Yellow-bellied marmots: insights from an emergent view of sociality.
Ecological factors explain variation in sociality both within and between species of marmots-large alpine ground squirrels. Fifty years of study, by me and my colleagues, of the yellow-bellied marmots (Marmota flaviventris) at the Rocky Mountain Biological Laboratory, near Crested Butte, CO, USA, has created opportunities to see how sociality changes with population and group size. Over the pas...
متن کاملApplying the coalitionary-traits metric: sociality without cooperation in male yellow-bellied marmots
Mammalian sociality varies both within and between species. We developed a trait-based method to quantify sociality in a continuous way to study the adaptive utility and evolution of male social behavior. The metric is based on 3 key traits—mutual tolerance, collaboration, and partner preference; males with no traits are not social, whereas those with all 3 traits are described as forming coali...
متن کاملA test of the social cohesion hypothesis: interactive female marmots remain at home.
Individuals frequently leave home before reaching reproductive age, but the proximate causes of natal dispersal remain relatively unknown. The social cohesion hypothesis predicts that individuals who engage in more (affiliative) interactions are less likely to disperse. Despite the intuitive nature of this hypothesis, support is both limited and equivocal. We used formal social network analyses...
متن کاملProximate causes of natal dispersal in female yellow-bellied marmots, Marmota flaviventris.
We investigated factors influencing natal dispersal in 231 female yearling yellow-bellied marmots (Marmota flaviventris) using comprehensive analysis of 10 years (1983-1993) of radiotelemetry and 37 years (1963-1999) of capture-mark-recapture data. Only individuals whose dispersal status was verified, primarily by radiotelemetry, were considered. Univariate analyses revealed that six of the 24 ...
متن کاملSocial Variety in the Yellow-bellied Marmot : a Population-behavioural System
Rates of amicable and agonistic behaviour are not correlated either within or between two colonies of Marmota flaviventris nor is there any consistent pattern of rates being higher in one colony than in the other . Rates of social behaviour are related to population density, the age-sex structure of the population, the individual behavioural characteristics of the residents and potential recrui...
