摘　　要：2012年5—6月,应用e-Science信息技术,对红碱淖遗鸥的孵卵行为进行了研究。结果表明,不同孵化阶段昼夜间孵卵节律分别为:孵化前期换孵次数6.40±0.45(n=68)、2.37±0.20(n=62),坐巢方向变换35.34±2.12(n=68)、16.16±0.67(n=62),翻卵次数10.81±0.50(n=68)、6.58±0.40(n=62);孵化中期换孵次数2.20±0.12(n=66)、0.52±0.06(n=60),坐巢方向变换18.73±0.85(n=66)、4.28±0.31(n=60),翻卵次数10.14±0.55(n=66)、4.22±0.30(n=60);孵化后期换孵次数1.81±0.10(n=48)、0.53±0.07(n=47),坐巢方向变换15.17±0.75(n=48)、3.87±0.34(n=47),翻卵次数8.65±0.51(n=48)、3.26±0.22(n=47)。当大风或大雨时,对同一孵化阶段的换孵次数、坐巢方向变换和翻卵次数均存在极显著差异(P<0.01)。双亲交替换孵主要集中于04:00—06:00、08:00—10:00、12:00—14:00等时间段内。孵化后期,亲鸟坐巢时长达到601.14±31.16min(n=56)。遗鸥通过调节昼夜间的孵卵节律来控制卵的温度,以保证昼夜间卵胚胎的正常发育。By using e-Science information technology, an investigation was made on the hatching behavior of relict gull （Larus relictus） in the Hongjiannao of Shannxi Province, Northwest China from May to June, 2012. The diurnal hatching rhythms at different hatching stages were as the follows. At daytime, the times of exchanging hatching at the early, medium, and late stages of hatching averaged 6.40±0.45 （n=68）, 2.20±0.12 （n=66）, and 1.81±0.10 （n=48）, the changes of sitting nest direction averaged 35.34±2.12 （ n = 68 ）, 18.73 ＋0.85 （ n = 66）, and 15.17±0.75 （n=48）, and the times of turning eggs over averaged 10.81±0.50 （n=68）, 10. 14±0.55 （ n = 66）, and 8.65±0.51 （ n = 48）, respectively. At night, the times of exchan- ging hatching averaged 2.37＋0.20 （n=62）, 0.52±0.06 （n=60）, and 0.53±0.07 （ n=47）, the changes of sitting nest direction averaged 16.16±0.67 （ n = 62 ）, 4.28±0.31 （ n = 60）, and 3.87±0.34 （n=47）, and the times of turning eggs over averaged 6.58±0.40 （n=62）, 4.22± O. 30 （n=60）, and 3.26±0.22 （n=47）, respectively. On the days with strong wind and heavy rain, there existed significant differences in the times of exchanging hatching, the changes of sit- ting nest direction, and the times of turning eggs over at the same hatching stages, as compared with those on fine days. The time intervals of exchanging hatching by the parents were mainly 04：00-06：00, 08：00-10：00, and 12：00-14：00. At the late stage of hatching, the duration of sitting nest by the parents was as long as 601.14±31.16 rain （n=56）. It was suggested that the parents controlled the egg temperature via regulating the diurnal hatching rhythm to assure the normal development of egg embryo during daytime and night.
