The hourglass dolphin, Lagenorhynchus cruciger, is one of the smallest cetaceans found in Antarctic waters. Although frequently observed, this is one of the least studied species of dolphin. In this study, we investigate the occurrence of hourglass dolphin in the South-West Atlantic and Southern Ocean from 42°S to 63°S and characterize the oceanographic and environmental features associated with their occurrence. Sighting data were collected during two scientific cruises in December 2009 and… 
First sighting of a live hourglass dolphin (Lagenorhynchus cruciger) in inland waters of southern Chile
Although the animal sighted is more likely a vagrant than a migrant to inland waters of southern Chile, it is even more uncertain what biological and/or physical properties were determinants in the movements of hourglass dolphin.
Spatial Models of Abundance and Habitat Preferences of Commerson’s and Peale’s Dolphin in Southern Patagonian Waters
This work provides the first large-scale abundance estimate for Peale's dolphin in the Atlantic Ocean and an update of population size for Commerson’s dolphin, and contributes to baseline data on suitable habitat conditions for both species in southern Patagonia, which is essential for the implementation of adequate conservation measures.
A major autumn feeding ground for fin whales, southern fulmars and grey-headed albatrosses around the South Shetland Islands, Antarctica
Seabirds and marine mammals were recorded during an autumn expedition of icebreaking RV Polarstern between Punta Arenas and the South Shetland Islands, Antarctica in March/ April 2012 and it is suggested that the area deserves future biological studies, especially in autumn, and a special protection management.
Summer distribution of marine mammals encountered along transects between South Africa and Antarctica during 2007-2012 in relation to oceanographic features
The at-sea summertime distribution of marine mammals between South Africa and Antarctica was determined along eight transects surveyed between December 2007 and January 2012. During 1930 30-minute
Can habitat characteristics shape vertebral morphology in dolphins? An example of two phylogenetically related species from southern South America
Although the Peale's dolphin and the hourglass dolphin are closely related phylogenetically, vertebral morphology is influenced by a diverse set of ecological and behavioral factors, reflecting a high degree of vertebral plasticity within the genus.
Habitat Partitioning in Sympatric Delphinids Around the Falkland Islands: Predicting Distributions Based on a Limited Data Set
Spatial modelling based on line transect data is a standard method for characterising marine mammal distributions and habitat preference. However, collecting the data required is costly and may be
Evaluating the isotopic niche of beaked whales from the southwestern South Atlantic and Southern Oceans
This poster presents a probabilistic procedure for estimating the intensity of the volcanic activity in Tierra del Fuego during the period of June 21 to 29, 1997 and its results can be compared to those of previous seasons.

We conducted 239.5 h and 3,494 km of cetacean surveys in the Amundsen and Bellingshausen seas, from 15 February to 31 March 1994; most of the area, the large portion of which was ice covered, had
Distribution of Delphinidae (Cetacea) in relation to sea surface temperatures off Eastern and Southern New Zealand
Summary Records of four species of Delphinidae, Delphinus delphis, Lissodelphis peroni, Lagenorhynchus obscurus, and Lagenorhynchus cruciger in waters to the east and south‐east of New Zealand are
The importance of the Patagonian Shelf for top predator species breeding at South Georgia
The Patagonian Shelf is, therefore, not only of global importance for the diversity and abundance of its resident top predators but is just as critical for the survival of many visiting species, some of which are even more endangered.
Overall, much more is known about odontocetes of the Southern Ocean now than in 1994 as a result of the establishment of a number of research programmes.
Southern Ocean environmental changes: effects on seabird, seal and whale populations
The main changes in the distribution and abundance of marine top predators in the Antarctic in the last two centuries were caused by an over-exploitation and certain taxa are especially vulnerable to at least some of the likely environmental changes.
Ecological importance of the Southern Boundary of the Antarctic Circumpolar Current
The association of primary production, Krill, and whales with the Southern Boundary, suggests that it provides predictably productive foraging for many species, and is of critical importance to the function of the Southern Ocean ecosystem.
Marine Biodiversity in the Atlantic and Pacific Coasts of South America: Knowledge and Gaps
This paper analyzes the status of knowledge of marine biodiversity in five subregions along the Atlantic and Pacific coasts of South America: the Tropical East Pacific, the Humboldt Current, the Patagonian Shelf, the Brazilian Shelves, and the Tropical West Atlantic, and it provides a review of ecosystem threats and regional marine conservation strategies.
