The Functional Consequences of Mutualistic Network Architecture
Figure 2
Pollinator effects on network topology.
a) Expected changes in network connectivity due to different functional groups of pollinators. Network graphs are depicted for three example populations, illustrating the relationships among individual plants when all pollinator species are included (left) and when only specific subsets are considered (right). Note how the “hub” plants spread all over the partial networks. b) Differences among pollinator type (from left to right, beeflies, beetles, hoverflies, bees and butterflies) in hub degree (F4,16 = 21.83, P = 0.0001) and functional specialization (F4,16 = 4.13, P = 0.036).
