Warming-induced changes in seasonal priority effects drive shifts in community composition.

ABSTRACT: Shifting community assembly dynamics are an underappreciated mechanism by which warming will alter plant community composition. Germination timing (which can determine the order in which seedlings emerge within a community) will likely shift unevenly across species in response to warming. In seasonal environments where communities reassemble at the beginning of each growing season, changes in germination timing could lead to changes in seasonal priority effects, and ultimately community composition. We test this expectation by assembling mesocosms of 15 species in one of two orders-"ambient" assembly order or "warmed" assembly order-based on the order in which the constituent species germinated under ambient and warmed conditions. Community composition differed significantly between mesoco
