Experiment 1: Refers to the Behavioural Challenge experiment.

‘AggTest’ is the aggression test that was given to half of the individuals, 1 = did receive an aggression test, 2 = no aggression test. ‘Time’ refers to the first or second sample, 1 = is the testosterone concentration sample that was initially taken, 2 = the testosterone concentration sample that was taken after the aggression test. ‘Testos’ is the circulating testosterone concentration in ng/ml. Experiment 2: Refers to the experiment in which we manipulated testosterone concentrations. ‘Treat’ refers to the treatment group, 1 = control, 2 = sham control, 3 = testosterone increase, 4 = testosterone block. ‘Week’ refers to the time points, 1 = week 1 when we conducted pre-treatment aggression tests, 2 = week two when we conducted post-treatment aggression tests. ‘Agg’ refers to the aggression score for each individual. Exp2 treat check: refers to the extra animals that we treated in order to test that the treatments used in experiment 2 worked. Treatment groups are the same as above, and testosterone concentrations were measured pre and post treatment.
