Fig 1.
The plant-pollinator network according to encounter-based (top) and visit-based (bottom) measures of interaction strength.
Pollinator species in orange, plant species in green. Width of horizonal bars denotes interaction frequency of each species. Gray bar width denotes interaction strength. See Table 1 for plant species.
Table 1.
Number of pollinator species, mean ± SD number of visits per encounter (mean of all pollinator species) and floral display (mean number of open flowers at peak bloom) for each plant species surveyed.
Fig 2.
Relationship between mean number of visits per encounter (log-transformed) and floral display (log-transformed) (p = 0.0005; R2 = 0.49; n = 19 plant species).
Shaded areas denote 95% confidence interval. See Table 1 for plant species names.
Fig 3.
Relationship between encounter-based and visit-based measures of three species descriptors (species strength, push-pull index and d’ specialization index) for plants (a, c, e) and pollinators (b, d, f). Shaded areas denote 95% confidence intervals. Grey lines indicate slope = 1.
Fig 4.
Relationship between the magnitude of the change (ratio of the visit-based value divided by encounter-based value) of three species descriptors (species strength, push-pull index and d’ specialization index) and floral display of plant species.
Shaded areas denote 95% confidence intervals.
Table 2.
Descriptors of the original encounter-based and visit-based networks and of the networks obtained through bootstrapping (random subsamples of 25, 50 and 75% of the original interactions) (mean ± SD, n = 100).
P-values of paired t-tests comparing encounter- and visit-based subsampled networks are shown.
