Pike Esox lucius in the absence of prey and conspecifics were shown to have the highest habitat-change activity during dusk and to decrease preference for complex habitats in turbid water. As the behaviours indicate routine responses in the absence of behavioural interactions, E. lucius spatio-temporal distributions should be directly affected and thereby more easily assessed and avoided by prey, with potential consequences for encounter rates.
在缺乏猎物和同种个体的情况下，被示意为白斑狗鱼（Esox lucius）在黄昏时具有最高的栖息地改变活动，并减少对混浊水中复杂栖息地的偏好。由于这些行为表明在缺乏行为相互作用的情况下是常规反应，因此白斑狗鱼的时空分布应该会直接受到影响，从而更容易被猎物评估和避免，这可能会对遭遇率产生潜在影响。
