Dinámica del ultrafitoplancton en el Mar Argentino
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Silva, R.I.
Ultraphytoplankton is composed by a group of organisms phylogenetically diverse, which contribute significantly to the total biomass and primary production in different oceanic and coastal pelagic systems. The success of ultraphytoplankton is attributed to its high efficiency in capturing light and nutrients, due to their small cell size and low sinking rate. The community structure is driven by the interaction among biotic and abiotic variables, such as temperature, nutrients, light and predators. The objective of this work was to assess the ecological importance of ultraphytoplankton organisms at the EPEA station, situated in the Buenos Aires coastal pelagic system (Argentina, SW Atlantic), during the period 2000-2009. In particular, ultraphytoplankton...

Estructura de la comunidad del fitoplancton en el área de El Rincón, Mar Argentino (febrero 2011)

The El Rincón area in the Argentine continental shelf (coastal sector between 39º S-41º S) is known as one of the main breeding areas of the Argentine anchovy (Engraulis anchoita) Northern stock. However, there is scarce information regarding the structure of the primary producers, base of the pelagic food webs. The aim of this study was to identify the different phytoplanktonic communities in a coastal section in the area (depth lower than 60 m) during February 2011. Mean surface chlorophyll a concentration was 0.72 mg m-3, with the highest value in the innermost station (E34: 1.84 mg m-3) and the lowest in the mid section (E31: 0.24 mg m-3). In depth, similar concentrations were registered, except for the deepest station where the maximum value was...
