Chemosynthetic symbioses are partnerships between invertebrate animals and chemosynthetic bacteria. The latter the primary producers, providing most of organic carbon needed for animal host's nutrition. We sequenced genomes symbionts from lucinid bivalve Loripes lucinalis stilbonematid nematode Laxus oneistus. both host species encoded nitrogen fixation genes. This is remarkable as no marine symbiont was previously known to be capable fixation. detected nitrogenase expression by clams at...
We investigated the mechanisms leading to rapid death of corals when exposed runoff and resuspended sediments, postulating that killing was microbially mediated. Microsensor measurements were conducted in mesocosm experiments naturally accumulated sediment on corals. In organic-rich, but not organic-poor sediment, pH oxygen started decrease as soon coral. Organic-rich sediments caused tissue degradation within 1 d, whereas had no effect after 6 d. harmful organic-rich hydrogen sulfide...
The production of biodegradable plastic is increasing. Given the augmented littering these products an increasing input into sea expected. Previous laboratory experiments have shown that degradation starts within days to weeks. Little known about early composition and activity biofilms found on conventional debris its correlation in marine environment. In this study we investigated formation shopper bags consequences for plastic. Samples polyethylene were tested Mediterranean Sea 15 33 days....
Marine coastlines colonized by seagrasses are a net source of methane to the atmosphere. However, emissions from these environments still poorly constrained, and underlying processes responsible microorganisms remain largely unknown. Here, we investigated turnover in seagrass meadows

Plastic particles in the ocean are typically covered with microbial biofilms, but it remains unclear whether distinct communities colonize different polymer types. In this study, we analyzed forming biofilms on floating microplastics a bay of island Elba Mediterranean Sea. Raman spectroscopy revealed that plastic mainly comprised polyethylene (PE), polypropylene (PP), and polystyrene (PS) which were brittle featured cracks. Fluorescence situ hybridization imaging by high-resolution...
Abstract Symbiotic N 2 -fixing microorganisms have a crucial role in the assimilation of nitrogen by eukaryotes nitrogen-limited environments 1–3 . Particularly among land plants, symbionts occur variety distantly related plant lineages and often involve an intimate association between host symbiont 2,4 Descriptions such symbioses are lacking for seagrasses, which evolved around 100 million years ago from terrestrial flowering plants that migrated back to sea 5 Here we describe symbiont, ‘...
The performance of the biodegradable plastic materials polyhydroxybutyrate (PHB), polybutylene sebacate (PBSe) and co-terephthalate (PBSeT), polyethylene (LDPE) was assessed under marine environmental conditions in a three-tier approach. Biodegradation lab tests (20°C) were complemented by mesocosm with natural sand seawater field warm-temperate Mediterranean Sea (12–30°C) tropical Southeast Asia (29°C) three typical coastal scenarios. Plastic film samples exposed eulittoral beach, pelagic...
Plastic pollution of the ocean is a top environmental concern. Biodegradable plastics present potential "solution" in combating accumulation plastic pollution, and their production currently increasing. While these polymers will contribute to future marine debris budget, very little known still about behavior biodegradable different natural environments. In this study, we molecularly profiled entire microbial communities on laboratory confirmed polybutylene sebacate-co-terephthalate (PBSeT)...
Exposure of coral reefs to river plumes carrying increasing loads nutrients and sediments is a pressing issue for around the world including Great Barrier Reef (GBR). Laboratory experiments were conducted investigate effects changes in inorganic (nitrate, ammonium phosphate), salinity various types suspended isolation combination on rates fertilisation early embryonic development scleractinian Acropora millepora. Dose–response showed that declined significantly with decreasing salinity,...
Background Coral reefs degrade globally at an alarming rate, with benthic algae often replacing corals. However, the extent to which contribute coral mortality, and potential mechanisms involved, remain disputed. Recent laboratory studies suggested that kill corals by inducing hypoxia on surface, through stimulated microbial respiration. Methods/Findings We examined main premise of this hypothesis measuring in situ oxygen microenvironments contact interface between massive Porites spp. turf...
Benthic cyanobacterial mats (BCMs) are impacting coral reefs worldwide. However, the factors and mechanisms driving their proliferation unclear. We conducted a multi-year survey around Caribbean island of Curaçao, which revealed highest BCM abundance on sheltered close to urbanised areas. Reefs with high were also characterised by benthic cover macroalgae low corals. Nutrient concentrations in water-column consistently low, but markedly increased just above substrata (both sandy hard)...
The increasing amount of plastic littered into the sea may provide a new substratum for benthic organisms. These marine fouling communities on have not received much scientific attention. We present, to our knowledge, first comprehensive analysis their macroscopic community composition, primary production and polymer degradation comparing conventional polyethylene (PE) biodegradable starch-based blend in coastal pelagic habitats Mediterranean Sea. biomass layer increased significantly over...
The pollution of the natural environment, especially world’s oceans, with conventional plastic is major concern. Biodegradable plastics are an emerging market bringing along potential chances and risks. fate these materials in environment their possible effects on organisms ecosystems has rarely been studied systematically not well understood. For marine reliable field test methods standards for assessing certifying biodegradation to bridge laboratory respirometric data lacking. In this work...
We report primary production and respiration of Posidonia oceanica meadows determined with the non-invasive aquatic eddy covariance technique. Oxygen fluxes were measured in late spring at an open-water meadow (300 m from shore), a nearshore (60 adjacent sand bed. Despite oligotrophic environment, highly productive autotrophic. Net ecosystem (54 to 119 mmol m-2 d-1) was about one-half gross production. In sands, net tenth- twentieth smaller (4.6 d-1). Thus, P. are oasis productivity...
Ongoing efforts focus on quantifying plastic pollution and describing estimating the related magnitude of exposure impacts human environmental health. Data gathered during such work usually follows a receptor perspective. However, Life Cycle Assessment (LCA) represents an emitter This study examines existing data gathering reporting approaches for field laboratory studies micro- nanoplastics (MNPs) effects relevant to LCA inputs. The outcomes indicate that perspective do not typically...
Microsensors are powerful tools for microenvironment studies, however their use has often been restricted to laboratory applications due the lack of adequate equipment in situ deployments. Here we report on new features, construction details, and examples an improved diver-operated motorized microsensor profiler underwater field operation a water depth 25 m. The final precision 5 μm, can accommodate amperometric Clark-type microsensors oxygen hydrogen sulfide, potentiometric micro- sensors...
The anaerobic oxidation of methane (AOM) is a key biogeochemical process regulating emission from marine sediments into the hydrosphere. AOM largely mediated by consortia methanotrophic archaea (ANME) and sulfate-reducing bacteria (SRB), has mainly been investigated in deep-sea sediments. Here we studied seepage at four spots located 12 m water depth coastal, organic carbon depleted permeable sands off Island Elba (Italy). We combined measurements, sequencing-based community analyses situ...
