New food-web model

Dear Colleagues,

I am a bit worried that I was too sharp in the description of the
mailing list about the "signal-to-noise ratio".  It was not meant to
discourage your contributions.  

On the contrary, I really think that progress in our field is at least
partially limited by an imperfect flow of information and the
resulting differences in perspectives.  This is a pity, because
food-webs science could contribute a lot more to urgent questions
related to biodiversity, invasive species, and fisheries, and also
fundamental problems of macroecology, than it currently does.  The
field has a lot more to offer, and is certainly large enough to
provide a comfortable niche for all of us.

Please tell us about your latest results!

Hoping that you do not experience this contribution as "noise", I
would like to bring your attention to a manuscript of us on

      "The top-down mechanism for body mass -- abundance scaling"

(http://axel.rossberg.net/paper/Rossberg2007b.pdf), recently accepted
for Ecology.

The Appendix of the paper describes a new evolutionary food-web model
which is probably the most complex, but perhaps also the most
realistic available so far.  Copy-right issues pending, the code of
