Brief description
The objective is to synthesize published information on sponge distributions and biodiversities in North-West Australia, with an additional focus on extracting data from Western Australian Museum (WAM) specimen databases and collections, and analysing and collating these datasets to provide an overall synthesis of the sponge faunal biodiversity and distributions of the NW.Lineage
Statement: Data on collection effort were compiled from records of all expeditions and collecting trips associated with the WAM and ALA databases. In addition, all other historic expeditions and records that had reported sponge presences not captured in these databases were electronically summarised and collated (commonly from the 1970s and 1980s; Table S2). Collection effort was summarised in three ways for each bioregion: (1) number of collection days, (2) number of collection stations and (3) area of benthos surveyed based on collecting methods (intertidal walks, SCUBA/snorkel, trawls, epibenthic sled). Regression analyses compared the number of collection stations and sampling days, with number of stations where sponges were found, thus investigating the effects of collection effort on sponge presence for each bioregion.Created: 13 12 2013
