Life expectancy and foraging risk

We are familiar with the idea that with increasing experience individual ants will develop longer foraging routes. This, of course, makes perfect sense in regard of the gradual learning of new route information. This lovely paper form Moron et al, show how this also makes perfect sense in regard to risk. By manipulating the life expectancy of foragers they show how a low life expectancy leads to higher risk taking as evidenced by foraging for longer at high temperatures, travelling further and visiting areas with a high density of predators.
