By tracking seven mountain lions that had been fitted with GPS collars, the team showed that the animals kept their distance from the grids, and moved more cautiously, when humans could be heard. Using camera traps, the team saw that medium-size carnivores were also perturbed: Bobcats became more nocturnal, skunks became less active, and opossums spent less time foraging.
To the rodents, the speakers provided a human shield. And as this study suggests, their fear can reshape ecosystems. Read: The predator that makes great white sharks flee in fear. Crucially, these effects are separate from all the other things that humans do to animals, from destroying habitats to hunting them directly. We tried to get past all of that and isolate the perceived presence of humans, separate from all the other disturbing things we do. In Wales, a farmer was hospitalised after being repeatedly bitten on his arms and legs by one of his pigs which pinned him against a tractor.
However, there have been a number of reports of farmers falling or collapsing from a medical emergency in a pig sty, then being eaten by their undiscerning livestock. Biologist Adam Hart explores our relationship with some of the animal kingdom's deadliest predators, and speaks to experts in human-wildlife conflict dedicated to reducing attacks on both humans and predators in Africa and India.
The year-old climate campaigner describes the events of the last incredible year of her life. Journalist and author Ella Whelan asks if contemporary feminism is, well, dead. Gordon Corera asks if the West is losing the technological race with China.
The story of one misleading post, and how we can all stop the spread of bad information. Radio 4 in Four. Main content. Six animals that eat people. You must enable JavaScript to play content. Beast v. Leopards and tigers. The theory says primates have been prey for millions of years, a fact that greatly influenced the evolution of early man. Sussman co-authored the book with Donna L. Hart, Ph. The book is scheduled to be released March 1. Sussman says our intelligence, cooperation and many other features we have as modern humans developed from our attempts to outsmart the predator.
Since the discovery of the first early humans, australo-pithicenes , which lived from 7 million years ago to 2 million years ago, many scientists theorized that those early human ancestors were hunters and possessed a killer instinct.
Through his research and writing, Sussman has worked for years to debunk that theory. An expert in the ecology and social structure of primates, Sussman does extensive fieldwork in primate behavior and ecology in Costa Rica, Guyana, Madagascar and Mauritius.
And examine the evidence they did. Bears: Earlier this summer, a hiker was attacked and killed by a grizzly bear in Yellowstone National Park. It was the first fatal bear attack in Yellowstone since Your best option when traveling in bear country is to find out which species you may encounter, learn about them and prepare yourself with the proper knowledge and equipment so you can be ready in the case of an attack. Sharks: What would summer be without stories of shark attacks?
These attacks are real—there are several dozen each year worldwide and a few fatalities—though the hype some years is far greater than the danger. Komodo dragons: The most famous victim of a komodo dragon attack has to be Phil Bronstein who, in when he was married to Sharon Stone, lost his big toe to one of these big lizards. These giant, carnivorous lizards, native to Indonesia, use sharp teeth, and possibly venom, to bring down large prey , such as pigs, deer and water buffalo.
