Bioturbation: a fresh look at Darwin's last idea
Trends in Ecology & Evolution, 2006Bioturbation 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.

Geoacoustic models and bioturbation
Marine Geology, 1980Abstract 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 ...

Bioturbation in eolian deposits
Journal of Sedimentary Research, 1978Abstract Bioturbation traces are very common in the one coastal and 11 inland dune fields we have studied. These fields occur in a variety of geographic settings in both cold and warm climates. The burrowing behavior of selected invertebrates, particularly arthropods such as sand wasps, sand-treader camel crickets, wolf spiders, crane

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 ...

Porosity and Permeability in Bioturbated Sediments
2012Owing 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.

Effects of Bioturbation on Sediment—Seawater Interaction
Marine Geology, 1977Abstract Large gradients of dissolved silica are common in the uppermost layers of abyssal marine sediments. These gradients can be sustained only by an active, continuous supply of dissolved silica from within the sediments. The flux of dissolved silica is approximately equivalent to the total accumulation rate of all siliceous material (including ...

Bioturbation behaviour in two Mediterranean polychaetes
Journal of the Marine Biological Association of the United Kingdom, 2001To evaluate the potential for sediment reworking of two deposit-feeder polychaetes, daily sediment expelled per single worm has been estimated in laboratory experiments on 20 specimens of Nainerislaevigata and 20 of Notomastus latericeus. Both species showed very low values of daily sediment expelled especially when compared to literature data ...

Fungal bioturbation paths in a compact disk
Naturwissenschaften, 2001We report here on bioturbation traces, with micro-dendrite textures, composed of a mixture of altered aluminum and polycarbonate, which have been developed in a common compact disk (CD), destroying information pits. Fungal hyphae proliferated in these deteriorated zones, and Geotrichum-type fungus was isolated from surface-sterilized CD fragments.
