| The Strobel Plateau is a conspicuous and representative basaltic plateau ("meseta") in the Patagonian steppe, Argentina. This plateau is dotted with more than 1500 shallow lakes, which are regularly used by waterbirds and support one of the main breeding populations of the near threatened Hooded Grebe (Podiceps gallardoi). We collected data on bird presence and abundance in 41 shallow lakes, covering a wide spectrum of the wetland environmental variability found in the area. We conducted six surveys from spring to fall between 2004 and 2006. We recorded a total of 18 waterbird species, which represent 5 different families. Anatidae was the family most represented with 12 species, accounting for 85% of the observed waterbirds. Waterbird distribution among... |

| El conocimiento sobre la distribución reproductiva y la abundancia de aves marinas es clave para su manejo y conservación. Se presenta información sobre la reproducción de gaviotas y gaviotines entre 2006-2013 en la Reserva Natural de Usos Múltiples Bahía San Blas, provincia de Buenos Aires. Se registró la reproducción de ocho especies, en la mayoría de los casos en colonias mixtas. Durante 2013 se contabilizaron 3635 nidos de Gaviota Cocinera (Larus dominicanus) distribuidos en 4 colonias, 359 nidos de Gaviota Cangrejera (Larus atlanticus) en 2 colonias, 6 nidos de Gaviota Capucho Café (Larus maculipennis), 841 nidos de Gaviotín Real (Thalasseus maximus), 195 nidos de Gaviotín Pico Amarillo (Thalasseus sandvicensis), 265 nidos de Gaviotín Lagunero (Sterna... |

| 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... |

| Estudiamos la biología reproductiva de los cormoranes Imperial (Phalacrocorax atriceps) y Cuello Negro (Phalacrocorax magellanicus) en el Golfo San Jorge, Argentina, durante las temporadas reproductivas de 1991-1993. Los fechas en que fueron observados los primeros huevos variaron entre años, siendo entre mediados de octubre y mediados de noviembre para el Cormorán Imperial, y entre fines de octubre y principio de diciembre para el Cormorán Cuello Negro. Durante 1993, el 87% y el 86% de las parejas de Cormorán Imperial y Cormorán Cuello Negro, respectivamente, completaron su nidada en las cuatro semanas siguientes al inicio de la puesta. Para ambas especies, el número de huevos por nido al mes de iniciada la puesta presentó diferencias significativas entre... |

| The Argentine coastal zone, with its highly productive coastal waters, allows the existence of important seabird and marine mammal breeding assemblages, fish and crustacean spawning and nursery areas, and extensive macroalgae and mollusk beds. Knowledge of factors determining the dynamics of coastal waters is urgently needed to help understand their influence on biological processes and marine biodiversity. Available information in the region is currently scarce due to the low number of oceanographic cruises and oceanographic modeling studies. We evaluate the capacity of high-resolution satellite information for the identification and analysis of coastal processes such as fronts, upwellings, and small scale eddies. Using two case studies, we show how the... |
