Life history parameters: g, mass-specific growth rate; clutch size; mass of an individual (somatic tissue + eggs of the first clutch) or its somatic tissue (soma = body of a female without eggs); and egg mass. Analyses of the mass-specific growth rates were separated in a region below(glim) and above (gmax) the incipient limiting level (determined by the break-point of the linear regression model with segmented relationships) of the functional response to dietary cholesterol levels. The carbon-related mass of individuals and their somatic tissues was analyzed at maximum growth rates (gmax)
