Parental effect on offspring behaviour
For the offspring, the best-fit model after correcting for overdispersion indicated that offspring activity was only significantly influenced by parental activity, increasing with increased parental activity (estimate= 5.28, z-value: 2.61, df=1, p=0.009) (Fig. 2a-b; Table S4a). No other equivalent model was found (Table S4a).
The number of contacts with the novel object was significantly affected by the offspring environment (estimate= 0.48, z-value: 2.44, df=1, p= 0.008), parental environment (estimate= -0.31, z-value: -2.54, df=1, p= 0.01) and increased with the increased number of contacts by the parents (estimate=1.30, z-value: 7.16.57, df=1, p= 0.03) (Fig. 2c). No other equivalent model was found (Table S4b).
