摘　　要：2017年12月—2018年11月,首次对云南省德宏傣族景颇族自治州盈江县北部7个高黎贡白眉长臂猿Hoolock tianxing家庭和2只独猿开展了连续1年的鸣声监测。共记录352次鸣叫,高黎贡白眉长臂猿平均鸣叫起始时间在日出后117.97 min±67.1 min(n=352),鸣叫持续时间平均为21.52 min±12.8 min(n=352),独猿和家庭的日鸣叫频次分别为1.1次/天和0.424次/天。广义线性混合模型分析结果显示,日最低温度对高黎贡白眉长臂猿的鸣叫行为有显著影响,长臂猿在低温月份会推迟鸣叫起始时间,但日最低温度对鸣叫持续时间和日鸣叫频次的影响不显著;监测结果表明占据领域的独猿的鸣叫频次高于其他家庭。本研究反映了在生境破碎化栖息地中,低温对高黎贡白眉长臂猿鸣叫行为有显著影响,建议未来开展持续性种群监测和栖息地恢复工作。From December 2017 to November 2018,a one-year continuous singing monitoring was conducted on 7 Hoolock tianxing family groups and 2 solitary individuals occupying territories in the northern part of Yingjiang County,Yunnan.The aim of the study was to investigate the singing behavior of H.tianxing and its relationship with environmental factors in their habitat.A total of 352 singing behaviors were recorded and analyzed,revealing that the average start time of the singing behavior was 117.97 min±67.1 min(n=352)after sunrise,with an average duration of 21.52 min±12.8 min(n=352).The daily singing frequency of family groups was 0.424 times on average,while that of solitary individuals was 1.1 times on average.Generalized linear mixed model analysis was performed to investigate the impact of environmental factors on the singing behavior.The results showed that the daily minimum temperature had a significant impact on the start time of the singing behavior,with delayed onset during colder months.This suggests that H.tianxing may adopt an energy conser⁃vation strategy during cold periods.However,the effect of daily minimum temperature on singing duration and daily sing⁃ing frequency was not significant.In addition,the study showed that the singing frequency of solitary individuals occupying territories was higher than that of other family groups,reflecting the attracting function of the singing behavior.Based on our study,we have observed the impact of low temperature and habitat fragmentation on the singing behavior of H.tianxing.Our findings suggest that in order to effectively protect the H.tianxing,it is recommended to implement continuous popula⁃tion monitoring and habitat restoration initiatives.
