Three short geomagnetic excursions, the Go thenburg, Mono Lake and Mungo in the Brunhes Positive Polarity period, were revealed based on the studies of magnetostratigraphy, susceptibility and δ^18O of sediments in core WP 92-5 from the central temperature area of the Western Pacific Warm Pool, and the ages of them are 12.1--11.3 kaBP, 25.0--24.0 kaBP, and 31.0--28.0 kaBP respectively. Furthermore, the Younger Dryas and Heinrich cold events were also discovered in this core by the susceptibility record.

The contents of metal elements Zn, Ba and Cu in lagenal otoliths were lower than those in saccular otoliths. Conclusion The contents of magnetic elements in lagenal otoliths of homing pigeons are not much higher than those in utricular and saccular otoliths, which does not support the hypothesis that birds depend on high contents of Fe and Zn in lagenal otoliths for sensation of geomagnetic information.

结果表明成年信鸽瓶状囊耳石中磁性元素的含量极低而且不比内耳球囊和椭圆囊耳石更丰富，从而不支持信鸽因其瓶状囊耳石中含有较高的Fe、Zn等元素而能够感受地球磁场这一假说。
