Bioturbation 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.

Bioturbation is the reworking of soils and sediments by animals or plants. Its effects include changing the texture of sediments ( diagenesis ), bioirrigation , and displacement of microorganisms and non-living particles. Common bioturbators include annelids (ringed worms) such as oligochaetes and Spirobranchus giganteus , bivalves like mussels and clams , gastropods , holothurians , or any ...

Bioturbation is defined as the reworking of and by animals or plants. These include burrowing, ingestion and defecation of sediment grains. Bioturbating activities have a profound effect on the environment and are thought to be a primary driver of biodiversity. The formal study of bioturbation began in the 1800s by Charles Darwin experimenting in his garden.

Bioturbation refers to the physical effects of animals on their substratum . It typically takes two forms in marine ecosystems: particle reworking and ventilation [ 1 ]. These two processes, which primarily result from the activities of benthic (usually burrowing) macroinvertebrates, may have significant ecological implications [ 1 – 4 ].

3/1/2006 · In slow-moving streams, as in marine ecosystems with soft sediments, bioturbation can be an important source of soft-sediment mixing (Peterson 1979). This bioturbation aerates sediments, changes sediment nutrient cycling, increases nutrient recycling to the water column, and changes benthic community composition (Covich et al. 1999).

Pedogenesis (from the Greek pedo-, or pedon, meaning 'soil, earth,' and genesis, meaning 'origin, birth') (also termed soil development, soil evolution, soil formation, and soil genesis) is the process of soil formation as regulated by the effects of place, environment, and history. Biogeochemical processes act to both create and destroy order within soils.
