Nonindigenous ants associated with geothermal and human disturbance in Hawai'i Volcanoes National Park

*[P. megacephala is the dominant ant below 1000-m elevation in Hawaii, whereas L. humile is largely absent from the Hawaiian lowlands; instead dominates areas above 1000-m elevation. At high elevations on the Big Island of Hawaii, L. humile dominates on the semiarid western slope of Mauna Kea, but does not penetrate less-disturbed parts of the more humid Kilauea Caldera region.]
