Many aspects of blue whale biology are poorly understood. Some of the gaps in our knowledge, such as those regarding their basic taxonomy and seasonal movements, directly affect our ability to monitor and manage blue whale populations. As a step towards filling in some of these gaps, microsatellite and mtDNA sequence analyses were conducted on blue whale samples from the Southern Hemisphere, the eastern tropical Pacific (ETP) and the northeast Pacific. The results indicate that the ETP is… Expand
Allometry and morphometry of blue whales photographed in the Gulf of California: insights into subspecies taxonomy in the Eastern North Pacific
The Eastern North Pacific (ENP) blue whale population is considered the most recovered worldwide. Despite this, its subspecies taxonomy is yet to be resolved. A previous morphological analysis usingExpand
Isotope-based inferences of the seasonal foraging and migratory strategies of blue whales in the eastern Pacific Ocean.
Isotope data revealed that whales in the southern Eastern Tropical Pacific generally do not forage in the northeast Pacific, which suggests a north-south population structure with a boundary near the equator. Expand
From Chilean Patagonia to Galapagos, Ecuador: novel insights on blue whale migratory pathways along the Eastern South Pacific
The results suggest special efforts should be put forward to identify blue whale critical areas and understand key behavioral aspects in order to provide the basis for their conservation on a regional context (i.e., reducing potential ship strike and promote Marine Protected Area (MPA) implementation in Chile, Ecuador and Peru). Expand
Body size data collected non-invasively from drone images indicate a morphologically distinct Chilean blue whale (Balaenoptera musculus) taxon
The Chilean whale is found to be morphologically intermediate in both overall body length and relative tail length, thereby joining other diverse data in supporting the Chilean blue whale as a unique subspecific taxon. Expand
Revision of fin whale Balaenoptera physalus (Linnaeus, 1758) subspecies using genetics
Three subspecies of fin whales (Balaenoptera physalus) are currently recognized, including the northern fin whale (B. p. physalus), the southern fin whale (B. p. quoyi), and the pygmy fin whale (B.Expand
Broad-scale study of the seasonal and geographic occurrence of blue and fin whales in the Southern Indian Ocean
The results confirm the importance of the southern Indian Ocean for several populations of endangered large whales and present the first long-term assessment of fin whales in theSouthern Indian Ocean. Expand
Documentation of a New Zealand blue whale population based on multiple lines of evidence
Species conservation depends on robust population assessment. Data on population abundance, distribution, and connectivity are critical for effective management, especially as baseline informationExpand
Whole-genome sequencing of the blue whale and other rorquals finds signatures for introgressive gene flow
The genomes of six whales are presented, including the blue whale (Balaenoptera musculus), to reconstruct a species tree of baleen whales and to identify phylogenetic conflicts, raising questions about how genetic divergence can be established. Expand
Occurrence of blue whales (Balaenoptera musculus) in offshore waters of southeastern Brazil
At-sea sightings of blue whales, Balaenoptera musculus, in Brazil are rare. A mother-calf pair was observed in deep (2645 m) waters off southeastern Brazil (22°11′S 038°58′W); during a seismic surveyExpand
Diel differences in blue whale (Balaenoptera musculus) dive behavior increase nighttime risk of ship strikes in northern Chilean Patagonia.
The association to diurnal prey migration and shallow nighttime dive behavior, suggests that blue whales are at increased risk of ship collisions during periods of darkness since the estimated maximum ship draft of vessels operating in the region is also ∼ 12 m. Expand


Blue whale population structure along the eastern South Pacific Ocean: evidence of more than one population
The results suggest at least two breeding population units or subspecies exist, which is supported by other lines of evidence such as morphometrics and acoustics and supports the hypothesis that eastern South Pacific blue whales are using the ETP area as a possible breeding area. Expand
The distribution of blue whales, Balaenoptera musculus, in the eastern tropical Pacific (ETP) was analyzed from 211 sightings of 355 whales recorded during research vessel sighting surveys or byExpand
Past and present distribution, densities and movements of blue whales Balaenoptera musculus in the Southern Hemisphere and northern Indian Ocean
Blue whales avoid the oligotrophic central gyres of the Indian, Pacific and Atlantic Oceans, but are more common where phytoplankton densities are high, and where there are dynamic oceanographic processes like upwelling and frontal meandering. Expand
High genetic diversity in a small population: the case of Chilean blue whales
Although levels of genetic diversity are frequently used as estimators of population health, these parameters depend on the biology of the species and should be taken into account in a monitoring framework study to obtain a more complete picture of the conservation status of a population. Expand
Insights into the population structure of blue whales in the Eastern North Pacific from recent sightings and photographic identification
Blue whales were widely distributed in the North Pacific prior to the primary period of modern commercial whaling in the early 1900s. Despite concentrations of blue whale catches off British ColumbiaExpand
Reproductive parameters of eastern North Pacific blue whales Balaenoptera musculus
It is reported here that females show site fidelity to the Gulf of California (GoC) even when not lactating, suggesting the existence of additional calv- ing and nursing grounds for this population. Expand
Discovery of a blue whale feeding and nursing ground in southern Chile
The recent discovery of, arguably, the most important blue whale feeding and nursing ground known to date in the Southern Hemisphere, which is located near the fjords off southern Chile is reported. Expand
The satellite-acquired locations of 10 blue whales (Balaenoptera musculus) tagged off southern California with Argos radio tags were used to identify (1) their movements during the late summerExpand
A new song recorded from blue whales in the Corcovado Gulf, Southern Chile, and an acoustic link to the Eastern Tropical Pacific
The identity, distribution and movements of blue whales Balaenoptera musculus that forage in the Chiloense Ecoregion in Southern Chile remain unclear. Studies of blue whale songs have identifiedExpand
Low genetic diversity in pygmy blue whales is due to climate-induced diversification rather than anthropogenic impacts
Low levels of genetic diversity in Australia are due to a natural founder event from Antarctic blue whales (Balaenoptera musculus intermedia) that occurred around the Last Glacial Maximum, followed by evolutionary divergence. Expand
