标题： Nested structure acquired through simple evolutionary process

摘要： 嵌套结构，这是一种非随机结构，在植物-动物互利网络中控制合作动态和生物多样性。 这种结构模式已在静态（非增长）网络模型中得到解释。 然而，进化过程也可能影响这种结构模式的形成。 因此，我们提出了一个用于植物-动物相互作用的演化网络模型，并表明通过简单的进化过程，可以定性和定量地预测非随机模式，如嵌套结构和异质连接性。 这一发现意味着可以通过考虑进化过程来简化网络模型，同时也表明存在另一种解释非随机模式出现的原因，并可能从进化角度提供更易理解的见解，以解释植物-动物互利网络的形成。 显示英文摘要

摘要： Nested structure, which is non-random, controls cooperation dynamics and biodiversity in plant-animal mutualistic networks. This structural pattern has been explained in a static (non-growth) network models. However, evolutionary processes might also influence the formation of such a structural pattern. We thereby propose an evolving network model for plant-animal interactions and show that non-random patterns such as nested structure and heterogeneous connectivity are both qualitatively and quantitatively predicted through simple evolutionary processes. This finding implies that network models can be simplified by considering evolutionary processes, and also that another explanation exists for the emergence of non-random patterns and might provide more comprehensible insights into the formation of plant-animal mutualistic networks from the evolutionary perspective.
