    Notes: Conclusions We have attempted to illustrate the importance of nutrient transfer functions and their key quantitative parameters, power and efficiency. While this brief account has focused on one aspect of nutritional behaviour, the duration of intermeal intervals, the models are equally useful for understanding other components of feeding behaviour such as meal size and food switching. Like-wise, they provide a framework for formulating quantitative predictions about the dynamics of the physiological processes involved in digestion, absorption and the utilisation of food. These aspects are dealt with more fully elsewhere.

    Notes: Abstract We present a formalised, yet flexible, scheme for classifying and symbolising the components of nutrient budgets. The scheme distinguishes hierarchically both among components of the ingesta and among the various sinks to which they are allocated. The primary terms in the budget are distinguished according to either methodological criteria (whether in a given time period they are retained by the animal or dissociated from the body) or functional criteria (whether they contribute to fitness). In both methodological and functional classifications, the primary terms of the budget may be progressively expanded to represent with increasing resolution nutrient allocation. The interplay between the various components of the ingesta and their subsequent allocation may be considered simultaneously using a two-dimensional nutritional matrix.
