Precipitation is a key meteorological component that directly related to climate change. Quantifying the changes in precipitation bioclimate crucial planning climate-change adaptation and mitigation measures. Southeast Asia (SEA), home world’s greatest concentration of ecological variety, needs reliable monitoring such changes. This study utilized global-climate models from phase 6 coupled mode...
Biological control using natural antagonists has been a most successful management tool against alien invasive plants that threaten biodiversity. The selection of candidate agents remains a critical step in a biocontrol program before more elaborate and time-consuming experiments are conducted. Here, we propose a biogeographic approach to identify candidates and combinations of candidates to po...
The climate changes have an important role in distribution of plant species. Statistical species distribution models (SDMs) are widely used to predict the changes in species distribution under climate change scenarios. In the peresent study, the distribution of Alopecurus textilis in the current and future climate condition (2050) under the influence of climate change and two scenarios of RCP 4...
Astracantha gossypina (Fisch.) is one of the most important rangeland plants in the northeastern region of Iran and has a great role in soil conservation and the economy of ranchers. unreasonable uses and management of desire plant species usually led to species loss and the replacement of endemic and specialist species by invasive endemic or exotic species. This study was conducted to determin...
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...
