Several fish species are characterized by social systems in which
individuals prefer to interact with specific group mates. However, there
is no clear evidence that such associations are equitable, i.e. they are
mutual between individuals. We addressed this issue in the guppy (Poecilia
reticulata), a species in which social network analyses have evidenced
non-random social associations between individuals. We measured the mutual
preference in pairs of guppies that previously familiarized in groups of
either two or six individuals. To estimate the equitability of social
associations, we first tested the preference of one fish for a familiar
stimulus fish over an unfamiliar stimulus fish, and then, we similarly
tested the preference of the other fish. Irrespective of the group size
experienced during familiarization (two or six individuals), we found a
within-pair consistency in the preference for the familiar fish,
indicating that guppies developed social associations that are mutual
between individuals. In a further condition, we tested pairs of unfamiliar
individuals to assess the role of familiarity in equitable social
associations. We found that equitable social associations did not develop
in absence of previous familiarization and were not based on spontaneous
preferences or phenotypic assortment. Our results demonstrate that
familiarity mediates the development of equitable social associations in
guppies and suggest that this behavior may be more widespread than
previously considered.
Cattelan et al 2018_equitability_guppiesThe dataset contains the social
preference of each subject for a familiar stimulus fish over an unfamiliar
stimulus fish. Previously the fish were subjected to three familiarization
conditions. The column "treat" includes the two-individual
familiarization condition ("pair"), the six-individual
familiarization condition ("group") and the unfamiliar condition
("unf").
