群居节肢动物在有不同选择时能够做出集体决策。在这项研究中，我们研究了性别群体的组成和庇护所的几何形状如何影响美洲大蠊的聚集模式。我们发现，雄性群体、雌性群体以及由雄性和雌性组成的混合群体具有不同的互动网络，导致对称（两个水平或两个垂直庇护所）和不对称（一个垂直和一个水平庇护所）条件下不同的集体偏好，其根源在于交互吸引力强度和个体趋地性偏好的差异。
Gregarious arthropods are able to perform collective decision-making when having different options. In this study, we investigate how the sexual group composition and the geometry of the shelters influence the aggregation patterns ofPeriplaneta americana. We show that groups of males, groups of females and mixed groups composed of males and females have different interactions’ networks leading to different collective preferences in symmetrical (two horizontal or two vertical shelters) and asymmetrical (one vertical and one horizontal shelter) conditions that take their origin in the differences in the strengths of interattractions and in individual geotaxis preferences.
