Woods from a Tropical Forest Region (Peru) as Climate Indicators and Development of a Preliminary Model for Reconstructing Climates Based on Fossil Wood

摘要ATM-9707899伍德科克，夏威夷黛博拉大学标题：来自热带林区(秘鲁)的木材作为气候指标和基于化石木材化石木材重建气候的初步模型的开发具有很高的潜力来产生关于过去气候的信息，并可能被证明是特别重要的，作为大陆内陆气候的记录，那里几乎没有发现其他类型的植物遗骸。化石木材还可以提供独立于树叶外貌和其他气候指标的环境信息；而且可能是有关过去降水变异性的重要信息来源。然而，我们对气候影响木材结构的方式的有限理解阻碍了对气候的解释。该奖项支持一个项目，该项目旨在研究湿润和山地热带森林树木的木材，并建立一个将气候与木材特征联系起来的数据库。该项目将把用来描述木材的特征系统化，特别是容器的大小和分布，这已被证明能显示气候敏感性；并将森林/气候类型的木材与世界其他地方的数据进行比较，以确定那些最有希望作为气候指标的特征。这项工作还将开发一个表达木材：气候反应的多变量模型，该模型将允许对化石木材进行详细的定量气候估计重建。

Abstract ATM-9707899 Woodcock, Deborah University of Hawaii Title: Woods from A Tropical Forest Region (Peru) as Climate Indicators and Development of a Preliminary Model for Reconstructing Climates Based on Fossil Wood Fossil wood has a high potential to yield information about past climates and may prove to be particularly important as a record of climates in continental interiors where few other types of plant remains are found. Fossil wood can also provide environment information independent of leaf physiognomy and other climate indicators; and maybe an important source of information about past precipitation variability. Climate interpretations are hindered, however, by our limited understanding of the way in which climate affects wood structure. This award supports a project designed to examine woods from wet and montane tropical forest trees and to construct a database relating climate to wood characteristics. The project will systemize the characters used to describe wood, particularly vessel size and distribution, which have been shown to display climate sensitivity; and compare of woods from forest/climate types to data from elsewhere in the world to identify those characters most promising as climate indicators. This work will also develop a multivariate model expressing the wood:climate response that will permit detailed reconstruction of quantitative climate estimates to be carried out on fossil wood.
