Figure 1. Thermal persistence of foraging and non-foragingEctatomma ruidum ants. Foragers were marked in the field, and
whole colonies were collected. Thermal persistence time-to-failure
assays were conducted on individual workers, including ants collected
from nests that were not marked as foragers. Statistics are in Table 1.
