mounds; tussocks growing variously moss, grass,
shrubs, etc.; and ground nests on bare ground or
ground covered by grass, herbs, moss or lichen.
Data analyses
We ran Non-metric Multidimensional Scaling
(NMS; e.g., Borg & Groenen 1997) for the ant
data to examine the distinctiveness of the ant
faunas of different habitat types, and to explore
the potential for different environmental variables
(see above; for a formal test on their significance,
see below) in explaining these observations
