狗狗便溺不隨便　受地球磁場影響
Jan 3rd 2014, 00:52

【施旖婕／綜合外電報導】捷克研究人員在近日發現，狗狗不會隨便大小便，牠的便溺位置除了與地軸有關係，更會受地球磁場影響。

據美國《福斯新聞網》指出，捷克大學(Czech University)的研究人員記錄37品種共70頭犬隻，2年來共5582次小便及1893次大便的體位，同時研究這段期間的地球磁場變化。結果發現，狗狗便溺時，身體通常與地軸對齊。當地球磁場穩定時，牠們早上便溺時會靠近西方，下午則靠近東方。但當地球磁場不穩定時，狗狗才有可能隨地大小便。

該研究發表在最新一期《動物學前線》(Frontiers in Zoology)期刊。
