Modelling seasonal dynamics of biomasses and nitrogen contents in a seagrass meadow (Zostera noltii Hornem.): application to the Thau lagoon (French Mediterranean coast)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Plus, Martin; Chapelle, Annie; Menesguen, Alain; Deslous-paoli, Jean-marc; Auby, Isabelle.
A numerical deterministic model for a seagrass ecosystem (Zostera noltii meadows) has been developed for the Thau lagoon. It involves both above- and belowground seagrass biomasses, nitrogen quotas and epiphytes. Driving variables are light intensity, wind speed, rain data and water temperature. This seagrass model has been coupled to another biological model in order to simulate the relative contributions of each primary producer to: (i) the total ecosystem production, (ii) the impact on inorganic nitrogen and (iii) the fluxes towards the detritus compartment. As a first step in the modelling of seagrass beds in the Thau lagoon, the model has a vertical structure based on four boxes (a water box on top of, three sediment boxes) and the horizontal...

Autores: Le Fur, Ines; De Wit, Rutger; Plus, Martin; Oheix, Jocelyne; Derolez, Valerie; Simier, Monique; Malet, Nathalie; Ouisse, Vincent.
Since the mid-20th century, Mediterranean lagoons have been affected by eutrophication, leading to significant changes in primary producers. In the early 2000s, management actions have been implemented to reduce nutrient inputs with the aim to achieve a good ecological status as requested by the EU water framework directive. As a result of these actions, a sharp decline in nutrient loads has been recorded in several lagoons leading to an oligotrophication of the water column. The analyses of a long-term data set (1998-2015) of 21 polyhaline and euhaline lagoons with contrasting trophic status allowed us to infer a general scheme for the changes in macrophyte assemblages during the oligotrophication process. Placing hypertrophic and oligotrophic conditions...

Resource Competition Affects Plankton Community Structure; Evidence from Trait-Based Modeling
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sourisseau, Marc; Le Guennec, Valerie; Le Gland, Guillaume; Plus, Martin; Chapelle, Annie.
Understanding the phenology of phytoplankton species is still a challenge and despite a lot of theoretical work on competition for ressources this process is under-represented in deterministic models. To study the main driver of the species selection, we thus used a trait-based model that keeps phenotypic variability through physiological trait parameterization. We next validate the results by using a key species, the toxic dinoflagellate Alexandrium minutum. Due to their monitoring, we show that harmful algae are ideal models for studying ecological niches and for contributing to this more global challenge. As a first step, a dimensionless model of an estuary (France) was built with water temperature and water exchanges deduced from a hydro-dynamic model....

Hydrodynamic characterization of the Arcachon Bay, using model-derived descriptors
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Plus, Martin; Dumas, Franck; Stanisiere, Jean-yves; Maurer, Daniele.
A numerical model (MARS-2D) was developed, with the aim of describing the hydrodynamics that prevail in Arcachon Bay. Direct model results as well as derived mixing and transport time-scales (tidal prism, local and integrated flushing times, age of water masses), were used to understand the behaviour of water masses and exchanges between the Bay and its frontiers. Particular attention was paid to the processes that drive the hydrodynamics (tides, wind and rivers), in order to understand their respective influence. The Arcachon Bay hydrodynamic system appears primarily to be highly influenced by tides; secondarily, by winds. About two third of the lagoon total volume is flushed in and out at each tidal cycle, which represent a mean tidal prism of 384...

Autores: Plus, Martin; Auby, Isabelle; Verlaque, Marc; Levavasseur, Guy.
The main photosynthesis and respiration parameters (dark respiration rate, light saturated production rate, saturation irradiance, photosynthetic efficiency) were measured on a total of 23 macrophytes of the Than lagoon (2 Phanerogams, 5 Chlorophyceae, 10 Rhodophyceae and 6 Phaeophyceae). Those measurements were performed in vitro under controlled conditions, close to the natural ones, and at several seasons. Concomitantly, measurements of pigment concentrations, carbon, phosphorous and nitrogen contents in tissues were performed. Seasonal intra-specific variability of photosynthetic parameters was found very high, enlightening an important acclimatation capacity. The highest photosynthetic capacities were found for Chlorophyceae (e.g. Monostroma obscurum...

Autores: Plus, Martin; Dalloyau, Sebastien; Trut, Gilles; Isabelle, Auby; De Montaudouin, Xavier; Emery, Eric; Claire, Noel; Christophe, Viala.
The spatial variability of seagrass meadows in Arcachon Bay, was studied between 1988 and 2008 using a combination of mapping techniques based on aerial photographs for intertidal dwarf-grass (Zostera noltti) beds and acoustic sonar for permanently submerged eelgrass (Zostera marina) populations. The results show a severe decline over the period for both species, as well as an acceleration of the decline since 2005 for Z. noltii. The total surface regression over the studied period is estimated to be 22.8 km(2) for Z. noltii and 2.7 km(2) for Z. marina, which represent declines of 33 and 74% respectively. Environmental data time series spanning the same period were investigated in order to seek the causes for such a decline. The calculated inter-annual...

Phytoplankton versus macrophyte contribution to primary production and biogeochemical cycles of a coastal mesotidal system. A modelling approach
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Plus, Martin; Auby, Isabelle; Maurer, Daniele; Trut, Gilles; Del Amo, Y.; Dumas, Franck; Thouvenin, Benedicte.
This study presents an assessment of the contributions of various primary producers to the global annual production and N/P cycles of a coastal system, namely the Arcachon Bay, by means of a numerical model. This 3D model fully couples hydrodynamic with ecological processes and simulates nitrogen, silicon and phosphorus cycles as well as phytoplankton, macroalgae and seagrasses. Total annual production rates for the different components were calculated for different years (2005, 2007 and 2009) during a time period of drastic reduction in seagrass beds since 2005. The total demand of nitrogen and phosphorus was also calculated and discussed with regards to the riverine inputs. Moreover, this study presents the first estimation of particulate organic carbon...

Environmental factors contributing to the development of brown muscle disease and perkinsosis in Manila clams (Ruditapes philippinarum) and trematodiasis in cockles (Cerastoderma edule) of Arcachon Bay
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Binias, Cindy; Do, Van Tu; Jude-lemeilleur, Florence; Plus, Martin; Froidefond, Jean-marie; De Montaudouin, Xavier.
The aim of the present study was to identify environmental factors that could explain the distribution of different pathologies of commercially exploited intertidal bivalves in an Atlantic lagoon, Arcachon Bay. In particular, the role of the salinity gradient as a driver was explored. The Manila clam Ruditapes philippinarum experienced two severe pathologies, perkinsosis, which is due to a protozoan parasite, and brown muscle disease (BMD), the etiological agent of which remains unknown. Perkinsus olseni infection was very low in a small low-salinity area but, at the scale of the entire lagoon, was more influenced by organic matter content in the sediment and by emersion time. BMD prevalence was also 2.6 times higher in the higher organic content area but...

An inventory of the marine macrophytes introduced into the Arcachon Basin has been carried out through an exhaustive bibliographical analysis complemented by several sampling campaign made in November 2005, July 2006, February and December 2007. As a result, 22 introduced species have been listed. Nine of them are new to the region, and Herposiphonia parca and Pterosiphonia tanakae, are recorded for the first time from the Atlantic Ocean. Of this exotic flora, 17 species have also been introduced into the Thau Lagoon (France, Mediterranean). Except for some old introductions for which the most probable vector is the shipping, an introduction along with shellfish transfers, directly from Japan or via other aquaculture sites is highly probable.

Autores: Plus, Martin; Deslous-paoli, Jean-marc; Auby, Isabelle; Dagault, Francoise.
The primary production and the respiration of Zostera noltii beds in the Thau lagoon were studied by means of the benthic bell jar technique, Concurrently, environmental data (temperature, light and nutrients) as well as morphological data of seagrass meadows (leaf width and height, density of shoots, above/below-ground biomass ratio) were collected with the purpose of explaining most of the observed variations in metabolism, Seagrass plus epiphyte respiration rates were influenced mainly by the water temperature, showing a typical exponential response to an increase in temperature, Surprisingly, measurements of production rates were not related to incoming light intensities recorded at the seagrass canopy level, An equation frequently used for terrestrial...

Under the WFD monitoring the “subtidal macroalgae” parameter is calculated for the second time on the Basque coast water body from the protocol used in Britain and adapted to local environmental context. In 2011, three stations were sampled instead of 5 in 2008. The result is the same to the one obtained in 2008 with a quality index "medium" for the whole of the water body. The main criterion penalizing the calculation of the index is "opportunistic species" for each station. There is variability between sites according to the criteria between the two campaigns reflecting the interest of monitoring every three years on the three sites.

Zostera noltii colonise en Méditerranée des baies abritées et des lagunes présentant des conditions abiotiques (e.g. atténuation lumineuse et salinité) très variées. Les zostères constituent des herbiers étendus et stables à Thau (Gerbal et Verlaque, 1995) qui est une lagune profonde et bien connectée à la mer (salinité peu variable). Dans le Vaccarès, moins bien connecté à la mer, cette espèce a présenté un développement important entre 1984 et 1996, alors que la salinité (moyenne annuelle) variait entre 30,1 et 4,8 (Grillas et Auby, 1996).

Introduction and objectives of the study: Understanding the operation modes of the coastline systems requires the study of the hydrodynamics responsible for transporting the whole of the chemical and biological elements of which they are composed. The idea of maintaining a close connexion between the physics, biology, geology and chemistry of the oceans is not new, and was for that matter the subject of a note in the first report of the International Council for the Study of the Oceans (ICSS) in 1902 (Sverdrup et al., 1954):  " it was seen from the beginning that the study of the physical conditions, of the chemical nature of the ocean waters, of the currents, etc., was of the greatest importance for the investigation of the problems connected with life,...

Modelling water discharges and nitrogen inputs into a Mediterranean lagoon - Impact on the primary production
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Plus, Martin; La Jeunesse, I; Bouraoui, F; Zaldivar, J; Chapelle, Annie; Lazure, Pascal.
The Soil and Water Assessment Tool (SWAT model, 2001 Version) has been applied to the Than lagoon catchment area in order to simulate water discharges and nutrient inputs into the lagoon over a 10 years period (1989-1999), and to provide routing inflows to a previously developed lagoon ecosystem model. The watershed model has been calibrated and validated using measured data available for the two main rivers. The results indicate that the mean annual nitrogen inputs into the Thau lagoon is 117 +/- 57 tons y(-1), with the two main rivers, contributing for 80% of total annual nitrogen export. The variations of outputs to the lagoon are nonetheless important from 1 year to another. Due to the local agricultural practices and a reduced in-stream natural...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ribaudo, Cristina; Plus, Martin; Ganthy, Florian; Auby, Isabelle.
The worldwide decline of seagrass meadows may result in the loss of relevant ecosystem services such as the carbon sequestration within marine ecosystems. In this paper, net primary production (NPP) of Zostera noltei meadows was assessed in the Arcachon Bay (SW France) with the aim of understanding the impact of meadows decline on C sequestration capacity at a basin scale. Net growth rates obtained by means of a year-long leaf-marking experiment (2005-2006) were coupled to interannual biomass measurements (1983-2010) to obtain a direct estimate of NPP. Concurrently, an indirect estimate was obtained through a mathematical model which embedded natural factors variation (temperature, light and nutrients). Z. noltei seasonal growth and leaf morphometry...

Introduction and objectives of the study: Understanding the operating modes of the coastline systems requires the study of the hydrodynamics responsible for transporting the whole of the geobiological compartments of which they are composed. The idea of maintaining a close connexion between the physics, biology, geology and chemistry of the oceans is not new, and was for that matter the subject of a note in the first report of the International Council for the Study of the Oceans (ICSS) in 1902 (Sverdrup et al., 1954): ... it was seen from the beginning that the study of the physical conditions, of the chemical nature of the ocean waters, of the currents, etc., was of the greatest importance for the investigation of the problems connected with life, that...

La forte augmentation des mortalités de juvéniles d’huître creuse depuis 2008 a relancé la problématique de l’approvisionnement en naissains de l’ostréiculture française. Dans ce contexte, cette étude a pour objectif d’étudier la faisabilité d’opérations de repeuplement en huîtres génétiquement plus résistantes, afin d’améliorer les performances de survie du naissain capté dans le milieu naturel. Cette étude s’est ainsi focalisée sur les deux bassins naisseurs historiques, Marennes-Oléron et Arcachon. Nous avons donc cherché à établir (1) une hiérarchie des bancs en fonction de l’expulsion de larves d’huître dans le bassin d’Arcachon, (2) une cartographie des liens en termes de connectivité entre les bancs des pertuis charentais et (3) la faisabilité du...

Typology of environmental conditions at the onset of winter phytoplankton blooms in a shallow macrotidal coastal ecosystem, Arcachon Bay (France)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gle, C; Del Amo, Y; Bec, B; Sautour, B; Froidefond, J; Gohin, Francis; Maurer, Daniele; Plus, Martin; Laborde, P; Chardy, P.
Phytoplankton dynamics were assessed in the macrotidal ecosystem of Arcachon Bay through high-frequency surveys over a 5-year period in order to characterize typology of environmental conditions at the onset of the productive period. Temporal variations of hydrological and biological parameters were examined in external and internal waters of the lagoon, during the winter-spring periods from 1999 to 2003. An additional survey was performed during winter-spring 2005 in order to study the vertical structure of the water column. The occurrence of winter phytoplankton blooms between January and March emerged as a recurrent event. The early onset of the productive period is influenced by the biological functioning of adjacent Bay of Biscay oceanic waters. It is...

De 2009 à 2011, le captage à Arcachon fut particulièrement mauvais. Des pontes tardives associées à de faibles quantités de larves “petites” indiquaient un problème probablement au niveau de la maturation ou de la ponte. Le programme FéLiBA consiste en un zoom, pour l’année 2013, sur la Fécondité des huîtres creuses en Lien avec la qualité de l’eau du Bassin d’Arcachon. Ce programme s’est traduit par différentes actions de terrain. Tout d’abord, la maturation des huîtres issues du captage d’Arcachon ou de Marennes-Oléron a été suivie à Arcachon (site du Tès) et comparée avec celle de la Rade de Brest (pointe du Château) au cours de l’année 2013. Puis, un bilan de la maturation des huîtres sauvages d’Arcachon a été établi fin juin 2013. La ponte a également...

Étude et modélisation des populations de macrophytes dans la lagune de Thau (Hérault, France)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Plus, Martin.
The works carried out can be divided in three main lines : design and management of experimental studies on primary production processes, macrophyte spatial distribution study and development of macrophyte and seagrass numerical models.  In situ and in vitro experiments have been performed with the aim of studying the processes and the parameters involved in the photosynthesis-respiration system, as well as to establish the main biotic (self-shading effect, physiology of the photosynthesis, carbon, nitrogen and chlorophyll tissu contents) and abiotic (temperature, light and nutrients) factors controlling macrobenthic primary production. A seagrass ecosystem model based on nitrogen and oxygen fluxes has been developped. Model calibration and validation have...

T.; Meisterhans, G.; Mesmer-dudons, N.; Caill-milly, Nathalie; Sanchez, Florence; Soudant, P.
Asari (= Manila) clam, Ruditapes philippinarum, is the second bivalve mollusc in terms of production in the world and, in many coastal areas, can beget important socio-economic issues. In Europe, this species was introduced after 1973. In Arcachon Bay, after a decade of aquaculture attempt, Asari clam rapidly constituted neo-naturalized population which is now fished. However, recent studies emphasized the decline of population and individual performances. In the framework of a national project (REPAMEP), some elements of fitness, stressors and responses in Arcachon bay were measured and compared to international data (41 publications, 9 countries). The condition index (CI=flesh weight/shell weight) was the lowest among all compared sites. Variation in...

While they had previously presented a hight stability, unlike in many coastal sites worldwide, eelgrass beds (Zostera noltii and Zostera marina) of Arcachon Bay have declined sharply since the 2000s. Various causes have been invoked to explain this phenomenon: climate anomalies, disease, over-grazing by herbivorous birds, contamination by herbicides, mechanical destruction during clam fishing. A multidisciplinary study was set up to study the possible effect of these factors, by putting into perspective the history of the seagrass beds and the temporal evolution of these parameters. After a chapter dealing with recent trends (2007-2010) of seagrasses in the Bay of Arcachon, the results relative to the various hypotheses are presented. These results allow...

Origin and composition of sediment organic matter in a coastal semi-enclosed ecosystem: An elemental and isotopic study at the ecosystem space scale
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Dubois, S.; Savoye, N.; Gremare, Antoine; Plus, Martin; Charlier, K.; Beltoise, A.; Blanchet, Hugues.
The origin and composition of sediment organic matter (SOM) were investigated together with its spatial distribution in the Arcachon Bay - a macrotidal lagoon that shelters the largest Zostera noltii meadow in Europe - using elemental and isotopic ratios. Subtidal and intertidal sediments and primary producers were both sampled in April 2009. Their elemental and isotopic compositions were assessed. Relative contributions of each source to SOM were estimated using a mixing model. The SOM composition tended to be homogeneous over the whole ecosystem and reflected the high diversity of primary producers in this system. On average, SOM was composed of 25% of decayed phanerogams, 19% of microphytobenthos, 20% of phytoplankton, 19% of river SPOM and 17% of...

Autores: Ratmaya, Widya; Soudant, Dominique; Salmon-monviola, Jordy; Plus, Martin; Cochennec-laureau, Nathalie; Goubert, Evelyne; Andrieux, Francoise; Barillé, Laurent; Souchu, Philippe.
The evolution of eutrophication (i.e., phytoplankton biomass) during recent decades was examined in the coastal waters of Vilaine Bay (VB, France) in relation to those in their main external nutrient sources, the Loire and Vilaine Rivers. Dynamic Linear Models, corroborated by the Mann-Kendall test, were used to study long-term trends and seasonality of dissolved inorganic nutrient and chlorophyll a concentrations (Chl a) in rivers and coastal waters between 1980 and 2013. The reduction in dissolved riverine inorganic phosphorus concentrations (DIP) from the early 1990s led to the decrease in their Chl a levels. However, dissolved inorganic nitrogen concentrations (DIN) decreased only slightly in the Vilaine and actually increased in the Loire, especially...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Fauvelle, Vincent; Belles, Angel; Budzinski, Helene; Mazzella, Nicolas; Plus, Martin.
The work presented here aims at comparing monitoring of S-metolachlor, the major pesticide in use in the Arcachon Bay (South West of France, transitional coastal area), by chemical analysis (monthly passive sampling) and contaminant dissipation modeling from sources (Mars-2D model). The global strategy consisted in i) identifying the major sources of S-metolachlor to the Bay, ii) monitoring these sources for 12 months, and iii) comparing modeled data in the Bay based on measured inputs, to chemical measurements made inside the Bay along with the 12-month source monitoring. Results first showed that the major S-metolachlor surface inputs to the Arcachon Bay are mainly from one single source. Modeled and measured data were in good agreement at 5 sites in the...

Suite à l’événement de grande ampleur d’efflorescence d’Alexandrium minutum et des toxicités associées en Rade de Brest en 2012, un projet a été élaboré avec la Région Bretagne dans le cadre du développement du port de Brest. L’Ifremer a organisé un échantillonnage dans l’estuaire de la rivière de Daoulas, zone la plus touchée en 2012, au cours des printemps-été 2013 et 2014. Un suivi de la présence d’A. minutum dans les sédiments a également été réalisé en hiver 2014. De ces suivis, des mesures réalisées au laboratoire à ce jour, des simulations du modèle Prévimer ainsi que des résultats du réseau Rephy et Velyger, il ressort que: * La rade de Brest peut aujourd’hui être considérée comme une zone à risque pour Alexandrium minutum. En effet, depuis 2012...

Autores: Plus, Martin; Chapelle, Annie; Lazure, Pascal; Auby, Isabelle; Levavasseur, G; Verlaque, M; Belsher, Thomas; Deslous-paoli, Jean-marc; Zaldivar, J; Murray, C.
A three-dimensional model coupling physical and biological processes for the whole Than lagoon (Mediterranean coast of France) was developed in order to assess the relationships between macrophytes and the oxygen and nitrogen cycles. Ten species have been inserted as forcing variables in the model. Plankton dynamics, shellfish cultivation impact and mineralization of organic matter are also considered, as well as nutrient and oxygen exchanges between the sediment and the water column.   Simulations with and without the macrophytes have shown that the system can be characterized as having a highly structured pattern involving lagoon nitrogen and oxygen cycles. This pattern is created by the combined influence of macrophytes, watershed and oyster farming....
