Change in social behaviour with age
For this analysis, separation of dolphins of known age and sex in 3 different age groups :
Calf = age 0 to 3 years
Results :
• Higher degree for males compared to females
• Males increased their clustering coefficient when aging
• Closeness: no significant change
Young = age 4 to 10 years
Results :
• Males had lower degree scores and increased less their degree than females
• Males had a higher clustering coefficient compared to females
• Males decreased their clustering coefficient with age compared to females
• Closeness: no significant change
Older = older than 10 years
Results :
No significant change for all metrics.
