[ECOLOG-L] pitfall trap sampling of arthropods to detect size effect

[Bracha Schindler]

We are conducting an experiment with different sized plots (0.25, 1, 4, and
16 square meters) and would like to determine if plot size has an effect on
arthropod diversity using pitfall traps. It wouldn't be feasible to have
the number of traps proportional to plot size, as that would mean 64 traps
in the largest plots. We are looking for suggestions for a sampling design
that will capture the plot effect size with a smaller number of traps per
plot.
Thanks,
