Pollination networks
During the flowering season (October–February) we identified all plant species pollinated by animals in each site and estimated the rate of flower visits. To this end, we conducted 10 min censuses per plant where we recorded the identity, number of pollinator visits, and number of flowers per individual or branch visited (when the sample plant has a large number of flowers). A visit was recorded when the visitor touched a reproductive structure of the flower. Pollinator species that could not be identified in the field were collected and identified in the laboratory. We performed the censuses from 11:00 to 17:00 h in sunny, non-windy days. We carried out at least 12 censuses per plant species. We conducted 2277 observation periods for all sites and plant species in 2017-2018, and 2269 observation periods in 2018-2019. These numbers varied across species and sites because species differed in their abundance, duration of flowering period and flower production (See Table S1 in Supporting Information).
