英文摘要: Climate warming and the poleward widening of the tropical belt have induced range shifts in a variety of marine and terrestrial organisms. Among the key taxa that are rapidly expanding their latitudinal range are symbiont-bearing foraminifera of the genus Amphistegina. Analysesof foraminiferal faunas from new sites in the western Ionian Sea (Ithaka and Lefkada Islands) show that amphisteginid foraminifera continue to expand their biogeographic range, rapidly outcompete all native species and represent the most abundant taxon at almost every site colonized. The introductionand range expansion of Amphistegina puts significant pressure on local species, affects foraminiferal diversity and decreases species richness of associated biotas. Native species richness is reduced at all sites invaded...
