Connectance was significantly higher in environment type 1 (lmer, χ 2 = 6.85, df = 1, p = 0.008); and the difference in NODF, a measure of nestedness, was borderline significant between the environments (lmer, χ 2 = 3.40, df = 1, p = 0.06).
The borderline significance may exemplify the need to investigate such effects on new experiments by comparing environments with more diversified flower types.
Environment Type 2 Regarding environment type 2, the number of visits throughout the entire experiment between treated (n = 676) and control group (n = 920) did not differ significantly (F 1,143 = 1.742, p = 0.188), although the difference observed between the two groups presents an interesting trend ( Figure 1 C, Supplementary Material; Figure S2A ).
