项目摘要

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.

一些同胞动物物种与其资源（例如食物，筑巢地点等）重叠。在这种情况下，不同的规格通常会表现出类似于种内的社会关系。领土，羊群或教育，优势顺序等。该项目着重于某些物种群体的种间社会关系，以及在多大程度上研究了适用于种间的种内社会关系的概念。鸟类，Aegithalos Caudatus率领羊群，其他帕萨林，Parus Major等每天都会加入并离开它们。但是在某些情况下，一对或两对Aegithalos离开了羊群并加入其他混合物种羊群，以薄荷犬的身份移动。食用丽鱼科鱼的虾，有2种“核心学校”和其他3个spp。学校期间通过自己的家园加入了他们。他们的喂养频率高于单独的喂养频率：发现种间社会促进的频率。记录了公认的一种。两种藻类饲养的lig毛，它们是两种物种的年轻贝壳都定居在拉尔夫西亚地区，但siphonaria成年人仅以进入肠形的形状为食，允许ralfsia的生长。此外，在社会上不如住宅类型的siphonaria的迁徙类型扩大了无肠形的区域，从而为藻类的生长提供了更多的空间，从而有更多的空间来解决这两种物种。
