Supplement 1. Treatment means and standard errors for densities and biomass of community members at the end of the experiment, categorized by taxa.

File List species.csv (MD5: a18a08d0fa52e0e4ade0a906fe5058b2) Description The species.csv is a tab separated file. It contains the mean and standard error for the absolute density and dry biomass (in mg) of each animal taxa within ponds for a given predator size treatments. Column definitions Taxa (grouped by order and family) Mean densities for Control treatment Standard error of densities for Control treatment Mean densities for small Anax treatment Standard error of densities for small Anax treatment Mean densities for medium Anax treatment Standard error of densities for medium Anax treatment Mean densities for large Anax treatment Standard error of densities for large Anax treatment Mean biomass for Control treatment Standard error of biomass for Controltreatment Mean biomass for small Anax treatment Standard error of biomass for small Anax treatment Mean biomass for medium Anax treatment Standard error of biomass for medium Anax treatment Mean biomass for large Anax treatment Standard error of biomass for large Anax treatment Rows 89–96 provide additional information on individual taxa groups.
