Comparison of marine mammal population trend classification results from this study with IUCN classifications.

Percentage of marine mammals at the species level in abundance trend categories from this study (n = 27), the equivalent IUCN species (n = 27), and all marine mammal species assessed by IUCN (n = 127). The IUCN does not have a “Non-Significant” category as in this study, but it does have a “Stable” category not used in our results.

按物种层面统计，本研究的27个海洋哺乳动物物种（样本量n=27）、对应27个世界自然保护联盟（International Union for Conservation of Nature，IUCN）评估物种（样本量n=27），以及IUCN评估过的全部127种海洋哺乳动物（样本量n=127），各自在种群丰度趋势类别中的占比情况。世界自然保护联盟未设置本研究中的“无显著变化（Non-Significant）”类别，但设有“稳定（Stable）”类别，该类别未纳入我们的研究结果。
