“…Regionally-derived BPc maps for each area can be converted to benthic ecosystem functioning maps, applicable for management purposes, as BPc may serve as proxy for estimates of spatial distribution of geochemical fluxes and nutrient cycling (Snelgrove et al, 2014;Gogina et al, 2018).…”

“…The metric can be useful in this way, but care needs to be taken for its appropriate use and resulting conclusions, as its utility depends on whether or not it fits the functional data (e.g. Kristensen et al, 2012;Queirós et al, 2015;Gogina et al, 2018). For instance, BPc does not always fit the data on nutrient fluxes: in cases it does, one important explanation can again be that the index reflects a process (such as particle displacement) that substantially contributes to the transport process.…”

Bioturbation is one of the key mediators of biogeochemical processes in benthic habitats that can have a high contribution to seafloor functioning and benthic pelagic coupling in coastal waters. Previous studies on bioturbation were limited to point locations and extrapolations in single regions, but have not accounted for regional differences under changing environmental conditions, though there are indications that species contributions will differ across regions or with biotic and abiotic context. To capture those differences and assess global patterns and commonalities, multi-regional analyses are imperative. Here for the first time, bioturbation potential (BPc), a functional indicator of benthic community bioturbation, was estimated based on macrofauna data from four regions (i.e. German Baltic Sea, German North Sea, Belgian part of the North Sea and the Eastern English Channel). For each region and sediment type we identified key species contributing to BPc. Comparison within and across regions demonstrated regional differences, and both overlap and mismatch between species that are functionally important and those that are dominant in biomass. Knowledge on the functionally important species is crucial when management objectives include the protection of certain ecosystem functions. Available environmental layers were used as predictors to model the spatial distribution of BPc for each area and to explore the underlying drivers of differences. Random forest models were trained using as response variables either i) BPc initially calculated per station; or ii) BPpthe species-specific contribution to BPcfor key species Please note that this is an author-produced PDF of an article accepted for publication following peer review.

Maps of BPc distribution predicted by random forest were compared with those generated using natural neighbour interpolation. Overall, derived BPc values increased towards the German parts of the North and Baltic Seas. The relevance of BPc for ecosystem processes and functions, however, vary with biotic and abiotic settings. Results revealed a strong association of BPc with species diversity and region, but less with sediment grain size. A large range of BPc occurred when species richness was low. This suggests that the provisioning of high bioturbation activity is possible also under low diversity, where it is vulnerable due to reduced resilience. The executed multi-regional analysis allowed identifying regional differences in performance of macrofauna, suggesting the need for region-specific conservation and management strategies. Highlights ► First multi-regional analysis of macrofauna community bioturbation potential (BPc). ► Functionally important key species differ regionally and between sediments. ► Overall BPc values decreased from the Baltic Sea towards Eastern English Channel. ► Relevance of BPc for ecosystem f...

“…In particular, the macrozoobenthic organisms disrupt and remix the sediment with their moving, feeding and respiration activities in a process called bioturbation (Meysman, et al, 2006;Kristensen, et al, 2012). Bioturbation alters the bottom sediment composition, geochemistry and erodibility (Le Hir, et al, 2007;Sandford, 2008;Gogina, et al, 2018;Li, et al, 2019). It happens at a local scale, but the effects may be important for broader landscape processes (Widdows & Brinsley, 2002;Bentley Sr, et al, 2014;Walles, et al, 2015).…”

“…Short-term experiments with reconstructed sediments therefore cannot fully reproduce what happens in situ, since the development of bacteria communities along burrows may take weeks and may undergo variations along the life cycle of burrowers [23]. To overcome such limitations, an alternative approach is to collect and incubate undisturbed cores with natural abundance and composition of macrofauna [24][25][26]. A large number of replicate cores can be incubated and sieved at the end of measurements in order to retrieve macrofauna and analyze relationships among macrofauna and biogeochemical processes a posteriori.…”

Coastal lagoons display a wide range of physico-chemical conditions that shape benthic macrofauna communities. In turn, benthic macrofauna affects a wide array of biogeochemical processes as a consequence of feeding, bioirrigation, ventilation, and excretion activities. In this work, we have measured benthic respiration and solute fluxes in intact sediment cores with natural macrofauna communities collected from four distinct areas within the Sacca di Goro Lagoon (NE Adriatic Sea). The macrofauna community was characterized at the end of the incubations. Redundancy analysis (RDA) was used to quantify and test the interactions between the dominant macrofauna species and solute fluxes. Moreover, the relevance of macrofauna as driver of benthic nitrogen (N) redundancy analysis revealed that up to 66% of the benthic fluxes and metabolism variance was explained by macrofauna microbial-mediated N processes. Nitrification was stimulated by the presence of shallow (corophiids) in combination with deep burrowers (spionids, oligochaetes) or ammonium-excreting clams. Deep burrowers and clams increase ammonium availability in burrows actively ventilated by corophiids, which creates optimal conditions to nitrifiers. However, the stimulatory effect of burrowing macrofauna on nitrification does not necessarily result in higher denitrification as processes are spatially separated.
