Increased demographic turnover and isolation precede social fragmentation in Asian elephants.

In 443 wild female Elephas maximus tracked for 12 years, accumulated demographic turnover preceded social network fragmentation into smaller, more isolated communities.

• Why it matters: The study addresses how gradual membership change can push social systems past thresholds, potentially reshaping connectivity and reducing resilience to disturbance.
• What they did: Researchers analyzed social network dynamics over 12 years, tracking community membership and structure while separating effects from member loss versus relationship changes among remaining elephants.
• The result: After demographic turnover, networks fractured into smaller, more isolated communities, with connection changes driven by both disappearing individuals and altered relationships, indicating a persistent state shift.
