In Mediterranean climates, the most important ecological factor for natural vegetation as well as for crops is low summer rainfall coinciding with a period of maximum temperatures creating a more or less prolonged period of intense drought. During the summer, water stress enhances the differences between adjacent landscape elements in terms of plant biomass distribution giving way to increased vegetation cover heterogeneity. The aim of this article is to use variogram analysis to quantitatively estimate water stress-induced oscillations in remotely sensed biomass spatial distribution of Sardinia (Italy).

Abstract
In Mediterranean climates, the most important ecological factor for natural vegetation as well as for crops is low summer rainfall coinciding with a period of maximum temperatures creating a more or less prolonged period of intense drought. During the summer, water stress enhances the differences between adjacent landscape elements in terms of plant biomass distribution giving way to increased vegetation cover heterogeneity. The aim of this article is to use variogram analysis to quantitatively estimate water stress-induced oscillations in remotely sensed biomass spatial distribution of Sardinia (Italy).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
