Abstract

ABSTRACT We present the longest tree-ring chronology to date in northeastern North America (2233 years; 227 BCE – 2005 CE), resulting from several research projects conducted at the subarctic treeline in northern Quebec. This raw chronology of tree-ring width includes 464 black spruce (Picea mariana (Mill.) B.S.P.) shrubs (krummholz) growing in wetlands and preserved within peatlands. An indexed series of 152 erect black spruce trees that have lived in wetlands is also presented, covering the period 216 BCE to 1619 CE. We compared these chronologies to a tree-ring series including 116 black spruce trees and krummholz having grown on well-drained lichen woodlands over the period 1304–2000 CE. These chronologies highlight the major climatic periods of the last two millennia. Floating chronologies dating from 2500 to 3500 years ago were also developed from trees preserved in frozen peat. Growth rings from this period are much wider than those of the last 2233 years, suggesting warm climatic conditions and permafrost-free peatlands during the transition from mid- to late Holocene. The three subarctic chronologies presented here underscore the relevance and usefulness of tree growth rings and growth forms as ecological tools to assess the influence of climate on subarctic ecosystems.
亚北极黑云杉2233年年轮年代学:生长形式对长期气候变化的响应
摘要:我们提出了北美东北部迄今为止最长的树木年轮年表(2233年;公元前227年–公元前2005年),这是在魁北克北部亚北极树木线上进行的几个研究项目的结果。树木年轮宽度的原始年表包括464株生长在湿地并保存在泥炭地内的黑云杉(Picea mariana(Mill.)B.S.P.)灌木(krummholz)。还介绍了一个由152棵生活在湿地中的直立黑云杉树组成的索引系列,涵盖了公元前216年至公元前1619年。我们将这些年表与一个树木年轮系列进行了比较,该系列包括公元1304年至2000年期间生长在排水良好的地衣林地上的116棵黑云杉和克鲁姆霍尔茨。这些年表突出了过去两千年的主要气候时期。2500年至3500年前的浮动年表也是由保存在冷冻泥炭中的树木发展而来的。这一时期的生长环比过去2233年的生长环要宽得多,这表明在全新世中期到晚期的过渡时期,气候条件温暖,泥炭地没有永久冻土。这里介绍的三个亚北极年表强调了树木生长环和生长形式作为评估气候对亚北极生态系统影响的生态工具的相关性和有用性。
