I sent this message to the list a few days ago, and now must apologize
to the list and to the authors of the article I cited above.

First, it was simply inappropriate to send this message to the list
with the citation included, as I had not first checked with the authors
of this article to verify that this was an instance of use without
citation.  As it turns out, the authors of the article did not use 
the r.le programs.

I came to the mistaken conclusion that the r.le programs were used
without citation because I first missed the citation to SPAN that is
included in the caption to Table 2.  I also assumed that certain other
calculations the authors made using GRASS (calculating a map of distances
from each cell to a particular category, making a moving window map,
and calculating a dominance index) could not have been made without
using the r.le programs.  As it turns out, one of the authors, Dr.
William Hargrove, simply created his own scripts to do part or all of
these calculations in tandem with existing GRASS programs.

I apologize to the authors of this article for falsely attributing a
breach of scientific etiquette, when in fact I was the one in error,
and this false accusation was itself a breach of acceptable conduct.
