This study aims to describe the patterns of soft bottom macrozoobenthic richness along French coasts. It is based on a collaborative database developed by the “Réseau des Stations et Observatoires Marins” (RESOMAR). We investigated patterns of species richness in sublittoral soft bottom habitats (EUNIS level 3) at two different spatial scales: 1) seaboards: English Channel, Bay of Biscay and Mediterranean Sea and 2) 0.5° latitudinal and longitudinal grid. Total observed richness, rarefaction curves and three incidence-based richness estimators (Chao2, ICE and Jacknife1) were used to compare soft bottom habitats species richness in each seaboard. Overall, the Mediterranean Sea has the highest richness and despite higher sampling effort, the English Channel...

Typologie biosédimentaire de la baie de Saint-Brieuc (Manche ouest), et estimation de la biomasse des catégories trophiques macrozoobenthiques.
Provedor de dados: 5
Autores: Gros, Philippe; Hamon, Dominique.
The aim of this report is to provide biomass estimates (AFDW, g.m-2 ) of the four main components of the benthic food web in the southern part of the Bay of St-Brieuc: suspension-feeders, deposit-feeders, herbivores and carnivores. Patterns in the environmental data (i.e., sedimentary characters) are first analysed, and then related to the spatial distribution of communities ; both approaches use classical ordination techniques (PCA, correspondence analysis). A second typology, based on a review of published litterature concerning coastal macrozoobenthos feeding, ascribes each taxonomic unit to a trophic group. Finally, quantitative results are thus given per biota ; suspension-feeders appear to dominate (in terms of biomass) most of fine-sand habitats of...

Possible effects of global environmental changes on Antarctic benthos: a synthesis across five major taxa
Provedor de dados: 5
Autores: Ingels, Jeroen; Vanreusel, Ann; Brandt, Angelika; Catarino, Ana I.; David, Bruno; De Ridder, Chantal; Dubois, Philippe; Gooday, Andrew J.; Martin, Patrick; Pasotti, Francesca; Robert, Henri.
Because of the unique conditions that exist around the Antarctic continent, Southern Ocean (SO) ecosystems are very susceptible to the growing impact of global climate change and other anthropogenic influences. Consequently, there is an urgent need to understand how SO marine life will cope with expected future changes in the environment. Studies of Antarctic organisms have shown that individual species and higher taxa display different degrees of sensitivity to environmental shifts, making it difficult to predict overall community or ecosystem responses. This emphasizes the need for an improved understanding of the Antarctic benthic ecosystem response to global climate change using a multitaxon approach with consideration of different levels of biological...

Atlas thématique de l'environnement marin en baie de Saint-Brieuc (Côtes-d'Armor)
Provedor de dados: 5
Autores: Augris, Claude; Hamon, Dominique.
This atlas presents in a synthetic form the hydrodynamical, geological and biological characteristics of one of the most studied region of the French littoral. Geologic and geophysical data of the Saint-Brieuc Bay show that the deep basement consists of pre-palaeozoic or palaeozoic sedimentary series in the centre of the Bay, whereas metamorphic and magmatic formations are dominant in coastal regions. The location of superficial sediments in the Bay, is mainly due to marine currents. A granulometric gradient, from very fine to coarse sediments, appears in two directions: from the coast towards the high sea, and from the west to the east. Rocky substrates disrupt the sediment distribution, with, most of the time, a concentration of coarse sediments near the...

Long-term changes and coastal eutrophication. Examples from the Aland Islands and the Archipelago Sea, northern Baltic Sea
Provedor de dados: 5
Autores: Bonsdorff, E; Blomqvist, Em; Mattila, J; Norkko, A.
The coastal and archipelago waters of the northern Baltic Sea are influenced by increasing eutrophication (significantly increasing temporal trends in nutrient availability). Increased nutrient levels and pelagic primary production have led to decreased transparency in the water body, increased plankton biomass, and increased amounts of filamentous algae. Large-scale and long-term (15-30 years) comparisons have shown that zoobenthic communities have changed significantly (altered species diversity, increased total abundance and increased biomass). The stress in the ecosystem is also illustrated at the population level (Macoma balthica). An increasing trend is shown for a near-shore fish community, where the increase in biomass has been linear over the past...

Autores: Guidi, L.
The present study deals with technical problems encountered under lab conditions in studies of trophic relations between deposit-feeding invertebrates and microorganisms. Using 2 pure cultures of Pseudomonas and Navicula , it was shown that these microorganisms will attach to artificial (glass beads) and natural (sand grains) substrates. Best microbial attachment was observed on sand (up to 4.8 x 10 super(8) cells.g super(-1) dry wt.). The radioactive labelling of the microorganisms depends not only on the form under which the isotope ( super(14)C) is supplied to the cultures, but also on the time and the duration of the labelling. 70% of the isotope was incorporated in a stable manner by the diatoms. The bacteria incorporated, at most, 34% of the...

Annual and seasonal dynamics of deep-sea megafaunal epibenthic communities in Barkley Canyon (British Columbia, Canada): a response to climatology, surface productivity and benthic boundary layer variation
Provedor de dados: 5
Autores: Chauvet, Pauline; Metaxas, Anna; Hay, Alex E.; Matabos, Marjolaine.
Understanding the impact of the environment on temporal trends in the composition and abundance of deep-sea species is essential for forecasting evolution of the community in the context of climate change. The recent development of deep-sea observatories enables multidisciplinary studies of long duration and high temporal resolution. We used a platform at the Ocean Networks Canada NEPTUNE Observatory located in the axis of Barkley Canyon between June 2012 and January 2015 to: (1) characterize the megabenthic community and the environmental conditions in the canyon; (2) investigate temporal patterns in the faunal community; and (3) determine the influence of environmental conditions on the observed patterns. The megafaunal epibenthic community, which...

Influence of stability and fragmentation of a worm-reef on benthic macrofauna
Provedor de dados: 5
Autores: Godet, Laurent; Fournier, Jerome; Jaffre, Mikael; Desroy, Nicolas.
In coastal areas, reef-builder worms often are bio-engineers by structuring their physical and biological environment. Many studies showed that this engineering role is determined by the densities of the engineer species itself, the highest densities approximately corresponding to the most stable areas from a sedimentological point of view, and hosting the richest and the most diverse benthic fauna. Here, we tested the potential influence of the spatio-temporal dynamics and the spatial fragmentation of one of the largest European intertidal reefs generated by the marine worm Lanice conchilega (Pallas, 1766) (Annelida, Polychaeta) on the associated benthic macrofauna. We demonstrated that the worm densities do have a significant positive role on the...

Autores: Bremec, C.; Lasta, M.L.
The faunistic characteristics in feeding grounds of Micropogonias furnieri, considering many relationships with the diet of the species in the Argentine-Uruguayan Common Fishing Zone, are studied. Benthos was collected in 33 sampling stations during the reseach cruise H-13/94, between 9-44 meters depth in the area El Rincón (Buenos Aires Prov., Argentina), with hard bottom and Picard dredges. Cluster analysis (Q mode, Sorensen index) was applied to these data and to the invertebrate by-catch obtained in 58 demersal hauls. Frequency size distribution of mussels in its distribution area is also presented. Stomach contents of 177 specimens of white croaker were studied from the percentage of ocurrence frequence of every alimentary item. Present results and...

Initial results of the benthic fauna studies in the northern Lake Victoria
Provedor de dados: 20
Autores: Mbahinzireki, G.B.
The paper presents initial results of relative abundance, composition     and distribution of benthic organisms in an ecologically and     environmentally changing northern Lake Victoria. The results suggest     that the density of most of the zoobenthos has gone up since the     pre-perch era despite the absence of comparative data. Increases in     densities were noted for dipteran larvae followed by Caridina     nilotica, ostracods, oligochaetes, molluscs and nymphs of Anisoptera     and Ephemeroptera, in that order. Possible reasons to account for the     increase are advanced. Inshore stations held higher densities than the     offshore station. Type of the sediment and physico-chemical factors     seem to influence the production and distribution of...

Asociación bentónicas en bancos de vieira patagónica (Zygochlamys patagonica) en el Mar Argentino
Provedor de dados: 20
Autores: Schejter, L.
The different aspects of the benthic assemblages at the Patagonian scallop beds in the Argentine Sea (SW Atlantic) were studied. The Patagonian scallop (Zygochlamys patagonica) is a commercial species distributed in the Magellanic Biogeographic Province, and has been commercially exploited since 1996. Temporal and spatial studies were performed in the community composition between 39°50'S and 36°15'S, and between 1998 and 2003, concluding that the species association was persistent after more than 7 years of trawling activities. Species composition in an exclusion area (closed to scallop fishing) did not differ from surrounding fished areas during the studied period, showing only a higher scallop biomass. ABC curves showed a pattern coincident with a non...

Meiobenthos of the central Arctic Ocean with special emphasis on the nematode community structure
Provedor de dados: 27
Autores: Vanreusel, A.; Clough, L.M.; Jacobsen, K.; Ambrose, W.; Jivaluk, J.; Ryheul, V.; Herman, R.; Vincx, M.
We investigated the abundance of the meiobenthos and the biomass and community structure of the nematodes in the central Arctic Ocean along two separate transects during 1991 and 1994. Meiobenthos abundances ranged from &lt; 100 to 600 individuals per 10 cm², in the same order of magnitude as in other oligotrophic areas of the world's deep ocean. Nematodes were the numerically dominant meiofaunal group at every station. Nematode biomass ranged from &lt; 1 to 48 µg dry weight per 10 cm². A combination of water depth and latitude explained 55% of the variability among stations in nematode biomass and 67% of the variability of total abundance, implying that both vertical and advective fluxes are important sources of food to the meiofaunal communities. The...

Early postlarval fish in the hyperbenthos of the Dutch Delta (south-west Netherlands)
Provedor de dados: 27
Autores: Beyst, B.; Mees, J.; Cattrijsse, A.
Early (post)larval fish constitute a significant part of the temporary hyperbenthos, i.e. of the fauna living in the lower reaches of the water column close to the substratum. Information on the densities and spatial and temporal variations of these stages, as well as on their lengths at the moment of occurrence, can be an important contribution to the knowledge of their dispersion, migrations and to the identification of possible bottlenecks in their recruitment. Therefore the hyperbenthos of the Voordelta, a shallow coastal zone in front of the Dutch Delta, as well as that of the subtidal channels and the intertidal brackish marsh creeks of the Westerschelde Estuary, was sampled monthly during one year by means of a sledge and a stow net. A total of 37...
