Ragni e biondicazione: esperienze a confronto in Piemonte

Spiders and bioindication: field researches in Piemonte - Spiders encompass a set of remarkable features that validate their use as good environmental indicators and, in agronomy, as potential pest controllers. A three years research project of the Department of Animal and Man Biology of the University of Turin confronted data from several field researches at different levels of biological organisation. The study took place in Piedmont from 2002 to 2005. The synthetic work here presented gives an account of the most remarkable results and provides the list of the publications of the authors related to this research. An amount of 9784 spiders have been collected, belonging to 328 species, 212 genera and 36 families. The analysis of the spatial and temporal successions of the spider assemblages offers a remarkable approach to biodiagnostic purposes and particularly to the analysis of the evolution and the stability of different biotopes when the structure of vegetation is influenced by human activity.
