摘要

鱼类和鸟类在季节条件下的个体物候生活史变化有很好的记录。然而,两栖动物作为一个严重受栖息地丧失和破碎化影响的群体,其生活史适应研究相对较少受到关注。在这里,我们提出了3年的数据,在欧洲郊区的绿蟾蜍(Bufotes viridis)种群的生殖活动的时间。我们发现了每年一致的繁殖活动模式,并调查了这些模式是由异时性还是个体属性引起的。体型(代表年龄)、身体状况和性别显著影响生殖活动的时间。然而,大多数个体在其生殖时间范围内表现出相当大的重叠,驳斥了异时亚种群的存在。我们的研究结果可能表明,为了应对危险的环境,人类在生活史上朝着更快的生活方式方向进行了适应。我们建议将进一步的研究重点放在环境条件下的物候变化上,并在两栖动物保护工作中更加重视物候变化。

Body size and condition, not allochrony, affect temporal reproductive patterns in a prolonged breeding anuran.

Individual phenological life-history variations in the context of seasonal conditions are well documented in fishes and birds. However, amphibians, a group heavily affected by habitat loss and fragmentation, have received relatively little attention regarding research on life-history adaptations. Here we present 3 years of data on the timing of reproductive activity in a suburban European green toad (Bufotes viridis) population. We found annually consistent patterns of reproductive activity and investigated whether these were caused by allochrony or individual attributes. Body size (a proxy for age), body condition, and sex significantly affected the timing of reproductive activity. However, most individuals showed considerable overlap in their reproductive timeframe, refuting the existence of allochronic subpopulations. Our findings may indicate life-history adaptations in the direction of a faster lifestyle in response to hazardous environments. We propose to focus further research efforts on phenological variations in the context of environmental conditions, and that phenological variations should be considered more strongly in amphibian conservation efforts.
