Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

An open source simulation model for soil and sediment bioturbation. [PDF]
PLoS ONE, 2011 Bioturbation is one of the most widespread forms of ecological engineering and has significant implications for the structure and functioning of ecosystems, yet our understanding of the processes involved in biotic mixing remains incomplete.

Elle s’oppose à l’entrainement par l’eau des solutés et des particules qu’elle remonte vers le haut, vers les racines. La bioturbation mélange

Simulated wild boar bioturbation increases the stability of forest soil carbon [PDF]
Biogeosciences, 2019 Most forest soils are characterised by a steep carbon gradient from the forest floor to the mineral soil, indicating that carbon is prevented from entry into the soil.

Growth Performance of Varieties of Bean (Phaseolus vulgaris) Seedlings in Earthworm-Bioturbated Soil and Crab-Bioturbated Soil [PDF]
Iranica Journal of Energy and Environment, 2023 Earthworms and crabs are known to influence the physicochemical state of their respective soil habitats through their bioturbation actions. While earthworm-bioturbated soils have been well documented to positively affect plant growth, not much is known ...

Organism-sediment interactions govern post-hypoxia recovery of ecosystem functioning [PDF]
, 2012 Hypoxia represents one of the major causes of biodiversity and ecosystem functioning loss for coastal waters. Since eutrophication-induced hypoxic events are becoming increasingly frequent and intense, understanding the response of ecosystems to hypoxia ...

Lethaia, EarlyView., 2021 Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Bioturbation and the δ56Fe signature of dissolved iron fluxes from marine sediments
Royal Society Open Science, 2023 We developed a reaction-transport model capable of tracing iron isotopes in marine sediments to quantify the influence of bioturbation on the isotopic signature of the benthic dissolved (DFe) flux.

Cadmium transport in sediments by tubificid bioturbation: An assessment of model complexity [PDF]
, 2006 Biogeochemistry of metals in aquatic sediments is strongly influenced by bioturbation. To determine the effects of biological transport on cadmium distribution in freshwater sediments, a bioturbation model is explored that describes the conveyor-belt ...
