An intertidal mudflat in the Lynher estuary, Cornwall, U.K. has been the site of intensive investigations of energy flow through its biological compartments, and of interactions between its compartments. Joint (1978) quantified autotrophic and heterotrophic microbial production both in the water column and sediments. Several detailed studies have been made of energy flow within the macrobenthos and meiobenthos (Price & Warwick, 1980a,b; Tear & Price, 1979; Warwick, 1981; Warwick & Price, 1975, 1979). Field manipulations (caging experiments) have been conducted to investigate trophic relationships between the faunal and floral components (Warwick et al., 1982; Gee et al., 1985). The results of these and other unpublished studies have been assembled into a steady state energy flow diagram and a dynamic simulation model of the benthic system by Warwick et al (1979) in which most of the flows between compartments have been actually measured rather than assumed, and these models have now found their way into a number of authoritative texts (e.g. Longhurst, 1981; Mann, 1982).
