saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
Climate change may pose challenges to the conservation of plant species such as the Fritillaria imperialis that have narrow geographical distribution. In this study, the modeling suitable habitats of F.imperialis in Iran was done in the current condition and under climate change (2050). For this purpose, 78 species presence data along with 12 environmental variables including bioclimatic, physi...
Lorestan newt (Neurergus kaiseri) is an endemic species which has restricted dispersal in southern Zagros Mountains in Iran, and it is listed as critically endangered in IUCN red list. Today the populations of this species are decreasing and facing serious threats. In this study, habitat suitability of Neurergus kaiseri was evaluated using a MaxEnt modelling approach according to environmental ...
Motivated by the need to solve ecological problems (climate change, habitat fragmentation and biological invasions), there has been increasing interest in species distribution models (SDMs). Predictions from these models inform conservation policy, invasive species management and disease-control measures. However, predictions are subject to uncertainty, the degree and source of which is often u...

The phenomenon of climate change is the greatest environmental challenge facing in the world today. The phenomenon is expected to affect all ecosystems in the world. Freshwater ecosystems are more vulnerable to these changes, as freshwater is exposed to various human pressures such as hydrology, morphology, connectivity and water quality. Therefore, climate change along with the mentioned issue...
