Data from: Wind dispersal is predicted by tree, not diaspore, traits in comparisons of neotropical species

Description of Data and R code FilesThis file contains meta information of the four data files and one file with R scripts used for data analysis and making Figures.Data File 1. Diaspore traitsFor each of the study's tree species, mass, area, and descent rate for 15 individual diaspores.Data File 2. Measured dispersal distancesFor each of the study's tree species, the number of seeds found at each distance, measured in transects from the parent trunk (all transects combined).Data File 3. Parent tree informationFor each of the study's tree species, information of location, DBH, maximum height, median height, crown area, crop size, and seed shadow area of the tree.Data File 4. Transect dataFor each of the study's tree species, the number of seeds found in each quadrat at each distance in each of six (eight) directions from the parent trunk. Area of quadrat is provided.File 5. R scriptsR scripts 1) to make Figures 2 and 5; 2) to fit alternative models to explain variation among diaspores in the rate of descent in still air (results from this analysis are in Tables 2 and 3); and 3) to fit alternative models to explain variation among species in seed shadow characteristics using tree and diaspore traits (results from this analysis are included in Tables 4 and S11).

数据文件与R代码文件说明
本文档包含本研究所用的4份数据文件及1份用于数据分析与绘图的R脚本文件的元信息。
1. 传播体性状数据：针对本研究中的各乔木树种，每份样本包含15个独立传播体（diaspore）的质量、面积与沉降速率。
2. 实测传播距离数据：针对本研究中的各乔木树种，统计了自母树树干出发的所有合并样带中，各距离区间内发现的种子数量。
3. 母树信息数据：针对本研究中的各乔木树种，包含母树的位置、胸径（DBH, diameter at breast height）、最大树高、中位树高、冠幅、结实量以及种子扩散区面积等信息。
4. 样带数据：针对本研究中的各乔木树种，统计了自母树树干出发的6（8）个方向上，各距离区间内每个样方内发现的种子数量，并提供了样方面积信息。
5. R脚本文件：本R脚本包含三项功能：① 绘制图2与图5；② 拟合备选模型以解释静风环境下传播体沉降速率的个体间变异（该分析结果详见表2与表3）；③ 拟合备选模型以基于母树与传播体性状解释不同树种的种子扩散区特征差异（该分析结果详见表4与附表S11）。
