Fig S4 . Species-level relationships between generalization,
measured as degree (number of links), and A, B: number of years in which
species were recorded interacting, C, D: phenophase lengths, and E, F:
number of plots in which species were recorded interacting. Plant
phenophases are defined as the last (maximum) minus the first (minimum)
day of the year in which each species was recorded interacting with
pollinators, while pollinator phenophases are defined as the last minus
the first day of the year in which each species was recorded interacting
with flowers. Inter-annual persistence, longer phenophases, and higher
plot occurrence were associated with a higher degree. For both plants
and pollinators, species that had higher inter-annual persistence were
had a higher degree (A, B; for plants: R2 = 0.73, P
<< 0.001, for pollinators R2 =
0.61, P << 0.001). Both plant and pollinator species
with longer phenophases had a higher degree (C, D; R2= 0.70, P << 0.001, for pollinators
R2 = 0.56, P << 0.001). Both plant
and pollinator species that were more widespread among plots were closer
to the core of the nested network (E, F; R2 = 0.60, P
<< 0.001, for pollinators R2 =
0.57, P << 0.001). Blue shaded areas display 95%
CIs around means of model estimates.
