Dry season = 1.00E-06 animal/m2
Wet season = 1.00E-07 animal/m2
The number is based on the other component's biomasses, general
knowledge of the area and expert estimation (Dalrymple, G., pers. com.)
*For the wet season half
of the number for the dry season was used, assuming that the area in which
this animal feeds and lives is less.*
Biomass per animal = 4500 g (wet weight)
dry weight/wet weight ratio (dw/ww) = 0.35
gramms of carbon/gramms of dry weight = 0.45
Jorgensen, S.E., et al., 1991.
Basal metabolism = 0.014794 Kcal/gww per day
Free living metabolism = basal metabolism x 2
Free living metabolism = Respiration = 0.029587 Kcal/gww*day
Mean food caloric content = 4.5 Kcal/g of dry weight
Mean food Carbon content = 45% of dry weight

P/B Production/Biomass ratio (P/B) = 0.678 yearly rate
Banse, K. and S. Mosher, 1980.
Egestion/Consumption ratio (E/C) = 0.30
Jorgensen, S.E., et al., 1991.
