Social associations and habitat selection delineate two subpopulations of west coast transient killer whales (Orcinus orca rectipinnus) in the California Current System Open
West coast transient (mammal-eating) killer whales ( Orcinus orca rectipinnus ) inhabit the California Current off the west coast of North America from southern British Columbia, Canada to southern California, United States. Although genet…

Capture–recapture estimates of Antarctic blue whale abundance and population growth rate Open
Photo‐identifications of Antarctic blue whales ( Balaenoptera musculus intermedia ) collected from 2003/2004 to 2018/2019 were used in a capture–recapture analysis to estimate abundance and population growth rate for the circumpolar Antarc…

Using Antarctic blue whale photo-ID data from the SOWER cruises: Capture-recapture estimates of abundance Open
Photographs of Antarctic blue whales were collected as part of the IWC’s SOWER cruises from 1987/88 to 2008/09. Photo‐ID data from 15 cruises were used in a pilot study that conducted capture‐recapture analysis to produce estimates of supe…

Photo‐identification and satellite telemetry connect southern right whales from South Georgia Island (Islas Georgias del Sur) with multiple feeding and calving grounds in the southwest Atlantic Open
The sub‐Antarctic waters of South Georgia Island (Islas Georgias del Sur, SG/IG) are a regularly visited feeding ground for southern right whales ( Eubalaena australis , SRW) in the southwest Atlantic. Satellite telemetry and photo‐identif…

Observations of southern right whales (<i>Eubalaena australis</i>) surface feeding on krill in austral winter at South Georgia Open
Southern right whales (Eubalaena australis) occur in the waters around the sub-Antarctic island of South Georgia, where they use the area to feed during the austral summer months (Jackson et al., 2020; Kennedy et al., 2020; Moore et al., 1…

The spectacled porpoise (Phocoena dioptrica) in Antarctic waters Open
Most knowledge on the biology and ecology of the spectacled porpoise (Phocoena dioptrica) has been obtained from stranded specimens, with less than fifteen confirmed sightings in the sea. Published photographs of live animals in their natu…

Observations of killer whales off East Antarctica, 82°-95°E, in 2009 Open
Observations of killer whales (Orcinus orca) during a survey off East Antarctica, 82°–95°E revealed previously undescribed variations in pigmentation and group associations. During the survey 24 killer whale groups were sighted south of 60…

Surfacing rates, swim speeds, and patterns of movement of Antarctic blue whales Open
During three surveys in the austral summers of 2013, 2015, 2019, data on Antarctic blue whale blow rates, dive times, swim speeds, and broadscale movements were collected using video photogrammetric tracking and intra-voyage photo-identifi…

More vaquita porpoises survive than expected Open
In 2018, it was estimated that fewer than 20 of Mexico’s endemic vaquita porpoise Phocoena sinus remained, and the species was declining by 47% yr -1 . Entanglement in gillnets is the sole threat to the species, and since the last populati…
