Deep-Sea Echinoid Trails and Seafloor Nutrient Distribution: Present and Past Implications

Frontiers in Marine Science, 2022
The movement patterns of deep-sea bioturbational fauna are believed to be the result of the organism’s interactive response to the perceived spatial distribution of nutritional resources on the seafloor.

In situ organism-sediment interactions: Bioturbation and biogeochemistry in a highly depositional estuary.

PLoS ONE, 2017
Organic matter (OM) production and degradation is important in coastal estuaries, and OM fate is strongly influenced by the coupled interactions of bioturbation and biogeochemistry.

Hindcasting Ecosystem Functioning Change in an Anthropogenized Estuary: Implications for an Era of Global Change

Frontiers in Marine Science, 2021
Understanding how altered hydrodynamics related to climate change and anthropogenic modifications affect ecosystem integrity of shallow coastal soft-sediment environments requires a sound integration of how species populations influence ecosystem ...

Early Palaeozoic ocean anoxia and global warming driven by the evolution of shallow burrowing

Nature Communications, 2018
The extent to which the onset of bioturbation affected global biogeochemistry during the Palaeozoic remains unclear. Here, the authors integrate bioturbation into the COPSE model, compare output with geochemical proxies, and suggest shallow burrowing ...

Reshaping perspectives of deep-sea benthic function

Frontiers in Marine Science
Bioturbation is a key ecosystem function with a fundamental role in mediating major biogeochemical cycles. The intensity and depth of bioturbation is influenced by the taxa present, which is often a function of food supply.

Interpreting a Legacy Fossil Assemblage Excavated From Waribruk (New Guinea II Cave), GunaiKurnai Aboriginal Country, Snowy River National Park, Southeastern Australia

Archaeology in Oceania, EarlyView.
ABSTRACT In this paper we report on faunal remains recovered from a legacy archaeological excavation undertaken in the rockshelter entrance of Waribruk (New Guinea II Cave), a GunaiKurnai site located on the west bank of the Snowy River, East Gippsland, southeastern Australia.

Benthic Invertebrate Bioturbation Activity Determines Species Specific Sensitivity to Sediment Contamination

Frontiers in Environmental Science, 2017
Bioturbation activity of sediment-dwelling organisms promotes the release of contaminants across the benthic-pelagic ecosystem boundary, thereby affecting the exposure to and uptake of sediment associated contaminants at the sediment-water interface by ...

A Geomorphometric Approach to Estimate the Deterioration of Earthen Archaeological Sites by Rainfall and Diffusion Processes: The Huaca Chornancap (Eighth–14th Century ad), Lambayeque, Peru

Archaeological Prospection, EarlyView.
ABSTRACT Rain‐induced erosion processes can severely damage Earthen archaeological sites. Huaca Chornancap (HCH; eighth–14th century ad) is a platform located in the Lambayeque region (Peru) exposed to seasonal rain due to El Niño Southern Oscillation (ENSO).

Seasonally Intensified Mud Shrimp Bioturbation Hinders Seagrass Restoration

Journal of Marine Science and Engineering
Understanding how disturbances affect marine foundation species is critical for enhancing the success of coastal ecosystem restoration. Extreme bioturbation by burrowing animals is increasingly impacting coastal vegetated habitats worldwide, with the ...

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

Archaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...
