[2] A pollination network is two-modal, i.e., it includes only links connecting plant and animal communities.
[7] A study of three separate networks, all of which showed modularity, revealed that hub species were always plants and not the insect pollinators.
[7] There is substantial interest into the robustness of pollination networks to species loss and collapse, especially due to anthropogenic factors such as habitat destruction.
The structure of a network is thought to affect how long it is able to persist after species decline begins.
[10] Another study revealed that with the removal of the most common pollinator species, the network showed a drastic collapse.
