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...

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 available to a particular population. We explored the influence of marginal behaviors on the probability of survival of woodland caribou (Rangifer tarandus caribou). We used GPS collars to record the movement and fate of 43 caribou and distributed their habitat use behavior along two axes of a multidimensional scaling. We used Cox proportional‐hazards models to evaluate whether marginality had an effect on mortality risk. 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. Our findings provide an empirical link between behavior and survival, contributing to our understanding of the decline of Rangifer across much of its Canadian distribution. |
