Dominance, aggression and physiological stress in wild male Assamese macaques (Macaca assamensis)

In this article, we attempt to characterize the widespread trade in pet macaques in Vietnam. Data on confiscations as well as surrenders, releases, and individuals housed at rescue centers across Vietnam for 2015–2019 were opportunistically recorded. Data comparisons between Education for Nature Vietnam and three government-run wildlife rescue centers show that at least 1254 cases of macaque keeping occurred during the study period, including a minimum of 32 Assamese macaques (Macaca assamensis), 158 long-tailed macaques (Macaca fascicularis), 291 Northern pig-tailed macaques (Macaca leonina), 65 rhesus macaques (Macaca mulatta), and 110 stump-tailed macaques (Macaca arctoides). A minimum of 423 individuals were confiscated, and at least 490 individual macaques were released. Three semi-structured interviews were conducted with two key Animals Asia (a non-governmental organization) colleagues and their insights are presented. Although we recognize that the data included are limited and can serve only as a baseline for the scale of the macaque pet trade in Vietnam, we believe that they support our concern that the problem is significant and must be addressed. We stress the need for organizations and authorities to work together to better understand the issue. The keeping of macaques as pets is the cause of serious welfare and conservation issues in Vietnam.

Assamese macaque Macaca assamensis McClelland, 1840 is one of the primate species with narrow distribution range and the least exploration. This study investigated the diurnal activity of Assamese macaque and association with the vegetation in Nagarjun Forest of Shivapuri Nagarjun National Park, Nepal. Behaviour sampling including Instantaneous sampling and Ad-libitum sampling (7:30 AM – 4:30 PM) along with vegetation survey (20 m × 20 m plots) were applied. The Raniban Barrack troop of Assamese macaque composed of 12 individuals was observed for a total of 225 hours to record the macaque’s diurnal activity. The troop spent 28% time in inactive, 25% in grooming, 23% in foraging, 23% in locomotion and 1% in fighting. Assamese macaque troop spent more time in Schima wallichii possessing 25.91%, 36.29% and 41.22% for foraging, locomotion and inactive respectively of the diurnal time. Altogether, 67 plant species (herbs, shrubs, trees and climbers) were documented from vegetation analysis. Schima wallichii and Ardisia macrocarpa were dominated the habitat. Paired t-test revealed significant difference in foraging (df = 24, P = 0.010) and inactive (df = 24, P = 0.003) between the morning and day observational phases. The findings of this study shed light on the food preference and microhabitat use by the protected Assamese macaque in Nepal that assists to formulate the management plans for the species.

This study was focused on Macaca assamensis general behavior and vegetation associated with their habitats in Kaligandaki River Basin at Baglung and Parbat Districts of Nepal. The field survey was conducted from December, 2015 to May, 2016 to explore the Assamese Macaque general behavior and vegetation associated with their habitats. Total area of 104.70 km2 was surveyed, vegetation analysis was done by random quadrates sampling method and behavioral data were collected by scan sampling method. A total of 47 individuals of Assamese Macaques (Macaca assamensis) were counted in four different troops. Total of 2240 scan samples were recorded from the four different troops during this study period the scan samples revealed that foraging was 47%, moving 28%, resting 14% and grooming 11%. In the context of daily activity pattern for aging time of Assamese monkey was found to be highest 54% in 15:00 to 18:00 observational phase and lowest 40% in the observational phase of 12.00 to 15.00 hours. Moving time of the Assamese monkey was found to be highest 33% in 12.00 to 15.00 observational phase and lowest 22% at 15:00 to 18:00 observational phase, resting time of Assamese monkey was found to be highest 15% in 09:00 to 12:00 hours and lowest 13% in 15:00 to 18:00 observational phase and Assamese monkey were seen mostly grooming 13% in 12.00 to 15.00 hours and lowest 10% in 15:00 to 18:00 observational phase. By quadrate sampling, 58 plant species with 716 number were recorded. Sal (Sorea robusta) was the dominant plant species with relative density 31.42% and relative frequency 8.376% which was followed by Tiju (Diospyros malabarica)with relative density 10.93% and relative frequency 8.376%.Journal of Institute of Science and TechnologyVolume 22, Issue 1, July 2017, page: 110-119
