THE-MALE-REPRODUCTIVE CYCLE OF THE SKINK EUMECES ELEGANS (SQUAMATA: SCINCIDAE) FROM THE CENTRAL HIGH ALTITUDE AREA OF TAIWAN

台灣中部高海拔麗紋石龍子雄性生殖週期之研究

摘要


Seasonal gonadal variation in the male oviparous skink, Eumeces elegans, is presented. Males exhibited testicular recrudescence in August and maximal testis mass occurred during September and October. Spermatogenetic activity regressed during April through July, when seminiferous tubules were mostly occupied by spermatogonia and few spermatocytes. Spermiogentic activity, significantly correlating with the testis mass, attained to its peak in September and October. Fat body mass increased to its peak in the pre-dormancy month, October. Neither temperature nor rainfall showed any correlation with testicular activity and testis mass.

本研究描述卵生麗紋石龍子雄性生殖之季節性變化。雄蜥睪丸於八月復萌,九至十月睪丸重量達到最高峰。生精活動於四至七月降至最低,此時細精管僅由精原細胞及少數的精母細胞所構成。精子生成與睪丸重量呈正相關皆於九至十月達到最高峰。脂肪體重量於冬眠前的十月達到高峰。睪丸週期及重量與溫度及雨量無顯著相關。
