Table 3.

Behavioral strategies for thermal migration in response to four combinations of direction of locomotion and rate of temperature change

Direction relative to preferred temperature ΔT/dt Experiment Behavioral strategy
Away Downstep wild type Turn
Downstep thermophilic
Away + Upstep wild type Turn-and-run
Upstep cryophilic
Toward Downstep cryophilic No response
Toward + Upstep thermophilic Run
  • Plus signs indicate ΔT/dt > 0; minus signs indicate ΔT/dt < 0. Behavioral strategies are defined in the legend of Table 1.
