A comparative study between Solenopsis invicta and Solenopsis richteri on tolerance to heat and desiccation stresses.

Solenopsis invicta and Solenopsis richteri are two very closely related invasive ant species; however, S. invicta is a much more successful invader. Physiological tolerance to abiotic stress has been hypothesized to be important to the success of an invasive species. In this study, we tested the hyp...
