广西弄岗家燕种群的卵胚胎心率
Embryonic Heart Rate of Hirundo rustica in Nonggang, Guangxi

中文摘要：2014年4-7月,利用红外胚胎心率测量仪对广西弄岗地区家燕 Hirundo rustica的卵胚胎心率进行了测量。该种群的家燕在孵化的第4天才开始出现卵胚胎心率,且卵胚胎心率随孵化天数呈上升趋势,并在第13天达到最高值(280.5 BPM±23.0 BPM, t=3.855, P<0.002)。家燕的卵胚胎心率日均增长为16.1 BPM±3.4 BPM,但与其卵容量和卵质量均不存在相关性(卵容量1.74 cm 3±0.08 cm 3, r=0.093, P=0.827; 卵质量1.51 g±0.09 g, r=0.043, P=0.920)。
英文摘要：During the breeding season from April to July in 2014, embryonic heart rate of barn swallow ( Hirundo rustica) in Nonggang, Guangxi, was measured using Buddy Digital Egg Monitor. The results showed that the embryonic heart rate of H. rustica started after three days of incubation, and increased with incubation time in general, with the highest of 280.5 BPM±23.0 BPM on day 13 ( t=3.855, P<0.002). The daily growth of embryonic heart rate was 16.1 BPM±3.4 BPM, but there was no correlation between daily growth of embryonic heart rate and egg volume or egg mass (egg volume: 1.74 cm 3±0.08 cm 3, r=0.093, P=0.827; egg mass: 1.51 g±0.09 g, r=0.043, P=0.920). 2016,(1): 93-96 收稿日期：2015-06-17 DOI：10.11984/j.issn.1000-7083.20150211 分类号：Q959.7 基金项目：国家自然科学基金项目(31272328, 31472013); 教育部新世纪优秀人才支持计划项目(NCET-13-0761) 作者简介：陈敏(1989-), 女, 硕士研究生, 研究方向为鸟类生态学 *通讯作者：梁伟, E-mail:liangwei@hainnu.edu.cn 参考文献： 黄俞淞, 吴望辉, 蒋日红, 等. 2013. 广西弄岗国家级自然保护区植物物种多样性初步研究[J]. 广西植物, 33(3): 346-355. 杨岗, 陆舟, 余辰星, 等. 2012. 广西弄岗穂鹛不同季节的觅食地选择[J]. 动物学研究, 33(5): 433-438. 郑光美. 2012. 鸟类学[M]. 北京: 北京师范大学出版社. 周放. 2011. 广西陆生脊椎动物分布名录[M]. 北京: 中国林业出版社.
