Fig. 1. Schematic diagram of the experimental design used to investigate the
relative contribution of developmental plasticity (1), adult acclimation (3)
and combined treatment (2) to adult physiological performance in Glossina
pallidipes. (Broken line represents eclosion.)

Fig. 2. Relative change in mean critical thermal maxima
Tcrit,max for developmental plasticity, adult acclimation
and combined plasticity groups within the acclimation temperature treatments,
expressed as change from the mean of the 25°C group. Asterisks indicate a
significant effect of the acclimation relative to the 25°C group by
one-way ANOVA (P<0.05). Lower and upper error bars represent
minimum and maximum values, respectively.

Fig. 3. Relative change in mean critical thermal minima
Tcrit,min for developmental plasticity, adult acclimation
and combined plasticity groups within the acclimation temperature treatments
expressed as change from the mean of the 25°C group. Asterisks indicate a
significant effect of the acclimation relative to the 25°C group by
one-way ANOVA (P<0.05). Lower and upper error bars represent
minimum and maximum values, respectively.

Fig. 4. Relative change in mean water loss rate for developmental plasticity, adult
acclimation and combined plasticity groups within the acclimation temperature
treatments expressed as change from the mean of the 25°C group. Asterisks
indicate a significant effect of the acclimation relative to the 25°C
group by GLM (covariate: dry body mass; P<0.05). Lower and upper
error bars represent minimum and maximum values, respectively.

Fig. 5. Relative change in mean metabolic rate as indicated by CO2
production for developmental plasticity, adult acclimation and combined
plasticity groups within the acclimation temperature treatments, expressed as
change from the mean of the 25°C group. Asterisks indicate a significant
effect of the acclimation relative to the 25°C group by GLM (covariate:
mean experimental body mass; P<0.05). Lower and upper error bars
represent minimum and maximum values, respectively.
