The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

The global population speaks approximately 7,000 different languages and approximately half of the world’s population is bilingual. The unique orthographic characteristics of different languages can help us to gain insight into the seemingly simple process of transforming written to spoken words (i.e.,…
