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).
