Comparative studies of mortality in the wild are necessary to understand the evolution of aging; yet, ectothermic tetrapods are underrepresented in this comparative landscape, despite their suitability for testing evolutionary hypotheses. We present a study of aging rates and longevity across wild tetrapod ectotherms, using data from 107 populations (77 species) of nonavian reptiles and amphibians. We test hypotheses of how thermoregulatory mode, environmental temperature, protective phenotypes, and pace of life history contribute to demographic aging. Controlling for phylogeny and body size, ectotherms display a higher diversity of aging rates compared with endotherms and include phylogenetically widespread evidence of negligible aging. Protective phenotypes and life-history strategies further explain macroevolutionary patterns of aging. Analyzing ectothermic tetrapods in a comparative context enhances our understanding of the evolution of aging.

变温四足动物的不同衰老速率为衰老和长寿的进化提供了见解

为了了解衰老的演变,有必要对野外死亡率进行比较研究;然而,变温四足动物在这种比较景观中的代表性不足,尽管它们适合测试进化假设。我们利用 107 个非鸟类爬行动物和两栖动物种群(77 个物种)的数据,对野生四足变温动物的衰老率和寿命进行了研究。我们测试了关于体温调节模式、环境温度、保护表型和生活史节奏如何影响人口老龄化的假设。在控制系统发育和体型的情况下,与恒温动物相比,变温动物表现出更高的衰老率多样性,并且包括系统发育上广泛存在的可忽略不计的衰老证据。保护性表型和生活史策略进一步解释了衰老的宏观进化模式。在比较背景下分析变温四足动物可以增强我们对衰老进化的理解。
