Ants are the glue that hold forests together. But Madagascar’s hotspots of biodiversity are vanishing, and along with them unknown species. An estimated 40% of the island’s species have already perished through human encroachment.
Few species communicate in a way remotely as complex as humans. Gelada monkeys are an exception. Geladas ‘talk’ to each other with complex sequences of sounds, but the function of these melodies is a mystery.
