The effects of adult removal on dispersal of yearling yellow-bellied marmots
BRODY, A. K., and K. B. ARMITAGE. 1985. The effects of adult removal on dispersal of yearling yellow-bellied marmots. Can. J. Zool. 63: 2560-2564. The relative importance of adult-yearling interaction and individual behavioral phenotypes on dispersal of yearling yellow-bellied marmots was investigated. Two marmot colonies near Gothic, Colorado, were studied; one was treated as an experimental c...
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 کاملIndividuality, Social Behavior, and Reproductive Success in Yellow-Bellied Marmots
Current theory suggests that population dynamics are the consequence of the repro? ductive strategies of individuals. Individual differences should be expressed in reproductive output, dispersal, social behavior, and recruitment. Mirror-image stimulation (MIS; i.e., exposure ofthe animal to a large mirror) was used as an independent measure of individuality, which could be distributed continuou...
متن کاملInternational Association for Ecology Sociality and Individual Fitness in Yellow - Bellied Marmots
Theoretical and empirical studies suggest that the age of first reproduction (the age at which reproduction begins) can have a substantial influence on population dynamics and individual fitness. Using complete survival and reproductive histories of 428 female yellowbellied marmots (Marmota flaviventris) from a 40-year study (1962-2001), we investigated causes and fitness consequences of delaye...
متن کاملFitness and hormonal correlates of social and ecological stressors of female yellow-bellied marmots
http://dx.doi.org/10.1016/j.anbehav.2015.11.002 0003-3472/© 2015 The Association for the Study of A The effects of social and ecological stressors on female reproductive success vary among species and, in mammals, previous reviews have identified no clear patterns. However, few studies have simultaneously examined the relation between social rank and stressors and the relationships among rank, ...
