Effect of behavioral marginality on survival of an alpine ungulate
Abstract Inter‐individual variability in behavior has been studied extensively for a wide range of species. However, few researchers have considered marginality, defined as the degree to which a choice made by an individual is located at the margins of the distribution of all possible choices availa...

We found that individuals that exhibited marginal behavior had higher mortality risk than more conformist individuals. Caribou is a social species; thus, sharing a common habitat use strategy is likely an adaptation for minimizing the risk of predation.
