2022年5-7月,通过野外实地观察,在云南文山国家级自然保护区对蔡氏疣螈Tylototriton ziegleri的成体形态和胚胎发育进行研究,以期了解蔡氏疣螈的成体和胚胎的形态特征。结果显示,蔡氏疣螈雌雄两性的形态特征存在明显差异,雌性整体形态指标更大。雌性全长115。50~135。42 mm,雄性全长102。70~126。79 mm,两性异形指数为0。078。个体的全长、头体长、头长、头宽、吻长和腋至跨距在两性间的差异极显著(P<0。01),躯干长、眼间距、鼻间距、尾长和尾宽在两性间的差异显著(P≤0。05)。胚胎发育共有21个时期,历时(532。49±45。52)h。本研究通过对蔡氏疣螈形态和胚胎发育的详细观察,为有效保护该物种提供了科学依据。
Morphological Characteristics of the Adult and Embryonic Tylototriton ziegleri in China
In this study,to examine the adult morphology and embryonic development of Tylototriton ziegleri,field obser-vations were conducted from May to July 2022 in the Wenshan National Nature Reserve(Yunnan Province,China).The results showed that the female newts had larger overall morphometric measurement than the males.The total length of the female newts ranged from 115.50 mm to 135.42 mm,while the males ranged from 102.70 mm to 126.79 mm.The sexual dimorphism index was 0.078,indicating a significant sexual dimorphism.Various morphological parameters,including to-tal length,snout-vent length,head length,head width,snout length,and axils to span,displayed highly significant corre-lations between females and males.Additionally,trunk length,interorbital space,nasal spacing,tail length,and tail width exhibited significant differences between females and males.The embryonic development encompassed 21 stages with a total duration of 532.49 h±45.52 h.This detailed examination of T.ziegleri's morphology and embryonic develop-ment provides valuable scientific basis for the effective conservation of this species.
