Figure 1. Differences in growth rate, Hsp70 level and chill coma recovery time between latitudes across temperatures.

Figure 1

Mean (±1 SE) larval growth rate (A), and Hsp70 level (B) and chill coma recovery time (C) in the adult stage of Ischnura elegans from two northern and two southern populations at three rearing temperatures. Means are slightly offset to aid visualization. Hsp70 levels and chill coma recovery times are quantified after a cold shock treatment (1.5 h exposure to 4°C) given to the freshly emerged adults.
