FIGURE 2. Relationships for behavioural metrics in the offspring. (a ) Offspring and parental activity; (b ) activity across experimental groups; (c ) number of contacts with novel object and number of contacts by parent. Light green and orange represent offspring which matched environment relative to their parents (green enriched, orange poor). Dark green (enriched) and orange (poor) represent individuals which mismatched environment relative to their parents. Solid lines in (c ) offspring environments.
