On 6943 focal plants of 19 Protea species on all sites (Protea acuminata, P. burchellii, P. coronata, P. compacta, P. cynaroides, P. eximia, P. laurifolia, P. lepidocarpodendron, P. longifolia, P. lorifolia, P. magnifica, P. mundii, P. nana, P. neriifolia, P. nitida, P. obtusifolia, P. punctata, P. repens, P. susannae) we measured flowering phenologies. On a subset of 2580 focal individuals we measured plant traits (plant size inflorescence size, cone mass, specific leaf area (SLA), and trunk length from the ground to the first branch), on 1717 focal individuals we measured seed set on 1333 focal individuals we counted pollinator visitation rate and on 850 focal individuals we harvested inflorescences to measure sugar nectar. We created trait-based neighborhood models and investigated spatial and temporal effects of floral resources (nectar sugar) provided by the Protea plants in the study sites on the seed set and pollinator visitation rate.

Mapping of Protea communities, measuring functional plant traits, phenology, demographic rates and pollinator visitation rate
We mapped 19 Protea species on 27 different sites with a highly precise dGPS; in total 127 990 Protea individuals. From 6943 Protea individuals we counted on up to three visits the number of inflorescenecs for all species. We measured different plant traits from 2580 individuals. We created trait-based models to predict the flowering phenologies for all Protea species. We measured seed set and pollinator visitation rate of 1717 and 1333 focal individuals in a core zone of 100x100m with a 10m buffer, respectively. We related seed set and pollinator visitation rate to neighbourhood analyses from individual-based maps. Neighbourhood analyses include different neighbourhood effects of floral resources (nectar sugar) weighted with species specific flowering phenologies. This spatiotemporal variation of nectar sugar form sugar landscapes at different spatial and temporal scales We used these sugar landscapes and created different neighbourhood effects of conspecific and heterospecific sugar resources on different spatial scales to analyse seed set and pollinator visitation rate.
