性感:有证据表明哺乳动物的性别分配受气候影响吗?
气候变化预测表明,未来的气候条件将更加炎热和干燥,降雨量也将更加多变。气候条件会影响个体状况,并决定后代的性别比例。气候变化对哺乳动物性别分配的影响是巨大的,但目前人们对其了解甚少。有几种情况可能会出现气候驱动的性别分配反应。在这里,我预测了在更热、更旱的条件下,资源供应受限和社会/空间结构改变的假设情况下,后代性别比例偏差的方向。我在文献中搜索了在野生种群中研究个体的后代性别比偏差受气候影响的现有证据。在 30 项关于气候变量和后代性别比的研究中,并没有发现在 "好 "或 "差 "气候条件下产生儿子或女儿的强有力的方向性支持。我还在文献中搜索了评估自然种群中母性条件和后代性别比的研究(即气候、资源可用性和母性条件之间存在联系)。在这 27 项调查中,有一半报告了母亲 "良好 "条件下所生子的偏好(56%)。我讨论了这一结果如何可能是由于发表偏差造成的,或者它可能表明,资源可用性低有可能导致母亲状况不佳和生育较少的儿子。我考虑了气候导致的后代性别比例失调在种群水平上的保护意义。我讨论了能够解释自然种群中影响后代性别比的多种因素所面临的挑战,并强调在哺乳动物进化生态学的这一重要领域越来越需要更多的研究。

期刊介绍: Mammal Review is the official scientific periodical of the Mammal Society, and covers all aspects of mammalian biology and ecology, including behavioural ecology, biogeography, conservation, ecology, ethology, evolution, genetics, human ecology, management, morphology, and taxonomy. We publish Reviews drawing together information from various sources in the public domain for a new synthesis or analysis of mammalian biology; Predictive Reviews using quantitative models to provide insights into mammalian biology; Perspectives presenting original views on any aspect of mammalian biology; Comments in response to papers published in Mammal Review; and Short Communications describing new findings or methods in mammalian biology.
