| 摘 要： | 为分析圈养印太瓶鼻海豚与所处水环境间的关系,观测和记录了两只圈养印太瓶鼻海豚一年内的发声、行为及水环境温度、盐度及酸碱度。通过时频滤波和分析,筛选出一年中17:00到08:00内海豚发出的正弦型哨叫声。经统计、比对和相关性分析,得到:正弦型哨叫声发生量与海豚不良情绪行为发生量线性正相关(拟合优度R2=93.89%),8月—10月发生频次最多,此时海豚不良情绪行为也最多;该类型信号发生量占比与所处水环境月平均温度和盐度有关,并拟合出它们的关系式(拟合优度R2=68.61%),但受月平均酸碱度影响不大;水环境月平均温度和盐度在一定范围内时,海豚不良情绪行为发生量占比可以控制在12%以下。研究结果为今后利用海豚哨叫声判断海豚生物行为、健康状况、圈养环境舒适度等提供一定的科学参考。

| Abstract: | In order to analyze effects the water environmental elements on behaviors of captive Indo-Pacific bottlenose dolphins (Tursiops aduncus),vocalizations and emotion related behaviors,water temperature,salinity,acidity and alkalinity were observed and recorded throughout one year.The sinusoidal whistles of dolphins produced from 17:00 to 08:00 were selected by time-frequency filtering and analysis.The results which obtained by means of statistics,comparison and correlation analysis were given as follows: (1) the occurrence proportion of sinusoidal whistles was positively correlated with that of dolphins' negative emotional behavior (goodness of fit R2 = 93.89%).The dolphins produced most sinusoidal whistles between August and October,at the same time the dolphins had most negative emotional behavior. (2) the occurrence proportion of sinusoidal whistles was related to the mean monthly temperature and salinity of the water environment (goodness of fit R2=68.61%).However,the occurrence proportion of sinusoidal whistles was not affected by the acidity and alkalinity. (3) The occurrence proportion of negative emotional behavior in dolphins could be less than 12% when the mean monthly temperature and salinity of water environment were within a certain range.The results of this study provide some scientific references for estimating biological behaviors and physical condition of dolphins and whether the captive environment for dolphins is comfortable or not using whistle signals in the future. |
