Chimpanzees have been hurling rocks at the same trees for more than a decade - Science Daily

A group of chimpanzees feeding together in a natural forest environment on Ngamba Island, Uganda. How likely is a chimpanzee (Pan troglodytes) to steal food from another chimp? It depends on whether they’re a friend or a foe. A team of biologists discovered that chimps pilfer less from their friends, and that the relationship between the victim and the thief influenced the emotional display of both parties. The findings are described in a study recently published in the journal Evolution and Human Behavior.

Scientists studying the tropical forests of Malaysian Borneo have discovered an unexpected shift in one of the region's long-running ecological partnerships. An international team from Queen Mary University of London, the Royal Botanic Gardens, Kew, the Biology Center of the Czech Academy of Sciences, and other institutions found that predatory wasps are increasingly occupying the hollow stems of the tropical plant Macaranga pearsonii. The findings, published in PeerJ, reveal that the wasps are moving into structures that evolved specifically to shelter protective ant colonies.
