Abstract
A simple mathematical model was constructed on the basis of the results of experiments conducted at constant temperatures. The rate of development predicted was too rapid, but a reduction of 10% in production rate was sufficient to decrease it to near the observed one. Slight time lags in the fluctuation of the respiration rate at changing temperatures were evident. The influence of temperature conditions on net production efficiency (production/assimilation) of larvae seemed highest during the most intensive growth period. The effect of time of day at which the larvae hatch on development duration was studied in the model, and results considered in relation to the regional coexistence of many species in the carrion microhabitat. The outcome of competition in the individual pieces of carrion probably depends on the order of arrival of the different species, and regional species diversity may be increased by the patchy occurrence of the microhabitat in space and time.
