Nonlinear models applied to describe the relationship between the intrinsic rate of increase (<i>r</i>_<i>m</i>) for apterous morphs of <i>H</i>. <i>foeniculi</i> and temperature (°C).

Trm = predicted temperature at which the intrinsic rate of increase could reach its maximum, RSS = residual sum of squares, R2 = coefficient of determination, R2adj = adjusted coefficient of determination, and AICc = corrected Akaike information criterion. Nonlinear models applied to describe the relationship between the intrinsic rate of increase (rm) for apterous morphs of H. foeniculi and temperature (°C).
