热对水生繁殖力的影响
虽然较高的温度可能对生物直接致命,但最近的研究表明,高温对生育力的影响可能更好地预测物种灭绝和栖息地范围的限制。生殖生理对热应激特别敏感,对一系列生殖性状有潜在影响,包括配子质量、受精过程和后代早期发育。鉴于气候的持续变化,有必要更好地了解和预测生殖对热胁迫的敏感性。为了提供见解,英国圣安德鲁斯大学的Amber Chatten和英国的同事进行了一项荟萃分析,纳入了241个海洋和淡水物种以及1894个生殖性状效应大小。它们在对生育力的热效应的大小和方向上都显示出很大的变化,有些物种在变暖的情况下生育力有所提高。影响在海洋、淡水或其他水生动物之间没有明显差异,在门之间也没有明显差异,但有一些证据表明,温度对外部肥料的影响比内部肥料的影响更大。如果生物在早期发育阶段就暴露在高温下,温度升高也会产生更强的影响。这对女性来说尤其如此,女性的生育率比男性下降得更多,这与人们普遍认为男性的生育率对压力更敏感的观点形成了鲜明对比。
