Extension of the intraspecific social organization concepts to the interspecific social relations.

一些共域动物物种在食物、筑巢地点等资源上有重叠。在这种情况下，不同物种往往表现出类似于种内物种的社会关系：属地、集群或学校、优势度等。本项目关注一些物种群体的种间社会关系，以及种内社会关系的概念在多大程度上适用于种间社会关系。在混合物种冬季鸟类群中，尾巴斑雀领导群体，其他斑腿鸟等每天进出它们。但在某些情况下，一对或两只Aegithalo离开群体，加入另一个混合物种的群体，作为花匠移动。在虾类食蟹类中，有2种为“核心群”，另有3种。在学校穿过他们自己的家射击场时加入了他们。在林地栖息的7种蚂蚁中，由于个体大小差异、栖息地大小、拮抗行为和吸纳行为的复合体，同一生活型之间存在等级分层。两种藻类的取食习性是相互竞争的，它们的幼壳都栖息在Ralfsia带上，而Sihonaria成虫仅以蛔虫为食，并允许Ralfsia生长。此外，迁移型的水蚤在社会地位上低于居住型，它扩大了无蛔虫的区域，为藻类的生长提供了更多的空间，从而为两个物种的定居提供了更多的空间。

Some sympatric animal species overlap their resources such as food, nesting site, etc. In such cases, different specis often show social relationsips analogous to the intraspecific ones; territoriality, flocking or schooling, dominance order etc. The project focused on the interspecific social relationships of some species group, and to what extent are the concepts on intraspecific social relationships applicable to the interspecific ones were examined.In mixed-species winter flocks of passarine birds, Aegithalos caudatus leads the flock, and other passarine, Parus major etc, join to and leave from them everyday. But in some cases, a pair or two of Aegithalos leave the flock and join to the other mixed-species flock, moving as floolwers.In mixed-species schools consisting 5 spp. of shrimp eating cichlid fish, 2 species consisted "core school" and the other 3 spp. joined to them during the school passed through their own home range. Their feeding frequencies were higher than those when they were alone: interspecific social facilitation was recognized.Among forest-floor inhabiting 7 ant species, hierarchical stratification among the same life type derived from the complex of body size difference, home range size, antagonistic behaviour and admittive one was recorded.Two species of algal feeding limpets, which are competitive being young shells of both species settle on Ralfsia zone, but Siphonaria adults feed exclusively on Enteromorpha and allow the growth of Ralfsia. Moreover, migratory type of Siphonaria, which are socially inferior to the residential type, Expanded the enteromorpha-free area allowing more space for the growth of algae, thence more space for the settlement of both species.
