Abstract

MONTOYA, Diana C. Duque; NARVAEZ, Claudia V. Isaza  and  ROJAS, Estefany Cano. Comparison of Espadarana Prosoblepon Vocalizations in Two Different Ecosystems using Hierarchical Clustering. RISTI [online]. 2017, n.24, pp.13-21. ISSN 1646-9895.  https://doi.org/10.17013/risti.24.13–21.

Espadarana prosoblepon vocalizations were analyzed in two different ecosystems, a conserved forest near to a dam in southeast Antioquia and a disturbed forest in Carmen de Atrato, Chocó. The recordings were segmented, then processed to extract and select features and classified with a hierarchical algorithm. To analyze more generally the results, Sachatamia albomaculata vocalizations from the dam were processed too.  The results show that the species vocalizations are clearly affected by the environment, and the three types of vocalizations can be separated with the proposed methodology

Keywords : Espadarana prosoblepon; bioacoustics; dendrogram; ecosystems.
