Predicting species' responses to the combined effects of habitat and climate changes has become a major challenge in ecology and conservation biology. However, the effects of climatic and habitat gradients on species distributions have generally been considered separately. Here, we explore the relationships between the habitat and thermal dimensions of the ecological niche in European common bi...

One of the major concerns with a potential change in climate is that an increase in extreme events will occur. Results of observational studies suggest that in many areas that have been analyzed, changes in total precipitation are amplified at the tails, and changes in some temperature extremes have been observed. Model output has been analyzed that shows changes in extreme events for future cl...

Monitoring of permafrost along the Qinghai-Tibet (Xizang) Highway shows that there is a large difference in the response of permafrost to climate change and to engineering construction. The change in cold (,21.5uC) permafrost is greater than that in warm ($21.5uC) permafrost under the effect of climate change, while the cold permafrost is less sensitive to the disturbances from engineering acti...

The objective of the study was to describe seasonality of hospitalizations for heart failure in tropical climate as it has been described in cold climates. Seasonal Auto-regressive Integrated Moving-Average model was applied to time-series data of heart failure hospitalizations between 1996 and 2004 in Niteroi (Southeastern Brazil), collected from the Brazilian National Health Service Database....

The evolution of viviparity is a key life-history transition in vertebrates, but the selective forces favoring its evolution are not fully understood. With >100 origins of viviparity, squamate reptiles (lizards and snakes) are ideal for addressing this issue. Some evidence from field and laboratory studies supports the "cold-climate" hypothesis, wherein viviparity provides an advantage in cold ...

This study was carried out to investigate the egg production performance and egg quality characteristics of the indigenous ‎chickens reared in rural areas of two different climates of Isfahan province. Totally, 2160 indigenous chickens were studied in ‎this research. Two dominant climatic regions (cold and ‎hot) were determined for Isfahan province. In each climate, two towns and three villages...

introduction climate has always been one the main factors of designing urban spaces in iran since past centuries. by analyzing urban spaces it can be concluded that different cities have different urban spaces due to climate differences. one of the main reasons of the differences in the type and orientation of urban spaces is the climate as one of the key factors in designing these areas. regar...

the process of constructing buildings is a complex activity, which has a variety of impacts on our environment, society and economy. buildings provide shelter, encourage productivity, embody our culture and can create a great legacy for the future while at the same time establishing links with the past. but they also consume a huge share of our land, energy, water and material resources. regard...
