The Frogs’s Songs

Since 2012, we started a new research program working on two different fronts. First, we are characterizing advertisement calls of Andean frogs. Second, we are implementing an automated acoustic monitoring of frogs and birds on the eastern slope of the Cordillera Central in Antioquia. We are collecting a significant amount of data that will allow us to complement our inferences on the demographic studies in the region. We are also challenged by the complexity of the data and we have an active collaboration with the Department of Electric Engineering at the Universidad de Antioquia to design and implement artificial intelligent algorithms to analyze sound data. With this research program we aim to demonstrate the benefits of passive monitoring strategies to infer the effect of human disturbances on the presence and activity of frogs and birds in the Andean ecosystems.
