Development of boldness and docility in yellow-bellied marmots

TLDR: The development of personality traits may facilitate animal’s coping with age-dependent requirements and constraints, and suggests an adaptive hypothesis: that these personality traits develop independently and at potentially age-appropriate times.

Table 1. 622 Fixed effects explaining variation in the univariate model of boldness (quantified as the 623 negative of flight initiation distance) for three age-classes in yellow-bellied marmots. 624 Significant effects are in bold. 625

Table 4. 640 641 Repeatability (on diagonal), correlations (below diagonal), and pairwise comparison of 642 repeatability (above diagonal) for docility and boldness for the different age classes 643 (juvenile, yearling, adult) in yellow-bellied marmots. Estimates were obtained from 644 trivariate models for each behaviour considering each age class as a different trait. 645 Estimates of repeatability are slightly different from univariate models (Table 1) because 646 only significant fixed effects were used in these models to avoid overparametrization. 647
