摘要

摘要异质性一词的定义方式多种多样，使得异质性的含义变得模棱两可。然而，异质性可以被仔细地定义为对多种单一类型的潜在变异的不同反应，即二级变异(或“元变异”)。异质性的识别受到多种因素的影响，包括研究人员的决策，特定规模的生态系统可以包含异质性和同质变量。形式化的定义也可以减少异质性比同质性更有益的说法。

Defining heterogeneity as a second level of variation

Abstract. The term heterogeneity has been defined in various ways so that the meaning of heterogeneity has become ambiguous. However, heterogeneity can be defined carefully as a distinct response to multiple single types of underlying variation, that is, a secondary level of variation (or "metavariation"). Identification of heterogeneity is affected by multiple factors, including researcher decisions, and ecosystems at a specified scale can contain both heterogeneous and homogenous variables. A formalized definition may also reduce the suggestion that heterogeneity is more beneficial than homogeneity.

期刊介绍： Web Ecology (WE) is an open-access journal issued by the European Ecological Federation (EEF) representing the ecological societies within Europe and associated members. Its special value is to serve as a publication forum for national ecological societies that do not maintain their own society journal. Web Ecology publishes papers from all fields of ecology without any geographic restriction. It is a forum to communicate results of experimental, theoretical, and descriptive studies of general interest to an international audience. Original contributions, short communications, and reviews on ecological research on all kinds of organisms and ecosystems are welcome as well as papers that express emerging ideas and concepts with a sound scientific background.
