In this episode, professor Anne Axel of Marshall University makes the case for a new field of bioacoustics research: soundscape phenology, the study of cyclical life events of plants and animals via sound recordings. She'll be keynoting the biennial Ecoacoustics Congress in Brisbane, Australia later this month on the topic, and gives us a preview while playing just a few of the recordings that have informed this research from the forests of Madagascar.
