Aythya fuligula (Tufted duck):  

Implied properties for this entry

Model:  std  

Energy investment, cumulated over the embryo period (left), and allocation during ontogeny

Exploding sectors mean dissipation; numbers denote fractions of mobilized reserve. Endpoints are somatic maintenance S, growth G, maturity maintenance J, maturity or reproduction R. Growth is splitted into overhead and flux fixed in tissue. Reproduction overhead is not idicated, since it is pays at conversion of buffer to eggs/foetuses. The change in reserve equals assimilation p_A minus mobilization p_C. Wet weight W_w and total energy E_W exclude the reproduction buffer in adults. Pies link to budget pages.
