反应迟钝有多糟糕？对环境变化的反应延迟对种群生存的影响
How bad is to be slow-reacting ? On the effect of the delay in response to a changing environment on a population's survival
摘要：
我们考虑一个简单的模型人口，其个人的反应有一定的延迟，其栖息地的时间变化。我们研究了在周期性变化的环境和环境突变的情况下，这种延迟回答对种群生存机会的影响，发现对于突变引起的变异程度较低的种群，“慢反应”降低了种群对环境变化的灭绝风险。相反，对于具有高突变幅度的群体，延迟反应降低了存活机会。
英文摘要：
We consider a simple-model population, whose individuals react with a certain delay to temporal variations of their habitat. We investigate the impact of such a delayed-answer on the survival chances of the population, both in a periodically changing environment, and in the case of an abrupt change of it. It is found that for population with low degree of mutation-induced variability, being "slow-reacting" decreases the extinction risk face to environmental changes. On the contrary, for populations with high mutation amplitude, the delayed reaction reduces the survival chances.
