plant coverage and it’s comprise with t...
kavir national park is an example of dry and desert ecosystem that is consisted of vast plains and numerous highlands. wild sheep is one of the iconic bovid in this area. understanding their habitat requirements and similarities is essential for their successful population management. we used ecological niche factor analysis approach to develop habitat suitability models for wild sheep in kavir...
the result of wind dynamic (capacity and potential) is transport of soil or sediment particles and subsequent formative desert landforms based on the severity of erosion or sedimentation. the khartouran region, because of its geology, geomorphology and climatology conditions is a special place in the arid region on the closed basin of dasht-e-kavir. it is evident that the ecosystem balance of t...
