简介
- An asymmetric increase in night‐time temperatures (NTs) on hot days is one of the main features of global climate change. But the biological effects of an increased night‐time temperature combined with high daytime temperature are unclear.
- We used six thermal regimens to simulate NTs on hot days and investigated the effects of night warming on life‐history traits of the English grain aphid Sitobion avenae. Experimental temperatures fluctuated in continuous diurnal cycles, increasing from 27 °C to a maximum 35 °C and then declining to 27 °C gradually before further dropping to different minima (13, 16, 19, 21, 23 or 25 °C) representing NTs.
- When compared to expectations based on constant temperatures, night warming raised the optimum temperature for development by 3 °C, in contrast to results from experiments where temperature variability was altered symmetrically or in a parallel manner. Night …
