code R Zapelini_etal_2022.docx

Code used to calculate functional diversity metrics applied to sites in marine protected areas in the south of the state of Bahia, Brazil. Abundance data was used. <br> A significance test was implemented: Generate sites with random abundance values keeping randomization only between rows (spp). In this way, the relative abundance of sp1 will be exchanged between sites. <br> Standardized effect size (SES) for each index and each site in order to verify the amount of deviation of the observed indices of the real assemblages in relation to the indices of the simulated sites. <br> Results for each index are plotted

本代码用于计算巴西巴伊亚州南部海洋保护区样点的功能多样性指标，研究采用了物种丰度数据。<br>本研究实施了显著性检验：生成带有随机丰度值的样点，且仅在行（物种，spp）层面开展随机化操作。通过该方式，物种sp1的相对丰度将在各样点间进行交换。<br>针对各指标与各样点计算标准化效应量（Standardized Effect Size, SES），以此验证真实群落观测指标相较于模拟样点指标的偏离程度。<br>针对各指标的计算结果将进行可视化绘图。
