Graphical explanation of the Moran curve parameters. The density independent mortality at a mosquito log density point (log trap catches) is the difference of the log density values between the line of unlimited growth (which intercept is the unlimited growth λ₀) and the log density point; while the density dependent mortality is the difference between the log density values between the line of unlimited growth and the line of density dependent limitation of population growth. When the density dependence is acting (densities > d otherwise density dependence is 0) then the density independent mortality is the difference of log density values between the line of density dependent limitation of population growth and the point. The intensity of density dependent mortality is represented by the slope α.
