Red algae of the genus Laurencia are known to biosynthesize and secrete an immense variety secondary metabolites possessing a spectrum biological activities against bacteria, invertebrates mammalian cell lines. Following rigorous cross-species screening process, herein we report antifouling potential 25 derived from species Laurencia, as well thorough evaluation ecotoxicity selected non-target marine arthropods vertebrate A number these exhibited potent activity performed in all tests. Our...
Reproduction in barnacles relies on chemical cues that guide their gregarious settlement. These have been pinned down to several sources of settlement pheromones, one which is a protein termed Settlement-Inducing Protein Complex (SIPC), large glycoprotein acting as pheromone induce larval and an adhesive the surface exploration by cyprids. Settlement assays laboratory conditions with Amphibalanus (=Balanus) amphitrite cyprids presence SIPC showed exhibit preference behaviour at lower...
Globally, marine heatwave frequency, intensity, and duration are on the rise, posing a significant threat to plankton communities, foundational elements of food web. This study investigates ecological physiological responses temperate community in Thau lagoon, north-western Mediterranean, simulated +3°C ten-day followed by post-heatwave period in-situ mesocosms. Our analyses encompassed zooplankton grazing, production, composition water sediment traps, as well oxidative stress anti-oxidant...
To better identify the responses of phytoplankton blooms to warming conditions as expected in a climate change context, an situ mesocosm experiment was carried out coastal Mediterranean lagoon (Thau Lagoon, South France) April 2018. Our objective assess both direct and indirect effects on phytoplankton, particularly those mediated by top-down control. Four treatments were applied: 1) natural planktonic community with ambient water temperature (C); 2) at +3°C elevated (T); 3) exclusion larger...
The Mediterranean Sea has been sampled irregularly by research vessels in the past, mostly national expeditions regional waters. To monitor hydrographic, biogeochemical and circulation changes Sea, a systematic repeat oceanographic survey programme called Med-SHIP was recommended Science Commission (CIESM) 2011, as part of Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP). consists zonal meridional surveys with different frequencies, where comprehensive physical...
Marine microbial eukaryotes play crucial roles in water-column ecosystems; however, there are regional gaps the investigation of natural eukaryote communities, and uncertainties concerning their distribution persevere. This study combined 18S rRNA metabarcoding, biomass measurements statistical analyses multiple environmental variables to examine planktonic at different sites water layers ultra-oligotrophic Eastern Mediterranean Sea (Western Levantine Basin). Our results showed that...
Atmospheric deposition is assumed to stimulate heterotrophic processes in highly oligotrophic marine systems, controlling the dynamics and trophic efficiency of planktonic food webs, expected be influenced by climate change. During an 8-day mesocosm experiment, we investigated channeling, Saharan dust (SD) mixed aerosols (A) effects on microplankton, up copepod level ultra-oligotrophic Eastern Mediterranean waters. Using mesocosms with SD A treatments, feeding response dominant Clausocalanus...
To achieve their reproductive potential, barnacles combine tactile exploration of surface structural properties and integration cellular signals originating from antennular sensory setae within a developmentally defined, temporally narrow window settlement opportunity. Behavioural assays with cyprids coupled biometric analysis scanning electron microscopy-acquired images in the presence specific chemical compounds were used to investigate how on substratum is altered response these...
