Description

Database with number of individuals and distribution of the southern elephant seals (Mirounga leonina) of Península Valdés, Argentina,breeding colony. Censuses on foot of the entire colony were carried out during the peak of the breeding season (October 3-7) when most of the population is ashore. All the breeding groups were counted and located. Demographic data also encompass reports of solitary individuals along the Atlantic and Pacific coasts of South America and offshore islands. Dispersion from 1990 to 2006 was obtained from surveying scientists and opportunistic sightings of naturalists, rangers and fishermen. Previous information was assessed with published records. – ESPAÑOL – Distribución en la costa y lugares de reproducción del elefante marino del sur en Sudamérica. Base de datos con número de individuos y distribución del elefante marino del sur (Mirounga leonina) en la colonia reproductiva de Península Valdés, Argentina. Los registros corresponden a relevamientos terrestres de toda la colonia llevados a cabo durante el pico de la temporada reproductiva (3-7 de Octubre), cuando la mayoría de los animales se encuentran en la costa. Todos los grupos de reproducción fueron contados y georeferenciados. Los datos demográficos se complementan con registros de animales solitarios observados en la costa e islas del Atlántico y Pacífico en Sudamérica. Los registros de dispersión se obtuvieron entre 1990 a 2006 a partir de observaciones oportunistas de científicos, naturalistas, guarda-faunas y pescadores. La información previa fue integrada a partir de registros publicados.

Sampling Description

Study Extent

–

Sampling

Censuses on foot of the entire colony of Península Valdés during the peak of the breeding season (October 3-7). Reports of solitary individuals along the Atlantic and Pacific coasts of South America and offshore islands. Platform: COASTAL STATIONS; FIELD SURVEYS; GROUND-BASED OBSERVATIONS. Instrument: Cameras; GPS; BINOCULAR.

Quality Control

Historic references of individuals located along South America coast and offshore islands are opportunistic sightings. When the position ashore was not reported it was estimated from digitalized maps. Positioned groups during the breeding season are highly accurate, and belong to long term research on southern elephant seals in Patagonia.
