Extinction vs accuracy

Chris, Ron and others,
The reason I believe there is a scientific consensus that the term extinction
should apply to local populations also is that the scientific literature is
full of that usage. This is especially true of the island biogeography and
metapopulation literature, but also the population genetics literature.
To cite examples, look at these recent books:
John Avise 2000. Phylogeography: the history and formation of species. Harvard
University Press.
Peter Grant (ed.) 1998. Evolution on Islands. Oxford University Press.
James Brown 1995. Macroecology. University of Chicago Press.
Ilkka Hanski 1999. Metapopulation Ecology. Oxford University Press.
As an expert on stochastic extinction processes I am familiar with this
literature. I am just attempting to assess the literature when I state that
there seems to be a scientific consensus accepting the term 'extinction' for
both local and global extinction. If the examples above don't convince you,
perhaps it would be good to read some of this literature.

ps The US president select is one of the most embarrassing figures in all of
our nation's presidential history. He prides himself on his ignorance and
incuriosity. (As reported today in the Drudge report, W doesn't even know the
name of the man who selected him president Antonin, not Anthony, not Antonio
Scalia). Most pertinently, his choice for interior secretary, while smarter and
more knowledgeable than W, is a member of the wise use movement, is a green
scammer, and is not likely to be a good steward of the common land I share
with other American citizens. For this and other political reasons, I expect
the
next four years to be a painful moment in our environmental history. It will
probably radicalize another generation of conservationists. It certainly means
that conservationists will become more outspoken. Live with it or hire someone
with brains. For absolute clarity: 1) I am not against butterfly collecting,
2) I am not denying anyone their freedom of religion, 3) I am oppressed by
ignorance, stupidity, avarice and waste.
