Abstract
"The effect of metabolic rate (MR) on organisms' health maintenance is a long-standing puzzle and empirical data on this issue is contradictory. A theoretical model was developed for understanding animal's energy budget under the food condition of Ad libitum (AL) and food restriction. This model offers a framework for understanding the role of MR and health maintenance mechanism from the perspective of energy tradeoff between food assimilation, growth, metabolism and maintenance. Hornworm (Manduca sexta larva) has been selected as an model to test the energetic tradeoff under different food supply and ambient temperatures. The changes in energy budget can reveal its health maintenance mechanism during growth. The experiments' results show that (1) under food restriction, high temperature can slow down the growth rate to compensate for the high metabolism; (2) the free-feeding larvae slightly decrease the energy allocated to growth as body mass increases, and increase the energy allocated to metabolism, while the food restricted larvae prioritize growth at the expense of metabolism; (3) during growth, the mainly reason of the accumulated damages is caused by the changes in biosynthesis instead of the changes in metabolic energy"--Abstract, page iv.
