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.
