title: Data from: Climate change increases flowering duration, driving phenological reassembly and elevated co-flowering richness

description: Changes to flowering phenology are a key response of plants to climate
 change. However, we know little about how these changes alter temporal
 patterns of reproductive overlap (i.e., phenological reassembly). We
 combined long-term field (1937-2012) and herbarium records (1850-2017) of
 68 species in a flowering plant community in central North America and
 used a novel application of Bayesian quantile regression to estimate
 changes to flowering season length, altered richness and composition of
 co-flowering assemblages, and whether phenological shifts exhibit seasonal
 trends. Across the past century, phenological shifts increased species’
 flowering durations by 11.5 d on average, which resulted in 94% of species
 experiencing greater flowering overlap at the community level. Increases
 to co-flowering were particularly pronounced in autumn, driven by a
 greater tendency of late-season species to shift the ending of flowering
 later and to increase flowering duration. Our results demonstrate that
 species-level phenological shifts can result in considerable phenological
 reassembly and highlights changes to flowering duration as a prominent,
 yet underappreciated, effect of climate change. The emergence of an autumn
 co-flowering mode emphasizes that these effects may be season-dependent.
