Below we show data on the observed fluctuations in biomass of 54 European stocks.
Table S1. Biomass fluctuations of 54 European stocks, with indication of number ofyears in the time series, median of inter-annual decline, 90th percentile of inter-annual decline, median of negative amplitudes, and 90th percentile of negative amplitudes. Numbers are fractions of the previous biomass or of the highest biomassat the beginning of a negative amplitude.
