Repeatability and reproductive consequences of boldness in female gray seals

Repeatability and reproductive consequences of boldness in female gray seals Wild animals show consistent individual variation in behavior across time and/or contexts, now referred to as animal personality.

Abstract

Wild animals show consistent individual variation in behavior across time and/or contexts, now referred to as animal personality. While this variability may have important ecological and evolutionary implications, how and why variation in animal personality is maintained in a natural population remains unclear. In this study, we assessed the influence of environmental and biological sources of variation on behavioral responses measured along the shy-bold continuum in a long-lived, iteroparous marine mammal, the gray seal (Halichoerus grypus). Between 2008 and 2016, 469 females from the Sable Island, Nova Scotia breeding colony of gray seals were given a boldness score in response to a human approach, designed to stimulate maternal defense of offspring. Using generalized linear mixed-effects models (GLMM) in a Bayesian framework, we show that boldness is highly repeatable between and within years. There were age differences in boldness, with younger females being less bold than older, more experienced females providing some support for the life history trade-off hypothesis. We further used GLMMs to assess sources of variation on offspring weaning mass. We found that young females that were bolder produced heavier pups than shyer counterparts, and that pups produced by bolder females were on average ~ 2 kg heavier
