The delay between disturbance events and genetic responses within populations is a common but surprisingly overlooked phenomenon in ecology and evolutionary and conservation genetics. If not accounted for when interpreting genetic data, this time lag problem can lead to erroneous conservation assessments. We (i) identify life-history traits related to longevity and reproductive strategies as the main determinants of time lags, (ii) evaluate potential confounding factors affecting genetic parameters during time lags, and (iii) propose approaches that allow controlling for time lags. Considering the current unprecedented rate of loss of genetic diversity and adaptive potential, we expect our novel interpretive and methodological framework for time lags to stimulate further research and discussion on the most appropriate approaches to analyse genetic diversity for conservation.
干扰事件与种群内遗传响应之间的延迟是生态学、进化遗传学和保护遗传学中一种常见但令人惊讶地被忽视的现象。如果在解释遗传数据时不加以考虑，这种时间滞后问题可能导致错误的保护评估。我们（i）确定与寿命和繁殖策略相关的生活史特征是时间滞后的主要决定因素，（ii）评估在时间滞后期间影响遗传参数的潜在混杂因素，以及（iii）提出能够控制时间滞后的方法。鉴于当前遗传多样性和适应潜力前所未有的丧失速度，我们期望我们关于时间滞后的新颖解释性和方法框架能够激发关于分析遗传多样性以进行保护的最合适方法的进一步研究和讨论。
