Abstract

The authors compared uninvaded and invaded ecological communities, to examine how two species of invasive plants with large and showy flowers (Carpobrotus affine acinaciformis and Opuntia stricta) affect the structure of Mediterranean plant–pollinator networks at the Natural Park of Cap de Creus, Catalonia

Methods

Datasets describe the frequency of visits observed for each pollinator-plant interaction. The study involved pollinator surveys in 3 sites per study species. Pairs of invaded and uninvaded plots were samples in all sites. Sites were sampled every 2 weeks during the entire flowering period of both C. affine acinaciformis and O. stricta. Each plant species was sampled during 6 minutes. Each species was sampled for a total of 36 minutes per site. In total, each site was surveyed by pollinators for more than 6 hours.
