The following table shows that each rattan species is associated with between 1 and 4
different ant species. A chi-square test reveals that there is little significant difference
in the number of ant species associated with a rattan than would have been expected
(P 2 = 5.71, P=0.13).

Given the above data, from the number of rattan species that each ant species visits it
appears that the majority of the species of ant are only found on one species of rattan.
There is one exception where there seems to be less of a preference and one species of
ant, Crematogaster sp. 1, visits up to eight species of rattan. The Chi-square test for
this data reveals highly significant differences between the ant species in the number
of rattans species that they use (P 2 = 25.29, P=0.00001). This is clearly due to the fact
that this species of Crematogaster is a generalist. The remaining species of ant visit
one or two species, which seems to suggest that there is a fair level of specialisation
between ants and rattan.
