“…During the survey, some whales were observed making repeated dives of > 9 min duration. Their target prey were most likely to be krill or copepods, based on previous studies (Matthews 1938, Valenzuela et al 2009, 2018 and the current isotope data. Similarly long dive profiles of ~10 min duration and 50 m depth have also been recorded in Argentine Patagonia (Argüelles et al 2016); in that case it was suggested that those whales were feeding on lobster krill (the Grimothea post-larvae of Munida gregaria), consistent with previous observations by Matthews (1932).…”

“…These photo-ID studies began in Península Valdés, Argentina, in the 1970s and in Brazil in the 1980s (Payne 1986, Groch et al 2005. The summer foraging destinations of whales wintering in Península Valdés have been investigated using photo-ID, stable isotope and satellite telemetry data, and directly link this calving ground to South Georgia (Best et al 1993, Moore et al 1999, Rowntree et al 2001, Valenzuela et al 2009, 2018, Zerbini et al 2018. The stable isotope work led to the hypothesis that whales in the southwest Atlantic use 2 primary offshore feeding strategies during summer: one where they feed on copepods in lower latitude waters of the South Atlantic, including the Patagonian shelf, and another where they feed on Antarctic krill in the high latitudes of the South Atlantic, including South Georgia, the Scotia Arc and the South Sandwich Islands (Valenzuela et al 2009(Valenzuela et al , 2018.…”

“…Standard density-dependent population theory, exemplified by logistic growth models (Tsoularis and Wallace, 2002), holds that populations reduced to low densities should in the absence of migration increase at close to the maximum biological rate.

“…While there have been ten ship-strikes with at least four mortalities and 28 entanglements with two deaths in Australian waters, the fatalities include mother and calf pairs from the small, remnant southeast population (Kemper et al, 2008;Carroll et al, 2015;Lanyon and Janetzki, 2016;Peel et al, 2018;Tulloch et al, unpublished). Vessel strikes to the Brazilian population still occur at low levels (<0.5 per year) but between 1999 and 2014, 38 entanglement cases were reported (Figueiredo et al, 2017;Groch, 2018). In Argentina, 6% of whales identified in 2007,2008,2009 seasons in Golfo Nuevo showed evidence of vessel interactions via scarring (International Whaling Commission [IWC], 2011).…”
