| omura's whales (balaenoptera omurai) off northwest madagascar: ecology, behaviour and conservation needs. | the omura's whale (balaenoptera omurai) was described as a new species in 2003 and then soon after as an ancient lineage basal to a bryde's/sei whale clade. currently known only from whaling and stranding specimens primarily from the western pacific and eastern indian oceans, there exist no confirmed field observations or ecological/behavioural data. here we present, to our knowledge, the first genetically confirmed documentation of living omura's whales including descriptions of basic ecology a ... | 2015 | 26587244 |
| balaenoptera omurai is a newly discovered baleen whale that represents an ancient evolutionary lineage. | balaenoptera omurai, formerly classified as a small form of bryde's whale, was recently reclassified as a new baleen whale species of the family balaenopteridae. although researchers have investigated the evolutionary history of balaenopteridae and their relatives using molecular phylogenetic methods, the taxonomy of the ordinary bryde's whale (balaenoptera brydei) and small-form bryde's whales (balaenoptera edeni and b. omurai) remains unclear. we have used complete mtdna sequences and short in ... | 2006 | 16843687 |
| investigation of trophic level and niche partitioning of 7 cetacean species by stable isotopes, and cadmium and arsenic tissue concentrations in the western pacific ocean. | a total of 24 stranded or bycatch cetaceans, including balaenoptera omurai, lagenodelphis hosei, kogia sima, stenella attenuata, grampus griseus, neophocaena phocaenoides, and sousa chinensis, were collected from 2001 to 2011 in taiwan. using the muscular δ(13)c and δ(15)n data, three ecological groups were identified as the oceanic baleen whale, the neritic, and the coastal toothed whale groups, coinciding with their taxonomy, feeding habits and geographical distribution. a horizontal inshore t ... | 2015 | 25684592 |
