“…Fecal cortisol measures in free-ranging female ring-tailed lemurs (Lemur catta) were significantly correlated with dominance indices: high-index individuals had high cortisol values and low-index individuals had low cortisol values (Cavigelli, 1999). Female sexual behavior is primarily correlated with physiological status, mate choice, and age in Rhinopithecus roxellana (Ren et al, 2000(Ren et al, , 2003. In the present study, F1 was the high-index individual and F2 was the low-index individual.…”

The Sichuan golden monkey is deserving of conservation and the welfare of this species is receiving increasing attention. However, it is difficult to identify physiological parameters for assessing its conservation status. In the present study, we employed noninvasive sampling methods and immunochemical assays to determine if measurements of cortisol and immunoglobulin in feces allowed monitoring of physiological status. The results indicated that the cortisol and immunoglobulin concentrations in feces could serve as biomarkers for monitoring stress and immune status, and that there was a relationship between stress and the immune response. A tendency toward seasonal fluctuation in immunoreactive cortisol and fecal immunoglobulin concentrations emerged, indicating that these indices could be useful tools for monitoring the welfare of the monkey and could be used in the field of wildlife research.

“…Despite a wide distribution in China during the Pleistocene [1], wild R. roxellana populations now only occur in 3 isolated mountainous regions. The total population size is estimated to number about 15000 [2,3]. Because of large-scale commercial timber exploitation between the 1950s and early 1980s, the habitats of R. roxellana in the Shennongjia Nature Reserve (SNR) became fragmented, and illegal hunting led to the capture of at least 130 monkeys in the 1970s and 1980s [4].…”

Effective population management relies on assessments of population size and sex ratio. However, these estimates are difficult to obtain for elusive and rare species. Recently, noninvasive genetic census methods have been developed as an alternative to traditional capture-mark-recapture methods. In this study, we estimated the size of the Sichuan snub-nosed monkey (Rhinopithecus roxellana) population in the Shennongjia Nature Reserve (SNR) using a noninvasive sampling method based on 16 microsatellite loci. We also used a PCR-based genetic method to sex the sampled individuals and infer the population sex ratio. The population size of R. roxellana in the SNR was estimated to be 1044 individuals (95% CI TIRM : 613-1409). The estimated population sex ratio is more female-biased than expected, which we attribute to the sampling biased towards one male units and limited sampling of bachelor male units. Moreover, there is no suggestion that the heavy traffic road through the reserve might block movement of monkeys. The results of this study indicate genetic assessments based on a noninvasive sampling method can provide useful information regarding populations of elusive primates.

“…Its natural social groups range in size from small groups of 5-10 individuals up to bands of more than 600. Previous studies on this species are preliminary and of short duration [8,9,[11][12][13][14]. Although the habitat, group size and forage of the species in the Qinling Mountains have been investigated [15][16][17][18], there have been few studies on their home ranges.…”

The seasonal changes in home range and habitat use of the Sichuan snub-nosed monkey, Rhinopithecus roxellana, have been studied by radio tracking and direct observation in the Qinling Mountains of China. The home range size was 14.1 km² in spring, 9.5 km² in summer, 12.1 km² in autumn and 12.3 km² in winter; the total area used was 22.5 km². The area of the home range is closely correlated with the distribution and abundance of food resources. Seasonal change in the home range area is correlated with the phenology of the vegetation. An unusually large home range is a unique characteristic of this monkey.
