“…Direct methods can be appropriate for certain surface or sub-surface deposit feeders (Rowden et al 1998, Hollertz & Duchêne 2001, Lohrer et al 2005, whereas particle-tracer methods are appropriate for organisms inducing strong vertical displacement of sediment particles (e.g. gallery biodiffusors, conveyor belt deposit feeders) , Caradec et al 2004, Ouellette et al 2004, Maire et al 2006.…”

This review lists and discusses the different methods currently available to assess sediment reworking by benthic infauna. Direct methods are used to estimate the amount of sediment transported by infauna at the sediment-water interface during a given period of time. Particle-tracer methods are used to quantify the vertical distribution of particle tracers within the sediment column. Tracers are classified based on their mode of introduction at the sediment -water interface (i.e. whether they occur naturally or are deliberately introduced at the onset of the experiment). The main characteristics of each method, including modelling aspects, are presented, and their respective advantages and drawbacks are outlined with a particular emphasis on their accuracy, spatial (i.e. both horizontal and vertical) and temporal resolutions. Direct and particle-tracer methods assess different components of sediment reworking. Selection of the most appropriate approach depends on the specific question(s) to be answered, as well as other factors, including the behaviour of the organisms studied, the spatial and temporal scales considered, and whether the experiments are carried out in situ or under controlled laboratory conditions.

This experimental study examined the interactive effects of bioturbation and settling organic matter (OM) on the fate (burial and remobilisation) of 2 surface-deposited contaminants in Baltic Sea sediment: the metal Cd and a hydrophobic organic pollutant, the flame retardant BDE-99. Three macrofaunal species with diverse feeding and bioturbation strategies were used: the amphipod Monoporeia affinis, the clam Macoma balthica and the polychaete Marenzelleria spp. Radiolabelled contaminants were added to the sediment surface in association with 3 different OM types: (1) phytoplankton, (2) terrestrial lignin and (3) Baltic sediment. Bioturbation by all species increased the retention of both contaminants in the sediment, most effectively M. affinis and M. balthica. A decoupled transport of Cd and BDE-99 by Marenzelleria was observed. Generally, Marenzelleria buried the highest amount of Cd into the sediment but also caused the highest remobilisation to the water, indicating an effective transport of (soluble) Cd over the sediment -water interface via bioirrigation. Lack of the highly hydrophobic and mainly particle-associated BDE-99 below the sediment surface suggests that Marenzelleria caused no significant particle mixing. The addition of various OM types significantly affected the distribution of Cd, but not of BDE-99. There was an interactive effect between bioturbation (species) and OM type, generally showing an increased burial and release of Cd when associated with phytoplankton in the presence of Marenzelleria. Our results emphasise the importance of understanding the complex interactions between ecological (e.g. infaunal feeding and bioturbation activities) and physiochemical processes (contaminant speciation and sorption kinetics) when assessing the fate of contaminants in aquatic ecosystems.

Bioirrigation, on the other hand, increases the flux of solutes, i.e. dissolved compounds in the pore water and over the sediment -water interface (Aller & Aller 1998). The partitioning of a contaminant between the solid and water phase in sediments depends on the contaminant's inherent properties and the biogeochemical state of the sediment. Hydrophobic organic contaminants (HOCs) preferentially adsorb to particulate OM in sediments, and their distribution between phases generally can be calculated based on the physiochemical properties of the compound, such as water solubility and lipophilicity, and the amount of OM in the sediment (Schwarzenbach et al. 2003). The partitioning of metals is strongly affected by the sediment chemical environment, such as pH, redox conditions and the presence of other chemical species (Chapman et al. 1998).

“…Given the growing interest in understanding the changes of physical environment induced by organisms (Statzner, 2012), bed sediment reworking by a variety of animal species acting as zoogeomorphic agents has been extensively studied in the bioturbation research field both for marine and freshwater environments (e.g., macroinvertebrates: Cade´e, 1979;Caradec et al, 2004;Heldman et al, 2011;Marmonier et al, 2012;Zhang et al, 2014;molluscs: Orvain and Sauriau, 2002;Gilbert et al, 2007; crayfish: Statzner et al, 2003a;Statzner and Peltret, 2006;Johnson et al, 2010;mammals: Jones et al, 1994). Among this fauna, many studies have focused on fish as actors of bed surface disturbance in streams (e.g., Flecker, 1996;Flecker and Taylor, 2004;Holtgrieve and Schindler, 2010), given their key role in the flux and transfer of particles and solutes in aquatic ecosystems.…”

-Water temperature is a key parameter that regulates activities of ectotherms (e.g., fish) and has been projected to rise in the future in the context of climate change. Surface sediment disturbance (SSD) is an important function performed by fish that modifies benthic habitat properties and may thus influence ecosystem functioning. However, the link between SSD by fish and temperature remains unexplored. In this study, we experimentally assessed the influence of two contrasted temperatures (10 versus 20 xC) on SSD by three freshwater fish species in aquaria. After 10 days, the total surface disturbed by the species was approximately 2-3 times higher at warm than at cold temperature but the number and area of patches disturbed by the species were not significantly different. The stone loach Barbatula barbatula, a benthic fish species, had a higher SSD activity (i.e., total surface disturbed, number and size of patches disturbed) both at cold and warm temperatures than two cyprinid species, chub Squalius cephalus and sofie Parachondrostoma toxostoma. On average, SSD by B. barbatula resulted in approximately two and three more patches than the cyprinid species at 10 and 20 xC, respectively, and the mean patch area disturbed by B. barbatula was about two times larger than the ones disturbed by the cyprinid species. The total surface disturbed by the cyprinids at warm temperature was roughly equivalent to the surface disturbed by B. barbatula at cold temperature. Our results thus suggest that SSD by fish could increase in future warmed conditions.
