The American bullfrog (Lithobates catesbeianus) is an invasive amphibian that creates problems for native species around the world. In southeast Arizona, permanent water sources are few and far between, creating a uniquely harsh environment for amphibians, yet bullfrogs still prosper in this environment and threaten native herpetofauna and other wildlife. Efforts to eradicate bullfrogs are underway, but since these efforts are time consuming and expensive, it is important to ensure they're effective by using specific knowledge of bullfrog ecology. During this lunchtime webinar, dive into Emma's efforts to understand bullfrog movement and reproductive ecology as she explores her time working with this invasive species within the diverse landscapes surrounding the Appleton-Whittell Research Ranch.

About the Speaker: Joining us this year as a first-year master’s student out of the University of Arizona’s School of Environment and Natural Resource and with the guidance of the Arizona Game and Fish Department, Emma is working to gather the data needed to manage one of the greatest threats to Arizona’s aquatic wildlife, the invasive American bullfrog (Lithobates catesbeianus). Through her research, she hopes to fill gaps in knowledge around bullfrog dispersal and reproductive ecology, providing wildlife managers the best available data with which to inform their eradication efforts. With a landscape level approach and sites including the Huachuca Mountains, Canelo Hills, and Babacomari Ranch, Emma’s work will undoubtedly benefit the Research Ranch as we work to control this invasive species within our own borders.
