A paper by Jessica Blois, Jack Williams, and co-authors is now available online early at Ecography (link). This paper paired fossil pollen assemblages across eastern North America from the Neotoma database with paleoclimatic simulations to model the climatic drivers of fossil pollen dissimilarity across space over the past 21,000 years. We found that the set of climate variables associated with dissimilarity between fossil pollen assemblages across eastern North America changed over the past 21,000 years. Higher magnitudes of climate change between time periods meant lower prediction strength when projecting spatial models of community dissimilarity to different time periods.
