When an alien species enters a new ecosystem, it can alter the environment in a number of ways: by eating native species (in its 50 years on Guam, the Australian brown tree snake has eliminated 9 of 13 native bird species); by spreading disease among them (introduced birds in Hawaii thrive in part because they are far less susceptible to the avian malaria parasite, also an introduced species, than native birds are); or by altering the environment in such a way that favors themselves (like melaleuca, an Australian tree that is spreading through the Everglades in part by changing the frequency and intensity of fires).

The absence of a single gene tree identical to the avian species tree is consistent with studies in yeast (82), indicating that phylogenetic studies based on one or several genes, especially for rapid radiations, will probably be insufficient.
