Abstract. Record highs of meltwater production at the surface Greenland ice sheet have been recorded with a high recurrence over last decades. Those melt seasons longer durations, larger intensities, or both increased length and intensity direct impact on mass balance its contribution to sea level rise. Moreover, also affects dynamics through lubrication feedback. It is still not clear how feed...

the phytoplankton structure and dynamics were analysed in relation to abiotic variables inpaso de las piedras reservoir, argentina. phytoplankton driving forces were explored using a functionalapproach. a total of 15 functional groups were identified among which d, p, h1, f, j and c were the mostimportant. a canonical variate analysis indicated that the categorization of the species in function...

The larval community of coral reef fishes in the Red Sea was studied in coastal and offshore sites to determine the effects of the exposure to waves and currents and the distance from the shore in structuring the larval fish community. Plankton sampling from inshore and offshore sites and the exposed and sheltered sides of the reefs resulted in the collection of 2048 larvae representing 49 diff...

  عدم قطعیت در بارش پیش بینی شده، یک منبع اصلی عدم قطعیت در پیش بینی بهنگام سیل می باشد. عدم قطعیت بارش از عدم قطعیت در مقدار بارش، توزیع زمانی و توزیع مکانی بارش تشکیل می شود. در این تحقیق به منظور پخش عدم قطعیت بارش در مدل پیش بینی سیل HEC-1 ، روش گسسته سازی زمانی در چهارچوب اصل بسط تئوری فازی و در ترکیب با الگوریتم ژنتیک نرمال بکار برده می شود. عدم قطعیت به علت توزیع زمانی ناشناخته بارش با ت...

The aim of the present study was to evaluate the spatial and temporal changes of NPP in different biomes of Isfahan province from 2000 to 2014 and their response to climatic factors. For this purpose, the NPP data of the MODIS satellite were collected and the map of climatic variables was produced using various interpolation methods. The investigation of the spatial and temporal variations of N...

  Background and Objectives: Environmental conditions in different geographical areas provide a basis for the spread of some diseases. Cutaneous leishmaniasis is a serious threat to public health and is one of the arthropod-borne diseases. The prevalence and distribution of this disease is affected by environmental and climatic factors. The aim of this study was to model the Spatio-temporal va...

In this study, five sequences of Landsat sensors including MSS, TM, ETM+ and OLI at unequal intervals spanning 42 years between 1973 and 2015, were analyzed to investigate the spatial and temporal variation of salt crusts in Sbzevar playa, central Iran. Landsat satellite imageries and ASTER digital elevation model were prepared, and spatial-temporal analyses were carried out in ENVI and GIS. Fu...
