Fitness, risk taking, and spatial behavior covary with boldness in experimental vole populations
Individuals of a population may vary along a pace-of-life syndrome from highly fecund, short-lived, bold, dispersive 'fast' types at one end of the spectrum to less fecund, long-lived, shy, plastic 'slow' types at the other end. Risk-taking behaviour might mediate the underlying...

Individuals of a population may vary along a pace-of-life syndrome from highly fecund, short-lived, bold, dispersive 'fast' types at one end of the spectrum to less fecund, long-lived, shy, plastic 'slow' types at the other end. Risk-taking behaviour might mediate the underlying life-history trade-off but empirical evidence supporting this hypothesis is still ambiguous. Using experimentally created populations of common voles (Microtus arvalis) - a species with distinct seasonal life-history trajectories - we aimed to test whether individual differences in boldness behaviour co-vary with risk-taking, space use, and fitness. We quantified risk taking, space use (via automated tracking), survival and reproductive success (via genetic parentage analysis) in 8 to 14 experimental, mixed-sex populations of 113 common voles of known boldness type in large grassland enclosures over a significant part of their adult life span and two reproductive events. Populations were assorted to contain extreme boldness types (bold or shy) of both sexes. Bolder individuals took more risks than shyer ones, which did not affect survival. Bolder males but not females produced more offspring than shy conspecifics.
