2.4.1. Insect availability
We averaged insect mass over the seven visits across sampling locations
within a home range and summed all sampling locations per site to get a
single measure of insect order biomass per site. We used Mann-Whitney U
to determine differences (P = 0.05) in insect abundance between sites
occupied by GFWO and unoccupied sites, and used Spearman’s Rho to test
for significant correlations between each insect order’s biomass and
each male GFWO’s home range size (Field et al., 2012).
