Over time, non-native plant species increasingly integrate into native food webs. Their region of origin or relatedness to native plants plays only a minor role. Far more decisive is how widely they have spread and how long they have been growing in Europe. The longer they have been established and the wider their distribution range, the more they are used by microherbivores such as leaf miners, gall midges and aphids – leading to similarly diverse interactions as with native plants. These are the findings of researchers from Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv), led by Dr Ingmar Staude. They have just published their study in the journal Ecology Letters.
