Abstract

The ideal free distribution, a theoretical model of the distribution of competitors between habitat patches, has recently undergone a number of modifications and extensions. These fall into two main categories: those that assume that equilibrium is attained, and those that establish whether it is attained. The modifications suggest ways in which behavioural properties of individuals might affect the distribution of competitors, and clear a path for further empirical tests.

摘要

理想自由分布,一种栖息地斑块间竞争者分布的理论模型,最近经历了一些修正和扩展。这些修正分为两类:一类假设达到了平衡,另一类则确定是否达到了平衡。这些修正提出了个体行为特性可能影响竞争者分布的方式,为进一步的实证检验开辟了道路。
