Southern post-glacial migration-rate estimates (m yr<sup>–1</sup>) assuming that species spread to their present-day northern limit from the south (40–45°N latitude), and northern migration rates assuming that species spread to their present-day northern limit from their northernmost refugia.

资源简介:

Estimated rates of migration assuming no movement of taxa during the two major cold periods: Heinrich Event1 (lasting ∼4000 years) and the Younger Dryas (lasting ∼1000 years) are given in italics. Projected mean migration rates (m yr–1) for several tree species for 2100 using B1/SEDG greenhouse gas emission/land-use change scenarios, as well as the maximum rates derived from weak competition and optimum temperature conditions [31] are also given. When no exact species name is available in the fossil record the genus name is used.
