Doug, I don't understand the parenthetical "(morpho)" in your comment
above. In particular, why should (bio)diversity studies be limited to
_morpho_ species? (I am not asking about your concern with diversity
studies that use "higher" level categories as the basis for comparisons
--I think I understand your point of view on that issue. I'm asking
whether you believe that there are no other _functional_ (or
biological/evolutionary) "low-level" categories than _morpho_ species
which can form the basis of useful biodiversity studies?
If not, I guess it would help, me at least, to know what your
morpho-species encompasses (in the overall scheme of functional
biological/evolutionary units (plants, animals, etc.) which make up a
"community" [I use the term loosely/broadly here] of more or less
interacting organisms, so I can better appreciate the morpho-species
(exclusive?) relationship to the notion of biodiversity.
