Trade-off between anxious, predator-wary traits and fecundity mediated by their common dependence on the neuroendocrine system. Anxious, predator-wary individuals have low fecundity (red), and calm, less predator-wary individuals have high fecundity (blue). In havens the predominance of fecundity selection may rapidly select for high fecundity, less predator-wary individuals. Hypothesis for the consequences of selection on fecundity in havens. If there is a trade-off between predator-wariness and fecundity (Fig. 1), differences in selection in ‘wild’ populations where predators are present, and ‘havens’ where predators are absent, will lead to the evolution of divergent phenotypes. The size of the circles represents the strength of selection acting on the population, with wild populations balancing predator anxiety and fecundity, whereas in havened populations fecundity is released from the trade-off by the absence of predators, and predator anxiety traits diminish under selection for fecundity. The phenotypes of the resultant populations are coloured to represent their bias/balance between anxious (red), predator-wary traits and fecundity (blue). Selective removal of low anxiety individuals for public facing conservation, and supplementation with anxious, predator-wary wild animals, may help ameliorate selection for fecundity in havens.
