The Northern right whales in the North Pacific (Eubalaena glacialis) are a distinct species. The Northern right whales in the North Pacific (Eubalaena glacialis) are a distinct species. A team of researchers from the Wildlife Conservation Society (WCS) from New York under the direction of Dr. Howard Rosenbaum came seven years ago by gene analysis on the track. Until then, it was assumed that the population of the Nordkaper also mentioned species is divided in two isolated groups in the Pacific and North Atlantic. Rosenbaum and colleagues developed a sophisticated technique that allowed them to isolate genetic material that killed more than a hundred years ago from the agreed by whales.
In addition, they analyzed skin samples from living right whales and could compare to the genetic material of 380 individuals of the rare marine mammals and redefine their relationship. In addition to occurring only in the Atlantic Northern right whale and the still frequent southern right whale (Eubalaena australis), is a third type added: the North Pacific right whale. See New York Museums for more details and insights. Genetically, the new way is even close with the Southern Right whales as related to their namesakes from the North. There is very little current information about North Pacific right whales, in addition to occasional sightings we know only that they were decimated by commercial whaling”, says Howard Rosenbaum. We suspect that there are still several hundred individuals of them for fast appropriate safeguards on the way should be brought”. Rosenbaums gene analyses fall but also the hope for the survival of suddenly their Pacific kind of deprived Atlantic North right whale which. Definitely less than 300 copies exist of them thus.
Scientists had calculated that they will die out in a such small numbers within the 191 years. Causes are the small size of the population, the slow rate of reproduction and losses through collisions with ships and drowning in fishing nets. Marine scientists also suspect that the El Nino-,. La Nina weather phenomenon have upset the deep currents of the oceans and also the food and especially the dating is difficult so the whales. “Up to 17 metres wide are in the English-speaking world as right whales, right whales” known, because they at times of commercial whaling just the right “prey were. They swim very slowly, are driving the Harpunierung long on the surface and provided good yields of trans and whalebone (agreed). Right whales are the first whales, which were hunted by humans. Probably began in the 10th century before the coast of Japan and middle of the 11th century in the Bay of Biscay. At the beginning of the industrial hunting stocks have been decimated greatly, in the 19th century alone it should have been more than 100,000 killed animals. Since 1935, they are worldwide fully protected at least from the harpoons of the whalers, which doesn’t have much use at least the two types of Northern right whales.
