Pincheira-Donoso and Hodgson (1) discuss vertebrate endangerment patterns in their response to our recent article (2). They reassessed our conclusion of a bimodal body size distribution of endangerment for all vertebrates but did so using only data on body mass for amphibians. In our study, we collectively analyzed patterns of endangerment across six classes of vertebrates. Contrasting patterns specific to amphibians with results that pertain to all vertebrates fails to compare like to like and as such is perhaps an exercise of unclear value. Pincheira-Donoso and Hodgson (1) suggest that our vertebrate model is inadequate because “increases in endangerment of smaller vertebrates are heavily biased by a single class (Amphibia) . . . ” We investigated this potential bias by refitting our vertebrate model without amphibians …

回复平奇拉-多诺索和霍奇森:最大和最小的脊椎动物灭绝风险都升高[生物科学]

Pincheira-Donoso和Hodgson(1)在对我们最近的文章(2)的回应中讨论了脊椎动物的濒危模式。他们重新评估了我们对所有脊椎动物的双峰濒危体型分布的结论,但只使用了两栖动物的体重数据。在我们的研究中,我们共同分析了六类脊椎动物的濒危模式。两栖动物特有的对比模式与所有脊椎动物的结果都无法按喜好进行比较,因此这可能是一项尚不清楚价值的活动。潘切拉(Pincheira-Donoso)和霍奇森(Hodgson)(1)表明我们的脊椎动物模型是不充分的,因为“较小型脊椎动物的濒危性增加受到单一类别的严重偏见(两栖动物)。。。”我们通过改装没有两栖动物的脊椎动物模型来研究这种潜在的偏见...
