Since the discovery of biosonar by Griffin in the 1940s, laboratories have conducted detailed experiments on how bats produce and modify their biosonar calls, as well as on how they detect and process self-generated echoes when orienting and hunting in flight rooms. The combination of recording the calls of bats and the ease of keeping and training bats in captivity has made bat biosonar one of the most extensively studied sensory systems under controlled laboratory conditions. While such settings are ideal for testing specific hypotheses, they are less useful for understanding how bats use echolocation to solve biologically relevant tasks in their evolutionary environment.

Gene knockout (KO) strain collections are important tools for discovery in microbiology. , a human fungal pathogen, has an available genome-wide gene deletion collection that is widely used by the research community. We uncovered mix-ups in the assembly of the commercially available deletion collection of ~4,700 unique strains acquired by our laboratory.
