The composition of the cetacean community in the Falkland (Malvinas) Islands, southwest South Atlantic Ocean

An evaluation of the stranding record for the period 1866 to September 2012 confirms that the Falkland (Malvinas) Islands cetacean community is composed of 7 species of baleen whale, 7 beaked whale species, sperm whale, 8 species of dolphin and 1 of porpoise. The stranding record supports the specie...

description An evaluation of the stranding record for the period 1866 to September 2012 confirms that the Falkland (Malvinas) Islands cetacean community is composed of 7 species of baleen whale, 7 beaked whale species, sperm whale, 8 species of dolphin and 1 of porpoise. The stranding record supports the species composition based on at-sea surveys, but also confirms the presence of some rare, vessel-shy and/or offshore and deepwater species. Five species - long-finned pilot whale, Peale's dolphin, Commerson's dolphin, hourglass dolphin and sperm whale - are considered to have a regular presence in the Islands. Six species are considered infrequent, 11 are considered rare and 2 species had a historic presence but have not been recorded in recent years. The stranding record suggests potential temporal changes for some of these species, reflecting perhaps a recovery of their population from over-exploitation and/or changes in oceanographic conditions and/or prey availability. La evaluación de los registros de varamientos para las islas Falkland (Malvinas) desde 1866 y hasta septiembre 2012 confirma que la comunidad de cetáceos alrededor de esas islas está compuesta de 7 especies de ballenas, 7 ballenas picudas, el cachalote, 8 de delfines y 1 de marsopa. El registro de varamientos corresponde con la diversidad de especies a partir de observaciones en el mar, pero confirma también la presencia de algunas especies muy poco frecuentes, que no se acercan generalmente a embarcaciones y/o que corresponde a especies de aguas profundas. El calderón de aleta larga, el delfín austral, la tonina overa, el delfín cruzado y el cachalote son consideradas especies que tienen una presencia regular alrededor de las islas. Seis especies son consideradas escasas, 11 raras y se tiene registros históricos de 2 especies que, sin embargo, no han sido registradas en tiempos recientes. Los varamientos sugieren potenciales cambios temporales para algunas especies, reflejando posiblemente recuperaciones post-explotación, cambios en las condiciones ...
