Key Points

This research aims to explore how weak radiofrequency fields impact the navigation of migratory bats.
Migratory soprano pipistrelle bats were exposed to RF fields ranging from 0.01 to 300 megahertz.
The orientation of the bats was tested later at night compared to control groups.
Behavioral changes in flight orientation were observed post-exposure.
Control bats displayed normal orientation behavior while those exposed to RF noise exhibited irregular flight patterns.
The disruption in orientation suggests effects last beyond the immediate exposure to RF fields.

Abstract

How anthropogenic electromagnetic noise can affect living systems is a poorly understood impact of an increasingly urbanized natural environment, especially when occurring in a sublethal manner. In this study, we investigated impacts of weak-broadband radiofrequency (RF) fields on animal behavior. We exposed migratory soprano pipistrelle bats ( Pipistrellus pygmaeus ) to 0.01- to 300-megahertz RF fields and then tested their orientation later in the night. Whereas control bats oriented normally, bats exposed to RF noise exhibited random departure flight orientation, suggesting disruptive effects lasting beyond immediate exposure. These findings suggest that electromagnetic pollution has the potential to have a greater effect on animal behavior than previously assumed.
