贵州疣螈越冬生态的观察

THE Obseravation of Tylototriton Kwzichowensis' Overwinter Ecological

为进一步完善贵州疣螈冬眠的生态生物学资料,采用野外定期定点与室内观测相结合的方法,研究了贵州疣螈(Tylototriton kwzichowensis)的越冬生态。结果表明:贵州疣螈在毕节七星关地区的冬眠时间约在2011年11月13日至2012年3月17日,历时4个月左右。以群居及独居方式冬眠。冬眠场所的选择包括乱石堆石缝、石灰岩山脚石洞、沟塘边泥洞、林下枯枝烂叶和水塘角腐殖土。仅有浅冬眠和中冬眠,无深冬眠,随气温波动,二者可交替出现。低温及其出现的早晚是启动其冬眠的主要生态因子,冬眠期间温度的变化引起冬眠行为的改变,冬眠期还伴随有冬眠生理指标的变化。

The orerwinter ecology of Tylototriton Kwzichowensis were studied by combining the methods of observations at fixed-position at regular in field and a＇t room from October 2011 to April 2012 . The results show that the hibernation period of Tylototriton Kwzichowensis in Qi Xingguan of Bijie is aboutl 1.13th. 2011 - 3.17th. 2012 and it last four months. The hibernation of it is mainly gregarious or living alone. The place where they choose to live inelude：riprap swallet, limestone foot of a moutain cave, ditch pond mud hole, undergroth twigs and rotten leaves,the humus of the bottom of the pond. It has the light hibernation and middle hibernation only. so, deep hiberation is imposssible for them. It fluctuation aecordinng to the temperature. Sometimes,it can replace others to emerge. The low temperature and the time it appears early or late is the main Ecological factors to promote the hiberation. During the hibernation,the ehangable temperature can cause the altering of hibernation act. The period of Hibernation also accompany the diversification of Hibernation Physiological Indicators.
