National Trade can Drive Range Expansion of Bark- and Wood-Boring Beetles

摘要: Several native species of bark- and wood-boring beetles (Coleoptera) have expanded their range within biogeographic regions in the last years, but role human activity driving this phenomenon has been underinvestigated. Here we analyze 3 yr trapping records (Cerambycidae Scolytinae) collected at 12 Italian ports surrounding forests to help elucidate movement region. We trapped several that occurred either inside or outside distributional Italy. Species richness abundance those found located were most strongly associated with amount forest cover landscape, suggesting they could arrived from nearby forests. The was instead linked national imports arriving port where occurred, likely introduced other parts This study demonstrates sea transportation can favor expansion a country, confirms surround serve as source be potentially moved exports.
