the study of karst phenomena and its potentials has had always a particular importance in semi-arid zones of iran, specifically due to the lack of water sources. in this paper, we are going to discuss the landscape morphology in karstic areas, and the way we can have an ecological planning approach to it. maharlu karst basin was selected as the case study of karstic area, and kaftarak mount in ...
A substantial number of species within the tooth-carp Aphanius Nardo, 1827 (Cyprinodontidae, Teleostei) has been recorded from the endorheic drainage systems of Iran, and several isolated populations in these systems may deserve species status. Descriptions of these species and populations have been based mainly on morphological and molecular data; however, the characters related to the fish sc...
Genetic structure of an endemic tooth-carp fish, Aphanius farsicus from four different water bodies in the Maharlu Lake basin was investigated by applying five microsatellite markers. All of the five examined microsatellite loci showed polymor-phism pattern. A total of four alleles were detected at five microsatellite loci, with an average of 2.8 to 3.5 alleles per locus. Average values of obse...
In addition to biochemical, physiological and morphological analysis, molecular studies provide additional information for establishing phylogenetic relationships among different species and strains of the genus Dunaliella. In the present study, based on neighbor- joining analysis of the nuclear rDNA ITS sequence, a novel strain of the green algae Dunaliella viridis was identified from Maharlu ...
Remote sensing is increasingly used in studies of periodic changes of land use and landsurface temperature (LST) calculations. In this paper, the effect of change in the area ofMaharlu Lake on climatic elements, land surface temperature and vegetation cover in theareas surrounding the lake were studied. To this end, the ETM + & TM sensor data ofLANDSAT satellite on May 22, 1987, May 17, 2000, M...
background: groundwater nitrate pollution is an important environmental problem in water resources management. in this regard, specific measures aiming at prevention of water pollution will be helpful to managers and decision-makers. identification of aquifers’ vulnerable areas and determination of groundwater protection zones using most widely used models, such as drastic and cd, are one of th...

dunaliella salina was isolated from maharlu salt lake in shiraz, iran, and was analyzed forthe effects of salinity stress on its growth, pigment content and ascorbate peroxidase activity. growth,expressed as number of cells ml-1, which was most rapid at 2 m nacl, was reduced at salinity extremes.during the exponential phase of growth, increasing salinity from 0.5 to 4 m nacl increased chl a fro...
