When a lion decides to chase down a zebra it seems as though nothing can stop it. But now researchers have discovered these enormous predators are being thwarted by a tiny foe: ants.

Scientists have found the spread of big-headed ants in east Africa sets off a situation leading to lions making fewer zebra kills.

Prof Todd Palmer of the University of Florida, a co-author of the research, said the findings were a surprise. “I was stunned,” he said. The fewer kills appear to be due to the upending of a crucial relationship – between native ants and the trees in which they live, causing a loss of cover for lions.

Acacia ants protect whistling-thorn trees by biting and stinging elephants looking for a snack.

To unpick the wider ecological impacts Palmer and colleagues first studied a number of plots in Laikipia, Kenya, some where elephants were present, some where they were excluded.

The team found that when big-headed ants and elephants were present there was a drop in tree cover and a dramatic increase in visibility.

About

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species. Read more...
