If you have, or know of, examples like this, I would appreciate hearing from
you, and will gladly
explain what we are trying to do.

small magnitude, which makes it perhaps not interesting. Your damaged plot may
have high
autocorrelation values, but not be 'significant' merely because of low sample
size. You should
always report both the statistical tests and the effect sizes.

What you need is a goodness-of-fit test for homogeneity. The most well-known
goodness-of-fit
test is the Chi-square. A somewhat better one is the G test. Both are described
in Sokal and Rohlf.
In tests for homogeneity, your 'null hypothesis' is given by the proportions of
the various species
think might be interested.

Louise,
Most people get these papers from Foundations of Ecology (ed. Leslie Real). I'm
impressed if you
found the originals!
Foundations is divided into sections of a few papers each, and there is an
introduction to each
section that places the papers in historical and current context. Might

difficulties with having 58-parameters! Having said that, 16 parameters is a
lot as well, so, without
knowing anything about your model, you might want to look for redundancy,
and/or try to reduce
your number of parameters with PCA or some other technique.

Volker,
The fundamental difficulty you face is that the best quality cameras are
