Change of Enclosure in Langur Monkeys: Implications for the Evaluation of Environmental Enrichment

A group of Hanuman langurs (Presbytis entellus) was studied before and after it was moved from an old cage-style enclosure to a novel naturalistic environment at the London Zoo. Eating and locomotion occupied more of the langurs’ time in their new enclosure, whereas dozing, allogrooming, and aggression decreased, along with an increase in inter-individual distances. These changes are attributed...

Mitochondrial and nuclear markers suggest Hanuman langur (Primates: Colobinae) polyphyly: implications for their species status.

Recent molecular studies on langurs of the Indian subcontinent suggest that the widely-distributed and morphologically variable Hanuman langurs (Semnopithecus entellus) are polyphyletic with respect to Nilgiri and purple-faced langurs. To further investigate this scenario, we have analyzed additional sequences of mitochondrial cytochrome b as well as nuclear protamine P1 genes from these specie...

Habitat Utilization and Feeding Biology of Himalayan Grey Langur (Semnopithecus entellus ajex) in Machiara National Park, Azad Jammu and Kashmir, Pakistan.

Habitat utilization and feeding biology of Himalayan Grey Langur (Semnopithecus entellus ajex) were studied from April, 2006 to April, 2007 in Machiara National Park, Azad Jammu and Kashmir, Pakistan. The results showed that in the winter season the most preferred habitat of the langurs was the moist temperate coniferous forests interspersed with deciduous trees, while in the summer season they...

The primary structure of langur (Presbytis entellus) pancreatic ribonuclease: adaptive features in digestive enzymes in mammals.

The primary structure of pancreatic ribonuclease from langur (Presbytis entellus) has been determined. This sequence differs from that of human pancreatic ribonuclease at 14 (11%) of the amino acid positions. Eight of these 14 differences involve changes of charge, with the langur enzyme having five fewer positive charges than the human enzyme. The difference in charge between human and langur ...
