the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
Background: Changing the climatic pattern can lead to major changes in the geographical distribution of infectious diseases. The aim of this study was to investigate the effect of climate change on the favorable bio-climatological zone for leishmaniasis sand-fly living which is a vector of Leishmania in Iran. Materials and Methods: Data of the climatic factors affecting the biology of sandflies...
Climate change due to increasing the concentration of greenhouse gases (especially CO2) in the atmosphere causes changes in the rainfall regime, runoff rate, wind speed and solar radiation of atmosphere. In the present research, the maximum and minimum temperature parameters were simulated during the base period of 1979-2088 and two future periods of 1979-2070 and 2070-2090 using daily ...
Changes in the geographical distribution of plants are one of the major impacts of the climate change. This study was aimed to predict the potential changes in the distribution of Artemisia aucheri Boiss in Isfahan rangelands. Therefore, six bioclimatic variables and two physiographic variables were used under the Generalized Linear Model (GLM), Flexible Denotative Analysis (FDA), Surface Range...
BACKGROUND Although some studies have indicated that climate changes can affect Pinus koraiensis mixed forest, the responses of composition and structure of Pinus koraiensis mixed forests to climatic changes are unknown and the key climatic factors controlling the composition and structure of Pinus koraiensis mixed forest are uncertain. METHODOLOGY/PRINCIPAL FINDINGS Field survey was conducte...
Climate change and drought have negative consequences, including the spread of deserts. In this research, the impact of climate change on some climatic variables (temperature and precipitation) of Firoozkooh and Garmsar synoptic stations in the period 2030-2011 and 2065-2046 using LARS-WG model under scenario A2, B2 and A1B and finally desertification hazard and risk using ESAs model in Hablehr...
Relatively, few species have been able to colonize extremely cold alpine environments. We investigate the role played by the cushion life form in the evolution of climatic niches in the plant genus Androsace s.l., which spreads across the mountain ranges of the Northern Hemisphere. Using robust methods that account for phylogenetic uncertainty, intraspecific variability of climatic requirements...
Today climate change is one of the most important human concerns This fact affected human life in different ways . one of the most important impacts of climate change is on crops yield so that change in temperature regime particularly maximum and minimum temperatures is noticeably change plants production . in this research , is considered to impact of climate change on water requirement ...
