| 摘 要： | [目的]了解东北林蛙在粤北山区4种不同越冬模式下的越冬情况。[方法]在粤北山区设置室外水陆越冬、室外水越冬、室内旱越冬与室内冷冻箱水越冬4种越冬模式,将东北林蛙分别放在这4种越冬模式下进行越冬管理。记录时间、温度以及东北林蛙的越冬情况;同时,对越冬前后的各组东北林蛙分别进行数量统计与体重测量,计算林蛙在越冬期的体重消耗率和成活率。[结果]室外水陆越冬模式与室外水越冬模式中林蛙成活率仅有40.0%与41.5%,室内旱越冬与冷冻箱水越冬模式中林蛙成活率达到了82.0%与84.5%。[结论]温度、越冬模式以及东北林蛙自身的肥满度是影响东北林蛙在粤北山区安全越冬的重要因素。

| Abstract: | [Objective] To understand the overwintering of Rana dybowskii under four overwintering modes in northern Guangdong's mountainous areas.[Method] The overwintering management of Rana dybowskii was performed under four overwintering modes which were outdoor overwintering in water-land,outdoor overwintering in water,indoor overwintering in dryness,and indoor overwintering in freezer,respectively.The time,temperature and overwintering status were recorded.The Rana dybowskii in each group was weighed before and a... |
