Longspined sea urchin size and movement metrics (data accompanying: "The risky nightlife of undersized urchins")

This data package consists of two files to accompany the manuscript Smith J., Flukes E., Keane J.P. (2024) The risky nightlife of undersized sea urchins. Marine and Freshwater Research IN PRESS.Dataset A: 211 Centrostephanus rodgersii (longspined sea urchin) were measured for test diameter and spine canopy at Fortescue Bay, Tasmania, Australia in May-June 2023 (FB_TD_SC.csv)Dataset B: Urchin movement data from Flukes et al. 2023 and associated urchin sizes measured in this study (whole_measured_df.csv)

本数据包包含两份配套文件，用于配合Smith J.、Flukes E.、Keane J.P.（2024）发表于《Marine and Freshwater Research》（已付印）的论文《体型偏小的海胆的风险夜间活动行为》。数据集A：2023年5至6月，研究人员于澳大利亚塔斯马尼亚州福斯克湾（Fortescue Bay），对211头长棘海胆（Centrostephanus rodgersii）的壳径（test diameter）与棘冠（spine canopy）进行了测量，对应数据文件为FB_TD_SC.csv。数据集B：包含Flukes等人2023年的海胆移动数据，以及本研究中实测的对应海胆尺寸数据，对应数据文件为whole_measured_df.csv。
