A newly discovered species of living baleen whale

  title={A newly discovered species of living baleen whale},
  author={Shiro Wada and Masayuki Oishi and Tadasu Yamada},
In the late 1970s eight Balaenoptera specimens of unknown identity were caught in the lower latitudinal Indo-Pacific waters by Japanese research whaling vessels. The combination of the allozyme patterns and physical maturity of the eight specimens separated them from all acknowledged Balaenoptera species. In September 1998 we collected a medium-sized baleen whale carcass on a coastal island in the Sea of Japan. This specimen and the previously collected eight specimens resembled Balaenoptera… 

Population differentiation of 2 forms of Bryde's whales in the Indian and Pacific Oceans.

A population-level analysis of mtDNA control region sequences with 56 new samples from Oman, Maldives, and Bangladesh, plus published sequences from off Java and the Northwest Pacific indicates strong differences in the genetic diversity and population structure within each Bryde's whale subspecies.

Omura’s whales (Balaenoptera omurai) off northwest Madagascar: ecology, behaviour and conservation needs

The results demonstrate that the Omura’s whale is a tropical whale without segregation of feeding and breeding habitat, and is probably non-migratory; the data extend the range of this poorly studied whale into the western Indian Ocean.

A new species of rorqual whale (Cetacea, Mysticeti, Balaenopteridae) from the Late Miocene of the Southern North Sea Basin and the role of the North Atlantic in the paleobiogeography of Archaebalaenoptera

From a North Atlantic center of origin, two dispersal events are inferred that led to the origins of Archaebalaenoptera species in the South Pacific and Mediterranean and the paleobiogeographic analysis suggests that the North Atlantic ocean played a major role as a centers of origin of a number of balaenopterid clades.

Phylogenetics of Baleen

The phylogenetic uncertainty appears to have originated from a rapid Miocene radiation of both Balaenopteridae and Neobalaenidae, which has resulted in incomplete sorting of genetic lineages and therefore conflicting genetic signals among nuclear and mitochondrial loci.

A new balaenopterid species from the Southern North Sea Basin informs about phylogeny and taxonomy of Burtinopsis and Protororqualus (Cetacea, Mysticeti, Balaenopteridae)

A new balaenopterid species from the Southern North Sea Basin informs about phylogeny and taxonomy of Burtinopsis and Protororqualus (Cetacea, Mysticeti, Balaenopteridae).

Phylogenetic relationships in southern African Bryde’s whales inferred from mitochondrial DNA: further support for subspecies delineation between the two allopatric populations

The data, combined with morphological and ecological evidence from previous studies, support subspecific classification of both South African forms under B. brydei and complete separation from B. edeni.

Genetic evidence reveals a unique lineage of Bryde’s whales in the northern Gulf of Mexico

The GOMx whales are as divergent as these subspecies and species are from each other, and the level of divergence suggests a unique evolutionary trajectory worthy of its own taxonomic standing.

Phylogenetics of Baleen Whales

Taxonomic relationships vary between studies, reconstruction methods and marker types, despite strong morphological support for the placement of Eschrichtiidae as a sister group to the Balaenopteridae, which appears to have originated from a rapid Miocene radiation of both families.

Middle Sized Balaenopterid Whale Specimens (Cetacea: Balaenopteridae) Preserved at Several Institutions in Taiwan, Thailand, and India

Light is shed to hitherto confused systematic understanding of so-called "Bryde's whales" by confirming four specimens of Bal- aenoptera acutorostrata and confirming nine of B. edeni, based on skele- tal morphology.

Population genetic structure of Bryde’s whales (Balaenoptera brydei) at the inter-oceanic and trans-equatorial levels

It is concluded that current gene flow between Bryde’s whale populations is low and that effective management actions should treat them as separate entities to ensure continued existence of the species.



Cetacean mitochondrial DNA control region: sequences of all extant baleen whales and two sperm whale species.

The findings suggest that the Antarctic minke whale should have a full species status, B. bonaerensis, and a close relationship between the gray whale (family Eschrichtiidae) sequence and those of the rorquals (family Balaenopteridae).

On a specimen of the rare fin whale, Balaenoptera Edeni Anderson, stranded on Pulu Sugi near Singapore

The stranding of the Pulu Sugi Whale offered a good opportunity to make a close comparison of edeni and brydei and if possible to clear up the relation between these two species.

Comparison between the complete mtDNA sequences of the blue and the fin whale, two species that can hybridize in nature

The mtDNA differences between the two whale species, involving both peptide coding and rRNA genes, suggest an evolutionary separation of ⩾5 million years and it is probable that the blue and fin whales are nearly as different in their mtDNA sequences as hybridizing mammal species may be.

The complete nucleotide sequence of the mitochondrial DNA of the fin whale,Balaenoptera physalus

A comparison between the cytochromeb gene of the fin whale and cy tochromeb sequences in the literature, including dolphin (Stenella) sequences, identified the cetaceans as monophyletic and the artiodactyls as their closest relatives.

Evolution of the cetacean mitochondrial D-loop region.

It is concluded that DNA slippage, in addition to point mutation, contributes to the evolution of the D-loop and that regions of conserved secondary structure in cetaceans and an ORF are unlikely to contribute significantly to the conservation of the central region.

Molecular and cell biology of marine mammals

Methods currently being used to explore marine mammal biology are discussed, such as genetic tracing of subpopulations of whales and seals by DNA fingerprinting, use of immune system molecular markers, cell culture and ELISA techniques, and electron microscopy.

The neighbor-joining method: a new method for reconstructing phylogenetic trees.

The neighbor-joining method and Sattath and Tversky's method are shown to be generally better than the other methods for reconstructing phylogenetic trees from evolutionary distance data.
