Amphibians’ permeable skin makes them incredibly sensitive to changes in their environment. Scientists and conservationists alike are using them as “sentinel species” that could provide early warnings of ecosystem change and stress affecting them and other organisms. Next time you are out, stop and listen. Do you hear them?

When bats detect an insect from returned echolocation calls they rapidly increase the pulse rate and raise the frequency of calls in order to gather more information on the insect including location. These calls emitted right before a bat closes in on an insect are called terminal phase calls or "feeding buzzes".
