abundances-S California 2003.xls

Proportional abundances of bivalve species in living and death assemblages sampled on the southern California shelf. Living assemblages are represented by unpublished data from the 1975 BLM-funded survey conducted by Alan Hancock Foundation, which we have digitized from rescued print-outs. Death assemblages - data generated by authors of this paper from unprocessed sieve residues of these same samples, archived by the Los Angeles County Museum of Natural History. Mesh size 2 mm. In this study, 2 habitats are represented by sandy muds and muddy sands ranging from 30 to 90 meters of water depth. All stations are outside the impact areas of publicly operated wastewater outfalls. See the excel file with environmental assignment and samples sizes for each station (sample size can be used to recompute proportional into absolute abundances).
