“…Variability of the feeding methods between the deposit and filter feedings is also known in other estuarine macrobenthos such as spionid polychaetes (Taghon et al 1980, Taghon & Greene 1992, bivalves (Hughes 1969, Olafsson 1986, and a gastropod (Kamimura & Tsuchiya 2004).…”

Abstract:The three Hediste species H. japonica, H. diadroma and H. atoka (Polychaeta: Nereididae) live in burrows in estuarine intertidal flats in eastern Asia and have been regarded as surface deposit feeders. Their filter-feeding behavior was investigated in laboratory experiments where the worms were placed in a U-shaped glass tube. The behavior is basically the same among the three species and the same as that previously observed in H. diversicolor inhabiting Atlantic coasts and consists of the following four steps: (1) Moving up to the end of the tube; (2) retreating slowly down, with the anterior body expanded laterally and moving from side to side in semicircles, making a transparent, funnel-shaped mucous net; (3) orientation of the head at 2.5-6.0 cm below the end of the glass tube, and pumping water through the net by means of active undulating movements of the body for 1-5 min; (4) moving forward and swallowing the mucous net together with the trapped particles. This behavior is accelerated by adding organic particles to the seawater. Such facultative filter feeding is judged as a unique generic characteristic of Hediste among the Nereididae and its ecological significance is discussed in relation to their estuarine habitats.

“…The fauna is well adapted to the strongly variable tidal currents that res.uspend the surficial organic matter regularly (Boon & Duineveld 1996). The predominant interface feeders are adapted to more variable food sources than subsurface-deposit feeders by changing their feeding strategy according to current flow conditions (Taghon 1980). During the period 1975 to 1984, when eutrophication drastically increased in muddy habitats of the inner German Bight, opportunistic short-lived species with an adaptive feeding behavior became dominant; longlived species and many subsurface dwellers (such as Amphiura filiformis, Echin0cardiu.m cordaturn and Nucula nitidosa) decreased (Rachor 1990).…”

We investigated the macrobenth~c faunal composition, vertical distnbution, biomass, abundance and trophic structure in 4 North Sea sediments with contrasting quantity and quality of organic matter and with different hydrodynamic environments. The vertical distribution of macrofauna biomass generally followed the TOC (total organic carbon) profiles. The trophic structure reflected differences in relative quality of the organic matter In the high amount-high quality TOC sediment at the German Bight station, most organisms were found at shallow sediment depths (<2 cm), mainly feeding on freshly deposited or (re-)suspended material as interface or suspension feeders. Skagerrak sediments, containing a large amount of refractory organic matter, supported a small-sized deeply penetrating fauna (up to 20 cm) consisting mainly of deep-living deposit feeders and also endobenthic predators. Highest diversity of trophic groups, largest individual sizes and deepest distribut~on were found in sediment with organic matter of intermediate quantity and quality at the Frisian Front. The highly dynamic, coarse-grained Broad Fourteens sediments were very poorly inhabited, probably due to the extremely high hydrodynamic stress and low quantity of TOC. With the aid of a simple dlagenetic model, we analysed the potential effect of bioturbation on the distribution of food in the investigated sediments. The model predicted for a given bioturbation coefficient that total mineralization rate at depth reaches an optimum when the arriving material is of intermediate quality, whereas it is not possible for macrofauna to redistribute the organic matter up to depth when the quality of the arriving mater~al is high. The results of the diagenetic model agreed well with our characterization of the fauna community on the basis of pnncipal bioturbation categories (species causing surface deposition, biodiffusion, conveyor belt transport). Strong mixing by biodiffusion was observed at the station which had organic matter of intermediate quality (Frisian Front) and minimal mixing at the German Bight station, w h c h was charactenzed by the high quality of the arriv~ng organic matter

“…Trophic-functional groupings were also used, adapted from Fauchald and Jumars (1979) and Dauvin and Ibanez (1986): S, suspension feeders; SD, surface-deposit feeders; SSD, subsurface-deposit feeders; C, carnivores/herbivores. Moreover, some animals living within the benthic boundary layer may feed by using a mixed strategy (Group M), behaving as deposit or suspension feeders in response to varying boundary flow rates (Taghon et al, 1980;Levinton, 1991;Taghon and Greene, 1992).…”

We analyse the effects of coastal defence structures, mainly low crested (LCS), on the surrounding intertidal and subtidal infaunal assemblages and mobile fauna. The results summarise joint studies within the DELOS project in Spain (Mediterranean Sea), Italy (Adriatic Sea) and UK (English Channel and Atlantic Ocean). We demonstrate that univariate analysis did not generally identify LCS impacts, but multivariate analyses did, this being a general trend across all locations and countries. Changes in sediment and infauna seem to be inevitable and usually tend to induce negative changes, particularly on the landward side and in the presence of additional structures or after beach nourishment. The consequences of LCS construction always depend on the response of the assemblages inhabiting a given region. However, to assess the ecological importance of the induced changes and to provide additional monitoring criteria, likely indicator species should be taken into account. The presence of species either coming from the new hard bottoms or associated to physical disturbances is viewed as a negative impact, while the potential nursery role of LCS is a positive one. The combined use of monitoring and forecast models allows to identify these impacts and may play a relevant role in mitigation protocols. Finally, our work supports the feasibility of introducing design criteria tending to facilitate a positive evolution of the assemblages surrounding the structures once the changes due to the presence of the LCS are completed and the new situation tends to become more stable
