Guest guest Posted August 18, 2005 Report Share Posted August 18, 2005 Elephants, lions to roam North America once more? Wed Aug 17, 1:03 PM ET LONDON (Reuters) - Scientists are proposing reintroducing large mammals such as elephants, lions, cheetahs and wild horses to North America to replace populations lost 13,000 years ago. The scientists say that not only could large tracts of North America act as breeding sanctuaries for species of large wild animals under threat in Africa and Asia, but that such ecological history parks could be major tourist attractions. "Africa and parts of Asia are now the only places where megafauna are relatively intact, and the loss of many of these species within this century seems likely," the team, led by Josh Donlan from New York's Cornell University, said. "Given this risk of further extinction, re-wilding of North American sites carries global conservation implications," the team wrote in Wednesday's issue of the science journal Nature. It said large mammals were common across all continents until the Late Pleistocene wipeout that hit North America hardest and handed the world to smaller species. The largest mammals in the United States today are bison. The Pleistocene epoch lasted from about 1.65 million years ago to 10,000 years ago. "Large carnivores and herbivores often play important roles in the maintenance of biodiversity, and thus many extinct mammals must have shaped the evolution of the species we know today," the scientists wrote. They said the pronghorn antelope's remarkable turn of speed must be due at least in part to the presence of the now extinct predatory American cheetah alongside it on North America's grasslands. Reintroducing the modern relatives of the Late Pleistocene losers to North America could spark fresh interest in conservation, contribute to biodiversity and begin to put right some of the wrongs caused by human activities. "Establishing Asian asses and Przewalski's horse in North America might help prevent the extinction of these endangered species and would restore equid species to their evolutionary homeland," the scientists wrote. They proposed a second phase that would include reintroducing African cheetahs, lions and Asian and African elephants to large private parks. "Free-roaming, managed cheetahs in the southwestern United States could save the fastest carnivore from extinction, restore what must have been strong interactions with pronghorn and facilitate ecotourism as an alternative for ranchers. "Managed elephant populations could similarly benefit ranchers through grassland maintenance and ecotourism," they wrote, adding that reintroducing lions would represent the pinnacle of the Pleistocene re-wilding of North America. They admitted the plan would be controversial but said it was a far better option than simply accepting the terminal decline of some of the world's most impressive species due to human encroachment and global warming. "Pleistocene re-wilding is an optimistic alternative," they wrote. "The obstacles are substantial and the risks are not trivial, but we can no longer accept a hands-off approach to wilderness preservation."

Guest guest Posted August 18, 2005 Report Share Posted August 18, 2005 Let's see if I have those correct. Scientists are sitting around spending money coming up with advise that we should "reintroduce" lions, elephants and cheetahs to an area that never had them. In the same breath they are saying "reintroduce large mammals . . . horses." I guess that they haven't come out of their little isolation labs long enough to realise that the "wild" horses are now being rounded up and killed for dog food? That would be compliments of that jibbering idiot in the white house! The jibbering idiot whose brother down in Florida is doing nothing to protect and save animals such as the Florida panther and the manatee! And these same science boobs are doing nothing to save habitat for species that are nearing extinction or are being hunted *legally* into extinction right now! Sheesh, why don't they fall in a test tube and drown!

Guest guest Posted August 19, 2005 Report Share Posted August 19, 2005 Hi Lynda, yesterday three dolfins where found dead on siesta beach near where I live. This month of august there have been a total of six dead dolfins and the month is not even over yet. The say it is due to red tide, a natural occurence, but environmentalist say different. manatees can be seen near a power plant, here in manatee county. I believe that manatees recognize individuals, because the same one keeps coming up to me and giving me kisses everytime I visit the rescue center. I know it's the same one because he/she is chubbier than the rest. - Lynda 8/18/2005 5:59:20 PM Re: reintroducing elephants, lions Let's see if I have those correct.
