“…Luis and Passos (1995) showed that the composition of the diet is a decisive factor in determining the fatty acid composition of N. diversicolor. Their results confirmed the detritivorous feeding mode as well as the sediment swallowing of N. diversicolor, which was described earlier by Mettam (1979) and Fauchald and Jumars (1979) for different polychaete populations.…”

“…Hediste diversicolor is a very important species in estuarine food webs and shows several feeding techniques: it has been described as a predator, scavenger, deposit‐ and suspension‐feeder (Muus, 1967; Frid & James, 1988; Esselink & Zwarts, 1989; Riisgard, 1991) and is an important prey species for crustaceans, fishes and birds (Heip & Herman, 1979; Davey & George, 1986; Evans, 1988; Zwarts & Wanink, 1993). Hediste diversicolor has a holobenthic cycle without pelagic larvae (Dales, 1950) and its dynamics have been intensively studied along Northern European coasts (Dales, 1951; Chambers & Milne, 1975; Heip & Herman, 1979; Mettam, 1979; Olive & Garwood, 1981; Möller, 1985; Gillet, 1990). Data about dynamics of several H. diversicolor populations in the Iberian Peninsula were available (Sola, 1994; Francés Zubillaga & Saiz Salinas, 1997; A. Dueso & R. Sardá, unpublished data), but only a few studies on secondary production have been carried out (Sprung, 1994; Arias & Drake, 1995).…”

Abstract. Population dynamics and secondary somatic production data of a population of the polychaete Hediste diversicolor (O. F. Müller) are reported. Monthly samples were taken in a small muddy‐sand flat in the Gernika estuary (Basque Country, North Iberian Peninsula) from May 1991 to May 1992. In addition to H. diversicolor abundance, temporal variation of the infauna and sediment conditions were analysed. Size measurements were employed to estimate H. diversicolor biomass and several cohorts were differentiated based on the size distribution. Secondary production was estimated based on cohort summation of growth increments following individual cohorts through time. Results are compared with those of other H. diversicolor populations located along the whole latitudinal gradient of distribution of the species.

“…Hediste diversicolor (OF Müller, 1776) is a polychaete worm widely distributed in estuarine and lagoonal habitats from North Africa to North Europe (Mettam, 1979;Gillet, 1993) at a density of 500-5,000 individuals per square metre (Vedel & Riisgard, 1993). This species shows high physiological tolerance of extreme variations in environmental factors, and can grow and reproduce in different sediment types and also in stressed environments (e.g.…”

Spatial oxygen heterogeneity in a Hediste diversicolor irrigated burrow

International audienceThe heterogeneity of oxygen distribution in a Hediste diversicolor burrow environment was investigated in a laboratory experiment using a 6-mm thick tank equipped with oxygen planar optodes. The twodimensional oxygen distribution in a complete burrow was monitored every 2 min for 4 h. Oxygen concentrations fluctuated over a scale of minutes in the burrow lumen and wall (up to 2 mm) reflecting the balance between worm ventilation activity and oxygen consumption. The magnitude of the three surrounding micro-horizons (oxic, oscillating and anoxic) induced by the intermittent worm ventilation was spatially and temporally variable within the structure. Oxygen variations appeared to be controlled by distance from the sedimentâwater interface and the direction of water circulation. Moreover, there was an apparent âbuffer effectâ, induced by the proximity to the overlyingwater, which reduced the variations of lumen and wall oxygen in the upper part of the structure. These results highlight the heterogeneous distribution and dynamics of oxygen associated with H. diversicolor burrows and ventilation activity. They also highlight the necessity of integrating this complexity into the current burrow-base models in order to estimate the ecological importance of burrowing species in coastal ecosystems
