Remarks on required reading:
The bar chart shown in Habits' Ch 3, [33], Fig 9 appears to illustrate the frequency of occurrence of species set counts within the set of sites in NYC. It varies significantly from Cartesian coordinate system in a way that
on the horizontal axis the numbers are represented by line segments, not points on the line. Can we say that it represents data bins with a width of 1 ? I think it would be little bit more helpful if all segments were labeled, which for the sake of readability could be achieved by placing the labels in 2 raws in an alternating "checkerboard" fashion. This could make reading which bar represents which count integer easier.

I think the more accurate description of the data table Figure 8 would be: "Number of specimens per specie per site". Its actually a 3-dimensional data matrix (?)
