Wild animals fear humans more than lions, study finds
1.
The lion has long been regarded as the world's most i) fearsome terrestrial carnivore, but the
"king of beasts" has been toppled by humans, new research shows. Elephants, rhinos and giraffes are
all now more afraid of people than other apex predators, according to a scientific paper that supports
the idea that humans are the world's "super predator". Wild ii) animals are twice as likely to run away,
and iii) abandon waterholes 40% iv) faster when they hear the sound of people talking, according to
researchers working in South Africa's Greater Kruger national park, home to one of the largest
remaining lion populations.

Running away or abandoning the a) waterhole was a response seen in 95% of b) species, which
included giraffes, leopards, hyenas, zebras, kudu, warthog and impala. c) "Fear of humans significantly
exceeded that of lions throughout the savanna mammal community," according to the paper,
published in Current Biology. The sounds played were the voices of men and women speaking calmly
in local languages. Lead researcher Prof Liana Zanette, from the University of Western Ontario in
Canada, said she was surprised bv the magnitude of the response from wildlife, as well as the number
of species affected. "Lions should be the scariest thing out there - but humans were much scarier ...
It shows we really are terrifying to animals," Zanette said. She described the findings as "amazing but
depressing too".

Fear itself can have enormous i) effect/ effects on animal populations: fleeing a perceived
threat often comes at the expense of eating and staying in good condition. "Running away from the
waterhole ii) means/mean) they will have to find another place to drink-that is a iii) costs/cost," said
Zanette. Surveys from Australia, North America, Europe and Asia have shown humans kill prey at
higher rates than any other apex predator - partly due to the adoption of guns, and hunting with dogs
- which is why they have gained the title of "super predator". Research from other parts of the world
has shown mountain lions, deer, kangaroos, wallabies and wild boar all fear humans more than other
apex predators.

This human-induced "landscape of fear" will have cascading effects down the food chain, right
down to rodents and plants, as it changes the way animals move through landscapes. It is likely to have
"considerable ecological impacts", researchers said. "If the fear of humans is so pervasive and happens
to all animals out there on our planet, then it really adds a new dimension to the worldwide
environmental impacts that humans might be having," said Zanette.

Wildlife researcher Dr Hugh Webster, who did not work on the study, said the research
indicated that "human impacts on animal behaviour are even more wide-reaching than we thought.
Perhaps the key point is that we need to identify the most disturbance-sensitive species and engineer
protections for them that allow freedom from this pervasive fear." To conduct the study, researchers
used hidden camera-speaker systems at waterholes that were triggered when an animal passed within
10 metres. Waterholes is chosen as the locations because this are where lions - and hunters - tend
to kill prey. The researchers filmed the response of the animal to the sound of either humans speaking
or lions snarling, growling or making hunting noises, and used non-threatening bird calls as the control
sound.
