What is it about?
Bats use echolocation sounds to “visualize” their environment and their food targets, such as insects, during foraging. This paper reports differences in the echolocation pulses emitted by individuals of Himalayan Leaf-nosed bats in populations within geographically different regions in China.

Why is it important?
Species-specific sound pulses emitted for echolocation are relatively stereotypic to accomplish relevant neural computations within a highly specialized brain. This paper is important because it tests the role of genetic, morphologic and environmental factors in modifying acoustic parameters of intra-species echolocation pulses. It is important to discover if and the extent to which echolocation vocalizations can be modified across different populations despite the computational and neural constraints. The results suggest that neural tuning to acoustic parameters can be modified even within highly specialize brians.
