Última Tramas tróficas en sistemas frontales del Mar Argentino: estructura, dinámica y complejidad analizada mediante isótopos estables OceanDocs Gaitán, E.N.. Two of the most important frontal systems of the Argentine Sea (SW Atlantic Ocean) were compared to obtain evidences on the regulatory mechanisms of food web length, incorporating both spatial (areas within fronts) and temporal (presence or absence of frontal structure) variability. The stable isotopes of Carbon and Nitrogen were used to evaluate the origin and composition of the organic matter used by primary consumers, the structure of food webs, the trophic levels of several taxa and the benthic-pelagic coupling within each system. In the Río de la Plata estuarine front, different sources of organic matter would support the food webs occurring in the three areas of the system. The particulate organic material (POM) would be the main resource supporting...

Ano: 2012 URL: http://hdl.handle.net/1834/4523 Historia de vida temprana de la corvina rubia (Micropogonias furnieri, Sciaenidae) en el Estuario del Río de La Plata OceanDocs Braverman, M.. This study encompasses the bio-physical interactions of whitemouth croaker (Micropogonias furnieri) early life stages living in La Plata estuary (Argentina-Uruguay, South America) to understand how they take advantage of the estuarine dynamics while traveling from spawning to nursery areas and undergoing ontogenetic and associated ecological changes. The analyses used include studies of spatio-temporal distribution length-dependent patterns; growth patterns looking for settlement marks in otoliths; and development related to metamorphosis and ontogenetic variations of the diet and trophic level. Samples and data come from vertically stratified samplings from 3 cruises (2005, 2006 and 2009). Distributional data also comes from an historic database. Results...
