Contrasting distributional patterns of two co-occurring ctenophores in relation to ichthyoplankton and environmental features in the Southwestern Atlantic Ocean

Lucila Sobrero, Luciano M. Chiaverano, Laura Machinandiarena, Patricia Martos et autres

Assessing the ecological role of ctenophores is crucial to understanding ecosystem functioning, including the recruitment of fish stocks. During austral summer in the North Patagonia Ecosystem (NPE) (41-48°S), the ctenophores Mnemiopsis leidyi and Pleurobrachia pileus co-occur with the peak of ichthyoplankton abundance …

Detection of nearshore topographic eddies and wakes over a macrotidal coastal region. The influence of tidal currents on its generation

Juan P. Pisoni, Mariano H. Tonini, Nora G. Glembocki, Sílvia I. Romero et autres

Eddies behind headlands and islands may contribute to increased aggregation and dispersion of organisms. A regional numerical model is used for the first time to associate tidal currents with structures detected in a coastal region of Patagonia, using optical and microwave images. …

Reclutamiento de la merluza argentina, Merluccius hubbsi, del stock patagónico: una revisión de las principales características que afectan el potencial reproductivo y la supervivencia durante las primeras etapas de la vida

Gustavo J. Macchi, Gustavo Álvarez Colombo, Mauro Belleggia, Paola Betti et autres

Comprender las causas que generan la variabilidad del reclutamiento en las poblaciones marinas constituye uno de los mayores desafíos de la ciencia pesquera. Nuestra capacidad predictiva para explicar estas variaciones es relativamente baja, debido a la interacción de factores exógenos y endógenos, …

Primary production and plankton assemblages in the fisheries ground around San Jorge Gulf (Patagonia) during spring and summer

Valeria Segura, Ricardo I. Silva, Moira Luz Clara, Patricia Martos et autres

The San Jorge Gulf, and the littoral to its north, is one of the most important fishing grounds for Argentina. Nevertheless, phytoplankton production has been scarcely studied. Here we analyzed during spring (2008) and summer (2009) the phytoplankton biomass, production, and the …

Climate Variability of the Northern Argentinean Shelf Circulation: Impact on Engraulis Anchoita

Guillermo Auad, Patricia Martos

A high-resolution ocean model and hydrographic observations are used to characterize the shelf circulation of the northern Argentinean shelf during the study period (1993–2008) and ultimately to explore possible linkages among atmospheric, oceanic, and biological climatic variability. Abundance of larvae and eggs …

Seasonal and spatial variability in condition of age‐0+ Argentine hake Merluccius hubbsi Marini, 1933, in the San Jorge Gulf (Argentina): A bottom‐up perspective

Brenda Temperoni, Águeda Elena Massa, Patricia Martos, Marina Marrari

Abstract In the north Patagonian region of the Argentinean Continental Shelf, the San Jorge Gulf (SJG; 45°‐47°S, 65°30ʹ‐67°30ʹW) is the main nursery ground of age‐0+ Argentine hake Merluccius hubbsi Marini, 1933, one of the most important fishery resources in Argentina. The gulf …

On the Wind Contribution to the Variability of Ocean Currents Over Wide Continental Shelves: A Case Study on the Northern Argentine Continental Shelf

L. Lago, Martín Saraceno, Patricia Martos, Raúl Guerrero et autres

Abstract The southwestern Atlantic Ocean has one of the largest and most productive continental shelves of the southern hemisphere. Despite its relevance, its circulation patterns have been largely inferred from hydrographic observations and numerical models. Here we describe the variability of the …

Effect of nursery ground variability on condition of age 0+ year Merluccius hubbsi

Brenda Temperoni, Águeda Elena Massa, Carla Derisio, Patricia Martos et autres

This study examined the southern or Patagonian (41°-55° S) stock of Argentine hake Merluccius hubbsi, the more abundant of the two stocks on the Argentinean continental shelf. Pre-recruits (age 0+ year individuals) of this stock settle and grow in the San Jorge …

Diel vertical distribution of the larvaceanOikopleura dioicain a North Patagonian tidal frontal system (42°–45°S) of the SW Atlantic Ocean

Mariela L. Spinelli, Carla Derisio, Patricia Martos, Marcelo Pájaro et autres

In frontal systems, larvaceans generally comprise a significant fraction of the mesozooplankton. Given the low mobility of these organisms, their vertical distribution is directly influenced by the physical conditions of the water column. The main goal of this study was to investigate …
