“…However, less use has been made of the natural experiment provided by the Late Pleistocene glaciation event. Many studies have documented the changes in species distributions and the subsequent effect on community structure (Graham 1986;Graham & Grimm 1990;Overpeck et al 1992;Graham et al 1996;Jackson & Overpeck 2000;Williams et al 2001;Lyons 2003Lyons , 2005Jackson & Williams 2004;MacDonald et al 2008). Less attention has been paid to the species traits associated with range shifts (but see Roy et al 2002).…”

“…Much of the work done in the late Pleistocene of North America has shown that previous climatic regimes were characterized by communities that have no modern analogues (e.g. Overpeck et al 1992; Roy et al 1995;Graham et al 1996;Jackson et al 1997;Jackson & Overpeck 2000;Davis & Shaw 2001;Roy 2001;Williams et al 2001Williams et al , 2004Lyons 2003Lyons , 2005. Moreover, Williams et al (2001) demonstrated that non-analogue communities are found in regions of non-analogue climate.…”

Understanding and predicting how species' distributions will shift as climate changes are central questions in ecology today. The late Quaternary of North America represents a natural experiment in which we can evaluate how species responded during the expansion and contraction of the glaciers. Here, we ask whether species' range shifts differ because of taxonomic affinity, life-history traits, body size or topographic heterogeneity and whether the species survived the megafaunal extinction. There was no difference in range shifts between victims and survivors of the megafaunal extinction. In general, the change in the size of a species' range is not well correlated with any of the ecological or life-history traits evaluated. However, there are significant relationships between some variables and the movements of the centroids of ranges. Differences in the distances shifted exist among orders, although this is probably a result of body size differences as larger bodied species show larger shifts. Although there are a few exceptions, the distance that species shifted their range was weakly correlated with life-history traits. Finally, species in more topographically heterogeneous areas show smaller shifts than species in less-diverse areas. Overall, these results indicate that when trying to predict species range shifts in the future, body size, lifespan and the topographic relief of the landscape should be taken into account.

“…It has been proposed that the warming at the Paleocene/Eocene boundary was responsible for the opening of high-latitude migration routes and the exchange of mammalian faunas among Europe, North America, and Asia (Rose, 1981b;Maas et al, this issue). Plants are also capable of geologically rapid range change in the face of climatic shifts (e.g., Overpeck et al, 1992). However, if the sharp carbon isotope excursion near the end of the Paleocene was associated with a very rapid climate change (<10 3 yr ?)…”

“…Hall's Cave contains a large number of fossil leporids throughout, partially mitigating the problems associated with interpreting data from small samples. Additionally, the chronology indicates that the Hall's Cave deposit is a product of relatively continuous deposition over the last 20,000 years, during which large shifts in global climate and vegetation occurred over much of North America (e.g., Overpeck et al, 1992). This time span provides the chance to test the sensitivity of the leporid δ 13 C record to changes in vegetation.…”
