Abstract

气候变暖可能严重影响卵生物种的胚胎发育和幼体生长。由于产卵事件先后发生在整个繁殖季节, 评估气候变暖对卵生物种繁殖的总体影响十分困难。一次成功的产卵除了让胚胎能够完成发育外, 还需要让卵在有利于后代生存和能量积累的时机孵化。我们提出了一个新的指标--产卵机会(EO) --用来估计一年中一窝新产卵能够产生成功越冬后代的时间。结合微气候数据、胚胎发育数据和生物物理模型, 我们估算了模式物种东部强棱蜥(Sceloporus undulatus)在当前气候条件和气候变暖情景下, 其分布范围内的EO。我们预测, 在东部强棱蜥分布区内的11407个位点中, 74.8%的位点的EO将随着气候变暖而缩短。由孵化成功率降低和后代能量积累减少所造成的EO损失(72.6%和72.9%)大于由新生幼体热压力所造成的EO损失(59.9%)。在气候变暖情景下, 增加产卵巢穴深度(12 cm)可能比在更郁闭的巢穴中产卵(50%郁闭)更有效地减缓EO损失, 因为在东部强棱蜥的例子中前者(66.1%)比后者(28.3%)在更多的地点避免了EO的损失。我们提倡使用EO来预测气候变暖对卵生动物的影响, 因为它概括了气候变暖对繁殖生活史各个阶段的综合影响。.
