bioturbation

Bioturbation is common and many fossils can be found here.

However, bioturbation by crabs may also have a positive effect.

Bioturbation can accelerate this process by up to a factor of ten.

Modern research has provided further insight into the evolutionary and ecological role of bioturbation.

Bioturbation is central to the soil biomantle concept formulated in 1990.

Where it occurs, Aphaenogaster bioturbation is an important soil and landscape process.

Fossil sites with bioturbation do not leave traces of soft-bodied animals.

Since wave action is heavier, bioturbation is not likely.

Darwin would be proud: Bioturbation, dynamic denudation, and the power of theory in science.

Their role in bioturbation on the Khorat Plateau is under investigation.

Fresh wet surface display horizontal lamina, ripples and evidence of bioturbation.

Varve formation needs the absence of bioturbation (lake bottom disturbed by animals).

Paleoecological studies of soils places the origin for bioturbation to a time before the Cambrian period.

The term didn't exist before 1952, when bioturbation was coined to aid in ichnological assessments.

Examples include burrows and various expressions of bioturbation.

And what about ongoing bioturbation, the disturbance caused by roots and rodents?

Deposited in still waters, the unit lacks bioturbation, perhaps indicating anoxic conditions.

Microbial exudates act to maintain soil structure, and earthworms are important in bioturbation.

The difference here is that dunes on a barrier island typically contain vegetation roots and marine bioturbation.

The amphipod has an important role in bioturbation (mixing and oxidating the bottom sediment).

Bioturbation is defined as the disturbance and mixing of sediments by benthic organisms.

In some places fossils or bioturbation occur.

This is helped by the extracting and reworking processes of phosphatic particles or bioturbation.

Bioturbation was initially unrecognized as a pedogenic force.

As organisms feed and migrate through soils they physically displace materials, an ecological process called bioturbation.
