Temporal variability of benthic macrofauna on Cassino beach, southernmost Brazil
Provedor de dados: 76
Autores: Neves,Luciano P. das; Silva,Pedro de S. R. da; Bemvenuti,Carlos E.
The temporal variability of benthic macrofauna on Cassino beach, southernmost Brazil, was studied for a period of one year (June 2004 to May 2005) based on monthly sampling. Three sites were selected distant 50m from each other. At each site, 3 transects were established, 2m equidistant from one another. Each transect extended from the base of the primary dunes to the inner surf zone at approximately 1m in depth, with 7 or 8 sampling levels. Within transects, the distance between the levels was 20m until the upper swash zone, from which distance was 10m until the 1-meter isobath. The temporal variation in the abundance of benthic macrofauna observed in the present study can be attributed to (1) the positive effects of the recruitment peaks and migration of...

Relationships between benthic macrofauna and habitat suitability for juvenile common sole (Solea solea, L.) in the Vilaine estuary (Bay of Biscay, France) nursery ground
Provedor de dados: 5
Autores: Nicolas, Delphine; Le Loch, Francois; Desaunay, Yves; Hamon, Dominique; Blanchet, Aline; Le Pape, Olivier.
Coastal and estuarine systems are among the most threatened by human activities which damage their ecological function and, in particular, their nursery role for many marine species. In this context, the protection of these vital ecosystems is a critical issue for the management of fisheries resources. To that aim, functional approaches have to be developed that make it possible to assess habitat suitability and quality. The common sole, Solea solea (L.) was selected as an indicator species to identify the features of coastal and estuarine nursery habitats in the Bay of Biscay (France).   Previous studies have shown that young-of-the-year (YOY) sole are strongly dependent upon various abiotic factors, and especially bathymetry, sediment cover and the...

Effet d’une espèce ingénieur sur la diversité et le fonctionnement des communautés benthiques : l’habitat récifal à Sabellaria alveolata
Provedor de dados: 5
Autores: Jones, Auriane.
Coastal zones worldwide are home to a large diversity of ecosystem engineers that perform key functions such as the recycling of organic matter and nutrients. The habitats resulting from the biological activity of these species are exposed to numerous disturbances such as over harvesting and trampling or via coastal modification. In this context, it is becoming key to understand the functioning of these engineered habitats and how they are affected by increasing disturbances. During my PhD, I used the reef habitat built by the gregarious tubiculous polychaete Sabellaria alveolata as a study case. First, the environmental and biotic changes associated with the establishment of a S. alveolata reef and its increasing disturbance were assessed, focusing on...

Réseau de surveillance benthique (REBENT) – Région Bretagne. Approche sectorielle subtidale : Identification et caractérisation des habitats benthiques du secteur Morlaix
Provedor de dados: 5
Autores: Ehrhold, Axel; Hamon, Dominique; Chevalier, Claire.
In 2000, Ifremer launched and coordinated the development of a monitoring strategy for the REBENT network (REseau BENThique) in order to assess the aftermath of the “Erika” oil spill which took place in December 1999. Its aim is to provide consistent baseline knowledge on coastal benthic habitats, as well as to develop a monitoring tool that detects changes at various spatial and temporal scales. Sector-based seabed habitat mapping in shallow water (&lt; 50 m deep), is currently being conducted throughout Brittany's coastal waters using a combination of geoacoustic marine systems together with ground-truthing using biological grab sampling and seabed observations. Due to the overlap of soft and rocky bottoms, and contrasting hydrological conditions, the...

Effets du changement climatique sur la distribution de la macrofaune benthique en Manche
Provedor de dados: 5
Autores: Gaudin, François.
In the North-East Atlantic, the English Channel constitutes a biogeographical transition zone between the Boreal and Lusitanian provinces. Thus, many species reach there their distribution range limits. The aim of this thesis is to assess the effects of recent climate change on the distribution of the subtidal benthic macrofauna, poorly studied to date, basing on the comparison of data collected during a cool period (i.e. 1960s-70s) and during a warm period (i.e. 2012 and 2014) in the circalittoral coarse sediments. Two large communities were highlighted in the study of the structure of the assemblages found in this habitat: the gravelly coarse sand community and the pebbles and gravels community. The analysis of the evolution of seabed temperature for the...

Consommation de la macro-faune invertébrée  benthique par les oiseaux d'eau en baie du Mont-Saint-Michel
Provedor de dados: 5
Autores: Le Mao, Patrick; Pasco, Pierre-yves; Provost, Sébastien.
An evaluation of the energy transfer between zoobenthos and water birds in the Mont-Saint-Michel bay was carried out from October 2003 until September 2004. Global consumption by waders is similar to that estimated on data collected 20 years ago, in spite of strong variations in seasonal occurrence and species composition of shorebirds populations in the bay. Total consumption (including gulls and predatory anseriformes) is about 2,15 g ash free dry weight/m2 /year, a very low figured if compared to results from the Wadden Sea. These two results seems to confirm the initial findings from the PNEC research program in the Mont-Saint-Michel bay: the bay is an oligotrophic system (oceanic type) presenting a strong functional inertness in the mid and long term,...

Influence of oyster culture practices and environmental conditions on the ecological status of intertidal mudflats in the Pertuis Charentais (SW France): A multi-index approach
Provedor de dados: 5
Autores: Bouchet, Vincent; Sauriau, Pierre-guy.
The ecological quality status (EcoQ) of intertidal mudflats constrained by Pacific oyster farming was assessed by single (H', AMBI, BENTIX and BOPA) and multimetric (M-AMBI and average score) index approaches in the Pertuis Charentais (SW France). Fifteen sampling stations were monitored seasonally for sedimentological features and macrozoobenthos in 2004. Sediments affected by oyster biodeposits showed organic matter enrichment, and sediments from off-bottom culture sites had higher organic matter contents and lower redox potentials than sediments from on-bottom culture sites. Biotic indices consistently registered responses of macrozoobenthos to organic enrichment but there was only partial agreement between single index-derived EcoQs. The average score...

Models of general community assembly mechanisms simulating the spatial and temporal dynamics of benthic biodiversity
Provedor de dados: 5
Autores: Alexandridis, Nikolaos.
Benthic macroinvertebrates are part of a complex network of interactions. The spatial and temporal scales of the processes that form the basis for these interactions have traditionally restricted their empirical investigation. The first chapter of the manuscript attempts a review of the modelling tools that have been employed for the study of the marine benthos. The implementation of a mechanistic modelling framework seems fitting, but it requires the derivation of a few model entities with a clear functional role. The second chapter of the manuscript employs the emergent group hypothesis to do that in a way that is objective and testable. The resulting grouping is tested against theoretical expectations and the results support its ability to represent...

Dynamique et réponse fonctionnelle des foraminifères et de la macrofaune benthiques en zone ostréicole dans les pertuis charentais
Provedor de dados: 5
Autores: Bouchet, Vincent.
In oyster farming areas, organic matter fluxes toward sediment is increased. Pacific oysters (Crassostrea gigas) reject organic-rich faeces and pseudofaeces as a result of filtration process. Organic matter can be consumed by benthic fauna, but in excess it can entails the reduction of benthic faunal species richness, abundance and biomass. Organic matter degradation also induces hypoxic (or anoxic) conditions in the sediment, and production of ammonia and sulfides in toxic concentrations. The main objective of this study is to assess the effects of oyster farming on benthic intertidal ecosystems in the Pertuis Charentais. Benthic macrofauna, living (stained) foraminifera, and physicochemical characteristics of the water column and sediment were used as...
