Golden langurs (Trachypithecus geei) are an endangered species in a limited area of Northeast India and Bhutan. They are confined to a forest belt in western Assam between the Manas River in the east, Sankosh in the west and Brahmaputra in the south along the Indo-Bhutan border. Due to habitat destruction, their populations are restricted to fragmented forest pockets, especially in India. We compared data on an isolated population of golden langurs in the rubber plantation of Nayakgaon in the… 
Status and Conservation of Golden Langur in Chakrashila Wildlife Sanctuary, Assam, India
Abstract: The golden langur, Trachypithecus geei, is an endangered species endemic to India and Bhutan. Its distribution is limited to a small forest belt in western Assam in Northeast India and
Biology, Ecology, and Conservation of Golden Langur, Trachypithecus geei
Activity pattern showed a bimodal diurnal activity pattern in feeding with peaks in the morning and evening hours, and Golden Langur is folivorous in nature and feeds on a variety of food plants.
Persistence of Trachypithecus geei (Mammalia: Primates: Cercopithecidae) in a rubber plantation in Assam, India
Examination of the population number and age-sex composition of the ‘Endangered’ Golden Langur Trachypithecus geei in a rubber plantation in the Kokrajhar District in Assam, India in 2016 and past data of the langur population and demographics are compared to better understand the population dynamics, demographic characters and persistence of the Golden Langurs in the rubber plantation.
Genetic Diversity and Structure among Isolated Populations of the Endangered Gees Golden Langur in Assam, India
The present study sequenced and analyzed around 500 bases of the mitochondrial DNA (mtDNA) hypervariable region-I from 59 fecal samples of wild langur collected from nine forest fragments to estimate the genetic diversity in the Indian population of golden langur and established that T. geei is monophyletic but revealed possible hybridization with capped langur, T. pileatus, in the wild.
Social organization of Shortridge's capped langur (Trachypithecus shortridgei) at the Dulongjiang Valley in Yunnan, China.
To understand its social organization, data is collected from five groups of Shortridge's langurs at Silaluo in the Dulongjiang valley during August 2012-October 2013, indicating the potential of a population increasing.
Conservation threats to the endangered golden langur (Trachypithecus geei, Khajuria 1956) in Bhutan
This paper classified and rank all direct threats to the endangered golden langur in Bhutan in order to provide a practical guide to future conservation of the species.
Influence of habitat conditions on group size, social organization, and birth pattern of golden langur (Trachypithecus geei)
It appears that group size is sensitive to forest type, and births are positively related to social and environmental factors, and the behavioral parameters may influence life-history traits if continuous habitat alteration persists.
Primate Conservation in the Rangeland Agroecosystem of Laikipia County, Central Kenya
Patas monkeys Erythrocebus patas, olive baboons Papio anubis, vervet monkeys Chlorocebus pygerythrus, and northern lesser galagos Galago senegalensis in the Laikipia rangeland agroecosystem benefit from man-made perennial water sources, habitat protection, reduced large predator densities, and an array of research and conservation activities.
The density and distribution of Ateles geoffroyi in a mosaic landscape at El Zota Biological Field Station, Costa Rica
The genus Ateles is thought to prefer primary forest, as spider monkeys are ripe fruit specialists and generally occupy the upper canopy of tropical forests. However, this generalization could be
Organochlorine insecticide poisoning in Golden Langurs Trachypithecus geei
Though no specific gross lesions were observed, histopathologically, centilobular hepatic necrosis, mild renal degeneration, necrotic enteritis, pulmonary congestion and neuronal degeneration were recorded in all three animals.


Status and distribution of golden langurs (Trachypithecus geei) in Assam, India
Demographic trends indicate a decline in the golden langur population, and small group sizes, isolated distribution, proportionately few infants and juveniles, and degrading habitat are all causes of concern.
Golden Langur Trachypithecus geei threatened by habitat fragmentation

The golden langurs (Presbytis geei Khajuria, 1956) of Assam
The ecology and behaviour of golden langurs were studied in the western forests of Assam and the similiarity and differences in their behaviour from those of Hanuman langurs have been discussed.
Further observations on the golden langur (Presbytis geeiKhajuria, 1956), with a note to capped langur (Presbytis pileatusBlyth, 1843) of Assam
In continuation of the field work that was initiated in the summer of 1973 another field trip to the same area of Goalpara district was undertaken in the winter of 1973 and later on a survey of Manas
Golden langur – distribution confusion
I refer to the item published in Oryx (25,124). The golden langur Presbytis geei is found in Bhutan and India's Assam state only. So the Indo-Bhutan or Assam-Bhutan boundary implies the same area.
The Golden Langur and the Manas Sanctuaries
Although first noted by E. O. Shebbeare in 1907, the golden langur monkey Presbytis geei was only named and described after E. P. Gee had found and photographed it in 1953 on the east bank of the
