中文摘要:

国内有关鸟类胚胎心率的研究较少。2014年5-8月,在黑龙江扎龙国家级自然保护区,利用红外胚胎心率测量仪对家燕(Hirundo rustica)和金腰燕(Cecropis daurica)的卵胚胎心率进行了测量,以比较两种同域繁殖的近缘鸟种在孵化期的胚胎心率变化。两种燕均在孵化的第二天开始出现胚胎心率,并随孵化天数呈上升趋势,但家燕在第8天(Day 8: t =-2.602, P=0.009；)、第11-14天的胚胎心率显著低于金腰燕(Day 11: t =-2.801, P =0.01; Day 12: t =-2.739, P =0.015; Day 13: t =-4.315, P=0.001; Day 14: t =-6.247, P=0.000)。两种燕的卵胚胎心率日均增长差异不显著(家燕: 19.03±3.1 BPM, 金腰燕: 16.1± 3.4 BPM, t=-2.029, P=0.053)。两种燕的胚胎心率与卵容量和卵重均不存在显著相关性(家燕: 卵容量1.73± 0.09 cm₃, r = 0.192, P = 0.511; 卵重1.74± 0.09 g, r=0.128, P=0.663; 金腰燕: 卵容量1.74±0.08 cm₃, r =0.04, P= 0.891; 卵重1.51± 0.09 g, r=0.054, P=0.855)。

英文摘要:

To date, egg embryonic heart rate in birds has been poorly understood in China. During the breeding season from May to August in 2014, egg embryonic heart rate of Barn Swallow (Hirundo rustica) and Red-rumped Swallow (Cecropis daurica) in Zhalong National Nature Reserve, Heilongjiang, Northeastern China, were measured using the Buddy Digital Egg Monitor. The results showed that egg embryonic heart rate of both swallows increase with incubation days in general. Embryonic heart rate of the Barn Swallow was significantly lower than that of the Red-rumped Swallow in Day 8 (t=-2.602, P=2.602) and Day 11 to14 (Day 11: t = -2.801, P=0.01; Day 12: t=-2.739, P=0.015; Day 13: t=-4.315, P=0.001; Day 14: t= -6.247, P=0.000). However, there was no difference on daily growth of embronic heart rate between Barn Swallow and Red-rumped Swallow (Barn Swallow: 19.03±3.1 BPM, Red-rumped Swallow: 16.1± 3.4 BPM, t=-2.029, P=0.053). In addition, there was also no correlation between daily growth of embryonic heart rate and egg volume, or egg mass in both species ( Barn Swallow, egg volume: 1.73± 0.09 cm₃, r=0.192, P=0.511; egg mass: 1.74± 0.09 g, r=0.128, P=0.663; Red-rumped Swallow, egg volume: 1.74±0.08 cm₃, r= 0.04, P=0.891; egg mass: 1.51± 0.09 g, r=0.054, P=0.855).
