The timing of life history events is critical for individuals to access ephemeral or limited resources. The study of phenology has focused on individuals or species and largely ignored the influence of phenology on community assembly and ecosystem services. Much remains to be learned about how species-level responses scale up to affect ecological communities. In addition, phenological responses provide one of the strongest and most conspicuous biological signals of climate change. The consequences of these phenological shifts depend on the fidelity and persistence of species interactions, yet we know surprisingly little about the information species use to coordinate life histories. From pollination to herbivory, the phenology of species interactions and communities will have important implications for population viability, invasive species management, and ecosystem function. This session brings together a diverse set of researchers to address the general topic of community phenology. The specific topics that will be explored rely on field experiments and observations, modeling, and biogeography to advance our understanding of how phenology shapes communities, and how communities will be affected by phenological shifts. Study systems span a range of taxa and focus on a variety of species interactions, giving a broad overview on the timing of life history events in a community context.
