植被对过去气候变化的反应为植被对未来气候变化的反应提供了重要的见解。预测未来的一个关键问题是获得植物随着环境变化而能够传播的速度的估计。为了解决这种不确定性，我们回顾了古生态和系统地理文献，以估计观察到的欧洲主要树木的蔓延速度范围，并讨论它们在冰川后蔓延的各个方面。在欧洲花粉数据库提供的花粉图中，用等时线图描述了花粉比例达到特定阈值的时间。我们发现，早期殖民者包括松树和榆树，实现了至少1000m年−1的速率，而后来扩展到成熟林地，如栎树和梧桐的树木，实现了约500m年−1的速率。对大多数丰富的欧洲树木进行了系统地理研究，经常表明，南欧三个半岛中部和南部的种群不是冰川后中欧和北欧殖民的起源。在某些情况下，这些研究的结果清楚地显示了冰后传播的方向，同时通常提供了有助于解释花粉数据的新信息。阿尔努斯的系统地理结果表明，冰后高的表观扩散速度是由于在低人口密度下的初始扩散和后来的扩张。这种扩散和种群扩张之间的脱钩现象也见于后期扩张的树木，如云杉、水曲柳和龙须草。在这里，人口扩张很可能不是因为扩散而推迟，而是像冯·波斯特假设的那样，是由于气候限制。虽然瑞典的Picea和Fagus在全新世晚期的扩张在100年前冯·波斯特的花粉分析发展中作为一种测年工具是重要的，但我们仍然无法确定是哪一种特定的驱动因素导致了这两棵树的后期扩张。
The reaction of vegetation to past climate change provides important insights for vegetation responses to future climate change. A key problem for projections into the future is obtaining estimates of the rates at which plants are able to spread as their environment changes. To address this uncertainty, we review the palaeoecological and phylogeographic literature to estimate the range of observed rates of spread for the major European trees and discuss aspects of their postglacial spread. The review is illustrated with isochrone maps depicting the time when particular thresholds in pollen proportion were reached in pollen diagrams available from the European Pollen Database. We find that rates of at least 1,000 m year−1were realised by early colonisers includingCorylusandUlmus, while trees spreading later into established woodlands, e.g.QuercusandTilia, achieved rates of around 500 m year−1. Phylogeographic investigations are available for most of the abundant European trees, often indicating that populations in the central and southern parts of the three south European peninsulas were not the origins for the postglacial colonization of central and northern Europe. In some cases, the results of these studies clearly show the direction of postglacial spread, while generally providing new information to help in interpreting pollen data. Phylogeographic results forAlnussuggest that the high apparent rates of postglacial spread are due to an initial spread at low population density and a later expansion. This decoupling between spread and population expansion is also seen for late expanding trees such asPicea, FagusandCarpinus. Here, population expansion was probably not delayed by dispersal, but by a limiting climate as assumed by von Post. While the late Holocene expansion ofPiceaandFagusin Sweden was important as a dating tool in the development of pollen analysis by von Post 100 years ago, we remain unable to determine which particular driver caused the late expansion of these two trees.
