Supplementary Material 1: Resource diversities, conspecific densities, and heterospecific
densities for each species at each pond. When calculating these resource diversities, we
used arthropods collected at all locations for both toad species and for L. sphenocephalus,
but for L. catesbeianus and L. clamitans we used only the arthropods collected up to 30m
from ponds because these frog species were never found further than 30m from a pond.
Conspecific density was measured as the average number of frogs seen per 20 minute
scan search divided by the area of the pond. For L. catesbeianus and L. clamitans, which
rarely overlapped spatially with the two toad species, we calculated heterospecific density
by subtracting conspecific density from the total density of L. catesbeianus, L. clamitans,
and L. sphenocephalus. For both toad species, A. americanus and A. fowleri, we obtained
heterospecific densities by subtracting conspecific density from the total density of A.
americanus, A. fowleri, and L. sphenocephalus. To obtain heterospecific densities for L.
sphenocephalus, which overlapped spatially with all four other study species, we totaled
the density of all frogs and toads and subtracted L. sphenocephalus density.
