Connell Rainforest Plot Network: Longitudinal Variation in Seedling Recruitment in Eight Species, Davies Creek Plot, Dinden National Park, Queensland, Australia, 1965–2004

This data package shows longitudinal variation in seedling recruitment, the proportion of all recruits, and the corresponding number of standing seedlings for eight species of trees. These demonstrate that there is considerable variation in seedling recruitment across both species and time. These data are used to produce the graphs found in figures 5.18 on page 141.

This plot consists of one 1.7 hectare plot in tropical rainforest, established in 1963. Rainforest tree attributes recorded comprise the size (height or girth) of tagged and mapped, free-standing stems of shrub and tree species. Sampling has been undertaken at intervals of 1-6 years since 1963, and this data package describes longitudinal variation in seedling recruitment over almost four decades. This data package forms part of the collection of vegetation data undertaken at plots situated in both Lamington National Park and Davies Creek initiated by Professor Joseph H. Connell (University of California, Santa Barbara) in 1963. A synopsis of related data packages which have been collected as part of the Connell Rainforest Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/connell-rainforest.

本数据集展示了8个树种的幼苗更新（seedling recruitment）动态、总更新个体占比，以及对应现存幼苗数量。研究结果表明，不同树种间以及不同时间尺度下，幼苗更新均存在显著差异。本数据集用于绘制第141页图5.18中的相关图表。

本研究样地为1963年设立的热带雨林1.7公顷固定样地。本次采集的雨林乔灌物种属性，包括已标记并测绘定位的独立植株的大小（高度或胸径）。自1963年起，研究团队以1-6年为间隔开展周期性采样，本数据集完整呈现了近40年间的幼苗更新动态变化。本数据集是1963年由加州大学圣巴巴拉分校的Joseph H. Connell教授发起的、针对拉明顿国家公园（Lamington National Park）和戴维斯溪（Davies Creek）两处样地的植被数据采集项目的组成部分。康奈尔热带雨林样地网络（Connell Rainforest Plot Network）完整项目所采集的相关数据集概览，可通过以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/connell-rainforest。
