崇安地蜥断尾再生与产卵行为初报

Preliminary Studies on Tail Regeneration and Oviposition Behavior of Platyplacopus sylvaticus

在实验室条件下观察了崇安地蜥(Platyplacopus sylvaticus)的断尾再生和产卵行为.结果显示,雌雄地蜥断尾再生速度都呈逻辑斯谛曲线状.崇安地蜥为多次产卵型,窝卵数2～4枚;产卵前1天就表现焦躁不安,不食;每窝生殖投入分别为0.313、0.152、0.159和0.198,平均为0.206,其中后三窝是在断尾再生的同时产出的.断尾再生时减少生殖投入,断尾生长速度不受生殖投入的影响.

In the laboratory, we observed the regeneration of severed tail and oviposition behavior of Platyplacopus sylvaticus. The results showed that the regeneration speed of severed tail of the male and female were all present logistic curve. The Platyplacopus sylvaticus belongs to multi-oviposition type, clutch sizes 2～4. And one day before oviposition, they expressed fretful discomfort and did not eat. The reproduction investments of each clutch are 0.313, 0.152, 0.159 and 0. 198, respectively, average for 0.206. However, the regeneration of .severed tail and the last three ovipositions are at the same time. Regeneration of severed tail reduces the reproduction investment; however, regeneration speed of severed tail is not influenced by the reproduction investment.
