Projections of climate change impact are associated with a cascade of uncertainties including in CO2 emission scenarios, climate models, downscaling and impact models. The relative importance of the individual uncertainty sources is expected to depend on several factors including the quantity that is projected. In the present study the impacts of climate model uncertainty and geological model u...

The aim of this paper is to increase understanding of the relative importance of the input of geographic and local environmental factors on richness and composition of epigaeic steppe beetles (Coleoptera: Carabidae and Tenebrionidae) along a geographic (longitudinal/precipitation) gradient in the Inner Mongolia grassland. Specifically, we evaluate the associations of environmental variables rep...

Many studies show that species richness is correlated with climate, especially among local sites within a region. However, few studies have addressed how these climate– diversity relationships actually arise. Only a few processes can directly change species richness (i.e., speciation, extinction, dispersal), and these processes may be best studied by incorporating a phylogenetic perspective. He...

Paper undertakes software based numerical simulations in two different traditional houses in cold-dry climate of Tabriz and hot-arid climate of Yazd, The Eco Test software chosen for BIM simulations. Case study on real houses instead of hypothetical models can give more tangible results and choosing traditional houses can provide a good opportunity to compare both physical and thermal condition...

Few studies have examined the impact of safety climate upon occupational safety behavior or intentions, focusing instead on the event of incidents and injuries. Similarly, while safety climate has been studied in numerous industrial settings, limited attention has been given to the motor vehicle fleet context. This study conceptualized safety climate and work-related driver safety within a mode...
