Description
Summary:Progress Code: completed Purpose These files are the results of analyses completed for the following paper: Hill, N. A., S. D. Foster, G. Duhamel, P. Koubbi, D. Welsford, and C. R. Johnson. in press. Application of a new community - modelling method to quantify and map the distribution of subantarctic demersal fish assemblages. Diversity and Distributions. More information of the RCP method can be found here: Foster, S. D., G. H. Givens, G. J. Dornan, P. K. Dunstan, and R. Darnell. 2013. Modelling biological regions from multi-species and environmental data. Environmetrics 24:489-499. Demersal fish form an important component of sub-Antarctic ecosystems. While understanding the distribution of key commercial species is the subject of much current research, patterns in the distribution of benthic fish assemblages as a whole and associated diversity has received less attention. Here we combine Australian (source: AAD Random Stratified Trawl Surveys) and French (source: POKER 2006, 2010, 2013) demersal fish datasets with synoptic environmental data to quantify and predict the distribution of fish assemblages across the Kerguelen Plateau. We achieve this by applying a recently developed method, called Regions of Common Profile (RCP), which quantifies distinct environmental regions containing a similar profile of species. The RCP method directly models species simultaneously (rather than dissimilarities or single species at a time) and offers advantages over previous methods in the areas of model diagnostics, the interpretability of model outputs, and providing estimates of uncertainty. We define the contents, environmental correlates and spatial extent of several assemblages across the plateau. The files provided here are the outputs of the RCP analyses. Files KP_RCP_Predictions.csv: Region of Common Profile (RCP) spatial predictions for entire Kerguelen Plateau. The resolution of the grid is 0.1 x 0.1 degrees (Long, Lat, WGS84) and predictions were restricted to depths shallower than 1200 m. The probability of ...
