社会性昆虫群体作为生物调节系统：优势网络中的信息流
Social insect colony as a biological regulatory system: Information flow in dominance networks
摘要：
社会性昆虫提供了一个很好的平台，以调查信息流的监管系统，因为他们成功的社会组织基本上是通过有效的信息传递，通过复杂的连接模式之间的殖民地成员。这种行为相互作用的网络表示提供了一个强大的工具，结构以及动态分析的基础监管系统。在本文中，我们专注于优势互动网络中的热带社会黄蜂\textit{Ropalidia marginata} -一个物种的行为观察表明，这种相互作用主要是负责个人之间的信息传输有关他们的殖民地的需要，从而在自己的活动的监管。我们的研究表明，\textit{R. marginata}的优势网络在结构上类似于一类自然进化的信息处理网络，这一事实也证实了一个特定的子结构-“前馈回路”-在许多其他信息传输网络的关键功能组件的优势。通过布尔建模的动态分析证实，网络在小波动下是足够稳定的，但与随机化的网络相比，能够更有效地传递信息。我们的研究结果表明，参与一个共同的结构设计原则，在不同的生物调控系统和可能的相似性方面的影响选择的组织水平，这样的系统。研究结果也是一致的假设，即优势行为已形成的自然选择，以增选的信息传递过程中，这样的社会昆虫物种，除了其主要功能的调解生殖竞争的殖民地。
英文摘要：
Social insects provide an excellent platform to investigate flow of information in regulatory systems since their successful social organization is essentially achieved by effective information transfer through complex connectivity patterns among the colony members. Network representation of such behavioural interactions offers a powerful tool for structural as well as dynamical analysis of the underlying regulatory systems. In this paper, we focus on the dominance interaction networks in the tropical social wasp \textit{Ropalidia marginata} - a species where behavioural observations indicate that such interactions are principally responsible for the transfer of information between individuals about their colony needs, resulting in a regulation of their own activities. Our research reveals that the dominance networks of \textit{R. marginata} are structurally similar to a class of naturally evolved information processing networks, a fact confirmed also by the predominance of a specific substructure - the `feed-forward loop' - a key functional component in many other information transfer networks. The dynamical analysis through Boolean modeling confirms that the networks are sufficiently stable under small fluctuations and yet capable of more efficient information transfer compared to their randomized counterparts. Our results suggest the involvement of a common structural design principle in different biological regulatory systems and a possible similarity with respect to the effect of selection on the organization levels of such systems. The findings are also consistent with the hypothesis that dominance behaviour has been shaped by natural selection to co-opt the information transfer process in such social insect species, in addition to its primal function of mediation of reproductive competition in the colony.
