在这里，我们综合了一些最近的经验和理论论文，认为食物网动态的特点是大量的空间和时间的变化，生物体的反应可预测的，通过行为，这些变化的条件。这种对景观的行为反应在空间和时间上驱动了高度适应性的食物网结构。经验证据表明，食物网的基本属性是潜在的尺度不变的，食物网的特点是驼峰形的营养结构与快速和缓慢的路径，重复在不同的分辨率内的食物网。我们把这些经验模式的背景下，最近的食物网理论表明，适应性强的食物网结构赋予稳定的相互作用的生物体在一个可变的世界的组合。最后，我们表明，最近的食物网分析同意这一理论的两个主要预测。我们认为，在食物网理论和应用食物网生态学的下一个主要前沿必须考虑食物网结构的变化的影响。
Here, we synthesize a number of recent empirical and theoretical papers to argue that food-web dynamics are characterized by high amounts of spatial and temporal variability and that organisms respond predictably, via behaviour, to these changing conditions. Such behavioural responses on the landscape drive a highly adaptive food-web structure in space and time. Empirical evidence suggests that underlying attributes of food webs are potentially scale-invariant such that food webs are characterized by hump-shaped trophic structures with fast and slow pathways that repeat at different resolutions within the food web. We place these empirical patterns within the context of recent food-web theory to show that adaptable food-web structure confers stability to an assemblage of interacting organisms in a variable world. Finally, we show that recent food-web analyses agree with two of the major predictions of this theory. We argue that the next major frontier in food-web theory and applied food-web ecology must consider the influence of variability on food-web structure.
