摘要

费雪原理指出,除非在养育成本上存在性别差异,否则物种应以1:1的比例繁殖后代。跨分类群的研究发现,动物会改变其后代的性别比例,以最大限度地提高个人适应性,以应对各种生态和生物变量。这一现象在鸟类中得到了很好的研究。专业管理的种群为研究众多变量对性别分配策略的影响提供了一个有用的框架。由于对保育和福利的影响,动物机构可能特别有兴趣调查这一现象。我们分析了一个大型数据集,其中包含超过100万只动物园饲养的鸟类的人口统计数据,以研究物种特定的后代性别比例偏差。计算了19867只动物园孵化的水坝的后代性别比,计算了25目277种水坝的后代性别比中位数。我们使用带有Holm Bonferroni alpha标准的Wilcoxon符号秩检验来确定物种中位数是否与parity不同。只有一个物种在一个时期内表现出显著的物种后代性别比例中位数。讨论了我们数据集的局限性。我们建议未来的研究应进一步探讨动物设施内物种性别分配策略的决定因素。

Identifying Offspring Sex Ratio Skews in Zoological Facilities Using Large Historical Datasets
The Fisher principle states that species should produce offspring at a ratio of 1:1 unless there are sex-specific differences in rearing costs. Research conducted across taxa has found that animals will vary the sex ratio of their offspring so as to maximize personal fitness in response to various ecological and biological variables. This phenomenon has been especially well studied within the Avian class. Professionally managed populations provide a useful framework within which to study the impacts of numerous variables on sex allocation strategies. Zoological facilities may be especially motivated to investigate this phenomenon due to corresponding conservation and welfare implications. We analyzed a large dataset containing the demographic data of over 1 million zoo-housed birds for species-specific offspring sex ratio biases. The offspring sex ratios of 19,867 zoo-hatched dams were calculated, and the median offspring sex ratio of 277 species from 25 orders was calculated across two 20-year time periods. We used a Wilcoxon signed rank tests with a Holm Bonferroni alpha criterion in order to determine if species medians differed from parity. Only one species in one time period displayed a significant species median offspring sex ratio. The limits of our dataset are discussed. We propose that future research should further explore the determinants of sex allocation strategies for species held within zoological facilities.
