摘要	Data on the activity rhythms and time budgets of Asiatic brush-tailed porcupines (Atherurus macrourus) were collected by camera traps between August 2012 and July 2013 in the 15-ha Forest Dynamics Plot and its surrounding area in Nonggang National Nature Reserve. We used a relative activity intensity index to explore the influences of moon phase and other environmental factors on the activity rhythms and time budgets of porcupines. Results showed that activity intensity varied significantly over the course of the day (t = 4.666,df = 23,P = 0.001), with two activity peaks: one from 20: 00-21: 00 and one from 05: 00-06: 00. Moving (63.2%) and foraging (23.6%) were the main nocturnal activities. There were significant differences in monthly time budgets (t = 8.581,df = 11,P = 0.001), and significant difference between the rainy season and dry season (Z =-2.166,P = 0.03). There were also marked variations in activity frequencies of porcupines during different phases of the moon (chi~2 = 5.00,df = 1,P = 0.025), with the highest activity during the new moon and full moon phases. There were significant negative correlations between monthly activity intensity and monthly rainfall,maximum temperature,and minimum temperature (R~2 = 0.440,R~2 = 0.435,R~2 = 0.457,respectively),and we found the optimal temperature to be between 10℃ and 26℃. This research provides preliminary data for the activity rhythms and time budgets of porcupines in Nonggang,and could help us to understand possible effects on their activity due to ongoing habitat modification and climate change in future research.
其他摘要	2012年8月至2013年7月,采用红外相机技术对广西弄岗国家级自然保护区15 hm~2森林动态监测样地及其周边区域内的帚尾豪猪(Atherurus macrourus)进行观察,采用活动强度指数分析其活动节律和时间分配,探讨月相和环境因子对其活动节律和时间分配的影响。结果表明,不同时间段内帚尾豪猪的活动强度存在极显著差异(t = 4.666,df = 23,P = 0.001), 活动峰值出现在20: 00 ~ 21: 00和05: 00 ~ 06: 00;夜间主要以移动(63.2%)和觅食(23.6%)为主。帚尾豪猪各月份间的时间分配存在极显著差异(t = 8.581,df = 11,P = 0.001), 旱、雨季间的时间分配存在显著差异(Z =-2.166,P = 0.03) 。各月相间帚尾豪猪出现的频次存在显著差异(chi~2 = 5.00,df = 1,P = 0.025), 以新月期和满月期活动最为频繁,上弦月活动最少。相关性分析表明,活动强度指数与月降雨量、月最高温度及最低温度(R~2 = 0.440,R~2 = 0.435,R~2 = 0.457)都存在显著的负相关,帚尾豪猪最适的活动温区为10℃ ~ 26℃。本研究初步掌握了帚尾豪猪在弄岗保护区的活动节律和时间分配,有助于后期理解栖息地和气候变化对其活动的影响。
