City and human are two different human-made and natural systems which has an effect on each other. The formation of a residence depends on the climatic conditions. Construction of a residence shows that people have adapted themselves and their activities to it; while the climatic conditions play an important role in comfort in human environments. Thus, the buildings and environmental spaces sho...

PREMISE OF THE STUDY For many plant species, historical climatic conditions may have left lasting imprints that are detectable in contemporary populations. Additionally, if these historical conditions also prevented gene flow among populations, these populations may be differentiated with respect to one another and their contemporary environmental conditions. For the fern, Vittaria appalachiana...

Climatic conditions shift gradually over millennia, altering the rates at which carbon (C) is fixed from the atmosphere and stored in the soil. However, legacy impacts of past climates on current soil C stocks are poorly understood. We used data from more than 5000 terrestrial sites from three global and regional data sets to identify the relative importance of current and past (Last Glacial Ma...

Inferences of past climatic conditions from a sedimentary record from Big Lake, British Columbia, Canada, over the past 5,500 years show strong millennial-scale patterns, which oscillate between periods of wet and drier climatic conditions. Higher frequency decadal- to centennial-scale fluctuations also occur within the dominant millennial-scale patterns. These changes in climatic conditions ar...

The evolution of climatic niche specialization has important implications for many topics in ecology, evolution and conservation. The climatic niche reflects the set of temperature and precipitation conditions where a species can occur. Thus, specialization to a limited set of climatic conditions can be important for understanding patterns of biogeography, species richness, community structure,...

Background: Changing the climatic pattern can lead to major changes in the geographical distribution of infectious diseases. The aim of this study was to investigate the effect of climate change on the favorable bio-climatological zone for leishmaniasis sand-fly living which is a vector of Leishmania in Iran. Materials and Methods: Data of the climatic factors affecting the biology of sandflies...

Calculations of energy efficiency of several AACbased building envelopes under different climatic conditions are presented. As thermal insulating materials, expanded polystyrene and hydrophobic and hydrophilic mineral wools are assumed. The computations are accomplished using computer code HEMOT developed at Department of Materials Engineering, Faculty of Civil Engineering at the Czech Technica...
