A new study by researchers has claimed that Chinas desire to promote eco-tourism is leading to the deaths of Tibetan monkeys in their infancy in the Mount Huangshan Scenic Area of the countrys Anhui Province.
According to National Geographic, the skyrocketing infant mortality of Tibetan macaques is being precipitated by them being confined to a restricted range and regularly competing for corn thrown by excited spectators.
The study claims that this scenario has triggered adult aggression toward each other and toward their young, and as a result, less than half of the infants survive into adulthood.
"I think a lot more work needs to be done on how eco-tourism impacts the animals," said the studys co-author Carol Berman, an anthropologist at the State University of New York at Buffalo.
Results of the 19-year study will be published in the October edition of the International Journal of Primatology.
Berman's team studied the Tibetan macaques for six years before eco-tourism began in 1991.
They also collected data while tourists visited the animals between 1992 and 2004, including a span in 2003 when tourism was suspended.
Infant mortality was low prior to the advent of eco-tourism and was primarily caused by disease, the team found.
Although they didn't witness all the attacks, many of the infant corpses Berman's team found had bite wounds indicative of adult macaques.
