About Presbytis rubicunda (Müller, 1838)
Common Names and Taxonomy
Presbytis rubicunda, commonly known as the maroon langur, maroon leaf monkey, or red leaf monkey, is a species in the family Cercopithecidae.
Endemic Range
It is endemic to Borneo, a Southeast Asian island, and the smaller nearby island of Karimata.
Habitat Altitude and Type
This species mostly inhabits forests at altitudes below 2,000 m, and its primary habitat is dense dipterocarp evergreen forest.
Borneo Ecosystem Characteristics
Borneo, which hosts healthy tropical rainforest, also includes shallow, swampy areas with acidic, decomposed plant matter; these areas experience seasonal dry periods, and rivers in these regions rise around two meters during the wet season.
Diet
Presbytis rubicunda feeds on leaves, seeds, and fruits.
Arboreal Behavior
It is an arboreal primate that spends most of its time in the forest canopy.
Home Range and Population Density
Compared to other primates, maroon leaf monkeys have large home ranges and low population densities.
Driver of Population Pattern
This pattern is thought to result from their reliance on specific rare, widely dispersed trees.
