Russell -
I agree that it is a surprisingly large number. I've been looking for
a way to validate or repudiate it myself.
I suspect the numbers are significantly inverted in relatively wild
places like the American West, Canada, Australia and the Russian Steppes.

Sorry - I missed that he was only talking about one phylum. The way it
was phrased mislead me.
I'm still a little surprised that the human economy encompasses as much as
98% of chordata, although a figure in the 10s of percent wouldn't
surprise me. We still have quite a lot of wild vertebrate fauna here
in Australia, and even in the more densely populated parts of the
world, rattus rattus must represent a substantial portion of the biomass.
Unless he's also including species that happen to thrive because of
humans...
