Abstract

Traditionally, the rationale for energy flow studies was found in the elucidation of energy transfers within ecosystems or within the practical context of the rational management of resources, but it is now widely recognised that its scope embodies almost all biology, including the field of population dynamics and evolutionary studies. Here, we first describe conceptual models of energy and mass budgets at the level of the individual, the population and the community. However, the emphasis is on the next part in which the practicalities of measuring the various components of these budgets in the marine zoobenthic community are described in detail. The measurement of, among other things, ingestion, absorption, defaecation, excretion, growth, reproduction and respiration is discussed. Finally, attention is paid to the estimation of secondary production of benthic populations and to community-level modelling methods.
