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 (?)
