Transferred to new environments by human activity, they become competitors or predators of local species, which are often unable to withstand the incursion. An international research team, involving two French laboratories, have evidenced an aspect of these invasions: species charisma. The popularity of a species and its perception by society and the media, they concur, determines how it is introduced and what impact it has on its new surroundings. In Italy, for example, the arrival of the popular North American grey squirrel threatens the existence of the native red squirrel. "Charisma is used in the literature to refer to the “attractive...
