Dominancia vizsgálata zebrapintyek között
Abstract
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).
