Recently, CO2 recycling for the production of valuable microalgae has acquired substantial interest. Most studies investigating CO2 conversion efficiency in algal cultures were based on single species, although a stabilising effect of algal diversity on biomass production was recently highlighted. However, addition of CO2 into polyalgal cultures requires a careful control of pH; performance of CO2 conversion, growth and carbon biomass production are affected by pH differently, depending on the species of microalgae. This study investigates the efficiency of CO2 conversion by natural marine algal assemblage cultivated in open, land-based raceways (4.5 m3, 10 m2), working as high rate algal ponds (HRAP). Ponds were enriched with nitrogen and phosphate, pure... Tipo: Text Palavras-chave: Carbon yield; Microalgal diversity; PH; Predators.

This study deals with rearing methods, growth and mortality performances, and problems encountered by the oyster farmers from Quiberon Bay (2800 ha of leases) : it relies on a survey achieved in july 2001, about 18 oyster farmers, and 2 diving campaigns (july and october 2001) on 2 years old oyster batches from the same farmers. The analysed enterprises vary in particular by the location and depth of their concession inside the bay, but also by their rearing scheme : a majority favours seedings with 18 month old oysters or more, according to prices and availability of oysters supplies. The duration until marketable size and mean mortalities seem to have increased since a preceding inquiry in 1986. The main constraint, affecting priorly the south border...

Several studies focused on wastewater treatment in High Rate Algal Ponds (HRAP) suggest that highly variable climatic conditions cause large variations of microalgal biomass productivity. In the present study, we show that similar carbon, nitrogen and phosphorus removal efficiencies were reached in different HRAPs treating urban wastewaters located in two different temperate (Mediterranean and oceanic) climates. Furthermore, similar ecological successions were observed in these HRAPs. During the start-up phase, the consumption of organic matter by detritivores, already present in the wastewater, appears to be necessary for the microalgae to grow within two weeks in spring. The growth of the rapid-growing species, Chlorella sp., followed by the... Tipo: Text Palavras-chave: Microalgae; Predators; Bacteria; Urban effluents; Ammonia and phosphate removal. Ano: 2019 URL: https://archimer.ifremer.fr/doc/00490/60210/63713.pdf Factors affecting bacterial biomass and growth in the Duplin River estuary and coastal Atlantic Ocean. ArchiMer Fallon, R; Newell, S; Sherr, B; Sheer, E. Bacterial numbers and growth rates were measured in coastal, planktonic systems of the Western Atlantic ocean. Seasonal responses in growth rates of the bacterial assemblage were present at some sites, but these may be related to seasonal changes in substrate supply rather than to changes in temperature. Bacterial growth rates tended to decline with increasing distance from shore. There was evidence for predator-prey population cycles in the bacteria and < 17 mu m protozoa in the Duplin River Estuary which may indicate that the bacterial assemblage serves as prey for protozoan populations. In summer, a significant negative correlation between mu (instantaneous growth rate) and cell numbers in the bacterial assemblage indicated that substrate limitation...

Several polyphagous arthropod predators are commercially available for augmentative biological control targeting mite and insect pests in a variety of cropping systems. A number of these predators are not native to the area of release. The current paper discusses benefits and risks of using exotic generalist predators as biocontrol agents. The fact that polyphagous predators are easily reared on unnatural foods and can be used against different pest species makes them attractive for commercialization. Polyphagous or facultatively phytophagous predators have less difficulty in maintaining their populations at low prey densities and can sometimes be introduced in the crop before the target pest is present, thus preventing the buildup of pest populations...

We examined the diet of 4 annual fishes, Austrolebias viarius, Austrolebias cheradophilus, Austrolebias luteoflammulatus and Cynopoecilus melanotaenia inhabiting temporal ponds of southeastern Uruguay, by analysis of stomach contents. Fishes were captured from fifty ephemeral ponds of Castillos Lagoon basin, in the region of the Humedales del Este. We identified 13099 individual prey items extracted from 669 stomachs of the four captured species. In the studied system, annual killifishes represents the most abundant and conspicuous top predators. Killifishes are generalist key predators at the ephemeral ponds of the studied system, consuming mostly aquatic items. Zooplancton represented the bulk of the diet in the four analyzed species, followed by eggs,...

Recent range extensions of the invasive rapa whelk Rapana venosa, biological data of the population and possible ecological impacts on the food webs of the Rio de la Plata estuary are presented. A total of 41 rapa whelks and 21 egg capsules were collected between February 2004 and March 2006. Specimens were found all over the mixohaline waters of the estuary, with records off Montevideo, Samborombon Bay and off Punta Rasa. Specimens ranged between 28 and 120 mm shell length. Almost all R. venosa presented epibionts all over the shell, suggesting an exposed lifestyle. Egg-masses were attached to specimens of R. venosa, debris and plastic garbage. The spatial distribution of R. venosa within the estuary was coupled with the spatial distribution of Mactra...

Todos los organismos han desarrollado evolutivamente mecanismos que les permiten defenderse de otros, garantizar su permanencia temporalmente y evitar el ataque de depredadores. Uno de estos mecanismos es la defensa química, mediante la cual los depredadores potenciales de los organismos son disuadidos de consumir su presa. En este estudio se evaluó la capacidad disuasora de los extractos orgánicos crudos de quince esponjas marinas del Caribe colombiano, sobre el pez arrecifal generalista Stegastes partitus. Se encontró que el extracto de Cribrochalina infundibulum actuó como un atrayente para estos depredadores potenciales, mientras que sólo los extractos de las esponjas Dragmacidon reticulata, Petromica cyocaliptoides, Neopetrosia proxima, Myrmekioderma...

The comparative analysis of the food habits between top predator allows the evaluation of how these species use the trophic resources. They also make possible the study of potentially competitive relationships and the role of these predators in the regulation and structure of the community. The marine community of northern and central Patagonia is structured on the tri-trophic system composed by the Argentine anchovy (Engraulis anchoita), the Argentine shortfin squid (Illex argentinus), and Argentine hake (Merluccius hubbsi). Several marine mammals and elasmobranchs use these species as food resources. For this reason, the objective of this work was to analyze comparatively the diet of the South American sea lion (Otaria flavescens), the dusky dolphin...

For some years now the parasitic swim bladder nematode <i>Anguillicola crassus</i> of the European eel <i>Anguilla anguilla</i> L., has been reported from several European countries. The entire life history of this parasite has recently been elucidated in our laboratory. Young larvae leave the swim bladder of the host via the pneumatic duct and reach the water through the digestive tract. They are ingested by small copepods (Cyclopoida), which act as intermediate hosts. Larvae remain in the hemocoel until the copepods are eaten by the final host, the European eel. Larvae penetrate through the intestinal wall and reach the swim bladder where they develop into adults. When infected copepods are eaten by other small fish, such as carp...
