- The high haplotype diversity and nucleotide diversity were corresponding to very large population size and extensive distribution of Pelophylax nigromaculata in Palaearctic Region and Oriental Region. 这样高的单元型多样性和核苷酸多样性与黑斑侧褶蛙作为古北界和东洋界的广布种,种群大是相应的。
- The song of Rana nigromaculata was composed of four pulses,the pulse rate(PR) was 8-11 times/sec,the duration of each song was about 370-510 ms,each pulse had three power peaks,and the frequency of highest power peak was between 2.0 and 2.4 kHz. 黑斑蛙鸣声一般由4个较长的脉冲组成,每个脉冲持续时间30-50ms,脉冲率(PR)8-11个/s。 每声持续时间370-510ms,各脉冲的能量主要集中在3个能峰上,主能峰位于2.;0-2
- In P. nigromaculata, clutch size was closely correlated with the snout-urostyle length and body mass, by indicating that the female frogs could increase reproductive outputs increasing body sizes. 黑斑侧褶蛙雌体怀卵数量与体长和体重皆成正相关关系,表明黑斑侧褶蛙通过增加个体大小增加繁殖输出。
