Fig. D1. Relationships between the temporal change of the size of Daphnia post-abdominal claws and fisheries catches in (a) Lake Geneva, (b) Lake Bourget and (c) Lake Annecy. Spearman’s rank correlation test between Daphnia claws size and catches, Lake Geneva: ρ = -0.511, P = 1.58 × 10-6; Lake Bourget: ρ = -0.340, P = 0.009; Lake Annecy: ρ = -0.426, P = 0.008. Catches correspond to annual catches of whitefish for Lake Annecy and annual catches of whitefish, perch and roach for Lakes Bourget and Geneva. Data of catches were available from the database SOERE-INRA of Thonon-les-Bains – France.
