An autonomous recording unit or ARU is a specialized device designed to autonomously capture environmental sounds. Simply put, it is a rugged box with microphones that is programmed to record the environment around it over long periods of time.
ARUs have the capacity to capture sound-producing species across environments. Whether it involves the harmonious melodies of the American Robin, the vernal calls of a toad, or the echolocation signals of a bat, there are makes and models of ARUs equipped to document different groups of species.
Species such as birds, amphibians and bats can all be reliably tracked with sound technology. Understanding species populations, movements, or associated changes to the soundscape are pivotal to the greater understanding of the environment.
Comparing the efficacy of ARUs to point counts requires a nuanced evaluation of research objectives and environmental contexts. While ARUs offer continuous and automated sound recording, point counts introduce confirmation with visual and behavioural observations. The choice depends on the specific research goals and the comprehensiveness of data desired. ARUs offer the ability to easily conduct repeat temporal sampling in a specific location whereas a human observer can visit more places, but potentially only once.
The optimal deployment duration, recording schedules, and placement strategies of ARUs depend on the species under investigation and the research questions at hand. For instance, conducting in-depth analyses of long-term soundscapes needs precise recording schedules for extended periods of time. Conversely, longer consecutive recording sessions or more frequent extended recordings might be essential for tracking individual movements or space use.
Sonic ARUs are designed to capture sound within the audible range of human hearing. They are most commonly used to record birds and other environmental sounds. Ultrasonic ARUs are specialized devices to capture sounds in the ultrasonic frequency range, that is, beyond the range of human hearing. Ultrasonic recorders can help study more cryptic species like bats and rodents.
Humans cannot directly hear ultrasonic sounds. However, ultrasonic sounds can be effectively shifted into audible frequencies by slowing down the playback speed. Scientists usually do not rely on the converted audio to identify species, but instead rely on spectrograms, which are visual representations of the sound.
