ScLi10- Identify study variables in research articles A study tested if acorn ants that are raised in different temperatures are more tolerant to extreme heat or cold. Here is an excerpt of the methods: “After collection from the field, ant colonies were allowed to acclimate to laboratory conditions (~25 °C, an intermediate temperature between our two temperature treatments) for approximately 24 h prior to being randomly assigned to one of two temperature treatments (Percival growth chambers, 36-VL). We used a simple diurnal fluctuation in temperature for both our warm and cool rearing treatments. The warm treatment cycled between 25 (night) and 30 (day) °C; the cool treatment cycled between 20 (night) and 25 (day) °C. These temperature treatments represent a non-stressful range for this species (Diamond et al., 2013), and correspond with typical warm-day conditions in urban and rural habitats, respectively, in our study area; none of these temperature treatments lie outside the range of temperatures experienced by acorn ants at our study sites (Fig. 1). […] Photoperiod in each treatment was 14:10 L:D. Colonies were maintained in the temperature treatments for an average of 65.48 days (± 1SD 8.11). […] We used a dynamic temperature ramping protocol to assess the critical thermal maximum and minimum (CTmax and CTmin), each defined as the loss of muscular coordination, which yields an ecologically relevant tolerance limit (Lutterschmidt & Hutchison, 1997). ” (modified from Harris, B.
