Abstract: | Background The degree to which loud-calls in nonhuman primates can be used as a reliable taxonomic tool is the subject of ongoing debate.
A recent study on crested gibbons showed that these species can be well distinguished by their songs; even at the population
level the authors found reliable differences. Although there are some further studies on geographic and phylogenetic differences
in loud-calls of nonhuman primate species, it is unclear to what extent loud-calls of other species have a similar close relation
between acoustic structure, phylogenetic relatedness and geographic distance. We therefore conducted a field survey in 19
locations on Sumatra, Java and the Mentawai islands to record male loud-calls of wild surilis (Presbytis), a genus of Asian leaf monkeys (Colobinae) with disputed taxanomy, and compared the structure of their loud-calls with a
molecular genetic analysis. |
