Abstract1. Despite posing a serious threat to global biodiversity, national and internationalmanagement efforts have not been able to limit the spread of most invasivespecies.

We focus on the ongoing human-mediatedinvasion of the common mynaAcridotheres tristis into the Mediterranean basin, a region rich in overall numbersof species and endemic species, where common mynas have been introducedinto a handful of countries. Some introductions were followed by subsequentrange expansions into neighbouring countries.
