Amphibians exhibit unusually diverse reproductive modes, including a wide array of parental care strategies. The evolutionary drivers of this diversity, however, remain unclear. Here, we investigate three major factors that might predict interspecific variation in parental care strategies: climate, intrasexual selection and social environment. We hypothesize that some forms of care evolved to cope with harsh conditions, such as dry or unpredictable habitats. We contrast this prediction with the hypothesis that parental roles have co‐evolved with the social environment and mating systems.

气候和交配系统是青蛙父母育儿全球多样性的驱动力

两栖动物表现出异常多样的生殖方式，包括多种父母护理策略。但是，这种多样性的进化驱动因素仍然不清楚。在这里，我们调查了可预测父母护理策略中种间差异的三个主要因素：气候，性选择和社会环境。我们假设某些护理形式已经发展为应对恶劣条件，例如干燥或不可预测的栖息地。我们将此预测与父母角色与社会环境和交配系统共同发展的假设进行对比。
