Lagged climate-driven range shifts at species’ leading, but not trailing, range edges revealed by multispecies seed addition experiment

Climate change is causing many species' ranges to shift upslope to higher elevations as species track their climatic requirements. However, many species have not shifted in pace with recent warming (i.e., ‘range stasis’), possibly due to demographic lags or microclimatic buffering. The ‘lagged-response hypothesis’ posits that range stasis disguises an underlying climatic sensitivity if range shifts lag the velocity of climate change due to slow colonization (i.e., colonization credits) or mortality (i.e., extinction debt). Alternatively, the ‘microclimatic buffering hypothesis’ proposes that small-scale variation within the landscape, such as canopy cover, creates patches of suitable habitat within otherwise unsuitable macroclimates that create climate refugia and buffer range contractions. We simultaneously test both hypotheses by combining a large seed addition experiment of 25 plant species across macro- and micro-scale climate gradients with herbaria records to compare patterns ..., , , # Data from: Lagged climate-driven range shifts at species’ leading, but not trailing, range edges revealed by multispecies seed addition experiment
