Slope of SAR in 15-yr windows

As part of a sensitivity analysis, the slope of the species-area relationship was calculated for mesopredator and prey trophic groups across the banks in 15-yr sliding windows. This revealed temporal trends consistent with the pre-1992 and post-1991 analysis in the main text. See Supplementary material for details.作为敏感性分析（sensitivity analysis）的一部分，本研究针对沿各岸带分布的中型捕食者（mesopredator）与猎物营养类群，在15年滑动窗口（15-year sliding windows）下计算了物种-面积关系（species-area relationship）的斜率。该分析所揭示的时间趋势与正文中1992年前及1991年后的分析结果保持一致，详细内容请参见补充材料。
