  abstract = {{P}lant phenology is concerned with the timing of recurring biological events. {T}hough phenology has traditionally been studied using intensive surveys of a local flora, results from such surveys are difficult to generalize to broader spatial scales. {I}n this study, contrastingly, we assembled a continental-scale dataset of herbarium specimens for the emblematic genus of {N}eotropical pioneer trees, {C}ecropia, and applied {F}ourier spectral and cospectral analyses to investigate the reproductive phenology of 35 species. {W}e detected significant annual, sub-annual and continuous patterns, and discuss the variation in patterns within and among climatic regions. {A}lthough previous studies have suggested that pioneer species generally produce flowers continually throughout the year, we found that at least one third of {C}ecropia species are characterized by clear annual flowering behaviour. {W}e further investigated the relationships between phenology and climate seasonality, showing strong associations between phenology and seasonal variations in precipitation and temperature. {W}e also verified our results against field survey data gathered from the literature. {O}ur findings indicate that herbarium material is a reliable resource for use in the investigation of large-scale patterns in plant phenology, offering a promising complement to local intensive field studies.},
