Mediumand long-term runoff forecasting is essential for hydropower generation and water resources coordinated regulation in the Yellow River headwaters region. Climate change has a great impact on runoff within basins, and incorporating different climate information into runoff forecasting can assist in creating longer lead-times in planning periods. In this paper, a multimodel approach was dev...
Despite the recent droughts in Isfahan province, climatic changes and the rising trend of population growth, as well as development of industrial and agricultural activities, are exposed to the water crisis. Thus, in order to tackle this problem, the essential strategies should including exploring virtual water and water foot print for strategic crops in agricultural sector should be taken into...
“T are neither carnivores nor reptiles in Tahiti,” wrote Paul Gauguin in his journal Noa Noa. “The only ‘wild game’ on the island are the pigs which have escaped into the forest, where they have multiplied and become entirely wild.” The artist’s first impression after the long voyage, “sixty-three days of feverish expectancy,” was “nothing very extraordinary; nothing, for instance, that could b...
In Charles Dickens' A Christmas Carol, Jacob Marley, Scrooge's former partner appeared to Scrooge in a ghostly apparition. "You don't believe in me," observed the ghost. "I don't," said Scrooge. "What evidence would you have of my reality beyond that of your senses?" "I don't know," said Scrooge. "Why do you doubt your senses?" "Because," said Scrooge, "a little thing affects them. A slight dis...
abiotic factors, as topographic and physicochemical properties of soil, are the most important effective factor on vegetation in rangeland ecosystems which have the most important performances to forming and succession of plant vegetation. ecologic management of rangelands can be desired by better understanding of these effective factors. then, rangeland of javaherdeh (ramsar) in the northern a...
sustainability creates solutions that solve the economic, social and environmental challenges. it has been studied and managed over many scales of time and space and in many contexts. the paper reviews the definitions of sustainability respecting the ecologic concept as well the need for balanced sustainability within its three pillars on equal way, then it goes throw ecologic architecture with...
Analyses of leaf megafossil and dispersed leaf cuticle assemblages indicate that major ecologic disruption and high rates of extinction occurred in plant communities at the Cretaceous-Tertiary boundary in the Raton Basin. In diversity increase, the early Paleocene vegetational sequence mimics normal short-term ecologic succession, but on a far longer time scale. No difference can be detected be...
mosque architecture is considered as a potent visual symbol of the islamic architects’ design ability. prayer-hall as the manifestation of equality between the believers and the unity of architectural space has challenged such an ability throughout the history. this study, considering the characteristics of light-openings in the domes of iranian mosques’ prayer-hall, aims to investigate these d...
Biodiversity can buffer ecosystem functioning against extreme climatic events, but few experiments have explicitly tested this. Here, we present the first multisite biodiversity × drought manipulation experiment to examine drought resistance and recovery at five temperate and Mediterranean grassland sites. Aboveground biomass production declined by 30% due to experimental drought (standardised ...
