Figure 6From: To sleep or not to sleep: the ecology of sleep in artificial organismsEffects of the number of food patches on average sleep time. Average number of sleep minutes varying the number of food patches (holding the sleep patches number constant): interDistance 0.0: r S = 0.88, N = 105, P < 0.001; interDistance 0.35: r S = 0.87, N = 102, P < 0.001; interDistance 0.7: r S = 0.76, N = 88, P < 0.001.Back to article page
