Living in synchrony on Greenland coasts?

摘要

Theory indicates that correlated weather may synchronize populations1, but the extent to which this holds for non-identical, nonlinear systems is uncertain. Post and Forchhammer2 claim to have shown climate-induced synchrony for musk oxen and caribou that are separated by the Greenland ice sheet. However, logical and mathematical errors undermine their finding. Whether or not large-scale weather can be a major synchronizing factor across species remains an open question. (Journal)
