Deep dives
Humans as Super Predators
Researchers have found that humans are considered super predators due to their high rates of killing prey. A study conducted in the Greater Kruger Area of South Africa showed that wildlife were more afraid of human voices than lion voices. The animals exhibited fear responses, running away and leaving water holes faster when hearing human voices compared to lion voices.
Ecological Impact of Human Presence
The fear that wildlife have towards humans can have ecological impacts. Prey animals display anti-predator behaviors, such as running away and remaining vigilant, which can affect their ability to find food and maintain population numbers. With over 8 billion humans on the planet, the mere presence of humans can have a profound impact on wildlife populations.
Conservation and Ecotourism
The research has implications for conservation efforts and ecotourism. Understanding how animals perceive humans, particularly in ecotourist areas, can help mitigate fear responses and create strategies to benefit wildlife and conservation. By studying and analyzing the sound cues associated with human presence, researchers aim to better understand the impact humans have on the planet and take steps to protect vulnerable species, such as rhinos, from poaching.
Ian Sample meets the conservation biologist Liana Zanette, whose recently published research demonstrates that humans are now the super predator, inciting more fear in wild animals than even lions. She explains the ramifications of this knowledge for conservation techniques and the protection of endangered animals. Help support our independent journalism at theguardian.com/sciencepod
