A new study conducted by a student of University of California says that mountain lions run away from the sound of the humans
“We exposed pumas in the Santa Cruz mountains to the sound of human voices to see if they would react with fear and flee, and the results were striking: They were definitely afraid of humans”
The study might prove to be valuable because of the human interference in places of the habitat of the Pumas which increases the chance of human-puma encounters
Los Angeles, June 23, 2017:
One roar from the “King of the Jungle” and that will be enough to chill your spine. We all fear those canines and claw bearing wild cats but that might not be the only case. A new study conducted by a student of the University of California says that mountain lions run away to the sound of the humans.
Justine Smith, who led the study as a graduate student in University of California (UC), Santa Cruz in the US said, “We exposed pumas in the Santa Cruz mountains to the sound of human voices to see if they would react with fear and flee, and the results were striking: They were definitely afraid of humans.”
The study might prove to be valuable because of the human interference in places of the habitat of the Pumas which increases the chance of human-puma encounters.
“Fear is the mechanism behind an ecological cascade that goes from humans to pumas to increased puma predation on deer. We are seeing that human disturbance – beyond hunting – may alter the ecological role of large carnivores.” said Wilmers.
He also added, “As we encroach on lion habitat, our presence will likely affect the link between top predators and their prey,” he added.

California officials, having concluded coffee drinking is not a risky pastime, are proposing a regulation that will essentially tell consumers of America’s favorite beverage they can drink up without fear.
The unprecedented action Friday by the Office of Environmental Health Hazard Assessment to propose a regulation to clear coffee of the stigma that it could pose a toxic risk followed a review of more than 1,000 studies published this week by the World Health Organization that found inadequate evidence that coffee causes cancer.
The state agency implements a law passed by voters in 1986 that requires warnings of chemicals known to cause cancer and birth defects. One of those chemicals is acrylamide, which is found in many things and is a byproduct of coffee roasting and brewing present in every cup of joe.
Win for coffee industry
If the regulation is adopted, it would be a huge win for the coffee industry, which faces potentially massive civil penalties after recently losing an 8-year-old lawsuit in Los Angeles Superior Court that could require scary warnings on all coffee packaging sold in California.
Judge Elihu Berle found that Starbucks and other coffee roasters and retailers had failed to show that benefits from drinking coffee outweighed any cancer risks. He had previously ruled the companies hadn’t shown the threat from the chemical was insignificant.
The state’s action rejects that ruling.
“The proposed regulation would state that drinking coffee does not pose a significant cancer risk, despite the presence of chemicals created during the roasting and brewing process that are listed under Proposition 65 as known carcinogens,” the agency said in a statement. “The proposed regulation is based on extensive scientific evidence that drinking coffee has not been shown to increase the risk of cancer and may reduce the risk of some types of cancer.”
Attorney Raphael Metzger, who won the court case on behalf of The Council for Education and Research on Toxics, said he was shocked the agency would move to nullify the court decision and undermine its own report more than a decade ago that drinking even small amounts of coffee resulted in a significant cancer risk.
“The takeaway is that the state is proposing a rule contrary to its own scientific conclusion. That’s unprecedented and bad,” Metzger said. “The whole thing stinks to high hell.”
The National Coffee Association had no comment on the proposed change. In the past, the organization has said coffee has health benefits and that the lawsuit made a mockery of the state law intended to protect people from toxics.
Scientific evidence on coffee has gone back and forth over many years, but concerns have eased recently about possible dangers, with some studies finding health benefits.
Big Coffee didn’t deny that acrylamide was found in the coffee, but argued it was only found at low levels and was outweighed by other benefits such as antioxidants that reduce cancer risk.
The state agency’s action comes about a week after bipartisan bills were introduced in both houses of Congress to require science-based criteria for labels on food and other products. One of the sponsors, Rep. Kurt Schrader, D-Oregon, alluded to the California coffee lawsuit as an example of misleading warnings.
“When we have mandatory cancer warnings on a cup of coffee, something has gone seriously wrong with the process,” Schrader said in a news release. “We now have so many warnings unrelated to the actual health risk posed to consumers, that most people just ignore them.”
The lawsuit against Starbucks and 90 companies was brought by the tiny nonprofit under a law that allows private citizens, advocacy groups and attorneys to sue on behalf of the state and collect a portion of civil penalties for failure to provide warnings.
The Safe Drinking Water and Toxic Enforcement Act, better known as Proposition 65, requires warning labels for about 900 chemicals known to cause cancer or birth defects.
