Full description

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).

Statement: A biogeographically informative subset of genera was determined using a 'rapid assessment procedure' (RAP) and ranked by a "Biogeographic Information Index". This was followed by delphic regionalisation based on fish distribution information supplied by expert taxonomists, an objective analysis of boundary coincidence using all the refined species from a BioTax workshop, and an analysis of the dissimilarity in species distribution as represented by a variation of the Jaccard index (Jaccard, 1912) and its extension to the two-dimensional domain for Bass Strait, as developed in this project. A string analysis was then performed, and two algorithms for peak-detection were employed. The first was a global search which required a peak to be larger by a prescribed factor than the average number of string boundaries in a bin. In the second scheme, denoted as a local peak, the peak was required to be larger by a prescribed factor than the median of a sample from a number of bins adjacent to the bin being examined. Both of these peak detectors were then run for a range of realisation of the parameters of the filters (filter width range of 3 - 9 bins, multiplication factor range 2.5 - 3.5).
