Abstract Aquatic ecologists face challenges in identifying the general rules of functioning ecosystems. A common framework, including freshwater, marine, benthic, and pelagic ecologists, is needed to bridge communication gaps foster knowledge sharing. This framework should transcend local specificities taxonomy order provide a ground shareable tools address scientific challenges. Here, we advocate use functional trait‐based approaches (FTBAs) for aquatic propose concrete paths go forward....
Significance Humans are exposed to toxic methylmercury mainly by consuming marine fish. New environmental policies under the Minamata Convention rely on a yet-poorly-known understanding of how mercury emissions translate into fish levels. Here, we provide first detailed map concentrations from skipjack tuna across Pacific. Our study shows that natural functioning global ocean has an important influence concentrations, specifically in relation depth at which peak water column. However, inputs...
Abstract Aim β diversity and its linkages with ecosystem functioning remain poorly documented. This impedes our capacity to predict biodiversity changes how they affect at scales relevant for conservation. Here, we address the functional implications of ongoing seafloor by characterizing regional scale taxonomic α diversities benthic habitats currently threatened biotic homogenization. Location Western Europe. Methods Combining a trait‐based approach community monitoring data covering 7‐year...
Humans are exposed to toxic methylmercury mainly by consuming marine fish. While reducing mercury emissions and releases aims protect human health, it is unclear how this affects concentrations in seawater biota. We compiled existing newly acquired tropical tunas from the global ocean explore multidecadal variability between 1971 2022. show strong inter-annual of tuna at scale, after correcting for bioaccumulation effects. found increasing skipjack late 1990s northwestern Pacific, likely...
Long‐term monitoring programs are fundamental to detect changes in ecosystem health and understand ecological processes. In the current context of increasing anthropogenic threats on marine ecosystems, understanding dynamics response communities becomes essential. We used data collected over 14 years REBENT benthic coastal invertebrates program, at a regional scale North‐East Atlantic, covering total 26 sites 979 taxa. Four distinct habitats were studied: two biogenic associated with...
Habitat complexity (HC) promotes species richness and abundance. Aquatic environments are faced with intense pressures that threaten the 3D structure of seafloor, cascading effects on ecosystem functioning biodiversity. Maerl or rhodolith beds marine biogenic habitats created by few free‐living non‐geniculate coralline algae aggregate form complex structures. Although their high biodiversity has been attributed to HC provided algal nodules, mechanisms through which modification affect...
In the absence of an immune response from host, intramuscular (IM) injection recombinant adeno-associated virus (rAAV) results in permanent expression transgene mouse to primate models. However, recent gene transfer studies into animal models and humans indicate that risk and/or capsid-specific responses occurs depends on multiple factors. Among these factors, route delivery is important, although poorly addressed large Here, we compare IM drug-free regional intravenous (RI) deliveries rAAV...
Abstract Håkon Mosby mud volcano (HMMV) is one of the most active and studied seep sites in European waters. Many authors have described its thermal activity, dynamic flows, geochemical microbial processes. It characterised by a concentric zonation successive biogenic habitats related to an activity gradient from centre periphery. Around central area covered white grey mats occur among areas bare sediment, whereas siboglinid tubeworm fields Sclerolinum contortum and/or Oligobrachia...
Abstract Polyphenols exert a large range of beneficial effects in the prevention age-related diseases. We sought to determine whether an extract olive and grape seed standardized according hydroxytyrosol (HT) procyanidins (PCy) content, exerts preventive anti-osteoathritic effects. To this aim, we evaluated HT/PCy mix could (i) have vitro anti-inflammatory chondroprotective actions, (ii) anti-osteoarthritis two post-traumatic animal models (iii) retain its bioactivity after oral...
Digestive microbiota provide a wide range of beneficial effects on host physiology and are therefore likely to play key role in marine intertidal bivalve ability acclimatize the zone. This study investigated effect levels digestive bacterial oysters (Crassostrea gigas) clams (Ruditapes philippinarum), two bivalves with different ecological niches. Based 16S rRNA region sequencing, glands, seawater sediments harbored specific communities, dominated by operational taxonomic units assigned...
Abstract Worldwide, ecosystems are suffering important taxonomic and functional modifications in response to anthropogenic disturbances, operating at multiple spatial temporal scales. Awareness on biodiversity losses has led the adoption of conservation policies development programs devoted restoration terrestrial, freshwater, marine ecosystems. The assessment ecological health requires measuring characterizing or degradation dynamics their consequences quality with respect reference...

Maerl beds are ecologically important marine biogenic habitats founded on a few species of free-living coralline algae that aggregate and form highly complex rhodoliths. The high biodiversity found in these have been mainly justified by the structural complexity they provide. However, attempts to quantify this made. distribution, density, rhodolith growth forms, shapes vary with environmental conditions. Hydrodynamics depth shown drive morphology.
