The Iranian cave barb (Iranocypris typhlops Bruun & Kaiser, 1944) is a rare and endemic species of the family Cyprinidae known from a single locality in the Zagros Mountains, western Iran. This species is "Vulnerable" according to the IUCN Red List and is one of the top four threatened freshwater fish species in Iran. Yet, the taxonomic position of I. typhlops is uncertain. We examined phylogen...
مطالعه سازوکار رشد چین های مرتبط با گسل در میادین نفتی در ارائه راهکار های مناسب برای اکتشاف و بهره برداری مواد نفتی نقش شایانی دارد. در این پژوهش با استفاده از شاخص های ریخت زمین ساختی، الگوی چین خوردگی وابسته به گسل در دو میدان نفتی پارسی و پازنان واقع در فروافتادگی دزفول مورد مطالعه قرار گرفته است. شاخص های ریخت زمین ساختی از قبیل الگوی فرسایش بستر آبراهه ها، نسبت دایره ای بودن و انتگرال فرا...
1. introduction mountains are the main sources of turbulence and change in the shape of atmospheric flows, and they can cause airflow upward as well as clouds formation and rain through productive mechanisms such as upslope condensation and convection. they also have an important effect on regional and world precipitation turbulence (banta, 1990; barros & lettenmaier, 1994), and can cause sever...
One of the more intractable problems that archaeobiologists struggle with is how to characterise ancient subsistence systems when the plant and animal remains that we study are incommensurate in so many ways. Three examples from the upper Euphrates and Iran illustrate how changes in plant remains are associated with changes in animal exploitation. Two of them consider the agropastoral continuum...
INTRODUCTION Studying human errors as a risk factor in the occurrence of accidents is necessary. Thus, the aim of this study was to identify, predict and control human errors in industrial control units. METHOD This is a case study carried out using SHERPA in the first unit of Zagros Methanol of Asalooyeh, Iran, and its subunits. To collect the required data, various methods were used: observ...
Genetic differentiation in natural populations is driven by geographic distance and by ecological or physical features within and between natural habitats that reduce migration. The primary population structure in wild barley differentiates populations east and west of the Zagros Mountains. Genetic differentiation between eastern and western populations is uneven across the genome and is greate...
Conservation of biological diversity is one the most important issues in conservation biology, so a wide range quantitative spatial methods have been used to determine biodiversity hotspots and priority areas. The main aims present study are determining areas endemism as well centers genus Onosma based on GIE, IPAs, species richness, AZE-like criteria approaches, assess status priorities mentio...
