Las interacciones ecológicas y sociales afectan las respuestas conductuales de los organismos. Las sociedades de hormigas en mutualismos obligados con plantas son una pareja fascinante para estudiar la co-evolución. La planta y las necesidades que esta crea en la sociedad de las hormigas moldean el comportamiento y la morfología de los miembros de la sociedad.
