Title:Dominancia vizsgálata zebrapintyek között
Social hierarchy is one of the most often used terms, to describe the relationships among animals living in groups. However, the bigger the groups are, the bigger the chance is that the observed structure will not be linear, but network-like. The investigation of dominance hierarchies are interesting, because they are often related to other social behaviour, and regulate the access to different resources. Previous studies on cooperation between female zebra finches (Taeniopygia guttata) have shown, that birds help each other in an asymmetric manner (Rigler, 2011).
