Bats are crucial for maintaining robust ecosystems. Yet, studying them comes with significant challenges, given their nocturnal behavior, small body sizes, flight capabilities, and tendency to occupy difficult to access locations. To unravel the mysteries surrounding these enigmatic creatures, Northern Arizona University’s Bat Ecology and Genetics Lab leverages cutting-edge genetic technologies. By isolating minute traces of DNA left behind when bats defecate, feed and even fly, we can gain critical insight into their ecology. Join Savannah Marriott as she explains how through the innovative use of DNA analysis, we can illuminate the hidden lives of bats, and empower conservation efforts aimed at safeguarding their populations and the ecosystems they support.
