Résumé :
In this study, we evaluated the quality of marine environment in central Vietnam after the disaster caused by Formosa Ha Tinh Steel Corporation (Formosa), using both bio-indicators (benthos) and chemical indicators. Results show that using benthic fauna, especially meio-benthos can obtain data on the quality of marine environment faster and more accurate than using chemical indicators. In marine environment, monitoring contaminated areas and contamination sources is difficult since currents are normally strong, contaminants often move fast and far away from the sources. For the reasons, using benthos as indicator to localize the contaminated areas as well as assess the quality of marine environment can be an effective method. However, this indicator cannot help to identify the exact contaminants and using this requires a comprehensive knowledge on sea bottom topography, sedimentary characteristics, sea currents, biological competition, etc.

Résumé :
ABSTRACT Elucidating the relationship between ciliate communities in the benthos and the plankton is critical to understanding ciliate diversity in marine systems. Although data for many lineages are sparse, at least some members of the dominant marine ciliate clades Oligotrichia and Choreotrichia can be found in both plankton and benthos, in the latter either as cysts or active forms. In this study, we developed a molecular approach to address the relationship between the diversity of ciliates in the plankton and those of the underlying benthos in the same locations. Samples from plankton and sediments were compared across three sites along the New England coast, and additional subsamples were analyzed to assess reproducibility of methods. We found that sediment and plankton subsamples differed in their robustness to repeated subsampling. Sediment subsamples (i.e., 1-g aliquots from a single ∼20-g sample) gave variable estimates of diversity, while plankton subsamples produced consistent results. These results indicate the need for additional study to determine the spatial scale over which diversity varies in marine sediments. Clustering of phylogenetic types indicates that benthic assemblages of oligotrichs and choreotrichs appear to be more like those from spatially remote benthic communities than the ciliate communities sampled in the water above them.

Résumé :
Abstract One of the ecological roles of seagrass ecosystems is as a habitat for marine organisms. Benthos is a group of marine biota that lives on the bottom of the waters and can be found in seagrass ecosystems. This study aims to inventory the diversity of benthic organisms in seagrass ecosystems in Liki, Befondi and Meossu island. This research is part of the second leg of the Nusa Manggala Expedition which was held in 2018 on Liki Island, Meossu and Befondi, the northern waters of Papua.. Benthos data was collected using cores at 0 m, 50 m and 100 m on the line transect. The results of this study indicate that the highest density of seagrass is on Liki Island. In addition, 33 species of benthic organisms were found on Liki Island, 42 species on Meossu Island and 20 species on Befondi Island. The highest abundance and diversity of benthic organisms was found on Meossu Island. The dominant benthic organisms come from the gastropod class with the species having the highest abundance, Euplica scripta. Based on this research, it is suspected that there is a relationship between the condition of the seagrass ecosystem and the abundance and diversity of benthos.

Résumé :
SynopsisThe structure of the sublittoral benthic macro-invertebrate populations of the Forth estuary and firth, Scotland, is described, giving the species richness, abundance and biomass for the area from the freshwater tidal limit to the North Sea boundary. Eight faunal associations have been defined, which include classical Petersen communities in the marine area and transition associations within the estuary. The spatial distributions of the associations are predominantly the result of the physical environment, but superimposed on the effects of salinity, sediment type and bathymetry are the effects of urbanisation, industrialisation, dredging and spoil disposal and thermal discharges. The benthos of the major part of the firth has been little affected, although that of the peripheral and estuarine areas does show anthropogenic effects.The water column-benthos and fisheries-benthos interactions are also discussed. Elevated levels of nutrients in the water column may be the cause of enriched benthic populations in the firth and an assessment of the fish-benthos coupling indicates an estuarine functioning similar to other northwestern European areas.

Résumé :
The amount and diversity of phytoplankton, zooplankton and benthos are very essential indexes for the marine ecology. These indexes are meaningful guidance for the regional management, sustainable development and ecological civilization. In this paper, the trend of marine ecology is researched for guiding and improve the environmental impact assessment and management in the Caofeidian marine district, Tangshan Bay. The amount and diversity of phytoplankton, zooplankton and benthos are analyzed by five years’ field data. The research results show that the marine reclamation has influence on the marine ecology.

Résumé :
Modern marine plankton communities include a broad diversity of metazoans that are suspension-feeding or micropredatory as adults. Many benthic marine species have larval stages that reside, and often feed, in the plankton for brief to very long periods of time, and most marine benthic communities include large numbers of suspension-feeders. This has not always been the case. Cambrian benthic communities included relatively few suspension-feeders. Similarly, there were few metazoan clades represented in the plankton, either as adult suspension-feeders or as larvae. Review of the fossil record suggests that the diversification of the plankton and suspension-feeding marine animals began in the Late Cambrian and continued into the Ordovician. These changes were accompanied by, and probably influenced, concurrent major changes in the marine realm, including an increase in tiering within benthic communities, the replacement of the Cambrian fauna by the Paleozoic fauna, and a general taxonomic diversification. The ultimate cause of these changes is uncertain, but it appears likely that the plankton was and is a refuge from predation and bioturbation for adults and larvae alike. The expansion in plankton biomass thus provided increased ecological opportunities for suspension-feeders in the plankton and benthos.

Résumé :
The stomach contents of demersal fish in late January 1982 were analysed. Samples were taken at 100, 300 and 500 m depth south of Elephant Island, Bransfield Strait and north of Livingston Island, and at 800 m to the east of Smith Island. Fifty four taxa of fish belonging to 11 families were collected. The diets of 2101 fish representing 38 taxa were examined. These were classified into three categories, fish feeders, krill feeders and benthos feeders. Fish prey species fed on krill and/or benthos. Krill was a major dietary component for 32 (84.2%) out of 38 taxa. Gobionotothen gibberifrons was distributed at all 10 stations (100–800 m in depth) and its diet comprised krill and benthos. The present findings verify the importance of krill in the Antarctic marine ecosystem and indicate that krill is consumed by benthic fish at greater depths than previously reported.

Résumé :
Many Antarctic marine benthic macroinvertebrates are chemically protected against predation by marine natural products of different types. Antarctic potential predators mostly include sea stars (macropredators) and amphipod crustaceans (micropredators) living in the same areas (sympatric). Recently, alien species (allopatric) have been reported to reach the Antarctic coasts, while deep-water crabs are suggested to be more often present in shallower waters. We decided to investigate the effect of the chemical defenses of 29 representative Antarctic marine benthic macroinvertebrates from seven different phyla against predation by using non-native allopatric generalist predators as a proxy for potential alien species. The Antarctic species tested included 14 Porifera, two Cnidaria, two Annelida, one Nemertea, two Bryozooa, three Echinodermata, and five Chordata (Tunicata). Most of these Antarctic marine benthic macroinvertebrates were chemically protected against an allopatric generalist amphipod but not against an allopatric generalist crab from temperate waters. Therefore, both a possible recolonization of large crabs from deep waters or an invasion of non-native generalist crab species could potentially alter the fundamental nature of these communities forever since chemical defenses would not be effective against them. This, together with the increasing temperatures that elevate the probability of alien species surviving, is a huge threat to Antarctic marine benthos.

Résumé :
Severe climatic and environmental changes are far more prevalent in Earth history than major extinction events, and the relationship between environmental change and extinction severity has important implications for the outcome of the ongoing anthropogenic extinction event. The response of mineralized marine plankton to environmental change offers an interesting contrast to the overall record of marine biota, which is dominated by benthic invertebrates. Here, we summarize changes in the species diversity of planktic foraminifera and calcareous nannoplankton over the Mesozoic–Cenozoic and that of radiolarians and diatoms over the Cenozoic. We find that, aside from the Triassic–Jurassic and Cretaceous–Paleogene mass extinction events, extinction in the plankton is decoupled from that in the benthos. Extinction in the plankton appears to be driven primarily by majorclimatic shifts affecting water column stratification, temperature, and, perhaps, chemistry. Changes that strongly affect the benthos, such as acidification and anoxia, have little effect on the plankton or are associated with radiation. ▪ Fossilizing marine plankton provide some of the most highly temporally and taxonomically resolved records of biodiversity since the Mesozoic. ▪ The record of extinction and origination in the plankton differs from the overall marine biodiversity record in revealing ways. ▪ Changes to water column stratification and global circulation are the main drivers of plankton diversity. ▪ Anoxia, acidification, and eutrophication (which strongly influence total marine fossil diversity) are less important in the plankton.

Résumé :
The last two decades have seen a shift of emphasis in ecology; from a focus on the drivers of biodiversity change toward a consideration for its effects on ecosystem functioning. Ecosystem functioning is affected by individual species (i.e. species with functionally dominant biological traits), but can also be influenced by other factors, such as interspecific interactions. Current evidence suggests that biotic influence over marine ecosystem functioning is largely underpinned by the effects of individual species. However, there are indications that this might not constitute a complete understanding of the link between marine biodiversity and ecosystem function (BEF). For this thesis, I applied our current understanding of marine BEF relationships (i.e. the causal link between particular biological traits and particular ecological functions) to long-term benthic community time series and investigated the causes of ecological change and its consequences for ecosystem functioning. A shift in the taxonomic composition of the species assemblage was explained by underlying variation in extrinsic drivers. However, the long-term conservation of trait composition suggests that functioning can be sustained in the face of environmental and ecological change. Experiments conducted to test BEF relationships in intertidal marine benthos reaffirmed the functional importance of the biological traits of species, but also showed that interactions among species can influence the delivery of ecological functions in various ways, including facilitation (i.e. function delivery is enhanced) and antagonism (i.e. function delivery is reduced). The results suggest that biotic influence over marine ecosystem functioning is more complex than previously suggested, and that the impacts of biodiversity change (e.g. species extinctions or shifts in species densities) could be either exacerbated or mitigated depending on the composition of the affected assemblage and the ecological function considered. To produce more realistic results, future indirect assessments of ecosystem functioning would benefit from incorporating interactions among species as well as their biological traits.

Briozoários são organismos sésseis e coloniais, que dependem de uma superfície firme para assentamento larval e crescimento da colônia. Entre os diferentes substratos disponíveis para briozoários, as esponjas podem oferecer uma superfície favorável, trazendo muitas vantagens como a presença de compostos químicos que inibem a predação. Este estudo verificou a presença de briozoários em seis espécies de esponjas, com finalidade de avaliar a abundância e riqueza desses briozoários em diferentes esponjas. Três espécimes das esponjas, Amphimedon compressa Duchassaing & Michelotti, 1864, Amphimedon viridis Duchassaing & Michelotti, 1864, Desmapsamma anchorata (Carter, 1882), Dysidea etheria de Laubenfels, 1936, Haliclona implexiformis (Hechtel, 1965) e Tedania ignis (Duchassaing & Michelotti, 1864) foram coletadas mensalmente entre setembro de 2014 e fevereiro de 2016, em Pontas de Pedra, Pernambuco, Brasil. Os briozoários encontrados foram identificados até o menor nível taxonômico possível e quantificados. Um total de 324 espécimes de esponjas foi analisado, no qual destas 88 apresentavam briozoários em sua superfície (27%). Onze espécies de briozoários pertencentes à Classe Gymnolaemata foram encontrados nas esponjas, sendo quatro pertencentes à Ordem Ctenostomata, Amathia distans Busk, 1886, Amathia verticillata (delle Chiaje, 1822), Amathia vidovici Heller,1867 e Nolella stipata Gosse, 1855, sete da Ordem Cheilostomata, Beania klugei Cook, 1968, Catenicella uberrima (Harmer, 1957), Caulibugula dendograpta (Waters, 1913), Licornia sp., Savignyella lafontii (Audoin, 1826), Synnotum aegyptiacum Canu & Bassler, 1928 e Thalamoporella floridana Osburn, 1940. Briozoários foram abundantes nas esponjas Te. ignis e De. anchorata e pouco frequentes em Ap. compressa e Ap. viridis. Desmapsamma anchorata e Te. ignis apresentaram a maior riqueza de espécies (nove espécies em cada esponja), seguida por Dy. etheria (sete espécies). Uma baixa riqueza de espécies foi observada em Ap. compressa, com apenas três espécies de briozoários, Ap. viridis com quatro espécies, e H. implexiformis com cinco espécies. Apenas o briozoário N. stipata foi encontrado em todas as espécies de esponjas, enquanto que At. distans e At. vidovici não foram encontradas apenas em Ap. compressa. Uma maior riqueza e abundancia de briozoários foram encontradas em De. anchorata e Te. ignis, que apresentam superfície lisa e aveludada, e lisa e vilosa, respectivamente. Por outro lado, superfície lisa também é característica das espécies Ap. compressa e Ap. viridis, que apresentaram a menor frequência e diversidade de briozoários. Adicionalmente, as esponjas De. anchorata e Dy. etheria que apresentam superfície lisa e conulosa, respectivamente, compartilharam grande parte das espécies encontradas. A presença de metabólitos secundários nas esponjas do gênero Amphimedon que apresentam toxicidade já descrita na literatura, pode ter influenciado na ocorrência dos briozoários. Enquanto que as esponjas Te. Ignis, De. anchorata e Dy. Etheria, que apresentaram uma grande abundância de briozoários, podem ter provido um microhabitat adequado para os briozoários da região. O padrão temporal de ocorrência dos briozoários nas esponjas durante os 18 meses de coleta foi aleatório. O presente trabalho permite identificar alguns padrões da ocorrência dos briozoários, relacionado a composição química das esponjas e sua posição no substrato.
Bryozoans comprise sessile, colonial organisms that require a hard surface for settlement and growth. Among different substrata for bryozoans, sponges may provide suitable substrata, with advantages such as presence of compounds against predators. This study analyses the bryozoan community on six sponges species throughout 18 months, to evaluate the presence of bryozoans on its surface. Three specimens of each sponges, Amphimedon compressa Duchassaing & Michelotti, 1864, Amphimedon viridis Duchassaing & Michelotti, 1864, Desmapsamma anchorata (Carter, 1882), Dysidea etheria de Laubenfels, 1936, Haliclona implexiformis (Hechtel, 1965) and Tedania ignis (Duchassaing & Michelotti, 1864), were taken monthly betweem September 2014 to February 2016, in Pontas de Pedra, Pernambuco State, Brazil. Bryozoans were identified to the lowest taxonomic level, and quantified. Total of 324 specimens of sponges were analysed, 88 from those were found bryozoans on its surface (27%). Eleven gymnolaemate bryozoans were found on sponges being four of the Order Ctenostomata, Amathia distans Busk, 1886, Amathia verticillata (delle Chiaje, 1822), Amathia vidovici Heller,1867 and Nolella stipata Gosse, 1855, and seven species Cheilostomata, Beania klugei Cook, 1968, Catenicella uberrima (Harmer, 1957), Caulibugula dendograpta (Waters, 1913), Licornia sp., Savignyella lafontii (Audoin, 1826), Synnotum aegyptiacum Canu & Bassler, 1928 and Thalamoporella floridana Osburn, 1940. Bryozoans were considered abundant on the sponges Te. ignis and De. anchorata, but few frequents on Ap. compressa and Ap. viridis. On De. anchorata and Te. ignis were found the highest bryozoan richness (9 species of bryozoan per sponge species), followed by Dy. etheria (7 bryozoan species). A low species richness was observed in Ap. compressa, Ap. viridis and H. implexiformis with respectively three, four and five species of bryozoans on their surface. Only N. stipata was found on the six sponge species, while At. distans and At. vidovici were not found only on Ap. compressa. Higher richness and abundance of bryozoans were found in De. anchorata and Te. ignis, with smooth and velvety surface, smooth and villous surface, respectively. Smooth surface is also characteristic of Ap. compressa and Ap. viridis, with the lowest frequency and diversity of bryozoans. Additionally, on sponges De. anchorata and Dy. etheria, with smooth and conulose surface respectively, were shared the majority of bryozoan species. We suggest the presence of secondary metabolites may have interfered the bryozoans on sponges of Amphimedon genus. Sponges Te. ignis, De. anchorata and Dy. etheria, have an abundance of bryozoans; thus, we suggest these sponges may allow a suitable substratum for the bryozoans. The temporal variation of bryozoans on sponges was random. In present work some patterns of occurrence of bryozoans are presented, with relation to the chemical composition and position of sponge.

Résumé :
Extending into the Arabian Gulf, Qatar is surrounded by a number of islands mostly scattered by the eastern coastline. With the unique physical characteristics of the Gulf, which is a highly saline sea with high seawater temperatures, there is an urge need to investigate the macroalgae living in such harsh environment. Macroalgae plays an important role in the food web as they are primary producers and providers of food for other organisms. They also provide shelter and habitat in the marine ecosystem for herbivorous fish and other invertebrate animals. Additionally, macroalgae plays an outstanding role in reducing CO2 from the atmosphere and increasing the level of dissolved oxygen in their immediate environment. However, there are few studies on marine macroalgae in Qatar and no previous studies found related to macroalgae from the islands around Qatar. The present work contributes to the macroalgae research by providing the first survey of distribution and diversity of benthic marine macroalgae in islands around Qatar. The marine benthic green, red and brown macroalgae of intertidal and subtidal in marine zone areas around Qatar were collected during Qatar’s Islands project, which started 2018. The collected macroalgae are documented and a total of 67 species of macroalgae are recorded for all islands around Qatar, 24 Chlorophyta (Green algae), 25 Rhodophyta (Red algae) and 18 species Phaeophyta (Brown algae). The Red algae are dominant taxon in term of species richness, accounting for an average of 37% of the species at all study sites. The islands which had more species are Al-Beshaireya 58 Species, Al-Aaliya 53 Species, Sheraouh 48 Species, Janan 43 Species and Bu Felaita 37 Species. Our results show that islands located at eastern and southeastern coast of Qatar have more diversity of algae species than those located at the western and northwestern coast.

Résumé :
The exclusive economic zone (EEZ) of Japan has a very wide area due to a lot of islands in the Japanese Archipelago. Recently, the development of power generation facilities, food production facilities, and the natural resources in the Japanese EEZ are planned. As the worldwide supply and demand of mineral resources are being tight, the technology for effective exploitation and the use of mineral resources in the EEZ will become a key for sustainable development in the Japanese industry. Prior to development of marine mineral resources, it is necessary to evaluate its environmental impact on the water column and seafloor of ocean. However, the environmental evaluation method for open ocean has not been established yet. Then, we are developing the environmental impact prediction model for the seafloor mineral resources development in deep sea area with the consideration of benthic organisms. This model can estimate the impacts of excavating seafloor and sedimentation of particles on marine organisms using an ecosystem model. In addition, the influence of an increase in dissolved oxygen on bacteria caused by the discharging of oxygen-rich waste water at seafloor, is considered in this model. The ecosystem in this model includes benthic organisms, zooplankton, bacteria, particulate organic matter and dissolved oxygen as the components. This paper introduces the calculation case using the prototype model.

Résumé :
The accelerating Arctic cryosphere decline severely impacts the land on which northern communities live through the presence of coastal and marine geohazards and coastal erosion, which further places the cultural heritage of coastal archaeological sites at risks. Sea ice decline also compromises the formation of polynyas, with unknown consequences for the regional ecosystems. From the 10th to the 18th of July 2022, a scientific cruise onboard the research vessel William-Kennedy allowed the collection of a suite of samples and data from the marine coastal environment of Nain, Nunatsiavut. In total, 42 surface sediment samples, 29 sediment cores, 41 conductivity-temperature-depth (CTD) profiles, 13 water samples, 24 phytoplankton nets and 13 zooplankton nets were collected. The cruise allowed the deployment of 2 moorings equipped with sediment traps in Nain Bay and within deeper offshore waters. Triangulation showed that the 2 moorings were correctly placed near their target locations. Drop camera transects were deployed in Webb Bay and at the easternmost tip of Paulmp;gt;'s Island to image the seabed and study benthic habitats. Finally, acoustic sub-bottom profiling along the entire study area allowed a high-resolution characterization of the stratigraphy of the seafloor, helped identifying locations for sediment sampling and inferring geological information about the depositional environments. The material and data collected during the research cruise will be key to 1) evaluating the productivity and dynamics of small recurring polynyas (i.e., rattles) on diverse timescales, 2) assessing marine and coastal geohazards (e.g., landslides) in relation to the deglacial history of Nain, 3) investigate the seabed geomorphology in Webb Bay and linkages with permafrost and sea-level changes and 3) conducting benthic habitat characterization. Co-led by the University of New Brunswick (UNB) and Natural Resources Canada (NRCan), this cruise was done in collaboration with the Government of Nunatsiavut, Université du Québec à Montréal, Université Laval, Dalhousie University and Memorial University, and was funded by the Natural Sciences and Engineering Research Council of Canada (NSERC) and NRCan.

Résumé :
DIPLANOAGAP: Distribution of Plastics in the North Atlantic Garbage Patch Ponta Delgada (Portugal) – Malaga (Spain) 17.08. – 12.09.2019 The expedition POS 536 is part of a multi-disciplinary research initiative of GEOMAR investigating the origin, transport and fate of plastic debris from estuaries to the oceanic garbage patches. The main focus will be on the vertical transfer of plastic debris from the surface and near-surface waters to the deep sea and on the processes that mediate this transport. The obtained data will help to develop quantitative models that provide information about the level of plastic pollution in the different compartments of the open ocean (surface, water column, seafloor). Furthermore, the effects of plastic debris on marine organisms in the open ocean will be assessed. The cruise will provide data about the: (1) abundance of plastic debris with a minimum size of 100 μm as well as the composition of polymer types in the water column at different depths from the sea surface to the seafloor including the sediment, (2) abundance and composition of plastic debris in organic aggregates (“marine snow”), (3) in pelagic and benthic organisms (invertebrates and fish) and in fecal pellets, (4) abundance and the identity of biofoulers (bacteria, protozoans and metazoans) on the surface of plastic debris from different water depths, (5) identification of chemical compounds (“additives”) in the plastic debris and in water samples.
