Mammal Program

River OtterFollowing BRI's initial work on mink and river otters, the mammal program quickly expanded to incorporate studies of other aquatic dwelling animals, including bats. There are more than 1,105 known species of bats, comprising nearly a quarter of all mammal species. In the U.S., more than half of the bat species forage adjacent to waterways. Bats are also long-lived (up to 30 years for some) and have the potential to accumulate high levels of toxins over time.These unique and mysterious creatures are at the center of some of today's most pressing ecological issues, such as white-nose syndrome, a deadly fungus, and mortality associated with wind turbines. BRI biologists, collaborating across several programs, are conducting studies to address these issues.

“The first time I worked with bats,
I was amazed at how small and
delicate they are."
