中文简介:
植物授粉网络的拓扑和链接规则近年来备受关注。很难研究的一个方面是网络的时间动态,因为它需要观察网络如何随时间变化。本文利用数学模型对北极植物授粉网络进行了连续两年的研究,并通过简单的统计分布描述了其时间动态(链路的日常装配和拆卸)。除此之外,我们还证明,尽管传粉者群落的组成发生了强劲的变化,并且网络的日常发展与(可用的)天气参数的相关性很差,但这两年的动态却惊人地相似。
课程简介: Topology and linkage rules of plant-pollinator networks have received much attention lately. One aspect that is difficult to study is the temporal dynamics of the network as it requires observation of how the network changes over time. Here we study an Arctic plant-pollinator network in two consecutive years using mathematical models and describe the temporal dynamics (daily assembly and disassembly of links) by simple statistical distributions. Among other things, we demonstrate that the dynamics is strikingly similar in both years despite a strong turnover in the composition of the pollinator community and the day-to-day development of the network poorly correlates with (available) weather parameters.
关 键 词: 植物传粉者; 网络拓扑结构; 数学模型; 时空动态; 统计分布; 气象参数
