“…It is also remarkable that MN-sediment containing a mixture of Nereis diversicolor and M. viridis had a partitioning of reaction pathways similar to the N-sediment (Table 2). Higher ventilation activities by N. diversicolor than M. viridis (Quintana et al 2011) were apparently responsible for more oxidized conditions in the MN-sediment, which may have hampered sulfate reduction as also noted by Banta et al (1999). The higher redox in N. diversicolor than M. viridis sediment (Fig.…”

“…Marenzelleria viridis is a surface deposit-feeder that ventilates its 30 to 40 cm deep vertical I-or J-shaped burrows in sandy sediment by ciliary (George 1966, Essink & Kleef 1988 and possibly muscular (Quintana et al 2011) action. Strong evidence indicates that M. viridis has the capacity to outcompete the native Nereis diversicolor in certain shallow areas (Essink & Kleef 1993, Kotta et al 2006.…”

“…Nevertheless, its ventilation activity is not very intense as indicated from the lack of an oxidized halo around burrows. Thus, adult individuals are reported to ventilate their blind-ended burrows at an average rate of < 4 ml h -1 (Quintana et al 2011). Much of the return water apparently percolates slowly through the sediment back to the surface and increases the exchange of solutes across the sedimentwater interface (Quintana et al 2007).…”

The contrasting effects of the invasive Marenzelleria viridis and the native Nereis diversicolor on benthic metabolism, partitioning of reaction pathways and distribution of inorganic porewater (C and N) solutes in homogenized sandy sediment were investigated experimentally over a period of 1 mo. The 2 species were studied separately and in combination to observe possible effects and interactions. Benthic O 2 uptake and total CO 2 (TCO 2 ) release were affected similarly by M. viridis, N. diversicolor and the two in combination, with roughly a doubling after 1 to 2 wk compared to defaunated sediment. Sulfate reduction after 1 mo, on the other hand, was more than twice as high in sediment inhabited by M. viridis alone than in any other treatment, even when combined with N. diversicolor. Denitrification estimated from benthic TCO 2 release, porewater reaction stoichiometry and nutrient fluxes was largely unaffected by the presence of fauna. Accordingly, the partitioning of reaction pathways after 1 mo revealed that M. viridis stimulated sulfate reduction at the expense of aerobic respiration. Most of the oxygen uptake in M. viridis sediment was apparently due to enhanced oxidation resulting from an upward drifting front of sulfide as indicated by low redox and the appearance of Beggiatoa sp. near the surface. Porewater solute profiles showed that M. viridis was capable of stronger and deeper irrigation than N. diversicolor despite ~10 times higher burrow ventilation by the latter species. This effect was caused by percolation of return water in the deep (> 20 cm) I-or J-shaped burrows of M. viridis compared to the flushing of the more shallow (6 to 8 cm) U-shaped burrows of N. diversicolor. A replacement of the native N. diversicolor with the invasive M. viridis as the dominant burrow-dwelling polychaete in shallow coastal sediments will probably affect the biogeochemical functioning and ecological stability of the ecosystem. Among other things, organisms tolerant to sulfide are likely to be favored at the expense of more sensitive species.

“…Since flux measurements were conducted several times in each boxcosm, linear mixed effects modelling was chosen as the most suitable statistical method for the statistical analysis of the non-independent data (Quinn & Keough 2002). To assess the effects of bioturbation on nutrient fluxes, linear mixed (between/ within subject) effects modelling was used with independent categorical, fixed be tween subjects variable 'Species' (3 levels: unbioturbated control, M. affinis, Marenzelleria) and within subjects variable 'Day' (3 levels: Days 33, 60, 74).…”

Effects of bottom water oxygenation and macrofaunal colonisation on benthic fluxes of nitrogen (N), phosphorus (P) and silicon (Si) from long-term anoxic Baltic Sea bottom sediment were investigated. Sediment boxcosms from an anoxic site at 150 m depth in the open Baltic proper were incubated in the laboratory to follow the development of benthic nutrient fluxes during 74 d exposure to flow-through of oxygen-rich water. In contrast to traditional end-point experimental designs, our repeated measurement approach allowed for separation of transient and long-term effects of oxygenation and bioturbation on benthic nutrient recycling. The composition, but not the rate, of the benthic total dissolved N efflux changed by oxygenation from being dominated by NH 4 in situ to being mostly composed of NO 2 + NO 3 and dissolved organic N (DON) under oxic conditions. Oxygenation in the boxcosms decreased the benthic efflux of dissolved silicate (DSi) and essentially shut off the in situ flux of dissolved inorganic phosphorus (DIP). After 20 d of oxygenation, 2 bottom macrofauna taxa, the polychaete Marenzelleria spp. and the amphipod Monoporiea affinis, were introduced to a subset of the boxcosms. Bioturbation by either taxa increased the efflux of dissolved inorganic N (DIN), DON and DSi to the overlying water. The Prich benthic flux under in situ anoxic conditions roughly approached Redfield N:P stoichiometry after oxygenation in the sediment boxcosms. Upon addition of macrofauna, bioturbation generated even higher N:P flux ratios.

“…occur in high densities, they can, through their deep burrowing activity, have a significant impact on these biogeochemical cycles. Quintana et al (2011) found that Marenzelleria viridis had two types of ventilation -a muscular pumping of water out of the burrow and a ciliar pumping of water into the burrow. Significant amounts of water percolate upwards to the sediment surface, which will also have a significant effect on the reduction of sulfate in the sediment .…”

Consequences of artificial deepwater ventilation in the Bornholm Basin for oxygen conditions, cod reproduction and benthic biomass – a model study

et al. 2015

Abstract. We develop and use a circulation model to estimate hydrographical and ecological changes in the isolated basin water of the Bornholm Basin. By pumping welloxygenated so-called winter water to the greatest depth, where it is forced to mix with the resident water, the rate of deepwater density reduction increases as well as the frequency of intrusions of new oxygen-rich deepwater. We show that pumping 1000 m 3 s −1 should increase the rates of water exchange and oxygen supply by 2.5 and 3 times, respectively. The CRV (cod reproduction volume), the volume of water in the isolated basin meeting the requirements for successful cod reproduction (S > 11, O 2 > 2 mL L −1 ), should every year be greater than 54 km 3 , which is an immense improvement, since it has been much less in certain years. Anoxic bottoms should no longer occur in the basin, and hypoxic events will become rare. This should permit extensive colonization of fauna on the earlier periodically anoxic bottoms. Increased biomass of benthic fauna should also mean increased food supply to economically valuable demersal fish like cod and flatfish. In addition, re-oxygenation of the sediments should lead to increased phosphorus retention by the sediments.
