Fig. 7. Changes in a signaller's behaviour after agonistic level 2 (threat display)
accompanied by urine release (open columns, N=42 bouts) or not
accompanied by urine release (filled columns, N=108 bouts). Responses
are measured as changes in the relative frequency of certain agonistic levels
(level -2, -1, 0, 1, agonistic level lower than the initial level; level 2,
agonistic level equal to the initial level; levels 3-5, agonistic level higher
than the initial level) from the current to the following time interval.
Asterisks denote significant differences between the behaviours following
agonistic level 2 with urine release and agonistic level 2 without urine
release (*P<0.05, **P<0.01;
multivariate ANOVA). Values are means +1 S.E.M.
