A natural catastrophic turnover event: individual sociality matters despite community resilience in wild house mice.

摘要: Natural disasters can cause rapid demographic changes that disturb the social structure of a population as individuals may lose connections. These also have indirect effects survivors alter their within-group connections or move between groups. As group membership and network position influence individual fitness, affect how populations recover from catastrophic events. Here we study in after large predation event wild house mice (Mus musculus domesticus), when third adults were lost. Using analysis, examine heterogeneity sociality results varied responses to losing We then investigate these differences overall structure. An individual's reaction associates depended on its prior event. Those less before formed more weak afterwards, while reduced number they associated with. Otherwise, size groups highly robust. This indicates preferences drive adjust behaviour turnover events, despite population's resilience
