物种多度分布的一般理论

The general theory of species abundance distributions

Michael G. Bowler, Colleen K. Kelly

摘要:

今天生态学的一个中心问题是决定自然群落中物种相对丰富度的因素。将统计物理学的原理适当地应用于物种丰度分布(SAD)问题,使我们能够确定对所观察到的近乎普遍的特征负责的基本生态学原理。这些原则是(i)限制生态行会中的个人数量和(ii)人均出生率和死亡率。因此,我们统一了Hubbell [1]的中性学说〈动〉<动>、Volkov等人[2,3]的主方程方法和最近尝试部署统计力学来处理这个问题的Pueyo等人[4]的特殊[极端小生境]理论;我们在[4]中确定了先验的真正起源。我们还发现,在我们的研究结果清楚地表明,生态位必须是非常灵活的,各种规模的时间波动是相当重要的社区结构。

英文摘要:

A central issue in ecology today is that of the factors determining the relative abundance of species within a natural community. The proper application of the principles of statistical physics to the problem of species abundance distributions (SADs) has enabled us to identify the fundamental ecological principles responsible for the near universal features observed. These principles are (i) a limit on the number of individuals in an ecological guild and (ii) per capita birth and death rates. We thus unify the neutral theory of Hubbell [1], the master equation approach of Volkov et al [2, 3] and a recent attempt at deploying statistical mechanics to deal with this problem, the idiosyncratic [extreme niche] theory of Pueyo et al [4]; we have identified the true origin of the prior in [4]. We also find in our results clear indications that niches must be very flexible and that temporal fluctuations on all sorts of scales are of considerable importance in community structure.
