Total number of indications by scent-matching meerkats (Suricata suricatta; n = 5) made on targets (T), environmental controls (EC) and blank controls (BC) for brown house snake (Boaedon capensis; clear bars) and puff adder (Bitis arietans; black bars) treatments. For brown house snake, indications on targets differed significantly from random choice and from indications on environmental controls. Indications on environmental controls were not significantly different from random choice. No blanks were indicated. For puff adder, indications on targets and environmental controls were not significantly different from each other, but were from indications made on blank controls (indicated by *). All indications differed significantly from random choice. Error bars represent standard error. Arrows in insert indicate the position of the holes made in the tubes and lids to allow for sufficient airflow for scenting purposes, and ‘A’ demonstrates the position of the scent cloth within each tube.
