Stress-coping styles are associated with energy budgets and variability in energy management strategies in a capital breeder

Individuals vary in their stress-coping styles, characterized by specific behavioural and physiological traits that influence their response to stressors. Theory suggests that these traits are linked to underlying metabolic mechanisms that affect energy management strategies. Despite the potential of this powerful comparative approach, few studies have explored how stress-coping styles relate to energy management strategies. Using heart rate telemetry data from a large, capital-breeding pinniped, the grey seal (Halichoerus grypus), we sought to investigate the relationship that stress-coping styles may have on energy management strategies.  Background energy expenditures, a proxy for metabolic rate and other background processes, and daily energy expenditures were found to be individually repeatable in grey seal mothers across successive breeding seasons. Proactive individuals, associated with more bold and aggressive phenotypes, exhibited consistently higher background and daily e..., , , # Data from: Stress-coping styles are associated with energy budgets and variability in energy management strategies in a capital breeder

## Description of the data and file structure

Using heart rate telemetry data from a large, capital-breeding pinniped, we sought to investigate the influence that stress-coping styles have on energy management strategies. To do this, we first evaluated the repeatability of energy usage (energy management strategy) in grey seal mothers over multiple consecutive breeding seasons (file: Daily_grey_seal_msDat.txt).  We then investigated the associations that stress-coping styles (resting heart rate variability) may have with energy use and management strategies among grey seals (file: Seasonal_grey_seal_msDat.txt). All code used in the analysis and figures presented in text is included in the RMarkdown html document.
