The dotted line shows what the relationship would look like if predator and prey
The size differential between predator and prey
was often less than 20 mm.
The effects of predation on both predator and prey
populations change as prey densities vary.
Average speeds of predator and prey
populations before and after a one-round simulation.
It is hoped that the experiments will eventually show the predator and prey
robots mimicking behaviour seen in the natural world such as prey herding for protection and the predators using pack strategies.
If stochasticity in primary productivity is superimposed on a long-term cycle, which might be caused by cyclical variation in climate, for example, the cycle may be seen in the predator and prey
populations (Figure 3c).
In their words: ``In the wild, the relationship between predator and prey
defines the daily routine of virtually every animal alive.
Disturbing this balance can have disastrous consequences for both predator and prey
, he says.
