1. Introduction
Consistent individual differences in behavior (Koolhaas et al., 1999; Réale et al., 2007; Sih et al., 2004) mediate the interactions between individuals and their environment, notably their response to human-induced rapid environmental change (HIREC, Sih et al., 2011). For instance, as bold individuals are assumed to be fast explorers that are highly aggressive, they might be expected to cope better with environmental change. However, they may also have less flexible behavioral repertoires and often perform better in stable environments (Koolhaas et al., 1999), whereas shyer individuals are more neophobic, but more behaviorally flexible (Koolhaas et al., 1999; Sih et al., 2004). Moreover, the fitness outcomes of the two tactics may be context-dependant (Boon et al., 2007; Dingemanse et al., 2004; Dingemanse and de Goede, 2004; Monestier et al., 2015). Thus, the existence of inter-individual variability in behavior (i.e. different behavioral types) within a population may favor adaption to a wide array of environmental changes (Fogarty et al., 2011; Pearish et al., 2013). Behavioral differences manifested in risky or challenging environments (i.e. stressful situations) are generally interpreted within the “coping style” framework as “a coherent set of behavioral and physiological stress responses which are consistent over time and characteristic to a certain group of individuals” (Koolhaas et al., 1999). Two different phenotypes are well recognized: the proactive and the reactive types (Groothuis et al., 2005; Koolhaas et al., 1999). Proactive individuals are highly aggres sive, take risks and adopt a ‘flight-or-fight’ response in the face of potential danger, whereas reactive individuals tend to react by freezing and, more generally, being passive (Koolhaas et al., 2010, 1999). Physiologically, proactive individuals predominantly display a high sympathetic reactivity and a low parasympathetic and hypothalamus-pituitary-adrenal (HPA) reactivity, whereas reactive individuals predominantly show a high HPA and parasympathetic reactivity, but a low sympathetic reactivity (Ellis et al., 2006; Koolhaas et al., 1999). However, a link between the neurophysiological and behavioral dimensions of the stress response has been described only in a few species (in mice and rats: Koolhaas et al., 1999; birds: Carere et al., 2003; fish: Overli et al., 2005). Inter-individual differences in behavior, and particularly in the stress response, may affect life-history traits and, ultimately, fitness (Smith and Blumstein, 2008). Some theoretical (Wolf et al., 2007) and empirical (Biro and Stamps, 2008; Careau et al., 2008; Stamps, 2007) studies have indicated a correlation between behavior and individual performance, generally indexed as growth rate or fecundity. Stamps (2007) and Biro and Stamps (2008) predicted a positive relationship between boldness, activity or aggressiveness and an individual’s growth rate, body size and metabolic rate (Careau et al., 2008; Lantova et al., 2011). Although this information would contribute to a better understanding of behavioral tactics and life history evolution (Bell et al., 2007; Del Giudice et al., 2011; Smith and Blumstein, 2008), studies on the link between coping style, their neuro-physiological basis and individual performance are rare due to the difficulty of obtaining such detailed individual data in wild populations (Dingemanse et al., 2002; Herborn et al., 2010).
