Oil spills threaten coastlines where biological processes supply essential ecosystem services. Therefore, it is crucial to understand how oil influences the microbial communities in sediments that play key roles functioning. Ecosystems such as are characterized by intensive bioturbation due burrowing macrofauna may modify metabolisms. It thus consider when determining impact of on communities. In this study, an experimental laboratory device maintaining pristine collected mudflat microcosms...
Aims: To isolate and identify alkane-degrading bacteria from deep-sea superficial sediments sampled at a north-western Mediterranean station. Methods Results: Sediments the water/sediment interface 2400 m depth were with multicorer ANTARES site off French coast promptly enriched Maya crude oil as sole source of carbon energy. Alkane-degrading belonging to genera Alcanivorax, Pseudomonas, Marinobacter, Rhodococcus Clavibacter-like isolated, indicating that same groups potentially involved in...
Abstract Empirical evidence of the effective degradation at environmentally relevant conditions organophosphate esters (OPEs) flame retardants and plasticizers in coastal sediments from an impacted area NW Mediterranean Sea is provided. Half-lives varied 23.3 to 77.0 (abiotic conditions) 16.8 46.8 days (biotic conditions), depending on compound, highlighting role microbial assemblages enhancing OPE degradation. After immediate significant reduction bacterial abundance due addition sediment...
Particle mixing and irrigation of the seabed by benthic fauna (bioturbation) have major impacts on ecosystem functions such as remineralization organic matter sediment-water exchange. As a tribute to Prof. Gaston Desrosiers Nereis Park association, eighteen laboratories carried out collaborative experiment acquire global snapshot particle reworking polychaete Hediste diversicolor at 16 sites surrounding Northern Atlantic. Organisms soft sediments were collected during May – July different...
Bioindicators assess the mangroves ecological state according to types of pressures but they differ with ecosystem’s specificities. We investigated benthic meiofauna diversity and structure within low human-impacted in French Guiana (South America) response sediment variables various distances main city. Contaminant’s concentrations differed among stations, remained below toxicity guidelines. Meiofauna (Foraminifera, Kinorhyncha, Nematoda) however varied accordingly. Nematode’s...
Gorgonians are iconic species of Mediterranean benthic communities. They ecosystem engineers and their conservation is essential for the biodiversity marine Yet these long-lived particularly vulnerable to natural or anthropogenic disturbances. The objective this study define demographic characteristics health status gorgonian forests two gorgonians Paramuricea clavata (Risso, 1826) Eunicella cavolini (Koch, 1887) over fifteen years. potential impact changing environmental conditions assessed...
Mangroves develop under environmental conditions and anthropogenic pressures whose impact on benthic meiofauna remains poorly understood. It is unclear how communities are structured according to local sedimentary conditions. This study was designed characterize the community structure of nematodes (dominant taxa) associated forcings in intertidal mangrove sediments from Mayotte (Indo-West-Pacific), Martinique Guadeloupe (Caribbean). Sediment cores were sampled at end dry season low tide...
