Effect of incorporating trophic level information and different weightings on average proportion of predator species per planning unit in chosen area. Average proportion of predator species for all planning units is indicated by orange line; Average proportion of predator species in chosen areas is shown for each target in runs without trophic information and for each target and weighting in runs with trophic information. Proportion of predator species for each target of runs without trophic information are drawn with thicker, solid lines and over all weightings, although no weighting was performed, to illustrate the difference between runs with trophic information, which are drawn with thinner, dashed lines. Trophic weighting is ratio highest to lowest with 3 being a weighting of 0.3-1, 4 being 0.25-1, 5 being 0.2-1, 6 being 0.15-1, 10 being 0.1-1, 20 being 0.05-1 and 100 being 0.01-1. a indicates significant difference (p <0.001) between scenarios with the same target.纳入营养级（trophic level）信息与不同权重方案对选定区域内各规划单元（planning unit）平均捕食者物种（predator species）占比的影响。橙色线条代表所有规划单元的捕食者物种平均占比；未纳入营养级信息的模拟实验中，各保护目标（target）对应的选定区域捕食者物种平均占比均有展示；纳入营养级信息的模拟实验中，各保护目标与权重组合下的该占比亦同步呈现。未纳入营养级信息的各组实验中，各保护目标对应的捕食者物种占比以较粗的实线绘制，且覆盖所有权重场景（尽管未实际执行权重分配），用以与以细虚线绘制的纳入营养级信息的实验结果进行对比。营养级权重为最高营养级与最低营养级的比值：比值为3时，对应权重范围为0.3~1；比值为4时，对应权重范围为0.25~1；比值为5时，对应权重范围为0.2~1；比值为6时，对应权重范围为0.15~1；比值为10时，对应权重范围为0.1~1；比值为20时，对应权重范围为0.05~1；比值为100时，对应权重范围为0.01~1。标注“a”表示相同保护目标下不同实验场景间存在极显著差异（p < 0.001）。
