“…The export of silt and clay out of the enclosures with worm addition suggests that tubificid worms induced a resuspension of fine particles, a mechanism that may explain most of our results. In a laboratory experiment using lake sediments, Zhang, Shang, et al (2014) reported that the worm L. hoffmeisteri increased by twofold the quantity of total suspended solids in water column under physical mixing (mimicking a light wind effect on the water column). The selective feeding of tubificid worms on fine particles and their egestion at the sediment surface could engender a surface layer of low density that could be easily flushed out by water turbulence (at low shear stress, McCall & Tevesz, 1982) through wind resuspension (e.g.…”

“…Wavre & Brinkhurst, ; Levinton, ; Mermillod‐Blondin, Gerino, Creuzé des Châtelliers, & Degrange, ; second hypothesis). Nevertheless, we did not have any expectations about the influence of tubificid worms on the algal compartment: On the one hand, turbidity generated by worms may affect the growth of benthic algae (Krantzberg, ; Zhang, Shang, et al., ), but on the other hand, bioturbation may increase nutrient availability (e.g. Mermillod‐Blondin, Nogaro, Datry, Malard, & Gibert, ; Puigagut, Chazarenc, & Comeau, ; Zhang, Liu, Jeppesen, & Taylor, ) and thus stimulate algae.…”

“…Tubificid worms feed selectively on fine particles; they ingest them at depth in sediments and egest faecal pellets rich in water content and organic matter at the sediment surface (McCall & Tevesz, 1982;Rodriguez, Martinez-Madrid, Arrate, & Navarro, 2001). Several field and laboratory experiments highlighted that worms modify the sediment stratigraphy by depositing faecal pellets in the top sediment layer, which are prone to resuspension by water current (Ciutat, Weber, Gérino, & Boudou, 2006;Li et al, 2016;McCall & Tevesz, 1982;Zhang, Shang, He, You, & Fan, 2014). Laboratory experiments also demonstrated that sediment reworking and gallery building by tubificid worms increase water-filled porosity and water exchanges at the water-sediment interface, influencing pore-water chemistry (Anschutz et al, 2012;Krantzberg, 1985;Mermillod-Blondin et al, 2001), organic matter processing (Navel, Mermillod-Blondin, Montuelle, Chauvet, & Marmonier, 2012), nutrient cycling (Chatarpaul, Robinson, & Kaushik, 1980;Nogaro & Burgin, 2014) and sediment habitability for other benthic organisms (Mermillod-Blondin & Lemoine, 2010).…”

Influence of tubificid worms on sediment structure, benthic biofilm and fauna in wetlands: A field enclosure experiment

Bioturbation activities of tubificid worms play a major role in nutrient cycling and microbial processes occurring at water–sediment interfaces of freshwater environments. Nevertheless, evidence of significant contributions of worms to ecosystem functioning largely arises from experiments performed at laboratory scales, because studies exploring the role of tubificid worms in the field are scarce. Therefore, this study aimed to test the influence of tubificid worms on benthic habitat structure and functioning in field experiments. According to literature, we predicted that feeding activities of tubificid worms would increase the percentage of clay and silt particles, the bacterial growth and microbial activities in the top sediment layer. The experiment was performed at the water–sediment interface of a shallow wetland. Enclosures with and without addition of the tubificid worm Limnodrilus hoffmeisteri were used to quantify the influences of tubificid worms on the sedimentary habitat (sediment grain size distribution, water‐filled porosity using microtomography), the biofilm (algal biomass, bacterial abundance, total organic carbon and total nitrogen, microbial enzymatic activity, photosynthetic activity and efficiency of the photosystem II) and the benthic fauna. Measures were performed before worm addition and at the end of the experiment. After 6 weeks, the proportion of fine sediment particles (<63 μm) and the water‐filled porosity were significantly modified by the bioturbation activities of tubificid worms. The bacterial abundance was stimulated by twofold, the microbial hydrolytic activity by +35% and the algal biomass by +40%. The field enclosures with and without L. hoffmeisteri showed differences in benthic invertebrate assemblages, especially for nematodes that were excluded from enclosures with worms. Our results indicate that bioturbation mechanisms and impacts reported from laboratory experiments with tubificid worms are not only significant at a field scale, but also highlight unpredicted interactions with other benthic organisms (autotrophic compartment of the biofilm and invertebrates).

“…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.

“…However, sediment resuspension could occur due to disturbance at water-sediment interface, e.g. due to the presence of benthic invertebrates (Zhang et al, 2014), which may turn the sediment to become a source of contamination to the overlying water. Indeed, a microcosm experiment evaluating the fate and effects of TCS on benthic macroinvertebrates demonstrated that the presence of benthic macroinvertebrates in the microcosms caused significantly higher TCS concentration in the overlying water compared to microcosms without (Chapter 4).…”
