“…Ventilation rates of 30 to 50 ml min −1 have been reported for adult individuals (~5 g wet wt) of the upogebiids Upogebia pusilla and U. major (Dworschak 1981, Koike & Mukai 1983, whereas rates of 0.6 to 5.5 ml min −1 are typical for similar-sized individuals of the callianassid Nihonotrypaea japonica (Mukai & Koike 1984). The presence of ventilated burrows transforms the otherwise vertical 1-dimensional diffusive transport in sediments into a spatially 3-dimensional vertical and radial bioirrigation transport (Aller 1980, Shull et al 2009). Solute transport within the sediment matrix occurs by molecular diffusion, and solutes enter or leave the sediment both at the sediment−water interface and across burrow walls (Meysman et al 2010).…”

“…The associated bioirrigation or enhancement of solute transport can exceed the transport by molecular diffusion by as much as an order of magnitude. The actual extent of the enhancement depends on factors such as infaunal community composition and sediment type (Aller 2001, Kristensen 2001, Meysman et al 2006b, Shull et al 2009). The mechanism and rate by which infauna ventilate burrows vary considerably within and among taxonomic groups.…”

“…Because of reworking, or ganic matter and microorganisms are displaced (biomixed) within the sediment matrix. Ventilation occurs when animals flush their open-(2 or more openings at the surface) or blind-ended (only 1 opening) burrows with overlying water for respiratory and feeding purposes, and it causes non-local bioirrigation with rapid transport of solutes out of burrows to the overlying water body (Kristensen 2001, Shull et al 2009) ( Table 1). The local solute transport around burrows is also driven by ventilation, and is either of an advective nature via generated pressure or a diffusive nature via increased concentration gradients.…”

“…9B). Under these circumstances solute exchange across the burrow wall must be driven by diffusive bioirrigation (Shull et al 2009). For species with blind-ended burrows in permeable sediments, on the other hand, the ventilation is often sufficiently forceful to allow unidirectional percolation (advective bioirrigation; Fig.…”

The term 'bioturbation' is frequently used to describe how living organisms affect the substratum in which they live. A closer look at the aquatic science literature reveals, however, an inconsistent usage of the term with increasing perplexity in recent years. Faunal disturbance has often been referred to as particle reworking, while water movement (if considered) is re ferred to as bioirrigation in many cases. For consistency, we therefore propose that, for contemporary aquatic scientific disciplines, faunal bioturbation in aquatic environments includes all transport processes carried out by animals that directly or indirectly affect sediment matrices. These processes include both particle reworking and burrow ventilation. With this definition, bioturbation acts as an 'umbrella' term that covers all transport processes and their physical effects on the substratum. Particle reworking occurs through burrow construction and maintenance, as well as ingestion and defecation, and causes biomixing of the substratum. Organic matter and microorganisms are thus displaced vertically and laterally within the sediment matrix. Particle reworking animals can be categorized as biodiffusors, upward conveyors, downward conveyors and regenerators depending on their behaviour, life style and feeding type. Burrow ventilation occurs when animals flush their open-or blind-ended burrows with overlying water for respiratory and feeding purposes, and it causes advective or diffusive bioirrigation ex change of solutes between the sediment pore water and the overlying water body. Many bioturbating species perform reworking and ventilation simultaneously. We also propose that the effects of bioturbation on other organisms and associated processes (e.g. microbial driven biogeochemical transformations) are considered within the conceptual framework of ecosystem engineering.

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.
