Table 3. Behavioral Data from Day 2.
On Day 2 animals of Ranks 1–4 within each genotype were pooled and compared to No Rank. There was a genotype × group interactions in the duration of social behavior and a main effect of rank in measures of durations of attack, defensive/submissive behavior, non-attack aggression, huddling, and the frequency of attack.
