Height Data

These are height measurement data for female, individually-known African elephants in the Samburu and Buffalo Springs National Reserves. These data were used in the manuscript "Orphaning stunts growth in African Elephants", currently under review. The first Excel worksheet is titled "GW.growth.curve". It shows the median of the height measurements taken from an elephant on a single date by author George Wittemyer. These medians were used to create a von Bertalanffy growth curve upon which we structured the Bayesian analysis that addressed our main hypotheses. The second worksheet titled "All.data" shows all measurements taken by either author. The third worksheet shows a summary of author Jenna Parker's measurements, including which individuals were not included in the main analysis because we are unsure of their exact birthdate.本数据集涵盖桑布鲁与布法罗斯普林斯国家保护区（Samburu and Buffalo Springs National Reserves）内个体身份明确的雌性非洲象的身高测量数据。本数据集曾被用于目前处于审稿阶段的论文《非洲象的孤儿身份抑制生长》（Orphaning stunts growth in African Elephants）。首个Excel工作表命名为"GW.growth.curve"，展示了作者George Wittemyer针对单只大象单日采集的身高测量数据的中位数；该组中位数被用于构建冯·贝塔朗菲生长曲线（von Bertalanffy growth curve），我们依托该曲线开展了针对核心研究假设的贝叶斯分析（Bayesian analysis）。第二个工作表命名为"All.data"，收录了两位作者获取的全部测量数据。第三个工作表汇总了作者Jenna Parker的测量结果，其中包含因无法确定准确出生日期而未纳入主分析的个体信息。

背景概述

该数据集包含非洲雌性象（个体已知）的身高测量数据，来自Samburu和Buffalo Springs国家保护区，用于研究'孤儿象生长受阻'的论文分析。数据集由三个Excel工作表组成，分别提供身高中位值（用于生长曲线建模）、所有原始测量值和测量总结，其中部分个体因出生日期不确定被排除在主要分析外。
