New App Identifies Species
By Recordings of Their Vocalizations
A new app is enabling scientists and the public to automatically identify frogs, birds, insects, monkeys, and other animals by recording their vocalizations.
Scientists at the University of Puerto Rico have created a system called the Automated Remote Biodiversity Monitoring Network (ARBIMON) that enables them to place inexpensive, solar-powered technology in the field and record the sounds of creatures that are often difficult to see or locate in their natural environment. The devices, which include I-Pods, can make 144 one-minute recordings per day and transmit them to a base station miles away. Using the ARBIMON system
, scientists have already made more than 1 million recordings in Puerto Rico, Hawaii, Arizona, Costa Rica, and Brazil that can be listened to online. Researchers say the new system will greatly enhance their ability to do field research and to monitor the presence and activity patterns of species.
