新加坡无尾两栖类5科7种全年繁殖。在性腺，泌尿生殖道和第二性征的条件波动是不规则的，不能与几乎季节性气候的变化。繁殖行为更频繁地观察到在大雨期间，特别是在Microhylidae。Leptobrachium nigrops（Pelobatidae）单独变得更加繁殖活跃在干燥的法术。这些结果表明，不存在任何固有的年生殖周期。
Seven species from the 5 families of Singapore anurans were found to breed throughout the year. Fluctuations in the condition of gonads, urino-genital tracts and secondary sex characters were irregular and could not be correlated with changes in the virtually aseasonal climate. Reproductive behavior was observed more frequently in periods of heavier rain, especially in the Microhylidae. Leptobrachium nigrops (Pelobatidae) alone became more reproductively active during drier spells. Absence of any inherent annual reproductive cyclicity is indi-cated by these results.
