任何种群的成员受到外来死亡率的影响，其死亡率应随年龄增长而增加。然而，普遍的观点是，成年豆娘和蜻蜓种群并不表现出这种衰老。在这里，我们通过将一系列人口模型拟合到这些早期结论所依据的数据中来挑战这一论点。研究表明，与包括年龄无关死亡率在内的其他模型相比，年龄相关死亡率呈指数增长的模型（Gompertz）通常提供了更简洁的拟合，这表明许多齿鼠确实会衰老。控制系统发育，比较35种odonate物种的日死亡率表明，尽管雄性和雌性死亡率呈正相关，但在那些表现出领地性的物种中，雄性死亡率往往更高。因此，我们首次表明，一旦潜在的系统发育关系得到解释，领地可能会给雄性带来生存成本。
Any population whose members are subject to extrinsic mortality should exhibit an increase in mortality with age. Nevertheless, the prevailing opinion is that populations of adult damselflies and dragonflies do not exhibit such senescence. Here, we challenge this contention by fitting a range of demographic models to the data on which these earlier conclusions were based. We show that a model with an exponential increase in age‐related mortality (Gompertz) generally provides a more parsimonious fit than alternative models including age‐independent mortality, indicating that many odonates do indeed senesce. Controlling for phylogeny, a comparison of the daily mortality of 35 odonate species indicates that although male and female mortalities are positively correlated, mortality tends to be higher in males of those species that exhibit territoriality. Hence, we show for the first time that territoriality may impose a survivorship cost on males, once the underlying phylogenetic relationships are accounted for.
