Biological Regionalisation Data for Australia (from CSIRO Bioregionalisation Project 1996)

This dataset presents an interim provincial-scale bioregionalisation for the shelf region of the Australian EEZ. The regionalisations were derived from RAP (Rapid Assessment Procedure) analyses of available fish distribution data. The dynamic evolution of the marine biota and the extensive mixing of species assemblages is catered for by the introduction of biotones. Bioregions are shown to be extensive and highly diverse, containing species from a number of core provinces. A provincial scale bioregionalisation was derived for the pelagic and demersal systems separately. The pelagic bioregionalisation comprises 4 bioregions (two provinces and two zootones) of much more extensive spatial scale that the demersal bioregionalisation (17 bioregions, 9 provinces and 8 biotones). Distribution maps for approx. 150 key fish species used to construct the bioregions are indexed separately (see graphics link and "related datasets"). The data are also linked to oceanographic regionalisation data (see documentation link for details).

本数据集针对澳大利亚专属经济区（Exclusive Economic Zone, EEZ）的陆架区域，提供一套阶段性省级尺度的生物区划方案。该区划方案基于现有鱼类分布数据的快速评估程序（Rapid Assessment Procedure, RAP）分析所得。通过引入生物群区过渡带（biotones），可兼顾海洋生物区系的动态演化以及物种组合的广泛混合现象。本次构建的生物区划单元分布范围广阔且多样性极高，涵盖了来自多个核心生物省的物种。本研究分别针对中上层与底栖水域系统构建了省级尺度的生物区划方案：其中中上层生物区划包含4个生物区划单元（含2个生物省与2个动物群区过渡带（zootones）），其空间尺度远大于底栖生物区划（后者包含17个生物区划单元、9个生物省以及8个生物群区过渡带）。用于构建该生物区划的约150种关键鱼类的分布地图已单独编制索引（详见图形链接与"相关数据集"条目）。本数据集还与海洋学区划数据相关联，详细信息可查阅文档链接。
