effects of cold weather on the Sleeping Behavior of skywalker hoolock gibbons hoolock tianxing in seasonal montane forest
American Journal of Primatology, 2019Co-Authors: Hanlan Fei, Pengfei Fan, Carolyn ThompsonAbstract:Considering the high energetic costs of maintaining constant body temperature, mammals must adjust their thermoregulatory Behaviors in response to cold temperatures. Although primate daytime thermoregulation is relatively well studied, there is limited research in relation to nighttime strategies. To investigate how Skywalker hoolock gibbons (Hoolock tianxing) cope with the low temperatures found in montane forests, we collected sleep-related Behavior data from one group (NA) and a single female (NB) at Nankang (characterized by extensive tsaoko plantations) between July 2010 and September 2011, and one group (BB) at Banchang (relatively well-managed reserve forest) between May 2013 and May 2015 in Mt. Gaoligong, Yunnan, China. The annual mean temperature was 13.3°C at Nankang (October 2010 to September 2011) and 13.0°C at Banchang (June 2013 to May 2015) with temperatures dropping below -2.0°C at both sites, making them the coldest known gibbon habitats. The lowest temperatures at both sites remained below 5.0°C from November to March, which we, therefore, defined as the "cold season". The hoolock gibbons remained in their Sleeping trees for longer periods during the cold season compared to the warm season. Sleeping trees found at lower elevations and closer to potential feeding trees were favored during cold seasons at both sites. In addition, the gibbons were more likely to huddle together during cold seasons. Our results suggest that cold temperatures have a significant effect on the Sleeping Behavior of the Skywalker hoolock gibbon, highlighting the adaptability of this threatened species in response to cold climates.

antipredation Sleeping Behavior of skywalker hoolock gibbons hoolock tianxing in mt gaoligong yunnan china
International Journal of Primatology, 2017Co-Authors: Hanlan Fei, Dao Zhang, Shengdong Yuan, Lu Zhang, Pengfei FanAbstract:Studying Sleeping Behavior can provide key information for understanding the ecology of a species. Antipredation is an important factor that affects primate Sleeping Behavior. We studied antipredation Sleeping Behavior in skywalker hoolock gibbons (Hoolock tianxing). We studied one group (NA) and a solitary female (NB) at Nankang from July 2010 to September 2011, and another group (BB) at Banchang from May 2013 to December 2014 in Mt. Gaoligong, Yunnan, China. Over the study period, we recorded 67 Sleeping trees for members of group NA over 92 days, 17 trees for the solitary female NB over 22 days, and 159 trees for members of group BB over 186 days. Skywalker hoolock gibbons at both sites rarely used the same tree on consecutive days (N = 3 at both sites). They traveled fast to enter Sleeping tree a mean of 160 ± SD 43 min before sunset at Nankang, and a mean of 192 ± SD 40 min before sunset at Banchang. They seldom (Nankang: 14%, N = 183 observations; Banchang: 25%, N = 548 observations) defecated in Sleeping trees. They slept at sites with more tall and large trees and preferred to sleep on tall trees in the site. They slept on branches of small diameter and closer to tree tops. Our study suggests that antipredation plays an important role in skywalker hoolock gibbons’ Sleeping tree selection and Sleeping Behavior. In addition, our data suggest potential effects of habitat degradation on gibbons’ Sleeping Behavior. Tall trees are especially important for gibbons in degraded forest and should be protected.
