Effects of temperature on in vitro sediment reworking processes by a gallery biodiffusor, the polychaete Neanthes virens [PDF]

, 2004
Temperature-induced variations in bioturbation could affect sediment mixing processes in the marine benthic environment. In this study, sediment reworking by Neanthes virens (Sars), a widely distributed polychaete in muddy sand communities of northern ...

Benthic bioturbations weaken the stability of blue carbon storage

National Science Open
Coastal ecosystems are known for their ability to sequester organic carbon (OC), termed “blue carbon”. The molecular composition of dissolved organic matter (DOM) can affect sediment OC content; however, the impact of benthic bioturbation on DOM ...

In situ organism-sediment interactions: Bioturbation and biogeochemistry in a highly depositional estuary.

PLoS ONE, 2017
Organic matter (OM) production and degradation is important in coastal estuaries, and OM fate is strongly influenced by the coupled interactions of bioturbation and biogeochemistry.

Hindcasting Ecosystem Functioning Change in an Anthropogenized Estuary: Implications for an Era of Global Change

Frontiers in Marine Science, 2021
Understanding how altered hydrodynamics related to climate change and anthropogenic modifications affect ecosystem integrity of shallow coastal soft-sediment environments requires a sound integration of how species populations influence ecosystem ...

Benzo(a)pyrene inhibits the role of the bioturbator Tubifex tubifex in river sediment biogeochemistry [PDF]

, 2013
The interactions between invertebrates and micro-organisms living in streambed sediments often play key roles in the regulation of nutrient and organic matter fluxes in aquatic ecosystems.

Bioturbation and porosity gradients [PDF]

Limnology and Oceanography, 1998
Ubiquitous porosity gradients have a potentially important effect on the mixing of particle‐bound tracers, such as 210Pb Mass‐depth coordinates cannot be used to deal with these effects if values of the traditional mixing coefficient, DB are required.

Influence of nontrophic interactions between benthic invertebrates on river sediment processes: a microcosm study [PDF]

, 2004
The main objective of this study was to measure the impact of benthic invertebrate diversity on river sediment processes. We quantified the effects of interactions between three taxa (asellids, chironomid larvae, and tubificid worms).

Reshaping perspectives of deep-sea benthic function

Frontiers in Marine Science
Bioturbation is a key ecosystem function with a fundamental role in mediating major biogeochemical cycles. The intensity and depth of bioturbation is influenced by the taxa present, which is often a function of food supply.

Early Palaeozoic ocean anoxia and global warming driven by the evolution of shallow burrowing

Nature Communications, 2018
The extent to which the onset of bioturbation affected global biogeochemistry during the Palaeozoic remains unclear. Here, the authors integrate bioturbation into the COPSE model, compare output with geochemical proxies, and suggest shallow burrowing ...
