Process in which an organism causes mixing of a sediment. Product of bioturbation is a bioturbate texture.
Disturbances of soils and substrates by an animal or plants which also includes inverebrate burrowing as well as tracks and traces from vertebrates
The disturbance of sediments caused by living organisms as they feed and/or burrow.
disturbance due to organisms moving and burrowing (for example)
Disruption of sediments by feeding and burrowing organisms.
The natural activity of living organisms, such as worms, to move particles and porewater from inside soil or sediment beds toward the surface and circulate them in the upper layers.
Are organisms, mainly worms or crustaceans, that disturb the sediment by burrowing or during feeding. Their activities mix the sediment layers and may cause substantial sediment resuspension.
Reworking of sediments by organisms that burrow and ingest them.
Disturbance of soil through natural causes such as burrowing animals and plant growth.
The reworking of existing sediments by organisms.
disturbance of soft sediment by burrowing creatures
n. The disturbance of sediment by organisms, e.g. burrows, trails, or complete mixing.
Bioturbation is the disturbance of sediment layers by biological activity. It is a significant process on the ocean floor. In that environment, numerous animals such as worms exist by consuming organic matter trapped between sediment grains. Animals like clams burrow through sediment to hide from predators swimming or crawling above the ocean floor. Either activity requires the animals to burrow through the sediment, destroying some of the pre-existing sedimentary features.
In oceanography and limnology, bioturbation is the displacement and mixing of sediment particles by benthic fauna (animals) or flora (plants). The mediators of bioturbation are typically annelid worms (e.g. polychaetes, oligochaetes), bivalves (e.g. mussels, clams), gastropods, holothurians, or any other infaunal or epifaunal organisms. Faunal activities, such as burrowing, ingestion and defecation of sediment grains, construction and maintenance of galleries, and infilling of abandoned dwellings, displace sediment grains and mix the sediment matrix.
