Erosion and habitat loss on intertidal flats are increasingly fought through large-scale sediment nourishment. Yet the impact of nourishment on short-term bed-level dynamics remains poorly quantified. Daily erosion–accretion events shape the immediate physical environment experienced by benthic infauna: repeated burial and re-exposure set the physical bounds of the ecological niche, making bed-level dynamics a key indicator of...

Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long‐term, representative information on key fish populations and habitats to inform management and policy. Underwater fish observation (UFObs) techniques, such as Underwater Visual Census (UVC), stereo‐Baited Remote Underwater Video (stereo‐BRUV) and Remotely Operated Vehicles (ROVs), play...

Marine sterols from brown seaweeds, particularly fucosterol and its oxidized derivative saringosterol, have shown therapeutic potential for Alzheimer’s disease (AD) and cardiovascular diseases. Here, we aimed to elucidate the cellular and in vivo mechanisms underlying their beneficial effects. In human HepG2 hepatocytes and CCF-STTG1 astrocytoma cells, we assessed liver x receptor (LXRα /LXRβ) activation, sterol uptake, and ef...

Escalating high‐energy hydrodynamic events, like storms, represent a significant manifestation of global climate change, causing detrimental impacts on various ecosystems and potentially triggering thresholds that result in abrupt shifts in ecosystem states. Despite the potential of such thresholds, few studies have explicitly addressed them. This gap is particularly notable for subtidal ecosystems due to technological challen...

Tidal flats are valuable ecosystems that depend on complex biogeomorphic processes between organisms and sediment transport. Climate change has led to a rise in extreme weather events, such as storms. This, in turn, has increased sediment dynamics and created risks for the benthic communities inhabiting tidal flats. However, replicating sediment disturbances caused by extreme weather is difficult. To overcome this, we used the...

Striking large‐scale spatial patterns in ecosystems, generated by self‐organization through biotic and abiotic feedback processes, influence ecosystem functioning and response to global environmental change. A remarkable example of this are the regular ridge‐runnel patterns found on tidal flats, which play an important role in mudflat‐marsh transitions. Yet the mechanisms driving their formation, and whether they are abiotic o...
