We present the spectrographic description of the vocal repertoire of the Philippine tarsier
(Tarsius syrichta fraterculus), a solitary living nocturnal primate for which a very limited …

Some previous genetic studies have been performed to resolve the molecular phylogenetics
of the squirrel monkeys (Saimiri). However, these studies did not show consensus in how …

The continuity of phylogenetic descent requires that sister taxa originate in the same place
and at the same time. Resolving phylogenetic relationships can therefore aid in …

The Asian common toad (Duttaphrynus melanostictus) is a human commensal species that
occupies a wide variety of habitats across tropical Southeast Asia. We test the hypothesis …

The Bali (Panthera tigris balica) and Javan (P. t. sondaica) tigers are recognized as distinct
tiger subspecies that went extinct in the 1940s and 1980s, respectively. Yet their genetic …

Sulawesi, the largest island in the Indonesian biodiversity hotspot region Wallacea, hosts a
diverse endemic fauna whose origin has been debated for more than 150 years. We use a …

Until recently the conservation status of seven of the nine species of tarsier on the IUCN Red
List was Data Deficient, and determining the status of these species has been a priority. In …

New World primates comprise a diverse group of neotropical mammals that suddenly
appeared in the Late Oligocene deposits of South America at around 26 million years ago …

Abstract In 1917, Henry C. Raven obtained a small-bodied tarsier from upper montane rain
forest in the mountains of Central Sulawesi. Miller and Hollister (1921b) designated the …

One of the sharpest biogeographical transitions in the world occurs between the Indonesian
islands of Borneo and Sulawesi; this transition is demarcated by Wallace's line. Macaque …
