“…During the review process of a manuscript developing a body-size-based model of marine benthic ecosystems (Kelly-Gerreyn et al 2011), re viewers asked why the field data (Kaariainen 2006) and model output did not reflect a bimodal size distribution across the smaller (meiobenthic) and larger (macrobenthic) metazoan invertebrates. These questions were posed based on an acceptance of the classical work of Schwinghamer (1981, 1985, 1988, Schwinghamer et al 1986), who described trimodal benthic biomass spectra with modes corresponding to the conventional body size definitions of micro-, meio-, and macrobenthos.…”
