Interesting search tool - Chris's research prompted me to do a little digging of
my own. I was struck by the fact that there are surprisingly few fishes listed
as S5 in Mississippi, so I did a database query on gambusia affinis. Well, that
one actually DID rank S5 for Mississippi, but in Arkansas, our next-door
neighbor, it is listed as S4, as it is in some other states. There is an
interesting map which shows conservation status by color for each state. I
wonder if Arkansas ranks ANY fish S5, if our good friend Damnbusia can't make
the grade?

always votes for the candidates promising the most money from
the public treasury with the result that a democracy always collapses over loose
fiscal policy followed by a dictatorship."
