The April JASA Express Letters cover features a photo of a moose, taken by Remington J. Moll, one of the coauthors of the article, “Characteristics of wild moose (Alces alces) vocalizations.” Other authors on the article include Alex Zager, Sonja Ahlberg, Olivia Boyan, Jocelyn Brierley, Valerie Eddington, and Laura N. Kloepper. The article discusses vocalizations of moose, which are actually understudied acoustically!
