Database for Rank Abundance Distribution prediction in the South East Marine Region (SEMR). Version 1.0

This product represents the predicted spatial patterns of species abundance, species richness and species evenness of demersal fish communities in the SEMR. It provides a description of the structure rather than the composition (i.e. specific species) of these assemblages. Structure equates to total species abundance (the total number of individuals), species richness (the total number of species) and species evenness (relative proportions of species). The product can also be used to identify areas in the SEMR that are predicted to have unique combinations of species richness and evenness. This allows managers to identify areas that are predicted to have common or rare types of community structure.

本数据集产品展示了SEMR海域底栖鱼类群落（demersal fish communities）的物种丰度（species abundance）、物种丰富度（species richness）与物种均匀度（species evenness）的预测空间分布格局。该数据集描述的是此类群落集合体的结构特征，而非其物种组成（即具体物种种类）。此处的群落结构等同于总物种丰度（即个体总数量）、物种丰富度（即物种总种类数）与物种均匀度（即物种间的相对占比）。本数据集产品还可用于识别SEMR海域内经预测具备独特物种丰富度与均匀度组合的区域，这可帮助管理者甄别经预测具备常见或稀有群落结构类型的区域。
