Figure 4. Number of upland species (¤), lowland species (x) and their sum (all species z) that we observed on our Cyclops summit transect, as a function of elevation. As expected, lowland species decrease in number with elevation and disappear several hundred metres below the summit. Also as expected, upland species initially increase in number with elevation, but they then decline above 1,200 m to only eight species at the summit.
