“…Although some studies have suggested compensation to be important in the feeding biology of an isopod (Moran and Arrontes 1994), no studies on the long-term effects of diverse foods for amphi-pods, small aquatic detritivores, or other marine herbivores that spend a portion of their lives as mesograzers have documented the type of successful compensatory feeding we found for this species (Barlocher and Kendrick 1975, Willoughby and Sutcliffe 1976, Vadas 1977, Kitting 1980, Larson et al 1980, Nicotri 1980, Pomeroy and Levings 1980, Vasallo and Steele 1980, Sutcliffe et al 1981, Robertson and Lucas 1983, Watanabe 1984, Poovachiranon et al 1986, Pennings 1990, Paul and Pennings 1991, Trowbridge 1991, DeLong et al 1993, Graca et al 1993, Pennings et al 1993, Barlocher and Newell 1994, Pockl 1995, Kennish 1996, Olivier et al 1996, Kneib et al 1997).

“…Kristensen (1983) also obtained an increase in bioirrigation activities by N. virens at a warm (20°C) temperature that was probably due to an increased demand in oxygen for metabolic activities. The low biodiffusion coefficient could be related to a reduction of food searching activities (Deschênes 2001), of particle storage in the upper part of the burrow (Olivier et al 1996), and/or to a longer bioirrigation period by the worm (Miron et al 1992). Our results showed that sediment reworking processes by Neanthes virens are affected by temperature.…”

Temperature-induced variations in bioturbation could affect sediment mixing processes in the marine benthic environment. In this study, sediment reworking by Neanthes virens (Sars), a widely distributed polychaete in muddy sand communities of northern temperate latitudes, was studied under different temperature conditions representing winter (1°C), spring and fall (6°C), summer (13°C), and tide pool (18°C) temperatures in the lower St. Lawrence Estuary, Québec, Canada. Sediment reworking was quantified using inert fluorescent particles (luminophores) deposited at the sediment surface. Based on the 1-D luminophore distributions obtained after 5 and 30 d, the use of the specific 'gallery-biodiffusor' model allowed us to quantify both biodiffusion (D b ) and biotransport (V b ) due to the organisms. Our results showed temperature effects on sediment transport. The lowest biotransport and biodiffusion coefficients were measured at 1 and 6°C and did not change with time. The highest biodiffusion occurred at 13°C for both sampling periods. At 18°C, biodiffusion was intermediate while biotransport was maximal. Differences between the 13°C biodiffusive transport and the other temperatures increased with time. Low transport values at 1 and 6°C suggest that a quiescent stage exists for this species at these temperatures, with sediment mixing occurring mostly during burrow construction. On the other hand, sediment mixing resulted from both the burrow construction and maintenance phases at higher temperatures (13 and 18°C).

“…Many nereid worms are known to be omnivorous or to feed on diatoms and macroalgal debris (Fauchald & Jumars 1979, Smith et al 1996 as well as to stimulate the mineralisation of the old fraction of different species of dead plants, including Zostera marina (Kristensen et al 1992, Olivier et al 1996. Orbinidae and Capitellidae are sub-surface deposit feeders (Fauchald & Jumars 1979), which can easily feed on sediment modified by the wrack.…”

Small-scale disturbance and increased nutrients as influences on intertidal macrobenthic assemblages: experimental burial of wrack in different intertidal environments

Wrack (dead, washed-up seaweed and seagrass) buried in soft substrata causes increased organic content and alters the physical structure of sediments. These effects may influence the types and relative abundances of species in the sediment. Such influences can be expected to vary according to the type and organic content of the sediment. In this study, wrack was buried in 3 mudflats and 2 intertidal sandflats (with coarser sediments) in Botany Bay (New South Wales, Australia). The experiments tested the hypotheses that burial of wrack would (1) increase the content of total nitrogen (N) and organic carbon (OC) of sediments; (2) increase the biomass of micro-algae; and (3) alter the abundances of macrofauna in the sediments. Simulated wrack (equivalent amounts of plastic ribbon, without any organic content) was added to other experimental plots to test the above hypotheses when only physical disturbance, not organic enrichment, occurred. Total OC, N and chlorophyll a (chl a) were sampled every 2 wk for 6 wk and macrofauna were sampled after 6 wk. Some taxa (capitellid, orbinid and nereid worms) increased abundances where wrack was added. Nereidae, however, responded only in muddy sediments. The physical structure associated with wrack also caused an increase in numbers of Oligochaeta and increased patchiness in numbers of the soldier-crab Mictyris longicarpus, but only in sites where they were already abundant. Wrack represents a source of food for some taxa. Physical disturbance due to burial of wrack also adds to patchiness and abundance of taxa on sandy and muddy intertidal shores. The major responses of fauna predicted from other studies did not occur.
