Table 1 Network metrics used to describe species-level generalisation and compositional differences in supported pollinator communities among plant species.

Species-level metric

Description

Citing references

i) Normalised Degree (ND)

The number of interaction partner species divided by total number of species in other trophic level

17,19

ii) Interaction Strength (ST)

Sum of partner species’ dependencies (proportion of visits to given plant species)

39

iii) Closeness Centrality (CC)

The proximity of individual nodes (species) to all other nodes within a network; species with high scores are important to many other species

18,19

iv) Betweenness Centrality (BC)

How individual nodes act as ‘connectors’, linking otherwise unconnected subsets (modules) of species

18,19

v) Functional Complementarity (FC)

The ecological distance between plant species’ pollinator assemblages
