Price, R. and Warwick, R.M. (1980) Temporal variations in annual production and biomass in estuarine populations of two polychaetes, Nephtys hombergi and Ampharete acutifrons. Journal of the Marine Biological Association of the United Kingdom, 60 (02). p. 481.

Abstract

Production rates and production/biomass ratios have been estimated for a large number of macrobenthic species (Hargrave, 1977; Robertson, 1979). The usefulness of such estimates is limited by a lack of information on their temporal and spatial stability; we are aware of only one study (Sarvala, 1980) in which production has been estimated for more than one year. The present study investigates the stability of the production (P), biomass (B) and P/B values of two polychaete species, Nephtys hombergi Savigny and Ampharete acutifrons (Grube), over a 5-year period.
