Underground Army Ants Can't Take the Heat (IMAGE) Drexel University Caption Army ants, the nomadic swarming predators underfoot in the jungle, have a range of different lifestyles. Some species are active aboveground, some below, and some use both environments. According to a new study from Drexel University, underground species of army ants are much less tolerant of high temperatures -- and that difference in thermal tolerance could mean that many climate change models lack a key element of how animal physiology could affect responses to changing environments.
