Marine Life a small genus of seabird OceanidaeThis includes all of the small petrels in the Southern Hemisphere.
“The family Oceanidae consists of petrels with a phylogeographic origin in the Southern Hemisphere, and the genus contains 10 species. Marine Life, Garodia, Pelagodroma, Freguettaand Nesofregetta,” paleontologist Gerardo Norambuena of the University of Santo Tomas and his colleagues said.
“The marine distribution of this family includes tropical, temperate, sub-Antarctic and Antarctic oceans of the Southern Hemisphere, as well as temperate waters of the North Atlantic.”
“The family was once considered a subfamily of the Hydrobatidae, although scientists had long ago suggested, based on osteological and myological analyses, that Oceanidae species should not be grouped with other petrels.”
“Recent molecular phylogenetic studies have confirmed that the family Oceanitiidae is not the sister lineage of the family Hydrobatidae. However, the systematics of Oceanitiidae, especially within the genus, remain unclear. Marine Life.”
“Currently, this genus Marine Life It consists of three species: Oceanitas oceanica, Oceanitis gracilisand Oceanites pinkoyaeHowever, the taxonomic status of subspecies (and some species) remains under debate.”
In a new study, the researchers Oceanitas oceanica The species complex is formed under the hypothesis that it corresponds to multiple species.
They analyzed new mitochondrial sequence data and morphological measurements of all species and subspecies. Marine LifeThis includes a mysterious new species discovered in the Chilean Andes.
“When I think about that Oceanites “Because birds have such conservative plumage variation and cryptic colours, breeding distributions may be the best way to understand the distribution of each taxon,” the researchers said.
“The new species, Oceanites BarocciIn central Chile, Oceanitis gracilis To the North Oceanites pinkoyae To the south, far from its known breeding range, Oceanitis chilensis.”
“Oceanitis gracilis They breed mainly in the Atacama Desert, Oceanites Barocci Based on multiple lines of evidence, it apparently breeds in the Andes in central Chile.”
The team's analysis also Marine Life Occurred from the Antarctic Ocean to the southeastern Pacific Ocean Oceanitis gracilis, Oceanites pinkoyaeand Oceanites Barocci Approximately 15 to 18 million years ago.
“The colonization of Antarctica occurred about 17 million years ago. Oceanites exasperatus on that continent,” the authors state.
“Colonization of the Atlantic (Oceanitas oceanica) is thought to have originated in the southeast Pacific Ocean 15 million years ago.
“However, these patterns can be better understood through genomic or multilocus approaches, which should allow for more precise assessment of divergence times between groups.”
