蜜蜂在数百到数千只的群体中做出觅食和筑巢地点选择的决定。为了有效地做出这些决定,蜜蜂需要在一个空间分布的群体中进行交流。然而,蜜蜂交流的时空动态在集体决策模型中大多被忽视,主要集中在意见动态的平均场模型上。本文运用空间扩展的蜂群集体决策模型,分析了巢或蜂巢的空间属性,以及不同信念状态(未承诺或已承诺)下个体的运动对信息传递速率的影响。蜜蜂摇摆舞的强度是摇摆者浓度的阈值非线性函数。我们的模型范围从将蜂箱视为离散斑块链到连续线(长而窄的蜂箱)。种群阈值招募和种群划分相结合,在具有强种群分散的信息快速传播和种群过度扩散导致的招募失败之间进行了权衡,并创造了有效的群体水平信号检测机制,从而阻止了向低质量目标的招募。
Honey bees make decisions regarding foraging and nest-site selection in groups ranging from hundreds to thousands of individuals. To effectively make these decisions, bees need to communicate within a spatially distributed group. However, the spatiotemporal dynamics of honey bee communication have been mostly overlooked in models of collective decisions, focusing primarily on mean field models of opinion dynamics. We analyze how the spatial properties of the nest or hive, and the movement of individuals with different belief states (uncommitted or committed) therein affect the rate of information transmission using spatially-extended models of collective decision-making within a hive. Honeybees waggle-dance to recruit conspecifics with an intensity that is a threshold nonlinear function of the waggler concentration. Our models range from treating the hive as a chain of discrete patches to a continuous line (long narrow hive). The combination of population-thresholded recruitment and compartmentalized populations generates tradeoffs between rapid information propagation with strong population dispersal and recruitment failures resulting from excessive population diffusion and also creates an effective colony-level signal-detection mechanism whereby recruitment to low quality objectives is blocked.
