At the level of European countries, a positive species-people correlation was found for ants, aphids, grasshoppers and stream macro-invertebrates (Pautasso & Fontaneto, 2008;Schlick-Steiner et al, 2008;Steck & Pautasso, 2008;Pautasso & Powell, 2009), but the data did not allow the inclusion of sampling effort in those studies. Apart from invertebrates, species-rich groups such as bacteria and fungi have been almost completely neglected from the point of view of the large-scale correlation with people (Pautasso & Zotti, 2009;Nemergut et al, 2010).…”
