A major goal of ecology is to explain differences in species richness between regions and among clades. The diversification rate of clades is a key parameter for understanding both patterns. Here, we combine phylogenetic and climatic data for 250 species of plethodontid salamanders and show for the first time that rapid species diversification is associated with accelerated climatic-niche evolu...

‎Nosemosis is one of the most prevalent bee diseases in the world causing significant ‎economic losses in the global bee-keeping industry. This cross-sectional study was conducted during April-September, 2016 to investigate the prevalence of nosemosis in different climatic regions of Iran. A total of 183 ‎apiaries were selected based on cluster sampling and the climate of apiar...

environmental management and planning and benefiting from climatic capacities of every geographical place are related to homogenous climatic regions and the most influential climatic elements in spatial separation of the climatic regions. accordingly, the aim of the present study includes determining the most influential climatic elements affecting on the climate of esfahan province, and the sp...

In Australia, peritonitis is an important cause of technique failure and infectious deaths amongst peritoneal dialysis (PD) patients. The temperature and humidity differences in individual climatic regions may influence the development of PD peritonitis by changing patient behaviour and hygiene, distribution of normal skin flora, organism virulence, and the chance of contamination. Previous stu...

Using a dataset with 16 climate variables for locations representing 813 wine regions that cover 99 % of the world’s winegrape area, we employ principal component analysis (PCA) data reduction and cluster grouping similar regions. The PCA resulted in three components explaining 89 variation data, loadings differentiate between are warm/dry from cool/wet, low high diurnal temperature ranges, nig...

Testing climatic niche divergence and modeling habitat suitability under conditions of climate change are important for developing strategies to limit the introduction and expansion of alien invasive weeds (AIWs) and providing important ecological and evolutionary insights. We assessed climatic niches in both native and invasive ranges as well as habitat suitability under climate change for eig...

the weaknesses of the traditional climatic classification methods in presenting the climatic realities of caspian region and showing the new methods' merits based on multivariate statistical methods, and geographical information system in presenting the climatic regions of caspian, are among the most important ideas of conducting this study. to do so, we used the data of synoptic stations ...

the presence of yield systematic risk in agricultural sector is one of the main reasons for facing this sector with huge damages and is one of the restricting factors in developing agricultural insurance in iran. this study explores the presence of systematic yield risk and the extent and severity of yield spatial dependence for apple production in iran. to this end, the apple production region...
