Carbon sequestration takes place only if burial rates by sediment are greater than the long term rates of erosion, bioturbation, and decomposition.
22.
A-horizons may also be the result of a combination of soil bioturbation and surface processes that winnow fine particles from biologically mounded topsoil.
23.
It is also important to figure in bioturbation and the constant mixing of this material which can change the relative importance of each respiration pathway.
24.
In geology, mottled refers to a patchy / blotch texture of alteration or interbedding, commonly found in limestone and commonly caused by bioturbation.
25.
However, bioturbation, including burrowing animals, frost cracks, etc ., can reverse the structural timeline of an earthen mound such as Serpent Mound.
26.
Bioturbation by burrowing animals results in soil landscapes that are both polygenetic ( having many causes ) and polytemporal ( having been created at many times ).
27.
Besides exclusion and bioturbation effects of aerobic organisms, Fenchel and Riedl ( 1970 ) pioneered investigations into an unusual fauna inhabiting the suboxic regions of sediment.
28.
Fossils represented in the Walcott Rust quarry beds reflect a shelf community that developed during times of rather low net sedimentation and minimal bioturbation of the bottom.
29.
As it formed in an offshore position, in a subtidal wave-influenced environment, bioturbation is important and is translated by cross-bedding structures.
30.
Therefore, sea cucumbers play a major role in the biological processing of the sea bed ( bioturbation, purge, homogenization of the substratum etc . ).
