生物体表型与其环境之间的不匹配可能会导致短期适应成本。在这里,我们表明,一些表型-环境不匹配错误可以通过野生红松鼠中不同类型错误的不对称成本来解释。在没有即将到来的食物脉冲信号时错误地增加繁殖努力的母亲更有可能在食物脉冲确实出现时正确地增加努力。然而,当母亲在即将到来的食物脉冲出现时未能加大努力,就会遭受终生的健身成本,而这些成本只能通过食物补充剂来抵消。因此,在波动的环境中,这种表型与环境的不匹配可能反映出高估环境线索的偏见,并避免犯下代价最高的错误,最终增强终生健康。
Mismatches between an organism’s phenotype and its environment can result in short-term fitness costs. Here, we show that some phenotype–environment mismatch errors can be explained by asymmetrical costs of different types of errors in wild red squirrels. Mothers that mistakenly increased reproductive effort when signals of an upcoming food pulse were absent were more likely to correctly increase effort when a food pulse did occur. However, mothers that failed to increase effort when cues of an upcoming food pulse were present suffered lifetime fitness costs that could only be offset through food supplementation. In fluctuating environments, such phenotype–environment mismatches may therefore reflect a bias to overestimate environmental cues and avoid making the costliest error, ultimately enhancing lifetime fitness.
