Does an Invasive Bivalve Outperform Its Native Congener in a Heat Wave Scenario? A Laboratory Study Case with Ruditapes decussatus and R. philippinarum

Biology, 2021
Global warming and the subsequent increase in the frequency of temperature anomalies are expected to affect marine and estuarine species’ population dynamics, latitudinal distribution, and fitness, allowing non-native opportunistic species to invade and ...

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.

Disturbance and the (surprising?) role of ecosystem engineering in explaining spatial patterns of non‐native plant establishment

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.

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.

Subsurface and Infaunal Foraminifera of Kemaman- Chukai Mangrove Swamps, East Coast Peninsular Malaysia

Open Quaternary, 2021
This study analysed the distribution and abundance of dead and live (Rose Bengal stained) infaunal foraminifera from three short cores taken at three locations in the mangrove swamps of Kemaman-Chukai, Terengganu, Malaysia.

Laboratory Measurements to Image Endobenthos and Bioturbation with a High-Frequency 3D Seismic Lander

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.

Shell accumulation on seabed due to suspended coastal oyster farming and effects on burrowing capacity of the polychaete Perinereis aibuhitensis

Frontiers in Marine Science, 2023
Mariculture of bivalves (e.g., mussels, scallops, and oysters) is developing rapidly in coastal waters. This process releases shell debris that can accumulate on the seabed under farms.

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.

Radium and Lead Radioisotopes Composition of Sediment and Its Biogeochemical Implication in Polymetallic Nodule Area of Clario-Clipperton Zone

Molecules, 2022
Radioactivity levels of 210Pb and 226Ra were detected in a sediment core obtained using a multi-corer from the polymetallic nodule area inside the Clarion-Clipperton Zone (CCZ), a contract area of the China Ocean Mineral Resources Association (COMR) in ...

Benthic bioturbations weaken the stability of blue carbon storage

National Science Open
Coastal ecosystems are known for their ability to sequester organic carbon (OC), termed “blue carbon”. The molecular composition of dissolved organic matter (DOM) can affect sediment OC content; however, the impact of benthic bioturbation on DOM ...
