Figure 2. Correlations between behavior and temperature in M.
sanguinipes. A) Proportion of grasshoppers moving towards areas
of greater or lesser insolation compared to their initial location
(n ranges from 5–38 among temperature
categories); B) Proportion of grasshoppers adopting basking orientation
(90°) or facing direction of sun (0°)
(n ranges from 21–37 for among temperature
categories, with the exception of 41–45°C, where
n = 6); C) Proportion of grasshoppers
perched on soil surface that adopted the crouched posture
(n ranges from 5–34); D) mean height of
grasshoppers at initial and final locations (sample sizes same as in E);
E) Air temperature at thorax height (TTX) at the initial and
final location of the grasshopper (numbers below symbols are sample
sizes for each temperature interval); for reference, the pair of
horizontal dashed lines represent the bounds of the TSET
range measured in the laboratory.
