What happens when two species are grown together? One of the first careful experiments of this kind was performed by Gause (1935). He grew two different species of Paramecium both separately and together under laboratory conditions. The results he obtained are graphed in Figure 7.1. As you might guess, the number of each species was lower when the two species were grown together than when each was grown individually. Similar experiments have been performed many times since.
