Abstract:

Monitoring of animal populations is a crucial tool for effective management, especially when the management goal is the conservation of a threatened or endangered species. Passive acoustic monitoring (PAM) is the new cost-effective method for obtaining information about animals that produce acoustic signals for communication. Because primates are among the globally most threatened taxa, this study is designed to assess the applicability of PAM on the genera Presbytis and Piliocolobus and further propose a methodology for the red leaf monkey (Presbytis rubicunda) to assess their abundance and population density and for the Bouvier's red colobus (Piliocolobus bouvieri) to detect their presence and map their distribution. The proposal, which should help support future projects focusing on these two species, is based on the gathered knowledge about vocal communication, PAM, automated recording units, data processing, biology, ecology, and vocalisations of the genera Presbytis and Piliocolobus. For the red leaf monkey (Presbytis rubicunda), the study site would take place in Sabangau National park in Central Kalimantan. Automated recording units (ARUs) would form a microphone array to assess location, abundance and population density better. For the Bouvier´s red colobus (Piliocolobus bouvieri), the study site would take place in the north-eastern part of Congo. ARUs would be deployed to cover the largest area to ensure the most likely detection of their presence. Avisoft SASLab Pro and The R Project for Statistical Computing would be used for data analysis and processing. Based on all the conclusions, the passive acoustic monitoring method seems to be appropriate for both species.
