The pace-of-life syndrome (POLS) hypothesis predicts associations between
life-history and ‘risky’ behaviours. Individuals with ‘fast’ lifestyles
should develop faster, reproduce earlier, exhibit more risk-prone
behaviour, and die sooner than those with ‘slow’ lifestyles. While support
for POLS has been equivocal to date, studies have relied on
individual-level (phenotypic) patterns in which genetic trade-offs may be
masked by environmental effects on phenotypes. We estimated genetic
correlations between life-history (development, lifespan, size) and risky
behaviours (exploration, aggression) in a pedigreed population of
Mediterranean field crickets (Gryllus bimaculatus). Path analyses showed
that behaviours mediated some genetic relationships between life-history
traits, though not those involved in trade-offs. Thus, while specific
predictions of POLS-theory were not supported, genetic integration of
behaviour and life-history was present. This implies a major role for
risky behaviours in life-history evolution.
