Description
Calculates statistics and produces plots of state variables and fluxes. The parameters in the function pars_animal can be modified.
The theory for the standard DEB model can be found in: Kooijman, S. A. L. M. 2010 Dynamic Energy Budgets theory for metabolic organisation. Cambridge University Press.
The standard DEB model accounts for: effects of food availability (X) and temperature (T). These environmental parameters are taken to be constant in pars_animal but other routines let them vary in time.
The animal is decomposed in structure (V) and general reserve (E), and metabolic switching is linked to maturity (H) The animal developes through an embryonic, juvenile and adult phase. Assimilation is switched on at birth Investment in maturity is redirected to reproduction at puberty Organic compounds: X = food, V = structure, E = reserve, P = faeces Mineral compounds: C = carbon dioxide, H = water, O = dioxygen, N = nitrogen waste
Uptake is proportional to surface area, which is taken to be proportional to the structural volume^(2/3): isomorph
