Intraspecific Variation in Parental Care May Reflect Variation in Parental Quality.

ABSTRACT: The existence of life-history trade-offs is a fundamental assumption of evolutionary biology and behavioural ecology, yet empirical studies have found mixed evidence for this. Such trade-offs are expected when individuals vary in how they allocate their limited resource budgets between different life-history functions (variation in resource allocation), but they may be masked when individuals vary in how many resources they have acquired that they can later allocate to life-history functions (variation in resource acquisition). We currently lack studies on the extent to which individual differences in behaviour reflect variation between individuals in resource acquisition and resource allocation. Here, we use parental care as a case study for exploring this question. We used the burying be
