密度对蚁群自组织聚集的影响
Role of density in ant self-organized aggregation
摘要
Abstract
Self-organized aggregation is a pervasive and important collective behavior,commonly found in biological species and in human society.It is a multi-disciplinary field widely studied in recent years.To study quantitatively macro-characteristics in self-organized aggregation,we performed experiments with ants (Tetramorium Caespitum) in a homogeneous environment to investigate relationship between self-organized aggregation and ant density.Aggregation intensity of ant groups was measured by hierarchic social entropy and quadrat method.Accurately controlled experiments and statistical analysis showed that ant groups had a close to random spatial distribution at low density,but a prominent state of aggregation emerged at high density.Therefore ant aggregation is density-dependent.Such data will be important regarding the micro-mechanism of ant self-organized aggregation.It is concluded that aggregation emergence is linked closely to density.关键词
