Abiotic influences on the behaviour of rodents, ants, and plants affect an ant-seed mutualism

Deserts are open environments characterized by striking shifts in temperature and light regimes. We hypothesized that the abiotic environment mediates the interaction between an ant-dispersed plant, Datura wrightii (Solanaceae), ant mutualists, and rodent seed predators in the Sonoran Desert. Field...
