| 中文摘要: |
| 为了探究雌性凹耳蛙（Odorrana tormota）生育力与体型参数之间是否存在相关性，测量了黄山浮溪地区23只排卵后雌蛙的体重、体长、头长、头宽、前臂宽、前肢及指长、前肢长、后肢全长、胫长等9个体型参数，并计数每只雌蛙的窝卵数。相关性分析显示，雌蛙的窝卵数和9个体型参数值均呈正相关性（P < 0.05），体长和其他8个体型参数值均呈现正相关性（P < 0.05），以体长为控制变量，偏相关分析显示，窝卵数和体重呈正相关性（P < 0.05），故具有较长的体长、较重的体重特征的雌蛙，可以携带更多的卵，具有更强的生育能力。不同雌蛙个体间的窝卵数差异较大，平均窝卵数为（646.5 ± 37.6）枚（590 ~ 706枚）。大个体雌蛙具有更强的生育力、更大的繁殖输出，可能是导致凹耳蛙两性间异形程度较大（雌大雄小）的重要驱动力。为了探究抱对雌、雄凹耳蛙之间的配对模式，测量了21对抱对雌、雄蛙的上述9个体型参数，分析显示，抱对雌、雄间9个体型参数值均不存在相关性（P > 0.05），未发现凹耳蛙在性选择的过程中采用选型配对模式，雌性凹耳蛙可能倾向雄蛙非体型的品质特征，比如鸣叫声等。 |

| We measured totally 9 types of body characteristic parameters of 23 female frogs (Odorrana tormota) including snout-vent length (SVL), head length (HL), head width (HW), width of lower arm (WLA), length of lower arm and hand (LAHL), forelimb length (FLL), hindlimb length (HLL), tibia length (TL), body mass (BM) in Huangshan Fuxi area after they ovulating to explore whether there is a correlation between fertility and the body characteristic parameters. We found out that the 9 types of body characteristic parameters frogs had significant positive correlation with clutch size (P < 0.05, Table 1). We also found out that SVL was also positively correlated with the rest 8 types of body characteristic parameters (P < 0.05, Table 2). By using the SVL as the control variable, we conducted a partial correlation analysis and got a positively correlation of the clutch size with BM (P < 0.05, Table 3). These results indicated those females who with longer SVL and heavier BM produced a larger clutch size and had a stronger fertility. The clutch size between female individuals was differences with average around 646.5 ± 37.6 (590﹣706). The larger individual females have stronger fertility and larger reproductive output, which may be played an important role for the high degree sexual dimorphism of the concave-eared torrent female frogs. In order to explore what kind of mating patterns do male and female frogs choose, we measured and compared the 9 body characteristic parameters mentioned above from 21 mating paires and found out that the body characteristic parameters did not affect the female frogs selecting their matings (P > 0.05, Table 4). The fact means that the female frogs may prefer males with other quality characteristics, such as croaks. |
