From: Now an empty mudflat: past and present benthic abundances in the western Dutch Wadden Sea
Long- (1950s vs. ca. 2000) and short-term (1996–2005) trends presented as arithmetic means across zones of equal weighting, at Posthuiswad of polychaetes, crustaceans, and molluscs, respectively. H. ulvae was excluded from molluscs (see Table 1 for densities and “Results” for explanation). The groups are determined according to Table 1. That is, for each zone the species occurring in 1956 and those same species in 1996–2005 were used. Note the time-step on the x-axis, and the log-scaled y-axis
