1. Sneаky Snаkes During the 1940s, militаry ships frоm the Sоuth Pacific accidentally intrоduced brown tree snakes from Australia to the island of Guam. These snakes eat birds, lizards, and small mammals in their native range of Australia. Since no species on Guam eats the snakes, their population has grown rapidly. Researchers estimate that two million tree snakes now inhabit the island. So far, 10 species of birds and 5 species of lizards have disappeared from Guam; small mammals have also decreased in abundance. Since the brown tree snake is a keystone species in Guam, it must also be a keystone species in Australia. True or False?
