Geographic populations of Sulawesi tarsiers differ conspicuously in the acoustic structure of
the loud duet calls produced by mated pairs. There is evidence that the differences in call …

A most conspicuous vocal behavior of Sulawesi tarsiers is the loud calls that males and
females coordinate into duets. Differences in the acoustic structure of this display relate to …

Recent work on the tarsiers of Sulawesi indicates that the degree of species differentiation is
greater than has hitherto been thought. This is indicated by the acoustic differences between …

On the basis of morphological, anatomical, and acoustic analyses, the tarsiers of the Gimpu
region on Sulawesi belong to a previously undescribed species of the genus Tarsius Storr …

This study uses field surveys of wild tarsier populations to assess the relationship between
described tarsier taxa and acoustic forms. Surveyed regions of North and Central Sulawesi …

On the basis of distinguishing characteristics of various genetic markers, pelage color, tail
tuft, and vocalizations, we describe a new species of the genus Tarsius Storr 1780. The new …

Although the vocalizations of spectral tarsiers have been studied for over 3 decades by
numerous primatologists, the data in this paper represent the first evidence that this species …

A new, critically endangered species of tarsier, one of the world's 25 most endangered
primates, is described from the remote island of Siau, North Sulawesi, based on …

Introduction At present, four species of tarsiers are recognized: Tarsi us syrich ta Linnaeus,
1758 [1], from the Philippines; Tarsius bancanus Horsfïeld, 1821 [2], inhabiting Kalimantan …

We present a method for making best guess estimates for the conservation status of 20
Indonesian tarsier taxa and populations listed in the taxonomy of Brandon-Jones et …
