Macroinvertebrates as engineers for bioturbation in freshwater ecosystem

Environmental Science and Pollution Research, 2022
Bioturbation is recognized as a deterministic process that sustains the physicochemical properties of the freshwater ecosystem. Irrigation, ventilation, and particle reworking activities made by biotic components on sediment beds influence the flow of nutrients and transport of particles in the sediment-water interface.

Bioturbation: a fresh look at Darwin's last idea

Trends in Ecology & Evolution, 2006
Bioturbation refers to the biological reworking of soils and sediments, and its importance for soil processes and geomorphology was first realised by Charles Darwin, who devoted his last scientific book to the subject. Here, we review some new insights into the evolutionary and ecological role of bioturbation that would have probably amazed Darwin.

Bioturbation

2011
Definition and introduction Bioturbation refers to particle mixing within unconsolidated sediments through the activities of biological organisms, most commonly at, or close to, the water-sediment interface. The implications of this process go far beyond simply mixing the substrate as sediment particle preservation, food availability, and geochemical ...

Geoacoustic models and bioturbation

Marine Geology, 1980
Abstract Two types of geoacoustic models are used to describe relationships between physical and acoustic properties of unconsolidated marine sediments: simple predictive, and theoretical models. Simple predictive models use the apparent correlation between physical properties of sediments (usually porosity, grain size or density) and acoustic ...

Porosity and Permeability in Bioturbated Sediments

2012
Owing to the textural contrast that commonly exists between matrix and trace fossils, biogenic flow media are common in the rock record. Broadly speaking, the permeability contrast between the matrix and the trace-fossil-affected zones constitutes the most important parameter for characterizing biogenically influenced flow media.
