Abstract

We describe a die-off of little brown bats ( Myotis lucifugus carissima) associated with acute intoxication with microcystin-LR in 2016 at Scofield Reservoir in Utah, US. High levels of this cyanotoxin in water from the reservoir and gastrointestinal content of bats supported this diagnosis.
