Many different approaches are being used in this effort, including cost-benefit models (Roughgarden 1975), phylogenetic analyses (Thompson 1982), models of population dynamics (Addicott 1981; Wolin 1985), and the approach that we adopt in this chapter, the

This form of selection has been studied in many interesting systems, for example reproductive effort (Schaffer 1974; Hastings and Caswell 1979; Bulmer 1985), the timing of seed germination

IntroductionAs amply demonstrated in Sect. II, insects do not live in uniform environments or experience uniform selection. The intensity and direction of selection may change in space and time. The chapters of this section amplify this theme and also consider insect life-cycles in the context of the broader community.
