The information theory measure H'=-∑[p log p ] is partitioned into components to allow evaluation of various contributions to total divesity. If, a species collection is sampled at several microhabitats within each of several sites, we may ask whether the niche breadth of a particular species, and the diversity of the entire collection, are greater with respect to microhabitats or sites. The usefulness of these measures is discussed in the context of within-habitat and between-habitat contribution, to diversity.
信息论测度H′ = -∑[p log p]被划分为多个分量，以便评估对总多样性的各种贡献。如果在几个地点中的每个地点的多个微生境中对一个物种集合进行采样，我们可能会问，特定物种的生态位宽度以及整个集合的多样性，相对于微生境还是地点而言更大。这些测度的有用性将在生境内和生境间对多样性的贡献的背景下进行讨论。
