Resumen:
Morphology and phenology influence plant?pollinator network structure, but whether they gener-ate more stable pairwise interactions with higher pollination success remains unknown. Here weevaluate the importance of morphological trait matching, phenological overlap and specialisationfor the spatio-temporal stability (measured as variability) of plant?pollinator interactions and forpollination success, while controlling for species? abundance. To this end, we combined a 6-yearplant?pollinator interaction dataset, with information on species traits, phenologies, specialisation,abundance and pollination success, into structural equation models. Interactions among abundantplants and pollinators with well-matched traits and phenologies formed the stable and functionalbackbone of the pollination network, whereas poorly matched interactions were variable in timeand had lower pollination success. We conclude that phenological overlap could be more usefulfor predicting changes in species interactions than species abundances, and that non-randomextinction of species with well-matched traits could decrease the stability of interactions withincommunities and reduce their functioning.
