“…In lentic waters, turbidity could be hastened and concentrations in nutrients and organic material higher due to the resuspension of sediments to the water column through bioturbation by fish (e.g., Breukelaar et al, 1994;Matsuzaki et al, 2009), resulting subsequently in phytoplankton blooming and water eutrophication, already enhanced by warming (Jeppesen et al, 2010). Changes in community composition (Matsuzaki et al, 2009) and vertical distribution of benthic fauna (Persson and Svensson, 2006b) due to predation by benthivorous fish may also impact nutrients fluxes as well as the incorporation of organic matter into the benthic food web (Maire et al, 2010), especially at higher temperatures (Zhang et al, 2013). To conclude, given that benthic foraging is a common feeding behaviour in freshwater environments observed all year round and that it appears a substantial zoogeomorphic mechanism (Pledger et al, 2014), SSD by fish should not be overlooked in future research assessing the potential impacts of climate change on zoogeomorphology.…”

-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.

“…And the "Ventilating" behavior improves water exchange and accelerates the flux of certain solutes, such as oxygen, carbon, nitrogen, and other nutrients, at the sedimentwater interface (Forster and Graf, 1995;Van Hoey, 2006;Duport et al, 2007;Na et al, 2008;Turek and Hoellein, 2015;Pascal et al, 2019). Substance flux tend to increase with temperature and the density of benthic animals at the sediment-water interface (Mahl et al, 2009;Zhang et al, 2013). However, bioirrigation-driven substance flux may reach a stable level at the individual level.…”

“…Bioturbation encompasses two distinct processes, namely sediment reworking (i.e., the movements of sediment particles and associated organic matter) and burrow ventilation, which causes bioirrigation (i.e., the exchange of water and solute between the overlying water column and porewater) (Pascal et al, 2019). The ecological functions of bioturbation have been well studied (Zhang et al, 2013;Yazdani Foshtomi et al, 2018;Mustajärvi et al, 2019), some of which showed that the bioturbation could accelerate the biogeochemistry process of the sediment. Infauna perform bioturbation through daily activities, such as feeding, excretion, burrowing, and movement; these activities strongly affect sediment biogeochemistry (Duport et al, 2006;Mustajärvi et al, 2019).…”

Bioirrigation is a process corresponding to animal-induced transport of porewater solute or exchange between interstitial and overlying waters. How and why the burrowing macrobenthos complete this process remain unclear. Here, we used two infaunal-behavior observation devices to investigate the ventilation behaviors of the benthic polychaete Perinereis aibuhitensis Grube, a species that is widespread along the Asian coast with a wide temperature range, at various temperatures (5°C, 10°C, 15°C, 20°C, and 25°C). The two typical movement behaviors of P. aibuhitensis, axial crawling and radial undulation, as well as associated parameters, were delimited and quantified. We found that the radial undulation frequency of P. aibuhitensis and the associated pumping rate (PR) increased significantly with temperature (T, 5-25°C); this relationship can be described by the regression equation PR = −0.0067T2 + 0.29T - 0.52 (R2 = 0.749, P < 0.05; n = 15). The relationship between axial crawling velocity (ACV) and temperature (T, 5-25°C) can be expressed by the regression equation ACV = -0.0001T3 + 0.0059T2 - 0.063T + 0.28 (R2 = 0.997, P<0.05; n = 15). In general, pumping efficiency increased as temperature decreased, implying that the polychaete increasingly conserved energy at lower temperatures. Peak pumping volume (4.36 L d-1) was observed at 25°C, as a result of radial undulations. Thus, we concluded that radial undulation was the primary movement that led to bioirrigation. The dissolved oxygen demand was the key factor driving the initiation of radial undulation, and the specific aim of radial undulation was to increase oxygen availability by pumping new seawater into the burrow. Thus, radial undulation is critical for polychaete survival. The dissolved oxygen threshold level at which pumping was initiated increased with temperature, suggesting more energy conserved at lower temperatures. This pumping strategy of P. aibuhitensis is consistent with optimality theory, and is here designated the “optimal dissolved oxygen obtainment strategy”.

“…Temperature, which may increase bacterial metabolism, and bioturbation are parameters that initially affect the oxygen availability in sediments, thus indirectly conditioning diagenetic processes (Kristensen et al, 1992;Sundby, 2006;Ferreira, 2010;Zhang et al, 2013). In the Patos Lagoon estuary, Southern Brazil, oxygen availability in sediments is strongly associated with local hydrodynamics.…”

Sulfate reduction and alterability of sulfur species in sediments of an estuary with irregular hydrological regime The irregular hydrological regime in Patos Lagoon estuary has been suggested as having a distinctive influence on sulfur speciation in sediments. We performed an investigation for different prolonged hydrological conditions focusing on the distribution of sulfides (acid volatile sulfide (AVS), chromium reducible sulfide (CRS), and FreeS 2-) in sediment cores from salt marsh and non-vegetated shallow zone. Significant differences in sulfides content and distribution between the different hydrological periods were found. The predominance of more reducing conditions was observed during the freshwater period. It reflects a higher total reducible inorganic sulfur (TRIS) content in this period, with a great accumulation of AVS in sediments (> 100 mg kg-1). In the maximum salinity period, more oxidizing conditions prevailed, which significantly decreased the concentrations of metastable sulfides. The intense bioirrigation process exerts control over sulfide formation and distribution, which is as important as that exerted by the variations of the hydrological regime.
