“…For example, aggressiveness might be negatively correlated to social sensitivity (see earlier references). In principle, one could use path analysis (see Sih et al, 2002) to quantify correlations among behavioral axes and the relative effects of each of these behavioral axes in determining overall mating success via multiple pathways.…”

“…Individuals expressing those traits at relatively higher levels are then considered to be of higher 'quality', and by implication, higher fitness [3]. In the terminology proposed by Wilson & Nussey [1], this conceptualization of quality can be described as 'the axis of phenotypic variation that best explains variance in individual fitness' Here we provide a hypothetical example based on a study on water striders (Aquarius remigis) by Sih et al [88] using mating success as a measurement of fitness. In this species, males compete for mates and larger size confers increased competitive success and allows males to overcome female resistance.…”

Individual quality has been measured as a variety of different traits and in several different contexts. However, the implications of such measurements in terms of overall fitness are less straightforward than has generally been appreciated. Here we outline some key issues in this regard that have yet to be addressed. Specifically, we consider the importance of both variation in selection on individual and multivariate suites of traits, and of context-specific plasticity in allocation strategies. We argue that an explicit life-history perspective is crucial for understanding variation in quality, as both the strength and direction of selection and an individual's response to it can vary within a breeding season. Hence, 'quality' is not a static characteristic that can be measured by taking longitudinal measures of single traits across a population, but rather a dynamic, multivariate suite of traits that is dependent not only on the selective context, but also on the nature and intensity of selection operating at any given time. We highlight these points by considering recent research on selection and plasticity.

“…Active males will jump on any other adult, males or females; however, some males will attack other males and females more aggressively; these males have been termed 'hyper-aggressive' by Sih & Watters [27]. Males with higher activity have more encounters with females, and thus more mating opportunities than less active males [28]; therefore, hyper-aggressive males are also hyper-harassing males. Consistent with the predictions of our model, Sih & Watters [27] observed that the presence of 'hyper-aggressive' (or hyper-harassing) males decreases overall group mating activity by decreasing female activity.…”

A model of sexual selection and female use of refuge in a coercive mating system

In many non-monogamous systems, males invest less in progeny than do females. This leaves males with higher potential rates of reproduction, and a likelihood of sexual conflict, including, in some systems, coercive matings. If coercive matings are costly, the best female strategy may be to avoid male interaction. We present a model that demonstrates female movement in response to male harassment as a mechanism to lower the costs associated with male coercion, and the effect that female movement has on selection in males for male harassment. We found that, when females can move from a habitat patch to a refuge to which males do not have access, there may be a selection for either high, or low harassment male phenotype, or both, depending on the relationship between the harassment level of male types in the population and a threshold level of male harassment. This threshold harassment level depends on the relative number of males and females in the population, and the relative resource values of the habitat; the threshold increases as the sex ratio favours females, and decreases with the value of the refuge patch or total population. Our model predicts that selection will favour the harassment level that lies closest to this threshold level of harassment, and differing harassment levels will coexist within the population only if they lie on the opposite sides of the threshold harassment. Our model is consistent with empirical results suggesting that an intermediate harassment level provides maximum reproductive fitness to males when females are mobile.
