Schematic network, serving as an instructive example of our method for classifying the faculty

, their pollinator coauthors

, and the links between them. The network corresponds to the table on the right. Two types of links connect the faculty nodes: a direct link (

) if

and

are coauthors of at least one publication together, and a mediated link (

) if there is at least one

that has coauthored separately with

and

, thereby mediating a triadic closure between the two

. We classified each

according to her/his main discipline:

= biology and

= computing unless they have collaborated with at least one

from the other discipline, in which case the classification

supersedes their original disciplinary classification. We classified the non-

coauthors

as bridge pollinators if they coauthored with two or more faculty; otherwise, these

are classified as leaf pollinators. Among the bridge pollinators, we classified those

who coauthor with faculty from both biology and computing as cross-pollinators. Thus, the solid link connecting A-B represents a direct cross-disciplinary link, the dashed link connecting C-A represents a mediated cross-disciplinary link, and pollinators 7 and 8 are cross-pollinators because they have collaborated with faculty from each discipline.
