(a) 1st to 6th nearest neighbor indices for the three populations (means ± 95% confidence limit intervals). Confidence limit intervals below and above 1 suggest clumped or regular patterns, respectively. 1st to 4th NNIs point to a more clumped spatial pattern while the 5th to 6th NNIs suggest a more regular one. (b) The negative correlation of host colony densities in each plot in the NY population with the spatial pattern (NNI), for the 1st to 6th nearest neighbor indices. Nearest neighbor distances decrease as density increases, but the NNI is already corrected for host density.
