NANYUKI Air Jordan 1 Retro High OG Storm Blue White Blue Cheap , Kenya, April 19 (Xinhua) -- In central Kenya's Ol Pejeta Conservancy, Sudan lies quietly in his pen, alone and lonely. Outside, there is a team of armed rangers who take turns guarding the mammal day and night.

Sudan is the last male of five remaining known northern white rhinos in the world.

United States and Czech Republic.

At 42, Sudan is too old to mate as the mammal usually has a life expectancy of 40 years in wild, and maybe a little longer in captivity. The rest four females are also barely to reproduce either because of old age or other physical reasons.

"It's highly unlikely that the animal will not go extinct," said Richard Vigne, Ol Pejeta's chief executive. "If a species diminishes to such small number Air Jordan 1 Retro High OG Black White Wholesale Jordan , then it becomes very difficult to recover that species."

Vigne said there were several natural breeding attempts when the animals were first brought to the conservancy, but all failed.

"The animals haven't lived in a natural environment for a long time, and they are getting old and inter-related," said Vigne, adding that if the rhinos haven't bred for a long time, it would not be easy for them to start again as their reproductive organs may start to degenerate.

Mohammed Doyo, the keeper of the rare species, also recalled he saw Sudan try to mate three years ago with a female southern white rhino, yet it eventually turned out futile.

Like the northern white rhino Mens Air Jordan 1 Retro High OG Yin Yang White Black Cheap Jordan Shoes , a southern white one is a subspecies closely related to the northern, but is less endangered. It has an estimated population of 20,000 worldwide, mostly in South Africa.

Both subspecies has wide month though the northern has hair along the edge of its ears. Moreover, the northern tends to be slightly less social than the southern, and prefers thicker bush while the southern likes to be in open space.

ARTIFICIAL REPRODUCTION METHODS DIM

In this 90,000 acre of conservancy, instead of wandering around on the vast savanna as before, Sudan now has been kept in enclosure for a year to avoid hurt from other rhinos Cheap Air Jordan 1 High OG Mens , according to Doyo. Though guarded by armed rangers around the clock, the mammal's horns had also been trimmed for fear of poaching.

"He is like my own children. I would feel very sad if we lose it," said Doyo.

"Sudan could die tomorrow," said Vigne, noting that the last hope to save the rare species from complete distinction would be artificial reproduction methods.

One way is vitro fertilization: take eggs and sperms of northern white rhinos and create an embryo, which is then implanted into a female southern white rhino, hoping to get a northern white calf.

"However, this technology has never been done in rhinos before, and it is very expensive Air Jordan 1 Retro High OG Mens ," said Vigne, adding that they would first develop the technique on southern white rhinos, and apply it on the northern white rhinos once there is enough money and the technique gets perfected.

"We need to raise money first, and we estimate it would take as long as two years before we can get a successful pregnancy with a pure northern rhino embryo," he said.

There is also another option, which will use some already stored semen of northern white rhinos in the world and crossbreed it with female southern white rhinos to get a hybrid. However, this means, if succeeds, it would not be a pure northern white rhino.

"It is not perfect Air Jordan 1 High OG Mens For Sale , but it is better than nothing," Vigne lamented, calling on more efforts to save the rare rhino and other endangered wildlife.

"Poaching of rhinos across Africa still continues at a very high rate. If we as human race don't do something to stop it, what is happening now to the northern white rhino will happen to many other species," he said.

NAIROBI, April 30 (Xinhua) -- World 5,000m silver medalist Mercy Cherono of Kenya will skip the Shanghai Diamond League meeting on May 17.

Cherono, who won gold at the 2014 Commonwealth Games in Glasgow, will be missing her second competition in China Air Jordan 1 High OG Mens Shoes , after failing to make the team to the World Cross Country Championships in Guiyang in March.

"I know winning World Championships is not easy, but I will try my best to come home with a medal. I did well in my junior races and I have to extend the same in my senior ranks," said Jebet.

The IAAF Diamond League encompasses 32 individual event disciplines, with a points scoring "Diamond Race" which runs throughout the 14 meeting series.
