For Hakai Magazine, Trina Moyles introduces us to Jesika Reimer, a chiropterologist who is leading the world’s first gene-flow study to better understand the hibernation patterns of bat colonies in Alaska. Bats, who have a bad rap as vectors for rabies, are little understood for the critical and varying roles they play in the environment.
Bats are incredibly diverse in their adaptations. They’re the only mammal capable of true flight, living on every continent except Antarctica. Next to rodents, bats are the second-largest mammal group in the world, with over 1,400 documented species and counting. These range from massive fruits bats—the size of a small human child—to the tiny bumblebee bat, which weighs in at just two grams. The fish-eating bat, meanwhile, has elongated feet for raking the surface of the water to catch fish and crustaceans. And the Mexican long-tongued bat uses its long, tubular tongue—nearly half the length of its body—to feed on nectar. Bats are the major pollinators of over 500 different plant species, boosting both natural habitats and human agriculture.
Despite these wonders, the bat has an unfair reputation as a “bloodthirsty, rabies-carrying rodent,” Reimer says. “In North America, less than two percent of wild bats test positive for rabies, a number significantly lower than, say, foxes,” she points out. In 2021, only three people in the United States died from rabies contracted from bats.
