瑶山髭蟾生态习性的研究

A STUDY OF ECOLOGY AND HABIT OF VIBRISSAPHORA YAOSHANENSIS

瑶山髭蟾主要分布在广西大瑶山香炉冲海拔1000～1500m.周年大部分时间都栖于陆地土穴、石洞内,通常夜出昼伏,杂食性。仅在繁殖期即每年12月“冬至”前后的10天左右才下到山溪水流中产卵,卵群呈团状,粘附在石块腹面的凹陷处。每次产卵约320粒左右,卵径3.8～4mm. 它们在严冬季节,水温10℃以下仍照常活动,因此,很可能没有“冬眠”期,或“冬眠”期极短。

The member of Vibrissaphora yaoshanensis live natural environment which is 1 000-1 500 m above sea level. They conceal themselves in shady and damp places, under rocks or in soil holes, most of the year live oh land, except breeding period which take place from Heavy snow to winter solstice in December. It lasts about ten days, when they go back to the water. The breeding period is short. When the female and male mate under a rock which lies in flowing water. During the breeding period, the male Vibrissaphora yaoshanensis are much more than the female ones. Generally speaking a Vibrissaphora yaoshanensis begins to spawn after midnight and finish until dawn. Every female Vibrissaphora yaoshanensis spawns about 300~350 eggs on an averge.The diameter of the egg is about 3. 8~4 mm. Sometimes two egg-masses can be found in the same place. The egg-mass adhere to the part of the bottom of the rock which is sunken. The hatching takes place in the flowing water. The Vibrissaphora yaoshanensis spawn only once a year. They can move about below 10℃ in January, perhaps they have no hibernation period or the hibernation period is very short.
