Washington, March 11 (IANS) Exotic species invading new territories threaten other plants and animals there, but for all their destructive tendencies, they might also embody a surprisingly “creative” side, a new study has found. Researchers discovered that an invasive population of the freshwater snail (M tuberculata) on Martinique island harbours tremendous genetic variation for key traits like fecundity, juvenile size and age at first reproduction - implying a potential for evolutionary change.
“It is widely believed that despite their tremendous ecological success, invasive populations, being founded by few individuals, lack genetic variability for important traits,” said French scientist Beno
