THE ANIMAL FILES

Bonobo

Pan paniscus

Fruit eaten today can become a seed journey through the forest.

Bonobos inhabit humid forest in the Democratic Republic of Congo, south of the Congo River. Fruit is central to their diet, but their meals also include other plant parts and animal foods. As they move and feed, they help transport seeds away from the plants that produced them.[1]

A river between close relatives

The Congo River separates the main ranges of bonobos and chimpanzees, with bonobos to the south and chimpanzees to the north. The bonobo’s native range lies in humid forest between the Congo and Kasai rivers. This gives an animal with a familiar ape outline a specific geographical identity rather than an interchangeable “African jungle” setting.[1]

Fruit does not mean fruit only

Bonobos are fruit-focused omnivores. Leaves, honey, eggs, invertebrates and meat from small vertebrates supplement the fruit they consume. Observations of animal food should not erase the importance of fruit, and the prominence of fruit should not turn the species into a strict vegetarian. Both are supported parts of its feeding ecology.[1]

Carrying seeds without carrying a basket

Seeds swallowed with fruit can pass through the digestive tract and be deposited in faeces after the bonobo has travelled. Studies document viable seeds and improved germination for some plants. This moves some seeds away from the parent plant; dung beetles may then move them again. The benefit varies among plants, so it is not a promise that every swallowed seed will become a tree.[1]

A COMMON MIX-UP

Are bonobos entirely non-aggressive apes?

No. Wild studies document aggression, and comparisons with chimpanzees depend on behaviour and setting. A peaceful stereotype is too absolute.[1]

TRY A LITTLE REASONING

How could reducing fruit-eating animals change a forest even before trees disappear?

Reveal the explanation

It can change where seeds are deposited and their opportunities to germinate. Bonobos connect feeding sites with later seed deposition sites.[1]
