Bioturbation experiments in the Venice Lagoon [PDF]

open access: yesHydrobiologia, 2003
Short experiments (14–21 days) were carried out during autumn 1998 and spring 1999 at one selected site of the Venice Lagoon to measure bioturbation activities and mixing rates, as well as to obtain quantitative information on benthos functionality ...

Bioturbation in the hadal zone. [PDF]

open access: yesNat Commun
Abstract The hadal zone, >6 km deep, remains one of the least understood ecosystems on Earth. We address bioturbational structures in sediment cores from depths exceeding 7.5 km, collected during the IODP Expedition 386 in the Japan Trench.

Raised water temperature enhances benthopelagic links via intensified bioturbation and benthos-mediated nutrient cycling [PDF]

open access: yesPeerJ
Sediment reworking by benthic infauna, namely bioturbation, is of pivotal importance in expansive soft-sediment environments such as the Wadden Sea. Bioturbating fauna facilitate ecosystem functions such as bentho-pelagic coupling and sediment nutrient ...

Benthic ecosystem functioning under climate change: modelling the bioturbation potential for benthic key species in the southern North Sea [PDF]

open access: yesPeerJ, 2022
Climate change affects the marine environment on many levels with profound consequences for numerous biological, chemical, and physical processes. Benthic bioturbation is one of the most relevant and significant processes for benthic-pelagic coupling and

Quantitative characterization of ichnology based on CT scan: A case study of Mackay-Ⅲ oil sands, Canada

open access: yes地质科技通报, 2021
Based on high-resolution core photos, CT scan pictures, and well logging, the classification, features and spatial distributions of trace fossils in McMurray Formation, Lower Cretaceous, Mackay-III oil sands, Canada, were characterized quantitatively ...

Assessing the expansion of the Cambrian Agronomic Revolution into fan-delta environments

open access: yesScientific Reports, 2022
The intensity, extent, and ecosystem-level impact of bioturbation (i.e. Agronomic Revolution) at the dawn of the Phanerozoic is a hotly debated issue.

Mammalian bioturbation amplifies rates of both hillslope sediment erosion and accumulation along the Chilean climate gradient [PDF]

open access: yesBiogeosciences, 2023
Animal burrowing activity affects soil texture, bulk density, soil water content, and redistribution of nutrients. All of these parameters in turn influence sediment redistribution, which shapes the earth's surface.

Bioturbation Intensity Modifies the Sediment Microbiome and Biochemistry and Supports Plant Growth in an Arid Mangrove System

open access: yesMicrobiology Spectrum, 2022
In intertidal systems, the type and role of interactions among sediment microorganisms, animals, plants and abiotic factors are complex and not well understood. Such interactions are known to promote nutrient provision and cycling, and their dynamics and

Digging Deeper: Bioturbation increases the preserved sulfur isotope fractionation

open access: yesFrontiers in Marine Science, 2023
Bioturbation enhances mixing between the seafloor and overlying ocean due to changes the redox state of the sediment and influences the biogeochemical cycling of redox-sensitive elements such as sulfur. Before the widespread appearance of burrowing fauna

A lattice-automaton bioturbation simulator with coupled physics, chemistry, and biology in marine sediments (eLABS v0.2) [PDF]

open access: yesGeoscientific Model Development, 2019
Seawater–sediment interaction is a crucial factor in carbon and nutrient cycling on a wide range of spatial and temporal scales. This interaction is mediated not just through geochemistry but also via biology.
