Weak links between rainfall and semiarid grasslands can occur in the literature, making it difficult to forecast climate-induced community shifts. These weak links are perplexing given what we know is true about water-limited systems and plant growth. Here we delve further into the intricacies of rainfall events to uncover the surprising impacts of lagged rainfall in annual systems. We find that by rethinking rainfall events we can begin to identify complex pathways that are integral for shaping community composition across time. Precipitation lags may even alter the way we think about major drivers of change in semiarid systems.
