Relaxed open-mouth display serves important social functions in relation to submission, reconciliation affiliation and reassurance among non-human primate societies; however, quantitative evidence on this behavior remains insufficient among multi-level social groups. From July to November 2016, we examined four potential functions of the relaxed open-mouth display during pairwise, intra-unit social interactions among 18 free-ranging adult and sub-adult golden snub-nosed monkeys(Rhinopithecus roxellana) who belonged to three one-male, multi-female units(OMU) at Dalongtan, Shennongjia National Park China. Results showed that: compared with no relaxed open-mouth display,(1) the occurrence of displacement by a dominant individual approaching a subordinate was lower and the distance of the subordinate to the approaching dominant was shorter when the subordinate showed open-mouth display;(2) relaxed open-mouth display reduced the probability of continued attack for victims of aggression and allowed victims to achieve closer proximity to the aggressor during post-conflict periods;(3) relaxed open-mouth display by dominant individuals allowed them to achieve closer proximity to subordinates; and(4) the exchange of relaxed open-mouth display had a greater impact on the outcome of interactions than one individual alone giving this signal. These findings suggest that relaxed open-mouth display serves important functions regarding submission, reconciliation, affiliation and reassurance in coordinating social interactions within OMUs in golden snub-nosed monkeys.

Potential priority areas and protection network for Yunnan snub-nosed monkey(Rhinopithecus bieti) in Southwest China

In Southwest China, five Nature Reserves(NRs)(Mangkang, Baimaxueshan, Yunling, Habaxueshan, and Yunlongtianchi) play a key role in protecting the endemic and endangered Yunnan snub-nosed monkey(YSM)(Rhinopithecus bieti). However, increasing human activities threaten its habitats and corridors. We used a GIS-based Niche Model to delineate potential core habitats(PCHs) of the YSMs and a Linkage Mapper corridor simulation tool to restore potential connectivity corridors(PCCs), and defined five scenarios. A normalized importance value index(NIVI) was established to identify the protection priority areas(PPAs) for the YSMs for five scenarios. The results indicated that locations of the habitats and corridors were different in the five scenarios, thereby influencing the distribution of the PPAs and protection network of the YSMs. The NIVI value of Baimaxueshan nature reserve was 1 in the five scenarios, which implied the maximum importance. There were only 7 PCHs and 16 PCCs(with the longest average length of 223.13 km) which were mainly located around 5 NRs in scenario III. The protection network of the YSMs was composed of 16 PCHs, 18 PCCs, and 5 NRs. Under each scenario, most of the PCHs and the PCCs were located in the south of the study area. The five NRs only covered 2 PPAs of the YSMs. We suggest that the southern part of the study area needs to be strictly protected and human activities should be limited. The area of the five NRs should be expanded to maximize protection of the YSMs in the future.

The experimental plots in representative areas of the Shennongjia Nature Reserve were *** forest communities in Shennongjia were investigated by using *** plant communities in these plots were investigated to discern the pattern of species diversity distribution along the altitudinal ***α-diversity andβ- diversity were calculated by using the data collected. Theα-diversity of the tree layer peaked in the evergreen broadleaved forest zone at low-elevation, theα-diversity of the shrub layer increased gradually at first and then decreased along the altitudinal gradient,while theα-diversity of the herb layer peaked in ***β-diversity peaked at mid-elevations where the composition of edificatory species *** transition zone was characterized by relatively high levels of species diversity and species turn-over *** overall species richness peaked in *** results of this research could provide a sound basis for reserve management and planning,as well as preservation of Sichuan snub-nosed monkey in this reserve.
