平均性别比和人口维持成本

Average sex ratio and population maintenance cost

Eduardo Garibaldi, Marcelo Sobottka

摘要:

种群中雄性与雌性的比例是有性物种的一个有意义的特征。自然界的观察者之所以能够获得这种生物特性,其原因似乎是一个从未被问过的问题。引入的概念,历史上适应人口的维护成本函数的全球最小化,我们提出了一个理论解释报告的稳定性,这一功能。这个数学公式表明,性别比可以被认为是人口规模和资源有限性之间的对抗所形成的间接结果。

英文摘要:

The ratio of males to females in a population is a meaningful characteristic of sexual species. The reason for this biological property to be available to the observers of nature seems to be a question never asked. Introducing the notion of historically adapted populations as global minimizers of maintenance cost functions, we propose a theoretical explanation for the reported stability of this feature. This mathematical formulation suggests that sex ratio could be considered as an indirect result shaped by the antagonism between the size of the population and the finiteness of resources.
