Relationship between observed (Mobs) and predicted mortalities (Mpred) resulting from formulae LD1989 (Larinier and Dartiguelongue, 1989), BL2000 (Bosc and Larinier, 2000), UDL and QHL (see text), and variability of errors (difference between Mpred and Mobs) in relation to Mobs. r = Pearson coefficient of correlation between Mpred and Mobs, RMSE = root mean square error, straight lines on graphics represent Mpred = Mobs n = number of available data.
