Re: cf. vs. aff.

[Piabinha@aol.com]

ok, mike, it sounds to me that the major diff. (albeit a slight one) is that 
cf. means "different from, but probably same species as, please compare" 
whereas aff. means "similar to, but probably different species."

<< A subspecies is presently  considered as nothing but a population within a 
valid
 species. >>

we had a discussion about the concept of species in the livebearer list 
(which gave me a major headache...).  so, in your mind, the several 
"subspecies" of tigers, for example (siberian, west asian, sumatran, javan, 
bengal etc.) are populations?  or separate species?  i always assumed they 
were universally considered to be subspecies (at least in the old view) but 
apparently some newer thinking would even put them in separate species.
