Contribu)on of traits, phenology, & phylogene)c history to plant-‐
pollinator network structure Sco; Chamberlain Simon Fraser University
Thanks to! • Elizabeth Elle • Jana Vamosi

Species level metrics • Degree • Specializa)on (accounts
for interac)on intensity) • Within module degree • Among module connec)vity
Traits -‐ Pollinators • Nest loca)on: above/below ground -‐
NS • Nest type: excavator/renter -‐ NS • Parasi)c: yes/no -‐ NS
Traits -‐ Pollinators • Nest loca)on: above/below ground -‐
NS • Nest type: excavator/renter -‐ NS • Parasi)c: yes/no -‐ NS • Social: solitary/social – – Within module degree: social (module hubs), solitary (peripherals) – Among module connec)vity: social (connectors), solitary (peripherals) – Degree: social (higher), solitary (lower) • Body size – larger spp. w/ larger degree
Traits -‐ Plants • Breeding system –
Gynomonoecious: less specialized, higher degree – Hermaphrodites: more specialized, lower degree
Traits -‐ Plants • Breeding system –
Gynomonoecious: less specialized, higher degree – Hermaphrodites: more specialized, lower degree • Growth form – Herbaceous: lower within module degree – Woody: higher within module degree
Traits -‐ Plants • Breeding system –
Gynomonoecious: less specialized, higher degree – Hermaphrodites: more specialized, lower degree • Growth form – Herbaceous: lower within module degree – Woody: higher within module degree • Flower symmetry: – Bilateral: lower within module degree, lower degree – Radial: higher within module degree, higher degree • Flower size: smaller flowers higher within module degree

Conclusion • Species level – Sociality important in pollinators
– Ma)ng systems, flower symmetry & growth form important in plants • Network level – At network level, é pollinator func)onal diversity w/ é modularity & ê connectance – Pollinator traits bigger drivers of network structure rela)ve to plants
Phenology • Species vary in when they start flowering
(plants) and start flying (pollinators) • Varia)on among species can lead to changes in network structure

Phylogene)c tree shape • Shape easily measured •
Metrics represent whether – Branching events recent or old – Branching events even across tree, or some groups speciate more than others • Shape could influence who interacts with who
