Geobiology: Machine learning puts bioturbation on the map
Current BiologyBioturbation, the mixing of sediment through the actions of organisms, is a crucial ecosystem engineering process that controls biogeochemical cycles and helps structure marine ecosystems. Machine learning is helping to develop global maps of the intensity and depth of bioturbation.

Shale fissility: relation to bioturbation
Sedimentology, 1974Fissility in shales appears directly related to the parallel orientation of mineral grains in the rock fabric. In two shale sequences examined, fissility increases along a gradient of decreasing bioturbation. Normal marine mudrocks should be characterized by lack of fissility due to the randomized fabric produced by bioturbation, while azoic marine ...

Bioturbation in a Dysaerobic, Bathyal Basin
1985Abstract Oxygen-deficient waters at the bathyal depths of the Santa Cruz Basin in the California Continental Borderland create harsh conditions for marine life. A feeding strategy approach is used for descriptions of the life habits (i.e., the organism's motility and its living position with respect to the substrate) of benthic fauna ...

Die Synökologie der Bioturbation
1999Die vorherigen Kapitel beschaftigten sich mit der Autokologie ausgewahlter Arten. Sedimente werden jedoch selten nur durch eine Art allein aufgearbeitet. Haufiger wird ein endobenthischer Lebensraum von einer Gemeinschaft in viele okologische Nischen unterteilt, die jeweils durch eine, auf eine besondere Lebensweise spezialisierte, Art besetzt werden ...
