vegan metaMDS question

The design decision in metaMDS says that it uses:

Minchin, P.R. (1987) An evaluation of relative robustness of
techniques for ecological ordinations. Vegetatio 71, 145-156.

This is the paper that I found by the same name.  Is this the correct reference?

Minchin, Peter R.1987. An Evaluation of the Relative Robustness  of
Techniques for Ecological Ordination. Vegetatio. Vol. 69, No. 1/3:
89-107.

In this paper the double standardization (wisconsin()) is used then a
centering by species is preformed.  The centering by species isn't
incorporated in the metaMDS methodology, is it?  Is there a reason for
this, or am I missing something?
best regards,

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
