Abstract

Modifications to climate, occurring frequently and over increasingly short periods, lead to changes in the flora of specific territories. The changes in the composition of several florae originally surveyed in different periods highlight the fact that reduction in the availability of water leads to an increase in therophytes and to a drastic reduction of hemicryptophytes. This phenomenon has been observed on some of the small Sardinian islands which, when compared with studies carried out there in previous years, now show evidence of significant alteration in their floristic composition.
