Ocurrencia De Focas (Mammalia, Carnivora, Phocidae) en Uruguay

Abstract

RESUMENSe presenta una revisión actualizada sobre la ocurrencia de fócidos para Uruguay (1921Uruguay ( -2016. Se obtuvieron 64 registros que ocurrieron en la costa Atlántica (n=45), Río de la Plata (n=13) y en otros ríos y arroyos (n=6). Se reclasificaron especímenes erróneamente identificados, además se encontraron especímenes perdidos y se presentan 21 registros de fócidos no publicados.Palabas clave: Focas, Phocidae, Registros, Uruguay ABSTRACTOccurrence of seals (Mammalia, Carnivora, Phocidae) in Uruguay. An updated review on the occurrence of seals for Uruguay (1921Uruguay ( -2016 is presented. A total of 64 records occurred on the Atlantic coast (n=45), Rio de la Plata (n=13) and other rivers and streams (n=6). Erroneously identified specimens were reclassified, missing specimens were found and 21 unpublished seals records are presented.

“…La foca leopardo es una especie solitaria y pagofílica que se dispersa ampliamente en bajas densidades a lo largo de la plataforma de hielo (Rogers, 2009), y algunos individuos se desplazan hasta zonas subantárticas. Los avistamientos oportunistas de focas leopardo fuera de su rango primario han ocurrido en Argentina (Castello y Rumboll, 1978;Rodríguez et al, 2003;Daneri et al, 2011), Brasil (Pinedo, 1990;Rosas et al, 1992;Ferreira et al, 1995;Silva, 2004;Moura et al, 2011), Chile (Hückstädt, 2015;Acevedo et al, 2017), Uruguay (Juri, 2017), Sudáfrica (Best, 1971;Vinding et al, 2013;Hückstädt, 2015;datos no The leopard seal (Hydrurga leptonyx) is an Antarctic pinniped with a wide circumpolar distribution that includes both Antarctic and Subantarctic waters (Bester et al, 2002;Rodríguez et al, 2003;Hückstädt, 2015;Rogers, 2018) (see Figure 1). The leopard seal is a solitary and pagophilic species that disperses widely at low densities along the ice shelf (Rogers, 2009), and some individuals move to Subantarctic zones.…”

Sighting of a Southern elephant seal <i>Mirounga leonina</i> in the Toltén River, southern Chile

“…Major breeding colonies are located in South Georgia Island, Kerguelen and Heard Islands, Macquarie Islands and Peninsula Valdés (Boyd et al 1996, Lewis et al 1998, Guinet et al 1999, Slip & Burton 1999, McMahon et al 2005. Vagrant individuals have been occasionally recorded north of the Antarctic circumpolar zone (Oosthuizen et al 1988, Alava & Carvajal 2005, Lewis et al 2006, Oliveira et al 2011, Shaughnessy et al 2012, Bublichenko 2015, Mayorga et al 2015, Juri 2017). In the case of continental Chile, three breeding colonies are located south of 51°S in the Magallanes Region: width of 300 m, a depth of 1.5 to 12 m, and a homogeneous temperature of around 13.7 ºC (Gomez-Uchida et al 2016).…”
