Table 4. Evidence for clumped distribution of focal species.

Species N Area NN Ratio* z-score p-value
NKA 25 0.51 0.47 -5.0444 <0.0001
NKB 48 0.51 0.82 -2.4182 0.0156
NSA 6 0.51 0.23 -3.5940 0.0003
NSB 65 0.51 0.51 -7.4832 <0.0001

* NN Ratio = observed mean distance/expected mean distance, if NNR<1 then distribution is clumped, if NNR>1 then distribution is equally dispersed.
