Abstract: Increasing human activity across the globe has resulted in large shifts in the biotic and abiotic conditions that species encounter. Along these lines, climate change and the displacement of species beyond their native ranges represent some of the largest threats to biodiversity that characterize the Anthropocene. Here we examine how the timing of plant reproduction (i.e., reproductive phenology) responds to changes in climate, and how variations in these responses may manifest across species ranges using data from herbarium collections and citizen science initiatives. We demonstrate that phenological responses to climate change will be heterogeneous within communities and across regions, with large amounts of regional variability driven by local adaptation, phenotypic plasticity, and differences in species assemblages. We also show how the phenological and phylogenetic similarity between native and introduced species may influence the outcome of biological invasions. Our work highlights the utility of natural history collections in revealing large-scale patterns within assemblages and across landscapes that ultimately can improve our understanding of how plant communities may respond to continued global change.
