Forecasting the consequences of climate change is contingent upon our understanding of the relationship between biodiversity patterns and climatic variability. While the impacts of climate change on individual species have been well-documented, there is a paucity of studies on climate-mediated changes in community dynamics. Our objectives were to investigate the relationship between temporal tu...

Climatic characteristics adapted to human comfort are the functions needed for tourists to choose a tourism destination. This parameter has a major role in preparation of tourism calendar. Desert tourism is one of the important destination so Eco-tourist. Iran has unique capabilities in this field because of its geographical- climatic condition. In this article we have tried to provide a touris...

The national resurgence of human West Nile virus (WNV) disease in 2012 raised questions about the factors responsible for WNV outbreaks. Interannual climatic variations may influence WNV amplification and transmission to humans through multiple pathways, including mosquito breeding habitats, gonotrophic cycles, extrinsic incubation, avian communities, and human behavior. We examined the influen...

This paper focuses on the performance of Iwan as one of the significant spaces in the traditional architecture of Iran. The aim of this study is to investigate on the role of Iwan in sustainability enhancement of traditional houses of different climatic regions of Iran. Iwan is considered as a semi-open space, which its form and location in the building highly depends to the climatic situation ...

Speciation often has a strong geographical and environmental component, but the ecological factors that potentially underlie allopatric and parapatric speciation remain understudied. Two ecological mechanisms by which speciation may occur on geographic scales are allopatric speciation through niche conservatism and parapatric or allopatric speciation through niche divergence. A previous study o...

The livestock production system is considered equally sensitive to climate change as that of core agriculture system and at the same time livestock itself is also contributing to the phenomenon. The present paper attempts to analyze the sensitivity of livestock productivity in rainfed regions to climatic variability, significance of climate change with respect to Indian livestock and mitigation...

Citrus is produced commercially in over 30 countries worldwide. The major growing regions are located primarily between 40° north-south latitude where minimum temperature is generally greater than 20°F. Within these latitudes there are several important climatic areas that affect the growth and development, yields, and fruit quality of citrus. These include the low, middle, and high tropical re...

Understanding the climatic characteristics of a region plays a key role in sustainable development. The Esfahan province is extensive this factor has caused it variety climates. The regionalization climate of Esfahan has conducts with new methods of regionalization such as factor analysis and cluster analysis. The 25 variables have been selected from 12 stations for this purpose. The investigat...

Vegetation dynamics are sensitive to climatic warming and affected by individual or combined factors at different temporal scales with intensities. Previous studies have unraveled the relationships between vegetation factors; however, it is unclear whether effects of single on dominant for scales, types, regions. The objective this study was explore scale-specific univariate multivariate contro...

Metrics that synthesize the complex effects of climate change are essential tools for mapping future threats to biodiversity and predicting which species are likely to adapt in place to new climatic conditions, disperse and establish in areas with newly suitable climate, or face the prospect of extirpation. The most commonly used of such metrics is the velocity of climate change, which estimate...
