摘要
2007年10月至2008年4月在海南大田国家级自然保护区文昌保护站,采用焦点动物取样法和全事件取样法逐日观察了海南坡鹿的昼间行为节律。结果表明,坡鹿在晴天有2个摄食高峰,雨天则出现4个摄食高峰;晴、雨天均出现2个反刍高峰与2个休息高峰,1个移动高峰。Mann-Whitney UTest法统计检验结果表明,在晴天,雄性坡鹿和雌性坡鹿反刍行为差异显著(P<0.05),休息与移动行为差异极显著(P<0.01),摄食和其他行为差异不显著(P>0.05);在雨天,雄性坡鹿和雌性坡鹿摄食、反刍、休息、移动和其他5个类型的昼间行为差异均不显著(P>0.05)。
The diurnal activities of an enclosed population of Hainan eld＇ s deer （ Cervus eldi hainanus） at Wenchang Station, Datian National Nature Reserve, were observed and recorded from October 2007 to April 2008 by using focal animal sampling and all - occurrence sampling method. The activities were divided into 5 types, i.e. feeding, rtuninating, rest, moving and other behaviors. Mann - Whitney U - test was used to analyze the effects of rainfall on the diurnal time budget and activity rhythm of Hainan eld＇ s deer. The time when males spent in ruminating was significantly different from that of females on the sunshine days （ P 〈 0.05）. A significant difference existed in rest and moving time between male and female deer on the sunshine days （P 〈 0.01 ）. There was no difference in five behavior types between male and female deer on the rainy days （ P 〉 0.05）. Two feeding peaks of both sexes were observed on the fine days,but there were four feeding peaks on the rainy days. There were two rumination peaks, two rest peaks and a moving peak on both fine and rainy days.
