Trees as indicators of past climates and forest dynamics in Central Canada

研究重点是环境因素（例如，气候、昆虫、疾病、火灾）影响树木生长和年轮形成。在加拿大，树木每年都会产生年轮，并且通常可以存活几个世纪。因此，我们可以利用它们或它们的年轮特征来重建仪器记录之前的条件。例如，这种能力使我们能够获得欧洲人定居之前的气候变化信息。然而，要做到这一点，我们需要清楚地了解当今的环境条件如何影响各种物种和栖息地的树木生长。这项研究从研究木材解剖到量化昆虫爆发，森林火灾和极端气候等大规模现象的影响。树木年轮研究不仅可以更好地了解生长情况，而且还可以预测人类活动和/或自然变化带来的未来环境变化可能对加拿大人及其环境产生的影响。这项研究主要集中在加拿大中部。

The research focuses on how environmental factors (e.g., climate, insect, disease, fire) affect tree growth and tree-ring formation. In Canada, trees produce annual tree rings and often live for many centuries. We can thus utilize them or their tree-ring characteristics to reconstruct conditions prior to recording by instruments. This capability allows us for example to gain information on climate variability prior to European settlement. To do so however, we need a clear understanding of how today's environmental conditions affect tree growth in various species and habitats. This research goes from studying wood anatomy to the quantification of the impact of large scale phenomena like insect outbreaks, forest fires, and climate extremes. Tree-ring research not only allows for a better understanding of growth but it also allows to foresee how future environmental changes brought by human activities and/or natural variations may impact Canadians and their environment. This research mainly focuses on central Canada.
