To find out about habitats, species and ecosystems are faring, don't just look, writes Ella Browning. Listen! Many species are hard to see, but have distinct auditory signatures, and advances in electronics suggest a future of landscapes 'wired for sound' feeding data streams for ecological analysis, not to mention detecting criminal activities from 'black' fishing to illegal logging and hunting.
