Effects of temperature on in vitro sediment reworking processes by a gallery biodiffusor, the polychaete Neanthes virens [PDF]
, 2004 Temperature-induced variations in bioturbation could affect sediment mixing processes in the marine benthic environment. In this study, sediment reworking by Neanthes virens (Sars), a widely distributed polychaete in muddy sand communities of northern ...

Selectivity of soil constituents by termites in the construction of Brazilian termite mounds [PDF]
Scientia Agricola, 2023 Termites can create structures that alter the physical and chemical properties of soils. In this process, termites are selective about the soil constituents they will use to construct their mounds.

2-D optical quantification of particle reworking activities in marine surface sediments [PDF]
, 2003 Particle and solute transport by faunal activities may significantly influence rates and pathways of organic matter mineralization during early diagenesis in surface sediments. One of the most frequently utilized techniques to quantify benthic biological

Using tsunami deposits to determine the maximum depth of benthic burrowing.
PLoS ONE, 2017 The maximum depth of sediment biomixing is directly related to the vertical extent of post-depositional environmental alteration in the sediment; consequently, it is important to determine the maximum burrowing depth.

Ecology and Evolution, 2021 Different conceptions of disturbance differ in the degree to which they appeal to mechanisms that are general and equivalent, or species‐, functional group‐, or interaction‐specific.

A cost-effective method to quantify biological surface sediment reworking [PDF]
, 2013 We propose a simple and inexpensive method to determine the rate and pattern of surface sediment reworking by benthic organisms. Unlike many existing methods commonly used in bioturbation studies, which usually require sediment sampling, our approach is ...

Bioturbation and porosity gradients [PDF]
Limnology and Oceanography, 1998 Ubiquitous porosity gradients have a potentially important effect on the mixing of particle‐bound tracers, such as 210Pb Mass‐depth coordinates cannot be used to deal with these effects if values of the traditional mixing coefficient, DB are required.

Geosciences, 2021 The presented 3D seismic system operates three transducers (130 kHz) from a stationary lander and allows non-destructive imaging of small-scale objects within the top decimeters of silty sediments, covering a surface area of 0.2 m2.

Influence of nontrophic interactions between benthic invertebrates on river sediment processes: a microcosm study [PDF]
, 2004 The main objective of this study was to measure the impact of benthic invertebrate diversity on river sediment processes. We quantified the effects of interactions between three taxa (asellids, chironomid larvae, and tubificid worms).
