About Bret

Bret Pasch serves as Associate Professor of Wildlife Conservation and Management in the School of Natural Resources and the Environment at The University of Arizona. He holds a PhD in Zoology from the University of Florida (2011), an MS in Wildlife Science from The University of Arizona (2004), and a BS in Biology from Ursinus College (2001). Pasch's research applies principles of animal behavior, communication, and sensory ecology to wildlife conservation and management. His work encompasses bioacoustics, mammalogy, and natural history, with particular focus on vocal production mechanisms and acoustic signaling in rodents, including grasshopper mice, singing mice, and woodrats. He examines gut microbial communities' responses to dietary changes across rodent species, food caching behaviors in mammals, and the use of autonomous recording units for monitoring endangered species such as the Mount Graham red squirrel and western yellow-billed cuckoo. Additionally, Pasch investigates how forest management impacts communication distances in endangered tree squirrels and variation in vocal responses to conspecific and heterospecific advertisement vocalizations in sympatric grasshopper mice.
