In an animal shelter, the Ol Pejeta Conservancy (Kenya), Sudan, the last male of northern white rhinoceros ( Ceratotherium simum cottoni), died . The fate of almost all species of rhinos is linked to the will of men: decades of persecution, fueled by fashions and silly superstitions of Chinese medicine, have caused the drastic reduction of many populations of these large herbivores. The other subspecies, the southern one (about 20, 000 individuals), lives in South Africa, Namibia, Zimbabwe, Kenya and Uganda.
Sudan, who was 45, was euthanized for his critical condition. It was part of a last, extreme attempt to save the subspecies, because together with the male two females were housed (protected day and night by the poachers): unfortunately, despite having been seen some mating, no small was born.
Blown away. The northern white rhinos lived in some areas of central Africa: Chad, Sudan, Uganda, Congo and the Central African Republic. The subspecies was particularly vulnerable, in particular due to the armed conflicts that affected the region for decades.
However, the death of Sudan does not put an end to projects to safeguard subspecies, because in vitro fertilization can still be used to try to obtain embryos. According to the researchers, one could start from the seed of the dead male and from the eggs of the females still alive.
