Analyse du benthos au large du site des Caps. Recherche de l'impact d'une extraction de granulats
Provedor de dados: 5
Autores: Davoult, Dominique; Richard, Alain.
Le site des Caps est une zone littorale bien particulière, bordure française du goulet du Pas-de-Calais, à la fois rétrécissement géographique important entre la France et l'Angleterre, et limite entre la Manche Orientale et le sud de la Mer du Nord. Une zone d'extraction de granulats marins a été exploitée entre 1971 et 1980 au large de ce site. Cette exploitation a été arrêtée en 1982 par arrêté préfectoral pour des raisons d'atteinte à l'environnement et d'entrave à la pêche. La présente étude a pour but de décrire les peuplements au large du site des Caps, englobant le quadrilatère d'exploitation, de faire ressortir leurs caractéristiques. et d'essayer d'apprécier l'impact dû à l'extraction. Deux problèmes majeurs sont soulevés : d'une part, aucune...

Accumulation of detached kelp biomass in a subtidal temperate coastal ecosystem induces succession of epiphytic and sediment bacterial communities.
Provedor de dados: 5
Autores: Brunet, Maéva; De Bettignies, Florian; Le Duff, Nolwen; Tanguy, Gwenn; Davoult, Dominique; Leblanc, Catherine; Gobet, Angelique; Thomas, François.
Kelps are dominant primary producers in temperate coastal ecosystems. Large amounts of kelp biomass can be exported to the seafloor during the algal growth cycle or following storms, creating new ecological niches for the associated microbiota. Here, we investigated the bacterial community associated with the kelp Laminaria hyperborea during its accumulation and degradation on the seafloor. Kelp tissue, seawater and sediment were sampled during a six‐month in situ experiment simulating kelp detritus accumulation. Evaluation of the epiphytic bacterial community abundance, structure, taxonomic composition and predicted functional profiles evidenced a biphasic succession. Initially dominant genera (Hellea, Litorimonas, Granulosicoccus) showed a rapid and...

Community, Trophic Structure and Functioning in two contrasting Laminaria hyperborea forests
Provedor de dados: 5
Autores: Leclerc, Jean-charles; Riera, Pascal; Laurans, Martial; Leroux, Cedric; Leveque, Laurent; Davoult, Dominique.
Worldwide kelp forests have been the focus of several studies concerning ecosystems dysfunction in the past decades. Multifactorial kelp threats have been described and include deforestation due to human impact, cascading effects and climate change. Here, we compared community and trophic structure in two contrasting kelp forests off the coasts of Brittany. One has been harvested five years before sampling and shelters abundant omnivorous predators, almost absent from the other, which has been treated as preserved from kelp harvest. δ15N analyses conducted on the overall communities were linked to the tropho-functional structure of different strata featuring these forests (stipe and holdfast of canopy kelp and rock). Our results yielded site-to-site...

Benthic metabolism over the emersion - Immersion alternation in sands colonized by the invasive Manila clam Ruditapes philippinarum
Provedor de dados: 5
Autores: Migne, Aline; Trigui, Rima Jihane; Davoult, Dominique; Desroy, Nicolas.
The effect of an invasive infaunal suspension-feeding bivalve, the Manila clam Ruditapes philippinarum, on benthic inorganic carbon and nutrient fluxes was examined through in situ incubations. Measurements were performed in spring and summer on a tidal sandflat of the Rance estuary (south part of the Western English Channel) colonized by the Manila clam after its deliberate introduction in the 1990's. Benthic inorganic carbon fluxes were measured using light and dark benthic chambers both at emersion and immersion. Benthic nutrient fluxes were measured using dark benthic chambers at immersion. Inorganic carbon (IC) and ammonium sediment release under darkness at immersion reached 5.60 mmol m−2 h−1 and 441 μmol m−2 h−1 respectively for a clam density of...

Calcium carbonate production of a dense population of the brittle star Ophiothrix fragilis (Echinodermata : Ophiuroidea): role in the carbon cycle of a temperate coastal ecosystem
Provedor de dados: 5
Autores: Migne, A; Davoult, Dominique; Gattuso, Jp.
The production of calcium carbonate by a dense Ophiothrix fragilis population was calculated in order to investigate its role in the carbon budget of a temperate coastal ecosystem (Dover Strait, eastern English Channel). Production, calculated using monthly data of population density, demographic structure and a size/CaCO3 conversion, was 682 g CaCO3 m(-2) yr(-1). Assuming that the molar ratio of CO2 released to CaCO3 precipitated varied with temperature between 0.66 and 0.73, this production would result in the release of 4.8 mol CO2 m(-2) yr(-1). This calculation reinforces the suggestion that this coastal system is a source of CO2 to the atmosphere.

Impact of the Phaeocystis globosa spring bloom on the intertidal benthic compartment in the eastern English Channel: A synthesis
Provedor de dados: 5

From 1999 to 2005, studies carried out in the frame of regional and national French programs aimed to determine whether the Phaeocystis globosa bloom affected the intertidal benthic communities of the French coast of the eastern English Channel in terms of composition and/or functioning. Study sites were chosen to cover most of the typical shore types encountered on this coast (a rocky shore, an exposed sandy beach and a small estuary). Both the presence of active Phaeocystis cells and their degradation product (foam) did have a significant impact on the studied shores. The primary production and growth rates of the kelp Saccharina latissima decreased during the bloom because of a shortage of fight and nutrient for the macroalgae. On sandy sediments, the...

Spatial and temporal variability of CO2 fluxes at the sediment-air interface in a tidal flat of a temperate lagoon (arcachon bay, France)
Provedor de dados: 5
Autores: Migne, Aline; Davoult, Dominique; Spilmont, Nicolas; Ouisse, Vincent; Boucher, Guy.
This study aimed to explore the spatial and temporal variability of benthic metabolism in a temperate mesotidal lagoon. This was achieved by measuring fluxes of CO2 in static chambers during emersion, both under light and dark conditions. Three sample sites were selected according to their tidal level (upper or mid), their sediment type (sand or mud) and the presence/absence of the seagrass Zostera noltei. The three sites were investigated at three seasons (end of winter, spring and beginning of autumn). At each site and each season, three benthic chambers were used simultaneously in successive incubations over the emersion period. The sediment chlorophyll-a content varied seasonally in the upper sands (reaching 283 mg.m− 2 in spring) but not in the mid...

Combined effects of global climate change and nutrient enrichment on the physiology of three temperate maerl species
Provedor de dados: 5
Autores: Qui-minet, Zujaila Nohemy; Coudret, Jérôme; Davoult, Dominique; Grall, Jacques; Mendez‐sandin, Miguel; Cariou, Thierry; Martin, Sophie.
Made up of calcareous coralline algae, maerl beds play a major role as ecosystem engineers in coastal areas throughout the world. They undergo strong anthropogenic pressures, which may threaten their survival. The aim of this study was to gain insight into the future of maerl beds in the context of global and local changes. We examined the effects of rising temperatures (+3°C) and ocean acidification (−0.3 pH units) according to temperature and pH projections (i.e., the RCP 8.5 scenario), and nutrient (N and P) availability on three temperate maerl species (Lithothamnion corallioides, Phymatolithon calcareum, and Lithophyllum incrustans) in the laboratory in winter and summer conditions. Physiological rates of primary production, respiration, and...
