| 英文摘要: | Non-genetic transgenerational acclimation cannot always be relied upon to provide populations with an effective, short-term response to climatic changes. In some species, parents are always right. In the past few years, we have learned that parents can predict the environment the offspring will experience and get them ready for it — a biological head start of sorts. As the climate changes rapidly, some ecologists have suggested that this acclimation may help species along. On the contrary, in this issue of Nature Climate Change Welch and colleagues1 show that under high CO2 conditions a tropical damselfish cannot help their offspring's predation-avoidance behaviour. For them, it will have to be adaptation or bust.
