Also, Which technology are environmental scientists using to track gray wolves by their individual howls?

The team created custom sound analysis software using algorithms that took frequency and amplitude into account in order to solve this issue. In a previous research, scientists identified six captive eastern gray wolves by their howls using this method. With 100% accuracy, they were able to recognize the wolves.

People also ask, What technology do Wildlife biologists use to study polar bears?

They discovered free-roaming polar bears for the first time using infrared equipment. New opportunities for observing animals that roam the vast, distant Arctic and traverse international boundaries are made possible by this joint, creative study.
