Subject: Summary: bootstrap in conservation biology
Here is a compilation of replies to my recent request for papers in
conservation biology that use bootstrap procedures and that could be
used as individual student work in a block course on statistical
ecology. I checked some of the papers and thus added some comments.
Hope that will be of use to somebody.
Regards, Christian.

I checked both: they rely on data from earlier papers (which I havn't
located yet, french libraries are a mess ;-) which should be
available in any good (US) library. Bootstrap is used in several ways
and (based on the original data) students could easily recompute one
or two of the analyses and thus get a better understanding of the
whole paper (in my case they would have to do this in Matlab and
prepare a summary presentation of the paper, the method and the
results: estimated time approx 3 days).
