We explore in this paper how animals can be affected by variation in climate, topography, vegetation characteristics, and body size. We utilize new spatially explicit state-of-the-art models that incorporate principles from heat and mass transfer engineering, physiology, morphology, and behavior that have been modified to provide spatially explicit hypotheses using GIS. We demonstrate how tempo...

The development in recent years of new beta diversity analytical approaches highlighted valuable information on the different processes structuring ecological communities. A crucial development for the understanding of beta diversity patterns was also its differentiation in two components: species turnover and richness differences. In this study, we evaluate beta diversity patterns of ground be...

Abstract Three important aspects of ground-motion modelling for regional or portfolio risk analyses are discussed. The first issue is the treatment discretisation continuous fields generating spatially correlated discrete fields. Shortcomings present approach in which correlation models based upon point estimates ground motions used to represent correlations within and between spatial regions h...

Estimates of the earthquake ground motion intensity over a geographical area have multiple uses, that is, emergency management, civil protection and seismic fragility assessment. In particular, with reference to assessment, it is interest estimates values different ground-motion measures in order correlate them observed damage. To this purpose, present paper uses procedure recently proposed lit...

near-fault ground motions have caused very much damage in the vicinity of seismic sources during recent earthquakes. it is well known that under specific circumstances, intensive ground shakings near fault ruptures may be characterized by short-duration impulsive motions. this pulse-type motion is generally particular to the forward direction, where the fault rupture propagates towards the site...

STUDY OBJECTIVE To examine the association of spatial variation in acute myocardial infarction (AMI) incidence and its putative environmental determinants in ground water such as total water hardness, the concentration of calcium, magnesium, fluoride, iron, copper, zinc, nitrate, and aluminium. DESIGN Small area study using Bayesian modelling and the geo-referenced data aggregated into 10 km ...
