P>1。作用于觅食活动的选择性压力限制了相互作用的强度，从而限制了食物网的稳定性和能量可用性。2．由于这种选择性压力通常是在个体层面上测量的，并且大多数实验和理论工作都集中在简单的环境上，因此将适应性觅食与群落规模模式联系起来仍然是一个很大的挑战。3．最近的一些模型纳入了不同社区的觅食适应。这些模型通过进化或行为变化纳入适应的方式有所不同，并以各种方式定义个体适应性。4。尽管存在这些差异，但还是出现了一些将适应与群落结构和功能联系起来的一般性结果。在本文中，我介绍了这些不同的模型并强调了它们的共同结果。5．自适应觅食为大型食物网模型提供了稳定性，并成功预测了食物网内的相互作用模式以及其他拓扑特征，例如食物链长度。6。适应性觅食和其他结构因素之间的关系特别取决于当地社区与周围社区的联系程度（元社区方面）。
P>1. Selective pressures acting on foraging activities constrain the strength of interaction, hence the stability and energetic availability in food webs.2. Because such selective pressures are usually measured at the individual level and because most experimental and theoretical works focus on simple settings, linking adaptive foraging with community scale patterns is still a far stretch.3. Some recent models incorporate foraging adaptation in diverse communities. The models vary in the way they incorporate adaptation, via evolutionary or behavioural changes, and define individual fitness in various ways.4. In spite of these differences, some general results linking adaptation to community structure and functioning emerge. In the present article, I introduce these different models and highlight their common results.5. Adaptive foraging provides stability to large food web models and predicts successfully interaction patterns within food webs as well as other topological features such as food chain length.6. The relationships between adaptive foraging and other structuring factors particularly depend on how well connected the local community is with surrounding communities (metacommunity aspect).
