The southwestern Atlantic southern right whale, Eubalaena australis, population is growing but at a decelerated rate
(Wiley Blackwell Publishing, Inc, 2018-04)
This paper reports on aerial surveys conducted to estimate the relative abundance and trend in growth of the southern right whale (Eubalaena australis) population from Península Valdés. The number of whales counted tripled ...
Diving behavior of southern right whales (Eubalaena australis) in a maritime traffic area in Patagonia, Argentina
(European Association for Aquatic Mammals, 2016-02)
First molecular estimate of sex-ratio of southern right whale calves, Eubalaena australis, for Brazilian waters
(CAMBRIDGE UNIV PRESS, 2009)
The southern right whale (Eubalaena australis) was one of the most intensively hunted whales between the 17th and 20th centuries in the southern hemisphere. Recent estimates indicate that today there are around 7000 whales, ...
Erysipelothrix rhusiopathiae isolated from gullinflicted wounds in southern right whale calves
(Inter-Research, 2016-08)
Southern right whales Eubalaena australis from Peninsula Valdés, Argentina, show wounds produced by kelp gulls Larus dominicanus that feed on the whales’ dorsal skin and blubber. During the 2013 whale season, several calves ...
Nonreproductive sexual behavior in baleen whales: Sexual harassment by an adult male on a calf in southern right whales (eubalaena australis)
(The European Association for Aquatic Mammals, 2017-02)
We describe a sexual harassment by an adult male southern right whale to a conspecific calf while on the calving and mating grounds near PV. Sexual harassment is defined in this paper as the behavior of an adult male ...
Density-dependent changes in the distribution of Southern Right Whales (Eubalaena australis) in the breeding ground Peninsula Valdés
(PeerJ, 2018-12)
Background: The Southern Right Whale (Eubalaena australis) population of the South–western Atlantic Ocean is recovering. In the breeding ground of Peninsula Valdés, as a consequence of the population growth, expansion to ...
Identification, molecular and phylogenetic analysis of poxvirus in skin lesions of southern right whale
(Inter-Research, 2015-10)
Poxvirus skin disease has been reported in several species of cetaceans, principally in odontocetes, and a single report in mysticetes. Southern right whales Eubalaena australis in Peninsula Valdes, Argentina, show a variety ...
Southern right whales generally appear not to react to transiting research vessels

Reactions of southern right whales (SRWs) related to whale-watching boats have been reported in Patagonia, but there are no quantitative data showing how these whales react to boats not preforming whale-watching trips. The ...
Demand-driven commercial whalewatching in Península Valdés (Patagonia): conservation implications for right whales
(Cambridge. International Whaling Commission, 2001-12)
One of the largest remaining populations of the southern right whale, Eubalaena australis, breeds along the coast of Península Valdés, in Argentine Patagonia. The area offers excellent opportunities for whalewatching because ...
Stable isotopes (δ15N, δ13C, δ34S) in skin reveal diverse food sources used by Southern right whales Eubalaena australis
(Inter-Research, 2018-09)
Skin samples collected from living Southern right whales (SRWs) off Península Valdés, Argentina, show a wide range of stable isotope values (δ15N, δ13C, δ34S). These were compared to the isotopic signatures of euphausiids ...
