the coastal areas of the caspian sea are geographically unique and provide habitats for different flora and fauna. one of the remarkable inhabitants of this area is the european pond turtle, emys orbicularis (linnaeus, 1758), about which very little is known. in our study thirty seven (37) adult males of e. orbicularis have been identified in the golestan, mazandaran, ardebil, and east azerbaij...

The number of studies on extremophilic organisms has grown exponentially in the last few years. These exotic organisms (extremoplilees) are adapted to living at 100 c. In volcanic springs, at low temperatures in the cold polar seas, at high pressure in the deep sea, at very low and high ph values (ph 0-1 or ph 10-11) or at hight salt concentration (35%). Recent developments clearly show that ce...

Many real-world spatially related problems, including river-basin planning and management, give rise to geographical information system based decision making, since the performance of spatial policy alternatives were traditionally and are still often represented by thematic maps. Advanced technologies and approaches, such as geographical information systems (GIS), offer a unique opportunity to ...

in certain environments such as iran highlands, major innovations in lifestyle, as the emergence of agriculture and domestication of animals, are thought to have led to population expansions. historical studies showed that at some point in history (from the third to the first millennium bc) dramatic changes have been taken place on the iranian plateau. to trace the genetic affinity between the ...

human activities such as oil and gas production can enhance the natural level of naturally occurring radioactive materials (norm) in by-product and waste streams. iran has been among the top five oil producing countries since 2005. this high production rate emphasizes the importance of norm management to ensure the safety of humans and wildlife. petroleum storage and transport facilities are lo...
