Abstract Abstract. Theoretical and experimental studies of assessment in animal contests have, until now, focused on disputes between single individuals. However, whereas single competitors usually avoid fights with opponents that are larger or stronger than themselves, in contests between social groups competitors might be expected to adjust their agonistic behaviour according to the number of individuals in their own and the opposing group. This hypothesis was tested using playback… 

Free-ranging dogs assess the quantity of opponents in intergroup conflicts

The results provide the first indications that a representation of quantity based on noisy mental magnitudes may be involved in the assessment of opponents in intergroup conflicts and leave open the possibility that an additional, more precise mechanism may operate with small numbers.

Roaring and social communication in African lions: the limitations imposed by listeners

In some social mammals, loud calling not only serves to advertise ownership of a territory and attract mates but also plays a vital role in allowing social companions to maintain contact when they

Maternal grouping as a defense against infanticide by males: evidence from field playback experiments on African lions

Female lions roar in order to stay in contact with their pridemates and to defend their territory against other prides. In doing so, however, they risk attracting die attention of potentially

Location and group size influence decisions in simulated intergroup encounters in banded mongooses

The findings exemplify the importance of the combined effect of location and group size on group decisions during impending intergroup contest.

Communal singing in the cooperatively breeding subdesert mesite Monias benschi: evidence of numerical assessment?

This study investigated the idea that the social structure of groups may be important in determining the outcome of contests between groups in the subdesert mesite, a group-living bird that produces communal songs during aggressive territorial interactions with other groups.

Against all odds: Numerical assessment by tufted capuchin monkeys

The absence of an effect of the numerical asymmetry on willingness to approach the playback speaker suggests that subordinate groups benefit from engaging in intergroup aggression with larger neighbors, despite the high probability of losing.

Development of cooperative territoriality in juvenile lions

Experimental evidence is presented that juvenile lionesses make a gradual transition to group-territorial defence between weaning and sexual maturity, and the ability of juveniles to assess relative numbers as an adaptation for assessing the risk of territorial conflict is interpreted.

Interaction location outweighs the competitive advantage of numerical superiority in Cebus capucinus intergroup contests

It is demonstrated that contest outcome depends on an interaction between group size and location, such that small groups can defeat much larger groups near the center of their home range.

Subordinate male black howler monkey (Alouatta pigra) responses to loud calls: Experimental evidence for the effects of intra-group male relationships and age

When assessing a group's overall fighting ability, functional group size (i. e. the number of cooperative members willing to confront opponents) may be more important than actual group size. Despite
