In 1968, Robert H. Horwich of the Chicago Zoological Society, USA, came to India and studied the devastating impact of replacing Eucalyptus trees in the place of natural forest in the evergreen shola areas of the Nilgiri Mountains, causing the decline of indigenous fauna such as Nilgiri Langur (Horwich 1972). After that, he joined the Golden Langur Conservation Project to extend the work of the Indo-US Primate Project of 1994-2001, and was involved in community-based conservation programs in the Manas Biosphere Reserve (Horwich et al. 2010(Horwich et al. , 2013.

Awadhesh Pratap Singh University
Shivesh Pratap Singh (Singh 1984) carried out studies in Mand Reserve Forest, Madhya Pradesh, on habitat use and feeding by Hanuman Langurs and Rhesus Macaques. Later, his students worked on langurs and Rhesus Macaques in various parts of Satna District of Madhya Pradesh. Ravish Vachaspati Gautam (Gautam 2003) studied the feeding ecology and habitat utilization of langurs and Chetna Sharma (Sharma 2018) studied habitat utilization and feeding habits of Rhesus Macaques. A population survey was conducted from 2014 to 2015 in which a population density of 34.5 per km 2 was estimated in 2014, while 37.5 per km 2 was estimated in 2015 in Kardmeshwerdham Hill and 23.2 per km 2 was estimated in 2014, and finally 24.8 per km 2 was estimated in 2015 in Babupur Kaniyari. The adult male-female sex ratio of the Babupur Kaniyari group ranged from 1:3 to 1:3.5, while the Kardmeshwerdham group was found with an adult male-female sex ratio of 1:2.75 to 1:3.25.

large ranges and with access to many females, and settlers either without any female or associated with a female as a pair. These observation dispelled the previous notion that Slender Loris had a simple mating system.

Assam University
Anup Dey (Dey 2015) studied the status and distribution of Hoolock Gibbon in select reserve forest of Karimganj District, Assam. The level of anthropogenic disturbance (poaching, logging, jhum cultivation, and agricultural encroachment) had a significant impact on gibbon population. The study identified that the Patharia Reserve Forest was a better site for gibbon survival among all the forests in the district.
Mitrajit Deb (Deb 2018 (https://www.researchgate. net/profile/Mitrajit_Deb)) reported that Western Hoolock Gibbons that are known to be frugivores are consuming more leaves due to a dearth of fruiting trees. Loss of fruiting trees diminish habitat quality, and this may lead to severe nutritional stress in future. The study recommends taking up conservation programmes at a village council level (gram panchayats) to arrive at a participatory biodiversity conservation plan.

Pondicherry University
S. Rajeshkumar (Rajeshkumar 2017) reported that Nicobar Long-tailed Macaques inhabit natural habitats much of the time and consume food from a wide variety of plant species, but human settlements and agricultural activities often lead to numerous human-macaque hostilities that can enhance agonistic activities leading to severe fatality among individuals.

North Eastern Regional Institute of Science and Technology, Nirjuli, India
Parimal Chandra Ray (Ray 2017 (https://www. researchgate.net/profile/Parimal_Ray4)) identified the population structure of 10 preferred food tree species of the Western Hoolock Gibbon, of which only two, Chukrasia velutina and Alianthus integrifolia, had a reasonably good population structure. The level of anthropogenic disturbance had a significant impact on the variation of the population and regeneration status of those food plants of the gibbon.
Diana Ethel Amonge (Amonge 2019) studied various reproductive aspects of Eastern Hoolock Gibbon in Conservation Breeding Centre, Biological Park, Itanagar. She documented 94 mating attempts in which there were maximum attempts in January and minimum attempts in July. The estimated duration of each copulation was 28.4±1.2 seconds. The period of gestation was 189±0.92 days (n=14) and the average interval of birth for females whose infants survived or died after birth was 3.1±0.3 years and 1.5±0.2 years, respectively.

Tezpur University
Bidyut Sarania (Sarania 2019 (https://www. researchgate.net/profile/Bidyut_Sarania3)) recorded a total of 969 individuals comprising 41 troops (mean troop size was 23.63±1.21) of Macaca munzala from western Arunachal Pradesh within the altitudinal range of 1,400-3,000 m. The behavioral activities and the ranging pattern of M. munzala are significantly influenced by the seasonal availability of food items. It was found that only 2.4% of the landmass of the state was the possible habitat of the species.

Gauhati University
Anindita Chakravarty (Chakravarty 2020 (http://www. bijnicollege.ac.in/Departments/Science/Employee%20 Profile.aspx?did=12&eid=54)) studied the habitat utilization pattern, feeding, and population ecology of the Golden Langur in Kakoijana Reserve Forest, Assam. A total of 121 plant species comprising trees, shrubs, herbs and climbers used by Golden Langur as food items were recorded. Langurs were found to feed actively on Cyathea gigantea (Tree fern) along with Diplazium esculentum (Dhekia, a well-known edible fern of Assam), and mature leaves of Lygodium microphyllum.
Phoebe Laremruati (Laremruati 2020 (https://www. researchgate.net/profile/Phoebe_Lalremruati)) studied the behavior of the Pig-tailed Macaques Macaca leonina in captivity. Adult females spent most of their time grooming, followed by juvenile females, juvenile males, and adult males. The male infants attain independence earlier than the female infants. The rate of infection with gastrointestinal parasites was 61.82% in spite of all the anthelmintic treatments given. The monkeys breed during October and March.
