Invasive plant outcompeted by its native ancestors
Invasive plants are believed to double-profit from loss of natural enemies and subsequent evolution of less chemically defended but more competitive genotypes, which take over their new habitats. In Ecology Letters, April, offspring from invasive North American populations of garlic mustard were out-competed by those from native European populations, having evolved to be less competitive, due to a lack of competitors in invaded habitats.

European fire ant impacts forest ecosystems by helping alien plants spread
An invasive ant species that has become increasingly abundant in eastern North America not only takes over yards and delivers a nasty sting, it's helping the spread of an invasive plant species. The ants are very effective dispersers of invasive plant seeds and new research suggests that together they could wreak havoc on native ecosystems. (2014-12-23)

Risk of extinction cascades from freshwater mussels to a bitterling fish
Reproduction of native and invasive bitterling fishes and their hybridisation was studied in Japan. We collected mussels in which these bitterlings lay their eggs, kept them in aquaria, collected eggs/larvae ejected from mussels, and genotyped them. We found that hybrids occurred when local mussel density was low. The rapid decline of the host mussels and artificial introduction of an invasive congener interacted to cause the rapid decline of a native fish. (2021-01-04)

Study shows native plants regenerate on their own after invasive shrubs are removed
Invasive shrubs have become increasingly prevalent in the deciduous forests of eastern North America -- often creating a dense understory that outcompetes native plants.
