THE ENVIROMENTAL PROBLEMS OF THE PIANA DEL SIGNORE (GELA, SICILY) FOR A CORRECT AGRONOMIC, CULTURAL AND LANDSCAPE UPGRADING AND ENHANCEMENT OF THE AR…
2017
In Sicily it is witnessing an environmental degradation that can be conducted to the human activity and the already known process of desertification. The present study had as object the c/da Piana del Signore in plain of Gela being an area characterized by an extreme aridity and salinity. Through consultation and study of the various researches realized on the area, the various environmental and territorial characteristics outlined, highlighting the issues and possible improvements. The objective was to outline the damages caused by man proposing possible routes for a correct requalification of the area in order to enhance a landscape of great agronomic and naturalistic interest. In fact to…
Spatial microbial community structure and biodiversity analysis in "extreme" hypersaline soils of a semiarid Mediterranean area
2015
In recent years specific attention has been paid on the biotechnological potential of microorganisms in extreme soils, in particular in saline soils. Salinity is one of the most widespread soil degradation processes on the Earth, and saline soils can be defined as extreme soils or border line habitats in which several factors, as high salt content, may limit the growth of organisms. In this study, the physical, chemical and microbiological soil properties were investigated in the shallower horizon of natural saltaffected soils in Sicily (Italy). The main aim of the research was to evaluate the structure and diversity of bacterial and archaeal communities by terminal-restriction fragment len…
