The objective of this study was to estimate the potential distribution of Rhyssomatus nigerrimus in Mexico. Point presence data and bioclimatic data were used to construct the model. Kernel density distributions were estimated for the bioclimatic layers to represent the response function and to combine them. The vulnerability of municipalities planted with soybean was computed as a function of ...

Concern over implications of climate change for biodiversity has led to the use of bioclimatic models to forecast the range shifts of species under future climate-change scenarios. Recent studies have demonstrated that projections by alternative models can be so variable as to compromise their usefulness for guiding policy decisions. Here, we advocate the use of multiple models within an ensemb...

this paper examines the utility of the air pollution model (tapm) in simulating meteorology and dispersion of pm10 and wind data in order to assess the impacts of wind variability function on urban heat island for the day of 25, november, 2012 in karaj city that experienced severe degradation in air quality. drawing, skew-t diagrams, maps of surface pressure (500hp), omega (850hp) and atmospher...

It has been argued that widespread extinctions of top predators have changed terrestrial ecosystem structures through mesopredator release, where increased abundances of medium-sized predators have detrimental effects on prey communities. This top-down concept has received much attention within conservation biology, but few studies have demonstrated the phenomenon. The concept has been criticiz...

Vernacular architecture based on bioclimatism concepts was developed and used through the centuries by many civilizations across the world. Different civilizations have produced their own architectural styles based on the local conditions. This study is carried out on the vernacular buildings of north-east India across all the bioclimatic zones. A survey of 42 houses, more than 70 years old was...
