Non-Native Ant Invader Displaces Native Ants But Facilitates Non-Predatory Invertebrates, Robert Warren, Madeson C. Goodman

Biology Faculty Datasets

Many invasive ants, such as the European fire ant (Myrmica rubra), are particularly successful invaders due to their ability to form multi-nest, multi-queen 'supercolonies' that appear to displace native invertebrates in invaded regions. Myrmica rubra has invaded many areas in the Northeastern United States, including Western New York. Myrmica rubra invasion corresponds with decreases in native invertebrates, particularly ants, an effect which may be attributable to direct displacement, or because M. rubra prefers habitat unsuitable for native ants. We surveyed Western New York parklands to investigate native ant and non-ant invertebrate abundance in M. rubra-invaded and …
