Pest Risk Assessments (PRAs) routinely employ climatic niche models to identify endangered areas. Typically, these models consider only climatic factors, ignoring the 'Swiss Cheese' nature of species ranges due to the interplay of climatic and habitat factors. As part of a PRA conducted for the European and Mediterranean Plant Protection Organization, we developed a climatic niche model for Par...
Rangelands are one of the most vulnerable parts concerning the climatechanges‟ impacts. These impacts are even stronger in the arid and semi-arid areas whererangeland ecosystems are in critical conditions. Therefore, it is crucial to figure out theactual dynamics of climate variations on the rangelands. The aim of this research was todetermine climate changes in Khabr rangeland, Kerman, Iran. S...
Introduction: Refineries are considered as the base of many accidents and incidences due to their close proximity with dangerous substances, products, and production processes. This study analyzed the consequences of H2S leakage scenario from clot stuck unit of South Pars Gas Refinery and determined the dangerous boundaries and the risk limits of this scenario. Methods: This was a descriptiv...
The main synoptic meteorological features influencing Chile are: (a) Pacific anticyclone (PA), (b) coastal low (CL), (c) what has been called enhancement of coastal low (ECL) a nucleation of the CL frequently observed during summer in Central Chile, and (d) subtropical lows (STL) and subpolar lows (SPL). The SPL will not be considered in the present paper. All four features can be identified wi...
During every climatic era Life on Earth is constrained by a limited range of climatic conditions, outside which thriving and then surviving becomes difficult. This applies at both planetary and organism (species) levels. Further, many causal influences of climate change on human health entail changes-often disruptive, sometimes irreversible-in complex system functioning. Understanding the diver...
Warmer and drier climatic conditions are projected for the 21st century; however, the role played by extreme climatic events on forest vulnerability is still little understood. For example, more severe droughts and heat waves could threaten quaternary relict tree refugia such as Circum-Mediterranean fir forests (CMFF). Using tree-ring data and a process-based model, we characterized the major c...
Understanding how climate change can affect crop-pollinator systems helps predict potential geographical mismatches between a crop and its pollinators, and therefore identify areas vulnerable to loss of pollination services. We examined the distribution of orchard species (apples, pears, plums and other top fruits) and their pollinators in Great Britain, for present and future climatic conditio...
summery output of global climatic scenarios resulted from large-scale predictions (usually 125 to 500 km network) of gsm models are not appropriate for important applications. because small-scale spatial variability due to factors such as land cover, topography, etc., has a significant impact on climatic variables of desired area and some processes such as runoff are sensitive to this variabili...
The study of life history variation is central to the evolutionary theory. In many ectothermic lineages, including lizards, life history traits are plastic and relate to several sources of variation including body size, which is both a factor and a life history trait likely to modulate reproductive parameters. Larger species within a lineage, for example tend to be more fecund and have larger c...
