Nocturnal feeding under artificial light conditions by Brown-Hooded Gull (Larus Maculipennis) in Puerto Madryn harbour (Chubut province, Argentina)
Provedor de dados: 68
Autores: Leopold,Mardik F.; Philippart,Catharina J. M.; Yorio,Pablo.
This paper describes nocturnal, marine feeding behaviour in the Brown-hooded Gull (Larus maculipennis) in November 2009. The gulls assembled at night at the end of a long pier, running 800 m offshore into the Golfo Nuevo, at Puerto Madryn, Chubut Province, Argentina. Powerful lights predictably lighted the water around the end of the pier and attracted many small prey animals to the surface. Several hundreds of gulls, presumed to be local breeders, came every night to feed on this bounty, using various feeding techniques and taking several prey species and sizes. Potential prey items were caught to be identified by vertical plankton hauls. The gulls most likely took relatively large Isopoda (Idothea sp.), Polychaeta (Platynereis sp.) and fish larvae...

Adult somatic progenitor cells and hematopoiesis in oysters
Provedor de dados: 5
Autores: Jemaa, Mohamed; Morin, Nathalie; Cavelier, Patricia; Cau, Julien; Strub, Jean Marc; Delsert, Claude.
Long-lived animals show a non-observable age-related decline in immune defense, which is provided by blood cells that derive from self-renewing stem cells. The oldest living animals are bivalves. Yet, the origin of hemocytes, the cells involved in innate immunity, is unknown in bivalves and current knowledge about mollusk adult somatic stem cells is scarce. Here we identify a population of adult somatic precursor cells and show their differentiation into hemocytes. Oyster gill contains an as yet unreported irregularly folded structure (IFS) with stem-like cells bathing into the hemolymph. BrdU labeling revealed that the stem-like cells in the gill epithelium and in the nearby hemolymph replicate DNA. Proliferation of this cell population was further...

Marine invertebrate fauna of the Chausey archipelago: an annotated checklist of historical data from 1828 to 2008
Provedor de dados: 5
Autores: Godet, Laurent; Le Mao, Patrick; Grant, Cindy; Olivier, Frederic.
The first updated list of the marine invertebrate fauna of the Chausey archipelago (Normand-Breton Gulf, France) is presented. All publications regarding the natural history of the area, as well as the existing collections of marine invertebrates from 1828 to 2008 were examined. A total of 769 species (including 245 Arthropoda, 197 Mollusca, 146 Polychaeta), have been recorded in this area covering 5000 ha. This species richness is largely the result of the complexity of benthic habitatsof the archipelago and its long history of field work, dating back to the 19(th) Century. The historical data set of this region presents an opportunity to assess long-term changes in nearshore communities and to design conservation sites based on their scientific value.

Ciguatera poisoning in French Polynesia: insights into the novel trends of an ancient disease
Provedor de dados: 5
Autores: Chinain, M.; Gatti, C.m.; Roué, M.; Darius, H.t.
Ciguatera is a non-bacterial seafood poisoning highly prevalent in French Polynesia where it constitutes a major health issue and a major threat to food sustainability and food security for local populations. Ciguatera results from the bioaccumulation in marine food webs of toxins known as ciguatoxins, originating from benthic dinoflagellates in the genera Gambierdiscus and Fukuyoa. Ciguatera is characterized by a complex array of gastrointestinal, neurological and cardiovascular symptoms. The effective management of patients is significantly hampered by the occurrence of atypical forms and/or chronic sequelae in some patients, and the lack of both a confirmatory diagnosis test and a specific antidote. In addition, recent findings have outlined the...

The role of astaxanthin in shrimp pigmentation
Provedor de dados: 5
Autores: Latscha, T.
Carotenoids are exogenously derived isoprenoid compounds which are responsible for pigmentation in crustaceans. While implants and bacteria are able to synthesize these carotenoids de novo, shrimps like other animals entirely depend on their dietary supply. The major carotenoid found in most crustacean tissues and responsible, e.g. for the typical colour of penaeids is astaxanthin. With increasing industrialization in shrimp farming there is a growing demand for synthetic, nature-identical carotenoids, not only for pigmentation, but also for the maintenance of growth and fertility.

Tracing carbon assimilation in endosymbiotic deep-sea hydrothermal vent Mytilid fatty acids by C-13-fingerprinting
Provedor de dados: 5
Autores: Riou, V.; Bouillon, S.; Serrao Santos, R.; Dehairs, F.; Colaco, A.
Bathymodiolus azoricus mussels thrive at Mid-Atlantic Ridge hydrothermal vents, where part of their energy requirements are met via an endosymbiotic association with chemolithotrophic and methanotrophic bacteria. In an effort to describe phenotypic characteristics of the two bacterial endosymbionts and to assess their ability to assimilate CO2, CH4 and multi-carbon compounds, we performed experiments in aquaria using C-13-labeled NaHCO3 (in the presence of H2S), CH4 or amino-acids and traced the incorporation of C-13 into total and phospholipid fatty acids (tFA and PLFA, respectively). 14:0; 15:0; 16:0; 16:1(n - 7) c+t; 18:1(n - 13) c+t and (n - 7) c+t; 20:1(n - 7); 20:2(n - 9,15); 18:3(n - 7) and (n - 5,10,13) PLFA were labeled in the presence of...

Early gametogenesis in the Pacific oyster: new insights using stem cell and mitotic markers
Provedor de dados: 5
Autores: Cavelier, Patricia; Cau, Julien; Morin, Nathalie; Delsert, Claude.
While our knowledge of bivalve gametogenesis has progressed in recent times, more molecular markers are needed in order to develop tissue imaging. Here, we identified stem cell and mitotic markers to further characterize oyster early gametogenesis, mainly through immunofluorescence microscopy. Intense alkaline phosphatase activity, a non-specific marker for stem cells, was detected on the outer edge of the gonad ducts at the post-spawning stage, suggesting an abundance of undifferentiated cells very early during the sexual cycle. This observation was confirmed using an antibody against Sox2, a transcription factor specific for stem or germline cells, which labeled cells in the gonad duct inner mass and ciliated epithelium early during the initial oyster...

Typically, coral reefs are dominated by sedentary colonial organisms. Species compositions are temporally and spatially dynamic and populations may be seen to interact through similar mechanisms as those observed in terrestrial plant communities. In these areas, intense competition for limited niche space, selects for varied defensive and offensive strategies and reproductive life history traits.

A simple volumeter for small invertebrates
Provedor de dados: 27
Autores: Persoone, G.
The displacement technique for measuring the volume of plankton catches is well established, and a number of papers have been published describing suitable apparatus for this purpose including those by Frolander (1957), and Yentsch &amp; Hebard (1957). Gnanamuthu (1952) reviews several papers dealing with equipment for measuring the volume of small aquatic animals and discusses his own volumeter. The apparatus here described employs a water column and is, therefore, more convenient to handle than previous designs which used a mercury column. It is inexpensive and simple to construct, and will measure to 0.01 or even 0.005 ccm. We have found it most useful in quickly measuring the volume of polychaetes or oligochaetes, small bivalves, small crustaceans, etc.

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...

Three simple culture devices for aquatic invertebrates and fish larvae with continuous recirculation of the medium
Provedor de dados: 27
Autores: Sorgeloos, P.; Persoone, G.
The 3 culturing devices described are based on the principle of the classic air-water lift, which facilitates continuous recirculation and aeration of the cultivation medium. The first device is a "circulation cylinder", convenient for hatching eggs of the brine shrimp &lt;i&gt;Artemia salina&lt;/i&gt; and for culturing algae and protozoans. In the second device, an internal basket (i.e., a glass cylinder with plankton-gauze bottom) prevents the animals being carried along in the air-water lift. The third device, analogous to the second, is provided with a lateral waste-drain and a water collector with siphon, which empties regularly into the main culture vessel. The second and third devices proved to be excellent for the cultivation of a variety of...

Development of a flow-through system for the study of toxicity and bioaccumulation processes in aquatic invertebrates
Provedor de dados: 27
Autores: Blust, R.; Decleir, W.
A flow-through test system for the study of toxicity and bioaccumulation processes is described. The apparatus can operate within a very wide range of flow rates. Flow deviations are less than 2% and the variation in test-agent concentration, (determined for copper) ranges from 3 to 8%. As a practical test a copper-toxicity experiment on adult &lt;i&gt;Artemia&lt;/i&gt; was carried out and the results compared with data obtained from a similar but static assay. The results indicate that: - bioassay and accumulation experiments must preferably be carried out under flow-through conditions to keep the concentration and bioavailability of the toxicant as constant as possible;- the data analysis must be based upon measured test-solution toxicant-concentrations...

TOWARDS A REVIEW OF THE DECAPOD CRUSTACEA FROM THE REMOTE OCEANIC ARCHIPELAGO OF TRINDADE AND MARTIN VAZ, SOUTH ATLANTIC OCEAN: NEW RECORDS AND NOTES ON ECOLOGY AND ZOOGEOGRAPHY
Provedor de dados: 84
Autores: TAVARES,MARCOS; CARVALHO,LEINA; MENDONÇA JR.,JOEL BRAGA DE.
ABSTRACT The remoteness of the Trindade and Martin Vaz young volcanic archipelago (TMV) raises questions about the source of its marine benthic fauna and levels of endemism. Addressing these questions requires a comprehensive knowledge of the taxonomic composition of the marine fauna of the islands. A five-year survey in the shallow marine waters (up to 30 m) and a literature review on the data published for TMV have been conducted to document the biodiversity of the benthic fauna. Here we report on ten new records of decapod crustaceans from TMV: Gnathophyllum americanum and Thor amboinensis are circumtropical in distribution, whereas Stenopus hispidus, Gnathophylloides mineri and Parribacus antarcticus are disjunct circumtropical species as their...

Brood care in Brachyuran crabs: the effect of oxygen provision on reproductive costs
Provedor de dados: 97
Autores: FERNÁNDEZ,MIRIAM; BRANTE,ANTONIO.
The quantification of the costs associated with parental care of marine invertebrates requires a first and necessary step, which is the identification of the different forms of care exhibited by this group. Among marine invertebrates, provision of oxygen to the aggregation of embryos may be critical, although most evidence on the link between oxygen limitation and parental care is indirect. Species which show active behavior directed at providing oxygen to the brood offer a good model to establish the direct link between behavioural patterns and oxygen provision to the embryos, and to estimate the costs associated with this form of care. In this manuscript, we conducted a review of the current knowledge about oxygen limitation in embryos aggregations of...

Population structure of the lancelet Branchiostoma caribaeum (Cephalochordata: Branchiostomidae) in the Baía de Guanabara, Rio de Janeiro, southeastern Brazil
Provedor de dados: 104
Autores: Silva,Luis F. B. da; Tavares,Marcos; Soares-Gomes,Abilio.
Population structure of the lancelet Branchiostoma caribaeum Sandevall, 1853 was studied in four surveys, corresponding to austral seasons, in a tropical bay, southeast of Brazil. Abundance was higher in the spring and was positively correlated to coarse sediments, limiting its occurrence to some sectors of the sampling area. Body length and biomass differed seasonally but not between sexes. Sexually mature individuals occurred in all seasons, suggesting continuous breeding that is typical of tropical species. Variation in the frequency of small specimens indicates temporal differences in the intensity of breeding. The body length of recruits differed from other population of lancelets and the small length which B. caribaeum attained sexual maturity in...

The first finding of Ostrea cf. puelchana (Bivalvia) living as epibiont on Callinectes exasperates (Decapoda)
Provedor de dados: 3
Autores: Lima, Silvio Felipe Barbosa; Lucena, Rudá Amorim; Queiroz, Vinicius; Guimarães, Carmen Regina Parisotto; Breves, André.
 This paper describes the epibiosis of Ostrea cf. puelchana on Callinectes exasperatus (Gerstaecker, 1856), both collected from the estuary of the Paraíba River, in the state of Paraíba, northeastern Brazil. The basibiont crab was captured using a trap installed in mangrove area at a depth of about 2 meters. The oyster was closely attached to the left side of dorsal carapace covering most of the epibranchial, mesobranchial and metabranchial regions. Possible advantages and disadvantages for both the epibiont and the basibiont are discussed. We believe that young O. cf. puelchana may avoid a variety of potential predators due to the considerable movement capacity of C. exasperatus and may also serve as a small protective shield for the basibiont. However,...

Sessile and sedentary macrofauna from the Pirapama Shipwreck, Pernambuco, Brazil
Provedor de dados: 49
Autores: Lira,Simone Maria de Albuquerque; Farrapeira,Cristiane Maria Rocha; Amaral,Fernanda Maria Duarte; Ramos,Carla Alecrim Colaço.
Shipwrecks are considered artificial reef environments - structures immersed in aquatic environments (especially marine ones) that provide fauna with shelter, hard substrates, food and nursery areas. This study aimed to survey the benthic animal biodiversity of the Pirapama shipwreck, located 23 m deep and six miles off Recife harbor. From 2001 to 2007, species were observed, photographed and collected through scuba diving. The material was later sorted and identified in the laboratory. A total of 76 sessile and sedentary animal taxa were recorded belonging to the following phyla: Porifera (Demospongiae and Calcarea), Cnidaria (Hydrozoa and Anthozoa), Mollusca (Bivalvia and Gastropoda), Annelida (Polychaeta), Arthropoda (Cirripedia), Bryozoa...

Native species exploited by marine aquarium trade in Brazil
Provedor de dados: 49
Autores: Gurjão,Lívio Moreira de; Lotufo,Tito Monteiro da Cruz.
Abstract: Brazil has an important role in marine ornamental trade, exploiting native species for both international and domestic market. A few works have previously assessed wild species exploited by the Brazilian marine aquarium industry and most of them focused solely on fish. Hence, the present paper intends to address an information gap regarding the species currently traded in the country, as well as concerning their conservation statuses. Thus, different sources of information were investigated and each species was categorized in accordance with existing lists of threatened species. A wide variety of native species was identified in Brazilian marine aquarium trade, including not only fish but also invertebrates, seaweeds and macrophytes. Some of...
