Project: The use of audiorecorders for the detection of a rare and threatened species of primate from the Atlantic Forest, the black-lion tamarin, Leontopithecus chrysopygus

 

Abstract: Vocalizations are important ways of social interaction among many primate species, which can used to warn the members of the group, intimidate possible rivals, play or to show stress. However, primate vocalizations within the same family are quite similar, making the differentiation between them difficult. The study aims to test the capacity of the audiorecorders identifying the specific vocalizations of the black-lion tamarin (Leontopithecus chrysopygus, Callitrichidae), in the São Carlos Ecological Park, São Paulo, Brazil, from vocalizations of other primate species belonging to the same family or to others family. Besides, we will also test the range capacity of detection by these devices, i.e. how far the vocalizations are detected in a readable form for the program. Once the black-lion tamarins are found in low densities in the Atlantic Forest, traditional methods of census such as line transects and playbacks are poorly efficient, which would make the use of audiorecorders an interesting alternative for later studies.
